Is it possible to use Javascript to uncheck all checkboxes that appear within a specific div?I'm already using names/ids for each checkbox, and these are generated dynamically, so I cant really apply a group to all the checkboxes I want to untick.

I want to check all of my checkboxes in my form that have an id that begins with 'chkEvent'.
<script language="Javascript" type="text/javascript">
$(document).ready(function() {
$("#toggleEvents").click(function(event){
$('input[@type=checkbox]').each( function() {

someone here might know what I'm doing wrong. I have a list of checkboxes, in multiple rows with each along the lines of:

I have a simple script that counts the number of check boxes that are checked and then when reaches a certain number displays an alert. It is triggered by the onclick event.My question is, by keeping with the onclick event how do I make JS run something different when a box is unchecked.So bottom line - if it is checked the counter goes up...if it is unchecked the counter goes down all being triggered by the onclick event - is this possible.
View 8 Replies View RelatedI'm trying to write some code that uses buttons to check and uncheck certain checkboxes. I am stumped and all the code I have been finding is using for loops to check or uncheck all the boxes, when I just want to check or uncheck certain ones. Here's an example of the type of function I'm trying to use:
function checkSome (form) {
document.myForm.list.one.checked = true;
document.myForm.list.two.checked = true;
document.myForm.list.three.checked = false;
}
And the button:
<input type="button" value="Option 1" onClick="checkSome(this.form)"/>
I have a pretty simple survey form, with 5 checkbox answers, one of them being "None of the Above". All 5 are part of the same question1[] array. My goal is to have a function that unchecks the other 4 boxes when None of the Above is checked. The problem is that since None of the Above is part of the question1 array, it unchecks itself. So how do I separate this None of the Above option? After all, it is still a valid answer to question 1, so I don't want it to sit in a different array just because...
Here's what I have now:
Java:
function SetValues(Form, CheckBox, Value){
var objCheckBoxes = document.forms[Form].elements[CheckBox];
var countCheckBoxes = objCheckBoxes.length;
for(var i = 0; i < countCheckBoxes; i++)
objCheckBoxes[i].checked = Value;
}
HTML:
<input id="question1" name="question1[]" type="checkbox" value="Answer 1"> 1<br>
<input id="question1" name="question1[]" type="checkbox" value="Answer 2"> 2<br>
<input id="question1" name="question1[]" type="checkbox" value="Answer 3"> 3<br>
<input id="question1" name="question1[]" type="checkbox" value="Answer 4"> 4<br>
<input id="question1" name="question1[]" type="checkbox" value="None of the above" onclick="SetValues('form1', 'question1[]', false);"> None of the above <br>
So again the issue with this code is that since None of the Above is inside the question1 array, it unchecks itself as well.

View 1 Replies View RelatedI have checked over my code several times and cannot find what I've done wrong with my first script, which is to check/uncheck all checkboxes in a html form. Nothing is checking or unchecking, and I am seeing the "Error on this page" in IE whenever i first click one of the two buttons. Here are the steps I have taken1. I have imported the jQuery library which I have just downloaded (1.4.2 development version, 155kb) with the following code:
< script
type
= "text/javascript"

So that I can pass multiple checkbox values to my PHP processing script as an array I added the square brackets to my form's checkbox input element's name, like this: <input type="checkbox" name="checkGroup[]" value="'.$rowIDs.'" /> Because it has to match, I updated the input element I use to check/uncheck all the checkboxes so that it now looks like this: <input type="checkbox" name="all" onClick="checkAll(document.ResIDsDates.checkGroup[],this)" />
When I manually select multiple checkboxes I can successfully pass any number of checkbox values through
the POST array to my process script...but my Check/Uncheck All box has ceased working -- adding the
square brackets to the checkbox input's name disabled it.
I tried playing with the ASCII equivalents to the brackets, but no go. Is there a way to retain the array
functionality and pass multiple checkbox values to the script AND enable the Check/Uncheck All box?
I have the following checkboxes:
[ ] None [ ] Option 1 [ ] Option 2 [ ] Option 3
When the first checkbox is checked (None), I need the other three checkboxes to:
1. Become unchecked if the user had checked them
2. Become disabled
If/when the first checkbox is unchecked after that, the other three checkboxes would become enabled.
I have a page that has groups of checkboxes that are generated dynamically. The identifiers for all the text boxes are generated dynamically so i dont know what the name will be for any of the checkboxes before the page has loaded.Each group of checkboxes has a master checkbox and several child checkboxes. Each master checkbox has a unique ID. All child checkboxes have a 'class' element which is the ID of its master checkbox. I want to use the ID of the master checkbox to determine which checkboxes to check/uncheck. When the master checkbox is clicked, i want all its associated children (i.e where child.class=master.id) to be checked or unchecked. Here is an example of what i have so far

I am trying to allow a user to easily uncheck/check all checkboxes in a form by checking or unchecking a checkbox. The checkboxes would be in a form like so:
<form action="" method="post">
<input type="checkbox" name="checked[]" value="1">
<input type="checkbox" name="checked[]" value="2">
<input type="checkbox" name="checked[]" value="3">
<input type="checkbox" name="checked[]" value="4">
</form>
I use an event handler to call a function:
<input type="checkbox" name="checkall" onchange="checkall('checked[]', this.checked)">
And here is the function:
function checkall(box_name, current_state) {
all = document.getElementsByName(box_name);
action = (current_state == "checked") ? "false" : "true";
for (i = 0; i < all.length; i++) {
all[i].checked=action;
}}
The event handler should pass the name of the checkboxes and whether the "check all" checkbox is currently checked or not to the checkall() function. Nothing happens when I check/uncheck the "check all" function.
How does one uncheck a check Box with Javacript when the rows of the Table are dynamically created byPhp so we do not know what the row numbers are going to be before hand.That is we have these 2 check boxes:
<input type="checkbox" name="approve[]" value="<?php echo $user_id; ?>" checked onClick="uncheck(reject, <?php echo ($row - 1); ?>>
&
<input type="checkbox" name="reject[]" value="<?php echo $user_id; ?>" onClick="uncheck(approve, <?php echo ($row - 1); ?>">
So if they click on check box "reject", we then want check box "approve" unchecked and vis-versa.FYI, I was using this Javascript code:
function uncheck(field, i)
{
field[i].checked = false ;
}
But the combination of above is not working!
I'd like the ability to have a checkbox that will check all elements with a certain name when selected, and to have another checkbox that will do the same with another set of elements.
I had found the following code, and it worked:
function toggleChecked(oElement)
{
oForm = oElement.form;
oElement = oForm.elements[oElement.name];
if(oElement.length)
{
bChecked = oElement[0].checked;
for(i = 1; i < oElement.length; i++)
oElement[i].checked = bChecked;
}
}
function toggleController(oElement)
{
oForm=oElement.form;oElement=oForm.elements[oElement.name];
if(oElement.length)
{
bChecked=true;nChecked=0;for(i=1;i<oElement.length;i++)
if(oElement[i].checked)
nChecked++;
if(nChecked<oElement.length-1)
bChecked=false;
oElement[0].checked=bChecked;
}
}
I was able to the use the following HTML for my check/uncheck checkboxes:
<input type="checkbox" name="addsuggestedjokes[]" onclick="toggleChecked(this)" />
<input type="checkbox" name="removesuggestedjokes[]" onclick="toggleChecked(this)" />
And the following for my other checkboxes:
<input type="checkbox" name="addsuggestedjoke[]" value="<?php print $jokeid ?>" onclick="toggleController(this)" />
<input type="checkbox" name="removesuggestedjoke[]" value="<?php print $jokeid ?>" onclick="toggleController(this)" />
However, this presented a problem because I do not want my check/uncheck checkboxes to be part of my addsuggestedjoke[] or removesuggestedjoke[] arrays!
I tried to change everything as follows, but it doesn't work:
Changed toggleChecked:
function toggleChecked(oElement, elementName)
{
oForm = oElement.form;
oElement = oForm.elements[elementName];
if(oElement.length)
{
bChecked = oElement[0].checked;
for(i = 1; i < oElement.length; i++)
oElement[i].checked = bChecked;
}
}
Changed check/uncheck HTML:
<input type="checkbox" name="addallsuggestedjokes" onclick="toggleChecked(this, 'addsuggestedjoke[]')" />
<input type="checkbox" name="removeallsuggestedjokes" onclick="toggleChecked(this, 'removesuggestedjoke[]')" />
How can I make this work?

What is happening is $(this) is no longer based on .expand being the (this) that is clicked.
like if i have a button SOMEWHERE randomly on the page with this
<div onclick="Minimize('_alerts');">Click Here</div> this will minimize alerts but because the (this) in minimize function doesn't actually point to the right button that I want to add a class to.
Is there a way to modify the minimize function so that it finds the <div id="mytoggle"><ul> <li class="expand boxminimize" rel="_alerts"> using the rel toggle, and then changes the class of the li from expand boxminimize to boxexpanded??
just like the .expand click function I posted on the top of the post that works?
Another thing that has been driving me crazy is that css positioning is handled differently by different browsers. JS is not my area, but I can do a lot with CSS, and I do, but cross browser compatibility is killing me.
I can use an IF IE statement and only IE runs that segment of code, but I haven't been able to figure out out how to make ONLY firefox or ONLY opera or safari enact an encapsulated segment of code. The same type of IF statement doesn't work for them.
Is there a single method using JS that works for all browsers?
how to uncheck the check box , when i check another check box, for example having 4 check boxes, be default check box is checked ,. when i check the check box 2 , then need to uncheck the checked one, How to do this in jquery ,

I know this code works just fine:
function result(){
var result = document.getElementById('resss').innerHTML;
}
But what I actually want is to import data from a table of an external website. E.g. I want to get the innerHTML of a specific cell in column 3 and row 2 of a specific site.
I've a problem when I'm trying to check and uncheck a checkbox. It work great when doing everythingprogrammatic, but when I check or uncheck using the mouse and then try to check or uncheck using the code doesn't work anymore.I tried with both ways:
$('#myCheck').attr('checked', true); // to check
$('#myCheck').attr('checked', false); // to uncheck
and:

I have an issue that is specific to IE (testing in IE8).
The following code unchecks checked checkboxes in FF, but will simply not work in IE :
$j("input:checkbox[checked=true]").each(function() {
$j(this).removeAttr("checked");
//$j(this).attr("checked",false); this doesn't work either
//$j(this).attr("checked",""); this doesn't work either
alert($j(this).attr("title") + " is "+$j(this).attr("checked"));
});
In all cases the expected alerts are firing, and the alert says that the checkbox is not checked.
But the checkboxes are not unchecked and subsequently still fire when the form is submitted.
I have the following page [url] and I would like to add a button or checkbox to check/uncheck all. Note we are already using some javascript for custom checkboxes so it needs to integrate with that.

Is there a way to do a check/uncheck all on a list of checkboxes that have different names/IDs? Like this:
HTML Code:
<input type="checkbox" name="checkbox1" id="checkbox1" value="All" onClick="checkAll(document.form.checkbox,this)">All Checkboxes
<input type="checkbox" name="checkbox2" id="checkbox2" value="First"> First Checkbox
<input type="checkbox" name="checkbox3" id="checkbox3" value="Second">Second Checkbox
Below is the JS code I've used in the past (when my checkbox names/IDs are the same throughout)
Code:
function checkAll(checkname, exby){
for (i = 0; i<checkname.length; i++)
checkname[i].checked = exby.checked? true:false;
}
How to copy some text to the clipboard with jquery or javascript, from google. I know there is a plugin named zeroclipboard [URL] can do this with cross browsers. When I tested it on my site. I set it to copy text optionally. It can't work. My test link is [URL]. It always copys all the values. Even I uncheck some check box. May be the value doesn't be changed. But when I alter() the variable, the value is ok. how to correct it? I want it can copy the checked box value. If the box unchecked, then don't copy its value.
View 3 Replies View RelatedI have the three embedded Ruby(erb) check_boxes below:

Patient #2<%= check_box("patient", ƈ', {}, "yes","no") %></br>
Patient #4<%= check_box("patient", Ɗ', {}, "yes","no") %></br>

I want to create a button(s) to check all/uncheck all the check_boxes
if clicked by the user. I was thinking I had to use javascript to do
this, but the erb is appending the value to the name in the HTML
output. What this does is prevent my javascript from recognizing these
check_boxes as a collection named "patient".
I know this isn't a pure javascript question, but I am at a loss. I am
new to both languages, which doesn't help either.
