Checkbox And OnClick

May 15, 2003

I have some code that I want to implement on a page.
I've got a form field (SuppRegFee) that I would like to interact with
using a checkbox. When the user clicks the checkbox, javascript
populates the form field with a dollar amount ($1100). I've got that
part working just great:

PHP Code:

<input type="checkbox" name="Yes" value="Yes" onClick="SuppRegFee.value='$1100'" onUnClick="SuppRegFee.value=''"><br><b>Supplier Registration Fee:</b><br><input name="SuppRegFee" value="" size="5">

However, what I also want is that when the user UNCHECKS the box, the
total vanishes. Javascript offers the onClick method, but there appears
to be no "OnUnClick" method. How might I go about getting this to work
for me?

Checkbox Onclick Submit() Not Working In IE Mac

Jul 20, 2005

I have a set of checkboxes and I would like to submit the form they are when one of them is checked. It works fine in IE, Netscape, and Mozilla on Win2K, also in Mozilla on the Mac, but does not work in IE 5.2 Mac. When you click the checkbox nothing happens.

Am I doing something incorrectly? Here's the code:

<form name="newRevenueBudget" method="POST" action="/budgetsurvey_02/05.do">

....

<input type="checkbox"
name="newRevenueSourceIndexes"
onclick="document.newRevenueBudget.submit(); return false;"

Remove Onclick Event From Checkbox Nested Within H2?

Jul 10, 2010

I have the following javascript for an 'accordian' style html widget.

Code:
var accordionItems = new Array();
function init(id) {
// Grab the accordion items from the page

[Code].....

I have nested checkboxes within each <h2> but I need them to behave independently of the onclick event that is set to the <h2> in the javascript.

In other words, when I select a checkbox, I don't want the onlick event to trigger.

[<input Type="checkbox">] OnSelect Vs. OnClick

Jul 20, 2005

Does the following indeed imply that this event is NOT called when an <input type="checkbox" is toggled?

This would thus imply the usage of the onClick handler instead (assuming an action needs to be invoked on check/ uncheck).

W3C Recomendation:
18 Scripts

onselect = script [CT]
The onselect event occurs when a user selects some text in a text field. This attribute may be used with the INPUT
and TEXTAREA elements.

I *know* the onClick can be used, I am just wondering about the use og onSelect.

Make An Onclick Event Change The Document.onclick ?

Sep 4, 2010

I want to make it so that when I click on something, it changes what document.onclick does.

This is a simplified version of what I'm trying to do:

Code:
<div id="clickme" onclick="document.onclick = function(){ alert ('This should not be alerted on the first click'); }">Click here</div>

However, as you'll notice, the alert box shows up on the first click as well. The only way I have been able to get around this behaviour is to have the first onclick execute a timer that will then set the document.onclick after 1ms, however this seems very messy to me.

OnClick In TR Conflicting With A Onclick

Aug 31, 2007

I have the following sample code and when I click the a href link it pops up both windows.

HTML4Strict Code:
<tr false;" style="cursor:pointer">    <td>Some data</td>    <td>More date</td>    <td><a href="thatlink.html" false;">Details</a></td></tr>

In other words - linking the link that should open up 'thatlink.html' opens up that window first followed by the 'thislink.html' window in the table row onclick call.
