The task is to detect whether the user has installed Adobe Flash player or not with the help of JavaScript. we're going to discuss 2 techniques.

Approach:

Create a ShockwaveFlash.ShockwaveFlash object.
If the instance's value is true, Flash is installed.
If any error occurred, Use navigator.mimetypes property to know whether the flash is installed.

Example 1: This example checks whether the flash player is installed or not.

html

<h1 style="color:green;">

</h1>

<p id="GFG_UP">
</p>

<button onclick="GFG_Fun()">
    click here
</button>

<p id="GFG_DOWN">
</p>

<script>
    var el_up = document.getElementById("GFG_UP");
    var el_down = document.getElementById("GFG_DOWN");
    
    el_up.innerHTML = "Click on the button to check"+
            " whether Adobe Flash is installed or not";
    
    var Flash = false;
    
    function GFG_Fun() {
        try {
            Flash =
            Boolean(new ActiveXObject('ShockwaveFlash.ShockwaveFlash'));
        } catch (exception) {
