I have a lot of data stored in associative array.

array = {'key':'value'};

How to loop throught an array like this using an normal for loop and not a loop like here:

As others have pointed out, this isn't an array. This is a JavaScript object. To iterate over it, you will have to use the for...in loop. But to filter out the other properties, youw ill have to use hasOwnProperty.

Example:

var obj={'key1': 'value1','key2':'value2'};



for (var index in obj) {

    if (!obj.hasOwnProperty(index)) {

        continue;

    }

    console.log(index);

    console.log(obj[index]);

}
