Adding GET Parameter to Javascript File

The Idea

In php files, it is common to assign a GET parameter like this

testing.php?1234

What if we want to do the same thing with Javascript file? For example

testing.js?1234

The Logic

Eventhought there is no actual function in Javascript to get a GET parameter when the file called, we can actually tricked it a little :

1. get the whole URL
2. split the values by ? characters

The Code

is actually quite simple

var passedId = requestURL.split('?')[1];

Here, we’re splitting the string and since our file name is testing.js?1234, our split function will resulting in an array :

[0] testing.js
[1] 1234

Since we want to took the 1234 value, we took the value in index 1 of the array

Next?

If you want to add more than 1 parameters, you can create a function to split and detecting the parameter name and parameter value.
