Trim function in javascript using prototype
by rajesh[ Edit ] 2007-11-29 15:21:15
This is a function that can be used to do trim operation on any javascript string variable.
String.prototype.trim = function() {
return this.replace(/^s+|s+$/g,"");
}
We have added add a new function to the String Object itself. So it can be used as any other string functions like indexOf() or split() or charAt()....
Usage:
String.prototype.trim = function() {
return this.replace(/^s+|s+$/g,"");
}
var str = "sdfsdf ";
var result = str.trim();
alert(result);
The result will not have the space in the end.
We can add functions to any javascript objects like String, Array etc using the prototype call. May be I or some one will write later on prototypes in javascript....
