Javascript select all text in field upon clicking

I was able to find this code upon searching. I dont know enough about javascript to know if it will do what I need. Anyone able to take a look?

Here is original thread

javascript - Select text with just one click - Code Review Stack Exchange

function SelectText(element) {

    var doc = document,

        text = doc.getElementById(element),

        range,

        selection;

    if (doc.body.createTextRange) {

        range = document.body.createTextRange();

        range.moveToElementText(text);

        range.select();

    } else if (window.getSelection) {

        selection = window.getSelection();       

        range = document.createRange();

        range.selectNodeContents(text);

        selection.removeAllRanges();

        selection.addRange(range);

    }

}

$(function() {

    $('p').click(function () {

        SelectText('autoselect');

    });

});

Thanks george. Yes it seems there is no way to do this. I was able to add buttons to highlight the field but now ill need 50 buttons next to every box...seems like such a common thing to not have a solution to.

That code is designed to work with an HTML form and won't work with a PDF form.

I think the best you can do for a field in a PDF is the following in the Mouse Enter event:

// Mouse Enter script for text field

event.target.setFocus();

Selecting all of the text is a side-effect of using the setFocus method. What I suggested results in non-standard behavior, but it might be OK for your needs.
