Execute a JavaScript function when user selects some text in an html file

Issue

I have an html file that displays some text. I need to call a JavaScript function when the user selects some text on it. I have the following code but the highlightSelection() function never gets called.

window.onselect = highlightSelection;

function highlightSelection() {

}

Is there any other way to call a JS function while user selects some text?

Solution

you need to put the text in the appropriate element, an example:

<input type="text" value="This is some selectable text" onselect="showMsg()" />

function showMsg(){

}
