    Hello Reader's! If you want to show what the text user has selected in a alert box, Then by using Javascript you can perform this task very quickly.

    Step1:-

    <div>Some test text for you to select</div> 
    

    Make a div that shows the text.

    Now write the JS as follows:-

    function getSelectedText() {
        var text = "";
        if (typeof window.getSelection != "undefined") {
            text = window.getSelection().toString();
        } else if (typeof document.selection != "undefined" && document.selection.type == "Text") {
            text = document.selection.createRange().text;
        }
        return text;
    }
    
    function doSomethingWithSelectedText() {
        var selectedText = getSelectedText();
        if (selectedText) {
            alert("Got selected text " + selectedText);
        }
    }
    
    document.onmouseup = doSomethingWithSelectedText;
    document.onkeyup = doSomethingWithSelectedText;
    

    Now what ever user will select the text, it will be shown in alert box
