Trim , Left trim (ltrim) and Right Trim (rtrim) in javascript

//Function to trim the space in the left side of the string

function ltrim ( s ){

  return s.replace( /^\s*/, "" );

}

//Function to trim the space in the right side of the string

function rtrim ( s ){

   return s.replace( /\s*$/, "" );

}

//*Function to trim the space in the  string

function trim(s) {

   var temp = s;

   return temp.replace(/^\s+/,'').replace(/\s+$/,'');

}

ltrim() will remove all the spaces to the left in a string rtrim() will remove all the spaces to the right in a string trim() will all the left , right and spaces inside the string Ex: var x = " thestring"; ltrim(x) will return "thestring"; var y = "thestring "; rtrim(y) will return "thestring"; var z = " the st ri ng "; trim(z) will return "thestring"
