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 =
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:
JavaScript Know the value of GET parameters from URL
Example 2:This example get the value of all the parameters 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 =
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");
p_down.innerHTML = a + "<br>" + b + "<br>" + c;
}
</script>
