javascript - How to select all text in contenteditable div?

Question

Before this is flagged as a duplicate, I want you to realize that no one has actually provided a good answer for this specific question. In select all text in contenteditable div when it focus/click, the accepted answer and Tim Down's answer are both not helpful, as they only work when the element is already focused. In my case, I want all the text in the contenteditable div to be selected after the click of a button, even if the div was not focused beforehand.

How could I do this?

I used some code from this thread to come up with my answer. It's 100% jQuery as you asked for as well. Hope you like it :)

jQuery.fn.selectText = function(){
   var doc = document;
   var element = this[0];
   console.log(this, element);
   if (doc.body.createTextRange) {
       var range = document.body.createTextRange();
       range.moveToElementText(element);
       range.select();
   } else if (window.getSelection) {
       var selection = window.getSelection();        
       var range = document.createRange();
       range.selectNodeContents(element);
       selection.removeAllRanges();
       selection.addRange(range);
   }
};

$("button").click(function() {
    $("#editable").selectText();
});?
