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?
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.
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.

What's wrong with my code?
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?
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)?
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];

When in IE7 or IE6, I can't get a input value with same id. My sample code looks like this:

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.
I'm wanting to make a search function in a limited way.
The following code sends the input text to a page where the script processes it, no problem
Code:
I would like to have text automatically added to the input.
Example: I have a site I want to be only about things that are red.
Someone inputs "table" and the text "red+table" is sent to the search page.
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?

Is this a bug or an intended refactor to be more standards compliant?
FYI - this is the selector I now have to use: $('input:text,input:not([type])')
I have a form element that looks like this:
<input type="text" onchange=doSomething(this)>
and a function:
function doSomething(theField){
}
I know that within the function I can access properties of the field (e.g. theField.name and theField.value). But how do I access theField's index number in the form's elements[] array -- from the "this" reference that was passed to the function? I.E. if this field is elements[3], how can I get at that 3?
Is this possible with JQuery? I have the following code which I think Should do this, but it's not working :/These are two different functions which I've been testing, and the html element is supposed to create a dropdown list via some PHP which will have the option "Other" within it. Unfortunately, I have no idea exactly how to turn "Other" into a text box when the user clicks, and I've been spending a lot of time on this already.

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:

How I'm can learn a name of an element <input>?
I'm attempting to place an img element after an input tag (which has an id).
var loadingImg = document.createElement('img');
loadingImg.setAttribute('id', 'workimg');
loadingImg.src = '/new/images/working.gif'
document.getElementById('username').appendChild(loadingImg);
Basically it's temporary feedback to tell the user that their request is "working". I'm not quite sure how to place the image element after the username element however. Ideas?
I've got a default value of some text in an input element when a page loads.
What I'd like to do is have the value disappear when the user clicks in the
input field.
I've figured out I can use:
onclick="this.value=''"
This works fine, however if for some reason the user adds his own input,
then click somewhere else/clicks back, the text has once again been erased.
So I thought of a function like the following, however it does not work:
function removeinput(x) {
if (x == 'Enter items not on standard list here...') {
x = ''
}
}
onclick="removeinput(this.value);"
I've also tried placing this.value inside of single quotes to no avail.
In a project repeated blocks are identified by an <input type="hidden" value="x" /> field. To get an access to one of the block I wanted first access to that field. My first problem is there and I will explain it by a micro-project (tested with Firefox only)
Here is the HTML code :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=utf8" />
<meta http-equiv="Content-Style-Type" content="text/css" />
<meta http-equiv="Content-Script-Type" content="text/javascript" />
<link rel="stylesheet" href = "index.css" type="text/css" />
<script type="text/javascript" src='Library/jquery-1.4.js'></script>
<script type="text/javascript" src='index.js'></script> .....
And here the javascript code wher is the JQuery question
//meta http-equiv content-type charset=utf8
function test(){
var $id = $('#curUnion').val();
var $objet = $('#toutesUnions > .pseudoFieldset').find('input[value=$id]');
var $test = $objet.val();
var $objet2 = $('#toutesUnions > .pseudoFieldset').find('input[value="1"]'); .....
With $id = "1" as shown by the Javascript debugger (in Firefox) where is the difference between find('input[value=$id]') and find('input[value="1"]')
Giving the alert result => undefined / 1
If you want to test the micro project you will find it in the Test.zip joined. How to access the immediate parent pseudoFieldset to get its html code?
I have a table with several columns containing input elements populated from a database, e.g.,
On every row, I need to perform a calculation using the value of several input fields. So I tried to access the value of the first input field like so (which had worked in another function):
But for some reason it's returning a 0, and the line below also doesn't work:
But this returns the correct class, so I know it's finding the element:
And if I assign the input element an id, say "count," this works:
Obviously I don't want to fuss with individual id's to get the values. How to understand why the first two examples don't work, and how to fix them?
I have a page with an iframe where I've placed few images. I want to create onMouseClick event which will put clicked image's url into Input Text element in parent frame (main page frame) and at the same time it will put image itself into some <div> or <img src> element (if possible) or maybe in some other small iframe, created for this image.
Is that possible to do using JavaScript (with function)? If yes, how can I do that?
I'm using Javascript to create some dynamic content on my website. Basically it's looping through some values and updating an input field with the values.
What I'm wondering is, do I have to do this using a form and an input field? Is there a way I can get Javascript to update the content inside a DIV for example?
I cannot get an appendChild(img) in the following code snippet to work in IE. However, the same script works without any problems in Firefox and Netscape 7.0 The error that is produced in IE is invalid argument. I have used a try/catch block in expectation of producing a better error message however the error message that is received is [objectError].
var pageDiv = window.parent.fraTop.document.getElementById('pageTitle');
if(pageDiv!=null)
{
while(pageDiv.hasChildNodes())
{
pageDiv.removeChild(pageDiv.firstChild);
}
var img = document.createElement('img');
img.src='/wp2f/images/please_wait.gif'
pageDiv.appendChild(img);
}
I have this body:
<body>
<div id="d1">content</div>
<!--I want to append a div right here-->
<div id="d3">content</div>
</body>
I have this javascript code which would add a div after div id="d3":
var adiv = document.createElement("div");
document.body.appendChild(adiv);
How could I modify my javascript code so that instead of adding to the end, making it the last tag, it would be the second tag?
I'm attempting to submit a form via a function which dynamically creates a
hidden input:
function submitLocation(theForm) {
var e = document.createElement('input');
e.setAttribute('type', 'hidden');
e.setAttribute('name', 'location');
e.setAttribute('value', Ƈ');
var f = document.getElementById(theForm);
f.appendChild(e);
document.forms[theForm].submit();
}
The function is called from an anchor's onclick event:
<form name='form1' method='post' action='action.php'>
<a onclick="submitLocation('form1');">Submit</a>
</form>
However the function produces an input which is missing the name element:
<INPUT type=hidden value=1>
The desired output should be:
<INPUT type=hidden name=location value=1>
