Useful snippet for debugging javascript. It prints out key-value pairs of associative array. In PHP your have function print_r($array), but in Javascript you still have to make your own function.

   $.each(myAssociativeArr, function (idx, obj) {
         $.each(this, function(key, val){ 
             console.log(key, val)
           })
     })

 

You can fill associative array, for example, this way:

        //Initialize array in Javascript
        var myAssociativeArr = [];
        //Add element to array
        myAssociativeArr.push( {
                id: 1,
                title:  "my title 1",
                url: "http://url1",
                css: "myCssClass1",
                txtdescription: "my text description 1"
        });

        myAssociativeArr.push( {
                id: 2,
                title:  "my title 2",
                url: "http://url2",
                css: "myCssClass2",
                txtdescription: "my text description 2"
        });
