The Sample shows a Functions to repalce a character in the string .
The Below Function shows how we can write a extendeed function to a string in javascript.
We have many function for string something like charAt(), indexOf(). but we don,t
have function that is used to replace a character in a string.
The below example shows that how we can write extensoin functions in javascript
and also use that function.
String.prototype.replaceAt = function (i, char) {
return this.substr(0, i) + char + this.substr(i + char.length);
}
Now we access the above function like the below shown
document.getElementById('txtname').value .replaceAt(2, "0")
txtame is the Id of the TextBox and .value returns a string . To that string we are appliying
a extended function replaceAt();
