Retrieve And Pass Information To And From HTML Forms
Jan 7, 2009This question may appear opposite of most, but I'm learning JS using a book and I can't understand why/how this particular code works. I'm working on simply retrieving and passing information to and from html forms. This is a very simple script that will change what is selected in the drop down box depending on a button push.
Here is the script:
Code:
function flip(pizzatype) {
if (pizzatype.value == "Veggie Special") {
document.forms["pizzaform"].topping.value = "veggies";
} else if (pizzatype.value == "Meat Special") {
document.forms["pizzaform"].topping.value = "meat";
} else if (pizzatype.value == "Hawaiian") {
document.forms["pizzaform"].topping.value = "hampineapple";
}}
And here is the form's html:
Code:
<form id="pizzaform" action="#" onsubmit="return false;">
<p>
<input type="button" name="veggiespecial" onclick="flip(veggiespecial)"
value="Veggie Special"/>
<input type="button" onclick="flip(meatspecial)" name="meatspecial"
value="Meat Special" />
<input type="button" onclick="flip(hawaiian)" name="hawaiian"
value="Hawaiian" />
</p>
<p>Main Topping: <select name="topping">
<option value="cheese" selected="selected">Cheese</option>
<option value="veggies">Veggies</option>
<option value="meat">Meat</option>
<option value="hampineapple">Ham & Pineapples</option>
</select></p>
</form>
The way I see it is the button onclick will call the flip function and pass it a var, for example "veggiespecial". I understand the code that will perform the actual change on the drop down menu. What I don't understand is the if statement.
if(pizzatype.value == "veggiespecial")...
Shouldn't it be just (pizzatype == "veggiespecial")?
Why does it have to be pizzatype.value? Where the heck does the .value come from???
Retrieve Specific Values In A Element In XML DOM
Nov 5, 2004var oxml = document.getElementById("xmlfile");
var oDom = oxml.XMLDocument;
var xy=oDom.getElementsByTagName("Name");
I was able to produce the below XML:
<root>
<Name Id="174" userid="A2 " level="1" selected="1"/>
<Name Id="175" userid="A5 " level="1" selected="1"/>
<Name Id="183" userid="A9 " level="1" selected="0"/>
<Name Id="110" userid="B1 " level="1" selected="0"/>
<Name Id="116" userid="B16" level="2" selected="0"/>
<Name Id="109" userid="B25" level="2" selected="0"/>
<Name Id="120" userid="C29" level="1" selected="0"/>
<Name Id="133" userid="D03" level="1" selected="0"/>
<Name Id="132" userid="D3 " level="1" selected="0"/>
</root>
What code do I need to write to traverse above XML code to retrieve those userid value only when the selected=1???? And display the userid "A2" and "A5" with window.confirm in Javascript

Getting Input Values From Forms?
Mar 9, 2011I'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];

Forms - Adding Values And Searching A Directory Dynamically
Aug 28, 2009I 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.
Copying Input Array Element Values Between Two Forms?
Nov 3, 2009I 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.
Write Forms Values To External File, Then Execute A Program?
Sep 23, 2006I'm trying to develop fast, simple, html-based front ends
for some Windows application programs. My idea:
1. Use html forms to let users supply run parameters (title,
run options, etc.)
2. When the user presses a submit button:
a. The selected options for all the form fields are
written to an external file (e.g., c:projectinput.txt)
b. The application program, say, prog.exe, is executed.
This program then reads the run parameters from the file
input.txt and proceeds. Code:

Firefox Autofill Plugin - Choose Random Values For Forms
May 6, 2010I'm using the autofill forms plugin for firefox which can be found here: [URL]. I use it to automatically fill various web forms. But I would like certain values to be chosen randomly from a list I create. I contacted the developer and he said the add on probably does not need a new feature because there is a 'dynamic tags' function to fill certain forms with dynamic values (e.g. the current time or date). He has given over the project to another developer and told me I probably would find a solution in a good javascript programming forum.
Basically, I just need a javascript code which chooses on item from an array randomly, I guess? Here are sample dynamic tags from the plugin:
<datetime> new Date().toLocaleString()
<useragent> navigator.userAgent
<langcode> navigator.language
<resolution> screen.width+'x'+screen.height
<clipboard> this.getClipboardText()

View 2 Replies View RelatedAdding Forms But It's Limited To Text Input Forms?
Nov 14, 2011how 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.
JS To Retrieve Data From DB?
Mar 2, 2006We are trying to develop an Engineering application using PHP,
Javascript with Informix as the back-end.
Is it possible to retrieve data using Javascript but by accessing the
Database. Say somebody enters part_no, than using Javascript is it
possible to connect to the part master and retrieve the division and
desc information?
I am not allowed to use the PHP because this will require the user to
insert the part number on the first page (user input page) and then
retrieve the information using PHP and display the info on the second
page (processing page).
I will need this to be done on the same page. That means the info will
need to be retrieved instantly (on the fly).
I think of building a javascript array for the part master table using
PHP but finally decided not to as the table is a huge table (contains
more than 1000000 records).

JQuery :: Checking Multiple Input Values Against Various Other Hidden Minimum Values
Jul 19, 2011I have a list of products where they have minimum quantities in a hidden input. Some products have multiple colours, though the same minimum quantity and I'm trying to implement a jQuery check that entries made are at least equal to the minimum.
Blank or '0' entries are fine but if it's below the minimum quantity it should set to the minimum.

Is there something obviously wrong with this? It isn't performing the minimum check and I'm really not sure why.
Ajax ::Submit Inputs Values Using Normal Button / How To Keep And Clear Values
Apr 15, 2010In part of my form, I have 3 inputs (one textarea and two text inputs),I am validating their value format using AJAX (each input triggers error message on its label in case format is wrong). Also I have one button, "NOT submit button" (type = button).Now, when clicking on the button it must enter the value of those three inputs in my database in case they are true then all inputs values must be cleared. In case AJAX validation is wrong and in case the user clicked on that button, the value of fields must kept as it is.
Actually I can not use submit button because I have it for the whole form and what I am taking about is a part of the form and it's not possible to make nested forms as I know it violates html rules. It's easy to make it if I am taking about submitting button as I can view session values on fields after submission in case ajax returns error.I can clear inputs from Javascript, but it will be cleared on both cases if AJAX validation true or wrong. Each input field has AJAX Error message that will be triggered when the input format is wrong.
