JavaScript Know the value of GET parameters from URL

In order to know the parameters, those are passed by the “GET” method, like sometimes we pass the Email-id, Password, and other details. For that purpose, We are using the following snippet of code. 

Example-1: This example get the value of “a” parameter from the URL. 

html

<h1 style="color:green;">
    GeeksforGeeks
</h1>

<button onclick="myGeeks()">
    Click here
</button>

<p id="GFG_down" style="color:green;">
</p>

<script>
    function myGeeks() {
        var GFG_url_string =
"https://ide.geeksforgeeks.org/login.php?a=GeeksForGeeks&b=100&c=Computer Science portal for Geeks";
        var GFG_url = new URL(GFG_url_string);
        var c = GFG_url.searchParams.get("a");
        var p_down = document.getElementById("GFG_down");
        p_down.innerHTML = c;
    }
</script>

Output:

"https://ide.geeksforgeeks.org/login.php?a=GeeksForGeeks&b=100&c=Computer Science portal for Geeks";
        var GFG_url = new URL(GFG_url_string);
        var a = GFG_url.searchParams.get("a");
        var b = GFG_url.searchParams.get("b");
        var c = GFG_url.searchParams.get("c");
        var p_down = document.getElementById("GFG_down");
