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.
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'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; }
I 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:
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 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.
A web page I'm creating will allow a visitor to download a number of PDF files. A form on the page has one checkbox for each of the PDF files. I also wanted to add a checkbox to select/deselect all the PDFs.All works fine, but I also want the visitor to supply their name and email address before downloading, so I want to add another checkbox before the submit button to allow them to opt in/out of having their email address used for further mail shots.Unfortunately since the code selects/deselects all checkboxes on the form, it also ticks/unticks the opt in/out checkbox.
Is there a way - possibly by targeting the opt in/out checkbox's ID - to filter it out of this mass selection/de-selection process?I'm sure it's pretty straightforward but as I say I'm a Javascript novice.
I am creating a form using a system called SORCE.The load an article page, only check boxes.I have three checkboxes and want to disable the other 2 when one of them is checked. I have ability to enter javascript code behind each checkbox and there is already some code behind each check box. Below is an example of the code behind the first check box:
Quote: function do_value_toggle_54740(oCurObj) { oForm=oCurObj.form[code].....
I have tried adding the other checkboxes to the if statement, but this just causes errors on the form.The 2nd check box is called value_toggle_54743 and the third is calledval_toggle _54746.What javascript can i add behind each check box to disable the other two when one is clicked?
I am unable to work my Jquery code for checking all the checkboxes which is inserted in a GridView User control. However,The same code works perfectly fine when I change the user control to a web form.ie,from .ascx to .aspx.[code]This code works perfectly if i change from a user control back to web form
Just wondering if anybody went through this before. The following code works fine in IE. It looks for checkboxes named market, although I use market[$id] for each checkbox. Code:
a global checkbox onclick that takes the name of of the checkbox and manipulates to get the name of the textbox to be enabled/disabled or a global checkbox onclick that when acheckbox is checked, the textbox in the next td is enabled, when it is not checked, the next textbox is disabled (and alltext is removed from the box).
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:
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.
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:
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:
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'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.

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; }
