Oct 9, 2012
Introduction

Here I will explain how to remove or delete all white spaces from string using
JQuery in asp.net.

Description:
  
In previous articles I explained
jQuery Remove first/last character from string, jQuery Drag and Drop Example and many articles relating to JQuery. Now I will explain how to remove or delete white spaces from string using JQuery in asp.net.

To remove or delete white spaces from string we can use default jQuery function trim() but it will remove only starting and ending spaces but spaces within string will be same because of that we need to use regular expression to remove white spaces from string for that we need to write codesnippet like as shown below

Remove all the white spaces from string


<script type="text/javascript">
$(document).ready(function() {
var str = ' Welcome To Aspdotnet  -  Suresh '
var newstr = str.replace(/\s/g,'') // Remove white spaces from string
alert(newstr);
})
</script>
