I'm encountering an issue with JavaScript namespace conflicts.
To organize my code, I've split my JavaScript objects into different files.
Each file begins with a namespace declaration:
var MySystem = MySystem || {};
However, when I include an object that calls methods from another object in a file placed after it, I encounter a TypeError stating that the object doesn't exist.
Here's an example of the problem:
File 1 Url.js (included first in the HTML document):
var MySystem = MySystem || {};
MySystem.Url = {
objHelper : MySystem.Helper,
init : function() {
"use strict"
if (this.objHelper.isEmpty('string')) {
throw new Error('The string is empty');
}
}
}
File 2 Helper.js (included second in the HTML document):
var MySystem = MySystem || {};
MySystem.Helper = {
isEmpty : function(thisValue) {
"use strict"
return (
typeof thisValue === 'undefined' ||
thisValue === false ||
thisValue === null ||
thisValue === ''
);
}
}
When I call MySystem.Url.init();, I receive:
TypeError: this.objHelper is undefined
if (this.objHelper.isEmpty('string')) {
If I reverse the order of the included files, everything functions correctly.
This is just a simplistic example, but my system comprises numerous objects, each in its own separate file.
What would be the most effective way to address this issue?
