Validate Textbox After Checkbox Clicked
Oct 31, 2011
I very new to JavaScript and I need to validate a text field after a checkbox has been clicked. This is part of a larger form validation. I am looking for the simplest and easy solution to this issue. I have seen a couple of other examples that are far too complicated for the my needs. The form is asking a user to identify a referral source. If the referral source is a website, it wants the user to provide a URL. To clarify, all it needs to do is verify that if the website checkbox is clicked then there is text in the corresponding textbox. Here's what i'am been trying to make work

I have a textbox and 2 checkbox, and I'd like to validate the textbox if at least one of the two checkbox is selected. If is just one checkbox, I'll write:
myTextboxl: {
required: '#myFirstCheckbox:checked'
}
but in the case of 2 checkbox, how can I solve?

I have a simple form which I am running a validation on a single text box (as shown below, adapted from the milk example).
$(document).ready(function() {
// validate signup form on keyup and submit
var validator = $("#updateModules").validate({
rules: {
guestbookContact: {
required: true,
email: true
},
},
// the errorPlacement has to take the table layout into account
errorPlacement: function(error, element) {
if ( element.is(":radio") )
error.appendTo( element.parent().next().next() );
else if ( element.is(":checkbox") )
error.appendTo ( element.next() );
else
error.appendTo( element.parent().next() );
},
// specifying a submitHandler prevents the default submit, good for the demo
submitHandler: function() {
form.submit();
},
// set this class to error-labels to indicate valid fields
success: function(label) {
// set as text for IE
label.html(" ").addClass("checked");
}});
Now I only want to validate the text box if the checkbox "requireEmail" is checked. Is there an easy way to do this?

I would like to get the id of a html check box when the client clicks it. I want to do this on the client side so i need to use java script. I want to be able to do this in both fire fox and ie window.event.srcElement works great for ie but not for firefox do not tell me to use Event.target for firefox because that does not work. At least it is not working for me anyway.

Can a checkbox do 2 different things after it is clicked? Right now I am using this...
<input type="checkbox" onclick="processCheckbox(this);">
<input type="checkbox" onclick="activLink(this.checked)">
I don't want to have 2 checkboxes on my page, just 1 and get the same result.

I have a form with 2 radio buttons (ACCEPT/REJECT). When the page is initially loaded, no textbox should be visible.
When a user clicks the REJECT radio button, a textbox should automatically appear below the radiobutton where the user can motivate why he chose the reject option (which we require).
When the user clicks the ACCEPT radio button, the textbox should not appear because we don't need motivations for accept actions.
Does someone have a clue if and how I can realize this in JavaScript?

I just got a checkbox form to validate, but the name of the checkbox group is a variable from PHP. so I have to pass the name of the checkbox in the parameter like function checkForm(inputName). The browser said it is a null object(inputName), anybody helps? Easy for you guys here, so just give me a hint.

I have a form with two buttons: "Delete" and "View". A checkbox is required for all actions. Validation happens when a button is clicked. If it's "View", it is just a normal operation.
However, if it's "Delete", if the form is valid, it then needs to show a confirmation before form submission via custom handler (submitHandler). submitHandler: function(form) { if (confirmDelete()) { form.submit (); } }
Problem: How do I know if the button is Edit or Delete inside submitHandler? The function above open the dialog even for "View" button.

I have put the following code into a sharepoint aspx page. So that when I change the value in a drop down box it runs a function (in this case it displays "Works").
<script language="javascript" type="text/javascript">
function getField(fieldType,fieldTitle) {
var docTags = document.getElementsByTagName(fieldType);
for (var i=0; i < docTags.length; i++) {
if (docTags[i].title == fieldTitle) {
return docTags[i]
}}}
function TestFunctionName() {
alert("Works");
}
getField('Select','DropDownBoxName').onchange = function() {TestFunctionName()};
</script>
What I'd like to be able to do as well is when a check box is changed or clicked on the same thing happens. I dont seem to be able to achieve it though. I've change the line...
getField('Select','DropDownBoxName').onchange = function() {TestFunctionName()};
to...
getField('Input','CheckBoxName').onchange = function() {TestFunctionName()};
and
getField('Input','CheckBoxName').onclick = function() {TestFunctionName()};

After a bit of looking around I thought I has done it, but no luck. Can anyone let me know whats going on here? Code:
