Is there a way to convert twitter bootstrap's typeahead function into a $("body").on() function? The following code works fine if the element exists on the page load.

$("#job_title").typeahead({
    source: searchFunction,        
    onselect: function(obj) {            
    }
});

But if I add the text input with id="job_title" dynamically, the above function doesn't work. Is there a workaround for this?

• Oops, yeah that was just a bad paste error. Thanks for pointing that out. but this is not the issue :) – Adam Levitt Commented Jun 14, 2012 at 16:26
• Is it a problem to initialize the typeahead on the element when you add it? – Esailija Commented Jun 14, 2012 at 16:28
• Nope, this code works perfectly if the #job_title element is already on the page inside the HTML. This code only does not work if I dynamically add the #job_title element. – Adam Levitt Commented Jun 14, 2012 at 16:29
• 1 You need to add the code how you create the element and consequently call .typeahead on it. Because jsfiddle/9DxLZ/1 is working just fine. – Esailija Commented Jun 14, 2012 at 16:36

This solution requires no additional javascript. From https://stackoverflow./a/15094730

$("#element-that-will-contain-typeaheads").on("DOMNodeInserted", function () {
    $(this).find(".typeahead").typeahead();
});

I downloaded jquery.livequery.js to get the behavior I wanted:

$("#job_title").livequery("create", function() {
    $(this).typeahead({
        source: searchFunction,        
        onselect: function(obj) {            
        }
    });
});

var fx = {
    "init":function() {
        $("#id_of_an_element").typeahead({
            minLength:2,
            delay:1 ...
        })
    },
    "method2":function(){
        some content;
    }
}

Every time the element containing the typeahead is loaded into the DOM (eg. via AJAX success, call fx.init();
