Basically, I want to be able to detect:

1. if there is highlighted text inside of a text input
2. How to remove the selected text

I set up a fiddle to show how far I got, but I can't figure out how to remove the given text.

/

Here is my markup

<input type='text' value='Hello World!' id='txtbox' />
<br />
<button id="btnSelect">select text</button>
<button id="btnRemove">remove selected text</button>

and my javascript

$("#btnSelect").click(function () {
    document.getElementById('txtbox').setSelectionRange(6, 12);
});
$("#btnRemove").click(function () {
    if (window.getSelection) {
        if (window.getSelection().deleteFromDocument) {
            window.getSelection().deleteFromDocument();
        }
    }
});

• javascript
• html
• dom

• if you know your range can you the use splice() ? – Mina Gabriel Commented Aug 8, 2013 at 18:55
• This fiddle is a functional example. In real world usage, I will not know my range. – Smeegs Commented Aug 8, 2013 at 18:55
• There are lots of posts here on stackoverflow that address this sort of issue. Google js delete text from textarea or jquery textarea get selected text – SaganRitual Commented Aug 8, 2013 at 18:59

Depending on browser patibility (ie9+ and others) you could use selectionEnd, selectionStart:

$("#btnRemove").click(function () {
    var ele  = document.getElementById('txtbox');
    var text = ele.value;

    text = text.slice(0, ele.selectionStart) + text.slice(ele.selectionEnd);
    ele.value = text;
});
