Replace this Qualifier With Local Variable (JavaScript)
In This Article
Replaces the suspicious use of the “this” qualifier in the inner function with a new local variable declared (and assigned) in the outer scope.
#Availability
From the context menus or via shortcuts:
- when the caret is on the suspicious “this” qualifier in an inner function.
#Example
var Sum = new function () {
var element1 = document.getElementById("sumElement1");
var element2 = document.getElementById("sumElement2");
ProcessClick();
this.val1 = parseInt(element1.nodeValue);
this.val2 = parseInt(element2.nodeValue);
Proc = function () {
return this.│val1 + this.val2;
}
var resElement = document.getElementById("result");
resElement.nodeValue = this.Proc();
};
Result:
var Sum = new function () {
var element1 = document.getElementById("sumElement1");
var element2 = document.getElementById("sumElement2");
ProcessClick();
this.val1 = parseInt(element1.nodeValue);
this.val2 = parseInt(element2.nodeValue);
var val1 = this.val1;
var val2 = this.val2;
Proc = function () {
return val1 + val2;
}
var resElement = document.getElementById("result");
resElement.nodeValue = this.Proc();
};
