So I'm searching for a good crash course on localstorage and interacting with it in Javascript. I want to build a to-do list webapp with some extra functionality but it would be just for 1 user. I don't want to mess with php/mysql and have the server doing anything. Links to tutorials would be best :-D
i m suffering with Passing values from javascript function to controller in cakephp and get using $_POST.
i have tried it by different ways but didn't get success please suggest........
I'm not that good with regular expressions...
I need a JavaScript regular expression that will do the following:
The string can contain letters (upper and lower case), but not punctuations such as éàïç...
The string can contain numbers (0..9) anywhere in the string, except on the first position.
The string can contain underscores (_).
Valid strings:
foo
foo1
foo_bar
fooBar
Invalid strings:
1foo -- number as first character
foo bar -- space
föo -- punctuation ö
Many thanks!
i use this javascript syntax for validating a checkbox...
alert(document.getElementById("ctl00_ContentPlaceHolder1_Chkreg").checked);
if (document.getElementById("ctl00_ContentPlaceHolder1_Chkreg").checked == false) {
document.getElementById("ctl00_ContentPlaceHolder1_ErrorMsg").innerHTML = "please select the checkbox";
document.getElementById("ctl00_ContentPlaceHolder1_Chkreg").focus();
return false;
}
My alert showed me false but my if loop is not working... Any suggestion...
Is there any API or a jQuery plugin that allow me to highlight a code on my website?
For example
<pre code="c#">
var x = new StringBuilder();
var complex = new Complex();
</pre>
<script type="text/javascript">
$("pre[code]").codehighlight({ language: "c#" });
</script>
Something like that?
Hello all,
How do I remove numbers from a string using Javascript?
I am not very good with regex at all but I think I can use with replace to achieve the above?
It would actually be great if there was something JQuery offered already to do this?
//Something Like this??
var string = 'All23';
string.replace('REGEX', '');
I appreciate any help on this.

Hey Guys, I was wondering if there is a "maximum" of data a javascript application can store. I guess this is handled by the browser and that each one has it's limitation? Am I guessing right? Wrong? If there isn't a limit, will a page file be created (wouldn't be very secure I guess).
We have javascript files that are environment specific, and so I was thinking of going down the path of creating a generic way to read in an XML (config) file to store different environment specific settings. I was curious to know if anybody else on here does that (or if not, is there a reason why you don't)?
Am unable to add elements to a dropdown list via Javascript.

I want to run a javascript snippet inside the <head> tag. Is that possible to do that in Selenium RC+Java?

Any Ideas?

But is there any browser which does?

Hi,
I'd like to mimick iPhone main screen in JavaScript on Safari / Chrome / Firefox.
By mimicking I mean:
- Having a couple of pages
- Switching between the pages by clicking & dragging / swiping with my mouse
- Having those dots from the bottom iPhone main screen displaying which page it is
The closest to what I want is:
http://jquery.hinablue.me/jqiphoneslide/
But the sliding doesn't work nearly as good as in iPhone (i have to slide first, and the animation appears after i release the mouse button), and there are no dots at the bottom.
I am new to the lower level useful functions of JavaScript, and I find myself needing to compare two date objects, but within an hourly range. For example, if Date1 is less then two hours until (or from) Date2. How could this be done?
