Form - Set The Validation So If One Option Is Selected From A Picklist - Complete A Text Field As Well
Feb 14, 2011
I have a form set up and I need to set the validation so if one option is selected from a picklist, they need to complete a text field as well.
This is the code i'm using:
Code:
Reason is a picklist, I want it to show the alert when option 1 from the picklist is selected and no text is in the Row_Number field.
If any of the other options are selected, I want to make sure the Row_Number field is blank.
As I said, I'm sure this is a very simple thing, but I been working on it for ages, and cannot get it to work, I get the alert every time the Row_Number field is blank.

lets say i have this form:
Code:
<html>
<body>
<form name="x">
<table>
[Code].....
what i want to do is have a selection from 'tst' trigger an input into 'choose' from the data inputted into the 'fname' and 'lname' fields.
for example, i want option '1', when selected to draw the input from 'fname' and place it into 'choose'
or i might want to select the data in 'lname' instead, so i will tie option 2 to it, so when the user selects option 2 the contents of 'lname' go into 'choose' instead.

I have written a form in HTML which contains username,lastname,email,password and submit.I have written a javascript to validate this form [validate(username,lastname,,password)].On submit this javascript function will be called and hence form get validated. I am passing all the arguements(username,lastname,email and password) to the javascript function..Is it possible to make me a code such that it should call an individual function for each field in the form.for ex:if i have not entered username, last name in the form and attempt to submit, only username arguement should be passed to the function as it comes first in the form.In other sense i want to validate individual text field validation of my form.

how to Change a Hidden Fields Name based on selected option. The hidden fields name is sent off and I need to change the name depending on what option they select. For if they select MyList the hidden field name needs to be SelectLists[40] or if they select testlist the hidden field name needs to be SelectLists[41]. This is probably way, way off but I've done this and it doesn't work.
[Code]....

I have a web form with several fields. If I copy & paste from a RTF document into a field, the javascript validation and field length are bypassed and cause the form to fail.

I have an html drop down list. the list has an 'other' option. when the other option is selected I want a text box to pop up to the left of it for entry. I was thinking about using a hidden <div> to contain the text box. and when other is selected to unhide it. How do I unhide it when other is selected?

I’m trying to get the text() of a selected option that has been dynamically built.
I am using the following code in a doc ready fun:
Code javascript:
$('#content_category').change(function(){
var catselect = "";
$('#content_category option:selected').each(function(){
[Code]....
The second select (#content_sub_category) is populated dynamically (PHP) onChange of the #content_category select.
I can get the text() of the #content_category select but nothing for the #content_sub_category select!
I’ve tried to look into rebinding on Jquery’s FAQ page, but can not get it working.

I'm taking a beginning javascript class and have been trying to figure out one last part of a homework assignment and am just not seeing how to work it out. What I'm having trouble with is doing the text verification. When a user selects an option from the select list they then need to type in the text area given. If the user doesn't type the word selected in the list then an error message should appear under the text area. If you look at my code you'll see that I have the text_check() function doing the verification. I can get it to work when there is only one option but once I add the other two it stops working. I've tried if... else and other variations, but can't seem to nail it down.

Here is my options select from my form. Its dynamically generated with php.
Code:
<select id="upgrade[]" name="upgrade[0]" onchange="javascript:calTotal(this);">
<option value="1">1</option><option value="2">2</option>
</select><br />
<select id="upgrade[]" name="upgrade[1]" onchange="javascript:calTotal(this);">
<option value="1">1</option><option value="2">2</option>
</select><br />
<select id="upgrade[]" name="upgrade[2]" onchange="javascript:calTotal(this);">
<option value="1">1</option><option value="2">2</option>
</select><br />
Using javascript I want to get the selected value. Here is what I have, but its getting no where:
Code:
function calTotal(aVar)
{
var c = document.getElementsByName(aVar);
c = c.length ? c : [c];
for(var i=0; i<c.length; ++i)
{
if(c[i].value==1)//I am getting undefined here
{
}
}
Is there a way to loop through an array of option selected like the one I have here?

I have the following dropdown list box [code]...
I want to show() a textbox and a label based on someone selecting the "is between" option of the dropdown list.
I have multiples of these dropdowns and all of them will have to do the same thing. In other words I have
DDLConditional1 2 3 4... infinite. I've already been able to make the button work that appends new conditionals.

The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
function validate_form ( )
{
valid = true;
[code]....

I am having a problem with a simple javascript validation routine for a drop-down list, which works fine when there is only one form on the web page, but breaks when another form is added. I am new to javascript, so I expect this is a simple error in syntax.

I am trying to display a rel of each option as they are selected into a div below it . There are several selects of classProductAvailability on the page. When one of the selects changes, I'd like the value of the rel of the selected option to display.At first it seems to work, but only if you start by changing the last pull down menu. The trouble seems to be in the"select.ProductAvailability option:selected", this needs to be written for this instance, not all of the selects of that class on the page. How do I write that, I've tried$(this+" option:selected") but it won't take.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
