jQuery and document.ready() firing twice

I know it is quite a common issue, but even with research I was not able to understand what goes wrong in my call to document.ready() Javascript function. For some reason, it gets called twice, even when I don't execute anything else than an alert. As I said in the title, I am using jQuery, and figured something could come from $(function(){}), so I removed any execution in there as well. Nothing changes, document.ready() is still called twice. What can be the origin of this issue? How to troubleshoot/solve it? Thanks in advance! Here's the code I've tried : ``` $(function(){ //$( "#tabs" ).tabs(); }); $(document).ready(function() { //getTableEntity("organisation", "getentitytable", "#testtable"); //standardDataTable('#tableOrga'); alert("document.ready"); }); ``` Edit : I know I'm using the same function twice. Putting everything in one function doesn't solve the problem.
