Although you could quite simply use the selectionchange event to show your 'actionbar' alongside the native functionality, if you would want to 'replace' the native behavior you would need to either fake the entire selections from scratch or use the selectionchange event and the second the the selection is made you wrap the selected text with a coloured span element for example and cancel the real selection (whilst showing your actionbar), the trouble with this method would be that 1) the native actionbar might show for a split second and 2) the experience will be different from what the user is used to possibly having dangerous effects. If on the other hand you would want to do the selections from scratch you should use the user-select css property to disable text selection and next figure out based on the touchstart and thouchend which text to 'select' (with coloured spans) (realistically only possible in an extremely controlled environment (for example a text-only reader application)).

Please note that this will not work in Firefox and Opera as the selectionchange event is not fired there and you would need to use a touchend event handler on the document + stopping bubbling of all other touchend events to support opera mobile and firefox mobile. (Credit for the fact that select doesn't work and selectionchange should be used goes to Tim Down)

jsFiddle Demo with Plugin

The above jsFiddle Demo I made uses a Plugin to allow you to prevent any block of text from being selected in Android or iOS devices (along with desktop browsers too).

This does not interfere with other markup you may have, such as jQuery .click(); event listeners as demonstrated in the jsFiddle.

It's easy to use and here is the sample markup once the jQuery plugin is installed.

Sample HTML:

<p class="notSelectable">This text is not selectable</p>

<p> This text is selectable</p>

Sample jQuery:

$(document).ready(function(){

   $('.notSelectable').disableSelection();

});

Complete jQuery Plugin:

$.fn.extend({
    disableSelection: function() {
        this.each(function() {
            this.onselectstart = function() {
                return false;
            };
            this.unselectable = "on";
            $(this).css('-moz-user-select', 'none');
            $(this).css('-webkit-user-select', 'none');
        });
    }
});

If your aim is to prevent selection, you could use some CSS like

body 
{ 
  -moz-user-select: none;
  -khtml-user-select: none;
  -webkit-user-select: none;
  user-select: none;
}
