1. Remove Extra Spaces Using JavaScript

This simple script uses regular expressions to remove unwanted extra spaces from a block of text. The following example illustrates the script (you can paste your own text here if you like):

 

To use this script, place the following code in the document head:

function
trimSpaces(){

        s
= document.getElementById("textString").value;

        s
= s.replace(/(^\s*)|(\s*$)/gi,"");

        s
= s.replace(/[ ]{2,}/gi," ");

        s
= s.replace(/\n /,"\n");

       
document.getElementById("textString").value
= s;

}

Place the following code in the document body (modify to suit your needs):

<textarea
name="textString" id="textString" cols="50"
rows="4">

 This
is a block of text with some  extra    spaces in it.   Click the
button to remove them. 

</textarea>
