Select All Checkboxes From Array?
Mar 12, 2008
I need to be able to get all my checkboxes which are in an array and which have the name:
name="personselected[]"
to be all checked when a button or link is clicked.
I have looked around and can only find examples of where the checkboxes are not in arrays. The closet I have found to what I need is below but it won't work due to my checkboxes being an array.
Code:
function checkAll(field) {
for (i = 0; i < field.length; i++)
field[i].checked = true;
[Code].....

I have the following checkbox code:
echo "<input name="picbigid[]" type="checkbox" value="$pic[src_big]">";
I then want to select all the checkboxes so I have this code:
[Code]..
It works but I can't have it like that because the form posts to another PHP page that needs the input name as an array.

I've seen a variety of implementations around that enable selecting all or no checkboxes by using a checkbox to toggle that choice. However, I'm trying to find a way like this: I have two text links on my page: Select All, and Select None. How can I get those links to call a jquery function to select all or select no checkboxes in my form? As a little food for thought:
<head>
$(function() {
//function for selecting all or none...is there a way to make a single function that passes in a parameter to differentiate between selecting all or selecting none, or do I need a separate function for both?[code]....

I have the HTML all laid out for what I'm trying to do. I want to have the user be able to select any 10 checkboxes, and keep a tally of how many are selected, and how many are left to go. Should I do this with jQuery?
Code HTML4Strict:
Select any 10 cds for $20<br />
You have chosen $selected CD's<br />
You have $remaining CD's left</p>
[Code].....

What am I doing wrong here? Forgive me if it's blindingly obvious, but I can't get this to work:
HTML Code:
<html>
<head>
<title>test</title>
<script type='text/javascript'>
function editPhotos(numPhotos) {
for(var i = 0; i < numPhotos; i++) {
if(document.forms.boxOrder.photos[i].checked == true) {
alert('yes');
} else {
alert('no');
}
}
}
</script>
</head>
<body>
<form name='boxOrder'>
<input type='checkbox' name='photos[0]' /><br />
<input type='checkbox' name='photos[1]' /><br />
<input type='checkbox' name='photos[2]' /><br />
<input type='checkbox' name='photos[3]' /><br />
<input type='checkbox' name='photos[4]' /><br />
<input type='button' name='edit' value='Edit Selected'
onClick='javascript:editPhotos(5);' />
</form>
</body>
</html>

In my HTML, I have several of the following:
<input type='checkbox' name='right[]' id='right[]' value=Ɔ' />
All are the same except the value is set differently for each one. The
reason for the [] is so I can access the checkbox values as an array on
the processing page (when clicking 'Submit');
However, I want my Javascript code to examine these objects first. My
onclick event handler function (below) is called (I get the 'hi there'
popup), but it does nothing afterward (i.e., neither 'checkbox' alert
appears, and the handler, strangely, seems to return 'true').
I suppose my problem is that I am not specifying the checkbox array
properly. I tried several variations, but I've been working on this
problem alone for several hours and am getting nowhere. Code:

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.

I have js on a form page for users to be able to select all check boxes for classes to enter in a dogs show but I want to be able to offer the facility to select just classes on specific days as well and I don't know how to do it.The form source code for each class to select looks like this:
<input type="hidden" name="day_id_normal[12]" value="5" />
<input type="hidden" name="day_id[12]" value="5" />
<input type="checkbox" name="class_number[]" id="gradeclass" value="12" />

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?

Long story short, I need a button that when clicked selects all of my check boxes. The entire form is check boxes.
The catch is that they all have different names, and altering them isn't an option at this point (too much other code depends on it).
Example:
Code:
<form name="myForm" action="processing.php" method="post">
<input type="checkbox" name="arandomname" />
<input type="checkbox" name="adifferentname" />
<input type="checkbox" name="unrelatednamehere" />
[Code]....
Also, I was hoping to find a way to make the "check all" button become the "uncheck all" button if all things are already checked (and vice versa), but I won't push my luck.
I wasn't sure if this should be considered Javascript or HTML since I'm not really sure where the solution lies.

I have two different rows of checkboxes. When I do an onclick function I only wish to check one column of checkboxes. Not all of them. The one I wish to edit has Id's of "CBOX01, CBOX02, CBOX03 etc, etc. How can I tell my onclick function to only check the ones with the Id's of "CBOX". I cant get the syntax structure correct.
Here is my code example
$("#CntrHistory").click(function(){
var size = $("input:checkbox[]:checked").size();
if (size == "0") {
alert("One Checkbox Must Be Selected.");
return "false";
} if (size != "1") {
alert("Only One Checkbox Can Be Selected At A Time.");
return "false";
} $("input:checkbox:checked").each(function() {
var str = $(this).val();
var substr = str.split("!");
var comp = substr[0];
var ordr = substr[1];
var eqpt = substr[2];

I currently have a form that the checkboxes are automatically populated. There is over 1000 checkboxes in total, 48 of these checkboxes are designed as main topics, when the checkbox for one of these 48 are ticked, it checks all sub catergory checkboxes as well as populates a <select><option> multiple list with its value. When unchecking one of the 48, it unchecks all its sub categories and removes them from the <select><option> multiple list.
The problem I am having is, when i select one of the 48, which populates the multiple list option and checks all sub categories... i go to uncheck one in the sub categories, which successfully unchecks the main category (as it indicates they are not all selected). It also successfully removes the sub category from the multiple select option list and its main category (which became unchecked).
When I go back to check the main category which makes all the sub categories checked... it re-populates the <select><option> multiple list with the values creating duplicates. I need a proper way of when I check a box, it scans the multiple <select><option> list to see if it already exists, then adds it again if it is not there. I have tried the following jquery:
$('#elemSelect option[value = thisCheckbox.value]').length > 0)
but it seems the length always comes out 0 (zero). I need a fast and efficient way of doing this there is over a 1000 checkboxes that can be checked and need to populate this list.

This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.

I have a working example of jQuery validate working in the link below. The newsletter checkbox is required and working. However, the "colors" checkboxes are all named as an array ( ex: name="color[]" ), and so the problem lies in the validation code, where it uses the name of the element to require elements ( ex: newsletter: "required" ).
Code JavaScript:
<script>
$("#testform").validate({

This is for a test, am not sure what they mean by "do not hard-code the resulting quarter years in the javascript":
instructions: When a user selects a date from the investment cycle drop-down box, the subsequent investment values must display the next three fiscal quarters.
E.g:
Do not hard-code the resulting quarter years in the javascript. (empahsis mine...;-)
The subsequent quarters should be presented with checkboxes which are all unchecked.
Checkboxes in markup:
The values to populate the checkboxes (value and label) have to be hardcoded somewhere, no? what am I missing?
