How can I utilize selectionStart?

As I understood, selectionStart must return start position from selected text in input text or textarea elements

I have this js code

 $("#inpt").on("mouseup" , function () {
    alert( $("#inpt").selectionStart);
});

and html

<input id="inpt" type="text" value="bla bla bla" />

When I select some part in text "bla bla bla" the result is "undefined". Yell please, where did I go wrong ?

Solution

  • Try this.selectionStart, it's not the property of jQuery object, but the HTMLInputElement's property.

    $("#inpt").on("mouseup" , function () {
    console.log(this.selectionStart);
});
