Adding Forms But It's Limited To Text Input Forms?

Nov 14, 2011

how to add forms in javascript, but it's limited to text input forms.

<script type="text/javascript"><!--
function updatesum() {
document.form.sum.value = (document.form.sum1.value -0) + (document.form.sum2.value -0);
}
//--></script>

Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number.

<input type="button" value="D20" onclick="this.form.display.value = Math.round (20 * Math.random())" class="buttonHi" />  <input name="display" type="text" size="6" value="" />

This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15.

Adding New Row With Forms

Mar 27, 2006

I need someone to point me to the write direction here. I know nothing of javascript, and I've tried looking everywhere I can on Google.

I have a drop down of all the sizes I have in a database. I call them to a form with the ID number as the value. What I want is when a user selects a size, it gets added to the table. For example:

<table>
<tr>
<td>Paper</td><td>size</td><td>quantity</td>
</tr>

<!--Repeat this bit with javascript according to the Paper/size chosen on the drop down -->
<tr>
<td>Glossy</td><td>4x6</td><td><input quantity form></td>
</tr>
<!--End repeat here -->

</table>

Adding Form Values & Validation Of Forms

Jul 5, 2010

I'm currently working on a website called 'eXtreme Gaming' I've almost completed it, apart from two things.

- Adding two values on my checkout page for the Grandtotal (I've tried everything, but I'm too much of a noob and have probably missed something small).

- Validation of forms (I don't know where to start here, I've looked on w3schools for tuts etc but I'm having difficulty incorporating it on my site)

Prompt For Adding A Certain Amount Of Sets Of Forms

Aug 15, 2011

I have taken a class and have some experience in JAVA, but I have never used Javascript. I recently took on the task of maintaining my company's new website, and my boss needs a certain function for a form. Here's what I cannot do. I want to have some type of input or menu to be able to pick between 1 and 10. That number will be how many sets of HTML forms will be added (multiple lines of code per number). I am guessing I need a FOR loop and add in document.write("<html>") within it. I know how to do this in JAVA, but I do not know how to get an input (or menu value) to set the counter.

Forms - Adding Values And Searching A Directory Dynamically

Aug 28, 2009

I have a form, and i am trying to add the values of 5 fields into one javascript variable. Then i need an ajax function to search a directory for a php file made from these variables and return a "file exists" or "file doesnt exist" message to the form.

For example, assume the following values have been inputted into the fields;
Field1 (Manufacturer) - Kawasaki
Field2 (Model_Name) - GPZ500
Field3 (Nickname) - None
Field4 (Market) - UK
Field5 (Year) - 2000

Then javascript needs to add the values of Field1 - Field5 (and add a few bits)to create (for example):

Kawasaki_GPZ500_None_UK_2000.php

Then i need ajax to search a web directory for the file above, and if it exists return a link, or if it doesnt exist tell the user it doesnt exist.

im hoping that i can use ajax to do this search without clicking any buttons etc. unfortunately i have very little knowlegde of javascript and ajax and dont have a clue how i can go about implementing this.

i know how to do it by posting the variables to the next page and doing the check using php - but i would like instant validation as soon as the form fields have been entered.

Validating Forms Input

Jan 6, 2006

I am looking for a little help validating a forms input. On the form are key
items which I do not wish to be zero length.

I have wrote the following function:

<script language=javascript>
function ValidateLength(oid, min, max)
{
var txt = document.getElementById(oid);
var length = txt.value.length;
if(length == 0)
{
alert("You must enter your reference, Company Name and Contact Name");
}
}
</script>

However their are still a few issues I would like to work out.

I all it with my forms sumbit event with the following:

<input type="submit" name="Submit" onclick="ValidateLength('txtRef',0,100)"
value="Submit Details">

However that will only check the length of the item txtRef, how can I check
more textbox values? Also how can I stop the form posting if the alert is raised?

Filling Out Forms Without An Input ID?

Jun 5, 2010

I'm trying to fill out a form on this site using JavaScript: [URL]

However, the fields do not have input IDs; they only have span IDs. I've tried using the span IDs, but it doesnsn't work. Here is the code I'm trying to use:

document.getElementById('fn'). value='" FName "';

Where FName is the value I want filled into the field. Could someone please tell me how to use JavaScript to fill in the fields of this form (and check those pesky check boxes)?

Getting Input Values From Forms?

Mar 9, 2011

I'm trying to write some javascript code that will give a user one of two messages (Correct or incorrect) base on whether they answer a question correctly. I have 2 issues that I was hoping someone could help me with:

1) My "incorrect" and "correct" messages all appear on the page load. Is there anyway to start without them being there?

2) More troubling: No matter what I put into the input boxes, the "incorrect" message pops up. Basically I need to better understand how to grab the actual input value (it's commented down below so I think that this should be a quick fix!)

Code:
function showAnswer(blurred,response)
{
var form = blurred.form;
var rbs = form[blurred.name];

[Code].....

Add An Input Element To All Forms Using AppendChild

Nov 5, 2009

I'm trying to add an input element to all forms using appendChild.

The script first searches for input elements with the name of "myinput".

If it finds an input element with that name, it assigns the value "myvalue".

If it can't find an input element with that name, it tries to create a new one for all forms.

What's wrong with my code?

Disabling Input Fields In Forms

Jan 7, 2007

I am having a very hard time figuring out how to dynamically disable certain fields in a form based upon the user's answer to a <select> element.

So, first I have a <select> element to my form asking the user to choose one of three choices, like so:

<SELECT Name="mortgagetype">
<option value='First'>First</option>
<option value='Second'>Second</option>
<option value='Third'>Third</option>
</SELECT>

The next 6 fields are all input fields:

<INPUT Type="text" size="30" Name="Question1">
<INPUT Type="text" size="30" Name="Question2">
<INPUT Type="text" size="30" Name="Question3">
<INPUT Type="text" size="30" Name="Question4">
<INPUT Type="text" size="30" Name="Question5">
<INPUT Type="text" size="30" Name="Question6">

The tricky part is that I want the availability of certain fields to depend on the user's answer to the <select> element that comes first. If they answer "First" then questions 1, 2, 3 and 4 should be disabled. If they answer "Second" then questions 3 and 4 should be disabled and if they answer "Third" none of the questions should be disabled.

Incorrect Input Of Email Address On Forms?

Apr 10, 2009

I should imagine others here have experienced it. The user completes your form, and they unintentionally input their email address incorrectly. Then when you reply to their form, you then get the mailer daemon returning your email! Now, there's a couple of ways that some websites try to solve this problem - some ask the user to input their email address twice, some show the forms results on the next page, so that the user has a last chance to check, before completing the submission. Are there any other ways of trying to ensure that, as much as possible, that the user inputs the correct email address?

Copying Input Array Element Values Between Two Forms?

Nov 3, 2009

I have two forms with identically named arrays on each. I need to copy the values to the second form's array. Here's a simplified version of the HTML:

<form name="mainform">
<input type="text" size="10" name=firstnames[] value="Joe"/>
<input type="text" size="10" name=firstnames[] value="Bob"/>
<input type="text" size="10" name=firstnames[] value="Pat"/>

[Code]....

I'd like to be able to submit hiddenform with the firstnames array equal to ['Joe', 'Bob', 'Pat']. But I seem to be getting an awful lot of ['', '', ''] no matter how I go about it.

Hyperlink (Select Forms) Convert To Text

Oct 7, 2010

Basically what we are trying to accomplish is this... We have a php file in which a hyperlink "Select Forms" is present. What we want to happen is when the "Select Forms" link is clicked on a pop-up window will open. The content of this window is generated from our database and displayed for the user. The php in this window generates a list of checkboxes for the user to select and an "OK" button.

What we want to happen is when the user selects the various checkboxes and clicks "OK" the window closes and the previous "Select Forms" link is converted to text based on the checkboxes selected from the pop-up window. We have the pop-up window already taken care of, as well as the php codes. We are having a hard time getting the php variables for the checkboxes transferring to the previous window and converting that link to the text variables.

Radio Button Forms - How To Display Text

Feb 2, 2011

The following code will output numerical values only for the <label>. I need it to display text with multiple characters. For example: I own two exceptional chickens...I own four or more chickens...etc. Again the code works perfectly but only for numbers.

Code:
<script type="text/javascript">// <![CDATA[
function check(x) { document.getElementById('Radio1').innerHTML = x; }
// ]]></script>
<form> <input id="r1" onclick="check(one big);" name="r1" type="radio" value="one" /> One
<input id="r1" onclick="check(two exceptional);" name="r1" type="radio" value="two" /> Two
<input id="r1" onclick="check(three terrific);" name="r1" type="radio" value="three" /> Three
<input id="r1" onclick="check(four or more);" name="r1" type="radio" value="four" /> Four
</form>
I own <label id="Radio1" for="r1">blank</label> chickens.

Adobe Forms - Make Default Text Un-Editable

Aug 9, 2010

First off, sorry if this is the wrong section. Adobe Forms isnt exactly Web Development, but its the only place I could find to post about javascript. If this isnt the correct section, Now, onto the question (please note, I am inexperienced with javascript). I have an Adobe form with a default text like this I have javascript that looks like this, so that when tabbing into the field, it skips past the default text:

function SetEnd (text)
{
if (text.createTextRange)
{
var FieldRange = text.createTextRange();
FieldRange.moveStart('character', text.value.length);
FieldRange.collapse();
FieldRange.select();
}
}
SetEnd(this);

I was wondering if there is a way to make it so the default text cant be changed at all. Even better would be an alternative way of having the default text there but not "part" of the field, but at the same time, not being able to type over it either.

Dynamic Forms And Updating On Reload, Inserting Functions, Jumping Text?

Jan 12, 2010

I'm trying to create a dynamic form, and for the most part it's working out fine.I'm using javascript with onclick and onchange on checkboxes and select boxes to change the form as the user makes selections.However, there's a few issues I'm running into that are giving me problems.

One is that when the user reloads the page, all of the javascript inserted or removed form elements are reset, but the choices on the checkboxes and select boxes aren't, which looks very strange to the user. How can I avoid this? I'm currently including scripts tags in the body of the html, but this is pretty messy and hard to manage. Is there a better way? Second is that I'd like to be able to insert javascript function declarations into text that is dynamically inserted by javascript.However, when I do so, the browser does not recognize the functions. The reason I'd like to do so is that I am using Ruby on Rails, and would like to be able to keep the scripts in the partials to which they relate. I have to use inline javascript, because the scripts are having element ids inserted based on Ruby variables. Is this a lost cause, or is there a technique that enables dynamically inserted javascript to be loaded?

Lastly, my dynamic form's javascript shows or hides portions based on what it encounters while loading. The main reason is that I want to show the whole form for users without javascript, and then hide advanced or obscure details unless they are activated with a checkbox on the form for users with javascript. However, this is creating a jarring pop-in effect, where on first load, the pre-javascript formatted page is shown for a split second, and then the javascript kicks in and fixes everything and the page visibly jumps and changes. Is there a way to avoid this to create a more polished effect?

Create A Small DHTML Code That Created A Unordered List Of Input Forms Dependent On The Number Selected From The Select Dropdown Menu

Oct 21, 2011

I wanted to create a small DHTML code that created a unordered list of input forms dependent on the number selected from the select dropdown menu. Problem is that it doesn't seem to want to generate the list. I think the variables are within the scope of the function too, and I didn't get an errors from the javascript console when using firebug. The script itself runs, I tested it when I used the old standby alert(); to see if the script was active. Here's the code:

Dynamic Resizing Text Display On A Limited Screen Space

Jul 26, 2010

A UI built using HTML and CSS has limited screen space. One of the elements is a div tag (<div id="mtext">) that will contain text of variable length. If the text is > 500 characters, I am displaying it as a link. When the user clicks the link, I want the text to be displayed in a layer above all the rest of the elements in the page. How can this be done using javascript..

Code:

A div element that contains some text of variable length. If the length exceeds say 500 characters, Display it as truncated text. ( like "Example text...") The entire truncated text becomes a link When the user clicks the link the content in the div element "pops out" to fill the screen above other elements on the page Image showing truncated text... (before clicking) Image showing text display after clicking the text...

How To Loop Through Forms?

Jul 23, 2005

Using DOM in IE, how can I loop through FORMs and access FORM elements
in a specific form? For example, www.hotmail.com has about 13 forms.
I believe the one displayed is dependent on the URL. If I want to
access the submit button of the visible form, which is usually the last
one, how is that done?

Currently, I look for type=submit using DOM but it doesn't find
anything and only loops through the first FORM elements.

Two Forms One HTMarriage

Jul 23, 2005

I've been trying to teach myself JavaScript via a book and a number of
JavaScript Tutorials Online. I have more understanding of what I am doing,
although definetly not has much as what I have read on this newsgroup.

I'm trying to learn a new skill in order to hopefully get a job. My job went
to india while I was out on medical leave (carpal tunnel.)

My question, I have two JavaScript / Htm pages identical to the one below.
I'm trying to figure out how I could put both of these "identical"
javascript pages into One HTM page. But I am clueless as to what to look
for and or how to proceed. I'm thinking that I need to somehow add a
checkbox_checker() and a checkbox_checker(2) or something like this.

I've looked at the "For Dummies" book on JavaScript, and my Beginning
JavaScript Book as well as Google'd. Funny thing is though you have to have
enough "knowledge" of JavaScript to know what to look for....
