jQuery Tip: How to find out if the text in a textbox is selected with jQuery

Here, we’re sharing a jQuery tip. This tip will help you to know if the text in a text box is <input type=”text” /> selected or not. The result will be true or false.



In HTML code, there is one textbox with id “text_selected“. We are triggering a function on a button and alerting the results.

jQuery Code

function isTextSelected(input) {
    if (typeof input.selectionStart == "number") {
        return input.selectionStart == 0 && input.selectionEnd == input.value.length;
    } else if (typeof document.selection != "undefined") {
        return document.selection.createRange().text == input.value;

Above jQuery code will tell you whether or not all of the text is selected within a text input. It will work on all major browsers.
