I'm pulling some records out of a database and placing a check
box next to each record that the user can check and use the delete button to delete the record.
I'm looking for some help to create a javascript function that I can fire
off when the user clicks on delete to check if a any records are checked
before submiting the deletion. if no check boxes are checked, I want to alertthe user to make a selection.
I'm thinking about having a loop in this function to loop through the
checkboxes and figuer out if at least 1 box is checked. Code:
I want when checkbox is checked, the span will have 500 USD. When checkbox is unchecked the span will return 0.This is what I've got, have no idea why not work.
Code JavaScript: if ($('#priority').is(':checked')) { $('.presult').text('500 USD');
I just don't get why it's not working. I must be missing something, but I have no idea what. The FORM tag's NAME and ID elements are "inhouse-f2". What else could it be?
I'm using the following code for a checkbox that when clicked, either checks or unchecks a group of checkboxes on a form. The code works fine, except when there is only one checkbox in the group in which case the check all checkbox doesn't work at all.
The code working with three checkboxes in a group is as follows, but remove two of the three and you will see the code stops working:
<script language="javascript" type="text/javascript"> function checkAll( control, cbGroupName ) { var cbGroup = control.form.elements[cbGroupName], i = 0, cb; while( cb = cbGroup[i++] ) { cb.checked = control.checked; }} </script>
I have a page that displays records returned from a database and places a check box next to each record that the end user can check if they want to delete a record. The function below checks to make sure that at least 1 checkbox was checked before allowing the delete to be processed.
this function works just fine when I have more than 1 recored returned, but if I only have 1 record displayed on the page and check it and hit the delete button, I get this error
"Checked" is null or not an object
is there a way to modify the function to fix this problem.
function isCheckBoxChecked(boxgrp) // This function is used to check if any check boxes // are checked before processing { var i = boxgrp.length; do if (boxgrp[--i].checked) return true while (i); alert('Select an Item to Delete'); return false }
When a checkbox is checked, I would like a group of checkboxes on a page to be automatically checked.
I was thinking of going about it like this:
- value of top checkbox = check1 - values of all checkboxes that should be automatically checked (when top checkbox is checked)= check1_1, check1_2, check1_3 etc
- on the onclick event of the top checkbox, a piece of javascript would be executed that would iterate through all the checkboxes.
x = 1; while (x < 10) { check1_(value of x).checked = true; x++; }
How could i go about doing the above in javascript?
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.
trying to build two different functions:#1: Where cDay would be Mo and loops through 24 times:ie: document.delTime."cDay"1.checked = true;button would be <input type="button" name="Mo" value="Check All Mo" onclick="checkAll(Mo)">I have this but cant work out how to parse cDay into the function correctly:
function checkAll(cDay) { document.delTime.Mo1.checked = true; document.delTime.Mo2.checked = true;
I wrote an application that generates HTML based on some database record set. One of the HTML generated is a checkbox with NAME=StudentID. This is to facilitate user to select this user for further processing. This also means that ALL student have a checkbox named StudentID. I do I ensure that only one checkbox is selected at any time before the user proceed with the processing of the selected student.
I have a program that creates dinamically a web page. In the page I have the following function to check how many checkbox are checked.
function tarInfo(info) { var i=0; var c=0; var l=document.forms[0].selected_files.length; alert(l); for (i=0; i<document.forms[0].selected_files.length;i++) { if (document.forms[0].selected_files[i].checked) { c++ } } .. ..
The problem is that if I have only one checkbox, the alert(l) write undefined. If I have more than 2 checkbox, the function works well. Here a part of the webpage with one checkbox.
I am working with a checkbox array where the key is already set. So instead of being able to use name="name[]", I need to use name="name[0]" etc.. I would like a button or a checkbox to select all in the array(name).
The main reason for this is the nature of the checkbox. If a checkbox is not selected then it is completely skipped when looping through the array. To overcome this I added a hidden field of the same name which will assign a value even if the checkbox is not selected. Then the problem of using name[] arises.
The form is populated with hundreds of entries using PHP so I am looking for a way to loop through them all.
Here's a tiny snippet of HTML of how my form is set up.
I want to check all checkboxes using one main checkbox. Then, the checkboxes will be disabled. But then, when the user unchecks the main checkbox, it must revert all the checkboxes to be enabled. How do I do so?

i want to check off a checkbox while i'm typing. for an example if i'm typing "oranges are good" and i have oranges, apples, and blueberry under my check box. i want oranges to be checked of as soon as i type oranges in my phrase "oranges are good". i'm trying to do this using jquery.
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.
Here is the current javascript...

I have a form that is basically a table from my database.I have checkboxes on the left and only those checked get updated on submit.I�m trying to make an function that is called with an onChange event that will check the box if any of the fields in that row are altered. The id of the checkbox is checkeds[i] where �i� is the row number.The function is firing, but the box isn�t getting checked.
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; }
Code JavaScript: <script language=javascript> function apply() { document.frm.sub.disabled=true;
[Code].....
Im using the above code. if, change this code for array of checks box not working. If i change above html code like below , Then how to change javascript?
I think I have what is a simple question: I would like a checkbox to be checked if it is not already when a user types in the text area beside it. Form layout is demo'd below.
<table> <tr> <td><input type="checkbox" name="box[1]" value = "x"></td> <td><textarea name="area[1]">
