a.indexOf()

TypeError: a.indexOf is not a function blogger

This error might be caused by the jQuery event-aliases like .load(), .unload() or .error() that all methods are deprecated since jQuery 1.8.

Please check these aliases methods in your code and replace them with the .on() method instead.

As an Example,

Replace the following deprecated excerpt:

$(window).load(function(){
    //TODO
});

With the following:

$(window).on('load'function(){ 
    //TODO
});

I hope these solutions will help you a lots.
