Firebug returns an error saying msg.elements is undefined. I'm trying to make a function that will enabled a delete button if any of the check boxes in a list are checked.
function selectone () {
var msg = document.getElementsByName('pm');
var i = 0;
for(i; i < msg.elements.length; i++){
if(msg.elements[i].checked == true){
document.getElementById('multiple_action').disabled = false;
document.getElementById('drop_button').setAttribute("class", "drop_button");
}else{
document.getElementById('multiple_action').disabled = true;
document.getElementById('drop_button').setAttribute("class", "drop_button disabled");
}}}
I'm getting an error message that says that my function is null or undefined. I figure it' something simple, like maybe a ( instead of {, but I can't seem to find it.
Here's the script from the header: Code: <script type="text/javascript"> var time = new Date(); var dayNight = time.getHours(); function displayImage() { if (dayNight >= 9 && dayNight <= 14) { .....
And from the body: Code: <body onload="displayImage()"> <div> <img id="highlights" src="" alt=""/> </div> </body>
I'm poking around with objects and the differences of creating a variable outside an object and inside an object. Here's my code.This is just before the closing body tag:
Code JavaScript: <script type="text/javascript"> // Creating an object[code]....
When i reload the page, i get an alert box stating the 1st message "Hello there" When i click on OK on the alert prompt. I get another prompt that says Undefined. I tried experimenting and found out that if i call the another() function within myObj without alerting it like so:
Code JavaScript: myObj.another();
Then i just get an alert prompt with "Hello there" only...the second undefined message doesn't appear.
I don't know the reason of getting the message as 'undefined' in alert dialog box, whenever I do the post request to servlets from jquery after clicking login button.Here's the code which's making me bugged:
the request is passing to servlets(which is mapped to Check.do URL), and in doPost method in servlets I'm just doing: response().getWriter().write("Hello");May I know the what's the reason of getting error in above code, and how can I sort this problem out?
I started getting a wierd problem with my jscript program. Here im using jscript for client-side validation and upon email field submission,im getting undefined value with an error saying "length is null or not an object". All the values of fields prior to that are being obtained properly.
The following excerpt is part of a very huge project(in terms of code involved). Pardon me if it lacks a bit of context. But I assume I have posted adequate information for understanding the problem.
But when I alert the status of the checkboxes they show up as "undefined". As you can see, the first piece of code defines a titlebar with a button and a couple of checkboxes and the name of the titlebar. And it is these checkboxes that remain undefined even though I can see them and check and uncheck them. But the name of the titlebar gets passed to the function correctly when the onclick event fires and it gets alerted.
I am trying to remove a validation message from the screen when a user checks a checkbox. I do require that the user enter a last name in a text box before they click the submit button. If they dont, the validation message appears. I am trying to hide or clear that validation message when they select a check box on the page. The HTML for it is below but am wondering if you canremove the messagein JQuery.[code]...
I am creating a form in which a checkbox is checked based on the info from previous page.The info I am passing is the client ID (which is a number I can pass in the URL variable)In the form I have a list of clients (with checkboxes next to them)Now if you come from a specific client page the checkbox with the client name should be already checked since you are getting info regarding that client, with the option of selecting other clients.So any idea on how I can accomplish this using Javascript?
I am using a checkbox to turn on and off some labels on a line on a google map, which is working fine if the line is already drawn, using this function:
function distboxclick(labelsbox) { if (labelsbox.checked) { for (var i=0; i<distmarkers.length; i++) { if (distmarkers[i].mLabel != null) distmarkers[i].mLabel.show(); } } else { [Code]....
but the thing is that I want the labels to be turned off to begin with and switched on if the box is checked.
Does anyone know why the onclick in the following popup menu gives the error:"Val is undefined"? Does it have something to do with the fact that it is called within the variable tablePop? Because it IS displayed properly as part of the popup text, where it is called outside the single quotation marks (see [***]). It is only in the onclick that it's causing problems. Code:
I am working on a site and have put some javascript in to control the size of the image that gets displayed on the page, however it runs ok but always returns an error after loading, and I can't find a cause. Code:
I've written a javascript function that checks for a php session. When there is no session, it works okay. But when there is a session, I get an "undefined" javascript error.
This is my js in question. I call sessionCheck() in body onLoad. If there is no session, I will get my alert of "it is null"
Code: function getUser() { return "<?php getSessionUser(); ?>"; }

I have a webpage that gives a quote (simple math). I recently revamped my entire website and when I went to place the page into the new site it will not work. It seems to not be doing anything at all. the page is at www.rwinvite.com/quote.html it uses quote.js which is in the same directory with the page. the html and js code is long, not complicated, but there are a lot of variables. This was working before I had the website redone, but I have no idea. I did run firebug and it tells me...
