How to substring in jquery

How can I use jquery on the client side to substring "nameGorge" and remove "name" so it outputs just "Gorge"?

var name = "nameGorge"; //output Gorge

How about the following?

<script charset='utf-8' type='text/javascript'>
  jQuery(function($) { var a=$; a.noConflict();
    //assumming that you are using an input text 
    //  element with the text "nameGorge"
    var itext_target = a("input[type='text']:contains('nameGorge')");
    //gives the second part of the split which is 'Gorge'
    itext_target.html().split("nameGorge")[1];
    ...
  });
</script>

Yes you can, although it relies on Javascript's inherent functionality and not the jQuery library.

http://www.w3schools.com/jsref/jsref_substr.asp The substr function will allow you to extract certain parts of the string.

Now, if you're looking for a specific string or character to use to find what part of the string to extract, you can make use of the indexOf function as well. http://www.w3schools.com/jsref/jsref_IndexOf.asp

The question is somewhat vague though; even just link text with 'name' will achieve the desired result. What's the criteria for getting your substring, exactly?

Using .split(). (Second version uses .slice() and .join() on the Array.)

var result = name.split('name')[1];
var result = name.split('name').slice( 1 ).join(''); // May be a little safer

Using .replace().

var result = name.replace('name','');

Using .slice() on a String. 

var result = name.slice( 4 );

You don't need jquery in order to do that.

var placeHolder="name";
var res=name.substr(name.indexOf(placeHolder) + placeHolder.length);

Standard javascript will do that using the following syntax:

string.substring(from, to)

var name = "nameGorge";
var output = name.substring(4);

That's just plain JavaScript: see substring and substr.

No jQuery needed! Just use the substring method:

var gorge = name.substring(4);

Or if the text you want to remove isn't static:

var name = 'nameGorge';
var toRemove = 'name';
var gorge = name.replace(toRemove,'');
