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;">
GeeksforGeeks
</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) {
Flash = ('undefined' != typeof navigator.mimeTypes[
'application/x-shockwave-flash']);
}
el_down.innerHTML = Flash;
}
</script>
