There is not any function in JavaScript to remove spaces such as (Trim function) In VBScript.

because some browser does not support VBScript so I want to use JavaScript

no, trim doesnt exist but you can use this function to emulate it. Put it in the head of the document and call it like this...


newtxt = trim('fk dns fnds gkejgij');


... and spaces should be removed


function trim(txt){
var tmp = "";
var item_length = txt.length;
var item_length_minus_1 = txt.length - 1;
for (index = 0; index < item_length; index++){
if (txt.charAt(index) != ' '){
tmp += txt.charAt(index);
}else{
if (tmp.length > 0){
if (txt.charAt(index+1) != ' ' && index != item_length_minus_1){
tmp += txt.charAt(index);
}
}
}
}
return tmp;
}
