I'm trying to do the right thing. I currently have a page that doesn't
have any JavaScript and the page works. The page works with CSS on or
off. Now I would like to add some JavaScript to enhance the page. The
JavaScript will rearrange some of the DOM and use CSS.
I am willing to put in the effort to try to ensure that the JavaScript
doesn't do anything if necessary JavaScript support for full
functionality is not available. This seems like a difficult task. I
will do the DOM rearranging onload but before doing this rearranging I
will have to check that even the code in the event handlers will work.
Like I will have to do something like this
if ( /* check every function I need is available */ ) {
// All my JavaScript here
}
Is the best way to do this?
It would be an equal failure if the JavaScript does anything if the CSS
is disabled. Can I check that the CSS is on?
Problem I began with: Netscape/Opera supports hover for different elements, IE only supports hover for <a> and I want to use hover for <td class="menu">
I then found a fix using some Javascript here: http://webpages.charter.net/mmmbeer...rbitrary-hover/
It works ok for IE now.
Problem I now have: I don't want the script to run in a browser that does support hover for <td>.
In other words I noticed that the script was still running for Netscape and Opera - but I would prefer to let those browser's native hover support to work since I notice that in some cases the script can introduce lag at loading time.
I don't want to sniff for IE: I know how unreliable browser sniffing is. I would rather sniff for the lack of hover support.
Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
i have a list of checkboxes, the number of checkboxes is dynamic. All the checkboxes have same name. i am trying to get the length of selected checkboxes.
when i try to get the length in javascript like document.form.name1.length, it works fine if number of checkboxes selected are more than 1, but not for 1.
I have a code that I got from a tutorial website. The goal is when someone clicks the first check box with the value of yes then the two other sets of check boxes will autmatically be checked for no.
The issue is their are three sets of 2 check boxes each.
So here is my code code I am trying to use
PHP Code:
Here is my form code
PHP Code:
So Ideally when a representative clicks that the customer has three services (clicks the Yes checkbox) all the other checkboxes will default to No.
How I would change the above javascript to do this.
I am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the "Buy" button, it allows the order.how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities. Here is the page code and the Javascript code.
I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.
[Code]...
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.
I am looking for a way to embed an IM window into a web page, so that users can easily send an IM to a support person. I am looking for something free and easily implemented, that doesn't require any client download on the user's system. And supports one of the major IM services like Gtalk, AIM, YIM, ICQ, etc.
Basically I want to provide very very simple answering of questions, so along the lines of LivePerson without the cost and extra features.
From what I've read, the JavaScript/DOM support is pretty good for handhelds, but trying a simple page which works on the desktop doesn't work on pocket IE on the device. I know scripting isn't completely disabled, because I can use a script block to write a string, but I haven't been able to call a function to change the string either from a form button click or by adding another script block that calls the function. Both of those work on the desktop. In fact, using a script block to call the function doesn't even work on my device when the string value is written statically in the HTML (so it doesn't have anything to do with using the document.write). Code:
I have a textarea and I would like to prevent users from inserting HTML tags. Only plain text is supported. Which client-side js regular expression is best for this?

I am using a script called osDate and I am trying to modify the sign up form to suit my setup. So far I have the below, but I would like to check a set ofradio buttons, but not sure, how to add it into the current code.
var alphanumeric_chars = "0123456789.+-_#,/ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz ()_"; var alphanum_chars = "0123456789_ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"; var text_chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz /'"; var full_chars = "0123456789.+-_#,/ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz() _$+=;:?'";
how do i know if a browser supports javascript or not ? I implemented some javascript on my site, but noticed that some browsers do not support our scripts. i am using IE 5.0 now on another system, and it doesnt seem to work.
I'm having some problems calling a JS function with a form button.
My function looks like this: function selection(modify, id) { document.frmNews.hideID.value = id; document.frmNews.hideType.value = modify; document.frmNews.submit(); }
The button: <input type="button" name="btnEdit2" value="Edit" OnClick="selection('edit', 2)" />
The button works if I change it's type to a "submit" but that seems to skip the whole function and just submits.
Can anyone shed some light on the JavaScript support on many of the most common mobile browsers (the newest versions of Blazer, Blackberry and Pocket IE)? Specifically, I am trying to render some content using innerHTML when the page loads without success. document.write is supported but does not meet my needs.
I was trying to use a jQuery timer to repeat a function at intervals, but it didn't work in IE. Then I read that IE doesn't support setInterval, which seems amazing. Did I read this right? And if so, what do I use in jQuery to keep repeating a function at intervals? I've tried a few things and they all bomb out in IE, just doing something once, although they work in FF. What works in the execrable IE and real browsers?
at least going to be a double post from in the jQuery Plugin list. I'm being moderated yet on that list, and it doesn't seem to get much activity.I'm going to post this here since the Tablesorter developer hasn't gotten back to me yet.I took a copy of the latest version in SVN and modified it to have jQuery UI Theme support. It seems to work very well and anyone is welcome to use it.[code]I was hoping this would be included into tablesorter so I just threw up the modified version on my work site for now.
I am quite under the impression that I can make any CSS property work across the browser ( By that I mean IE6 ) using jquery. I guess I have written it right. Am I under wrong impression? I mean if it supports Opacity property, it might as well support min-width & min-height.
Every 2 to 3 days I check the ticket system to see how the development of the latest JQueryUI 1.9 is doing and how the JQuery is doing. After several weeks of this I have found way too many tickets about IE6 issues and I started to ask myself why does JQuery and actually, many other projects still try to solve problems for somethings that is beyond repair. With this am talking to the fact that:
I am using a javascript slideshow called fadeshow. (Main code below).
I am wondering if there is a way to have thumbnail support, so I could allow the users to click on a thumbnail and have fadeshow go to that photo in the array. I have gotten a next / previous button working but also would like to add thumbnails.
How would I write an a href link to specify an image in the array?
I would've thought it would be easy, but either there's something I'm missing, or I've been mentally challenged for the past hour.
I have a script that loads an external banner ad page into my main page via ajax. The way the script is setup, you call it from body onload of the main page and the variable for the ad page's location is already set inside the script, so it just places the page/ad in the chosen div'd location. Code:
