Get Values from URL
var acutal_url = HTTP://my_host.com/account/apps/6/dashboard/6;
what i want is
var pattern_url = HTTP://my_host.com/account/apps/<int:app_id>/dashboard/<int:dash_id> ;
I want app_id & dash_id separately from this URL ..
Is it possible using JavaScript?


Try this
var acutal_url = "HTTP://my_host.com/account/apps/6/dashboard/6"
var app_id = acutal_url.substring( acutal_url.indexOf("/apps/") + 6, acutal_url.indexOf("/dashboard/") );
var dash_id = acutal_url.substring( acutal_url.indexOf("/dashboard/") + 11 );
alert(app_id);
alert(dash_id);


You should use regular expressions, but just in case you want a tool to do it for you, try http://txt2re.com/

I need to check if the value of the input consists of numbers(0-9). Thanks for helping.

You can use Regular Expressions:
var result = /^[\d]+$/.test(yourInput);

Try to use isNumeric like this:
if($.isNumeric( input ) && parseInt(input)<10 && parseInt(input)>=0){
...
}

I have a string
var str="[a54hy 8:45pm],[f57gh 9:20]"
i need to get
[f57gh 9:20pm]
I don't want to use split since the string length can be anything

This worked for me. where id is f57gh
var re='\\['+id + '([a-z0-9: ]+)\\]';
var rematch=RegExp(re,'g');
var mydata=str.match(rematch);
alert(mydata); //[f57gh 9:11am]

I have an html link like this:
<li id="schedule">
text
</li>
I would like to change the link (href attribute) that this anchor tag points to using javascript.
In my case, I would like to replace the value of the sku in the query string (ie replace '102333' with another number).

try this: http://jsfiddle.net/mig1098/ex6efsce/
var d = document.getElementById('schedule');
var chil = d.children[0];
var data = prompt('your data');
chil.setAttribute('href','/schedule?sku='+data);
alert(chil);
var url = chil.getAttribute('href');
var m = url.replace(/\/schedule\?sku\=/,'');
var r = document.getElementById('resp');
r.value = m;

how would I check for string
<something> in var string = "some chars <something> somechars"

You can use String.match():
var res = string.match(/<something>/g); // ["<something>"]
If there is no match, the value of res will be null. See example on JSFiddle.
