I'm try to run this function, which grabs all the checked checkbox values in to a comma separated string, and converts , in to , , so it reads better. The problem is I'm getting a strange error:

$('.name_boxes').live('click', function() {

    var all_boxes = $('.name_boxes');

    var all_boxes_values = []

    for (var i = 0; i < all_boxes.length; i++) {

        if (all_boxes[i].checked) {

            all_boxes_values.push(all_boxes[i].value)

        }

    }

    var all_boxes_values_clean = all_boxes_values.replace(/,/g,, );

    alert(all_boxes_values_clean);

});

The console error says:

Uncaught TypeError: Object Aaron Ramsey,Aaron Renfree has no method 'replace'.

I'm not getting the alert box.

This is a bit beyond me, can anybody explain what I'm doing wrong?

Although alert(some_array) prints a string representation of the array, the array itself is not a string. Thus, it does not have .replace. alert is forced to convert it into a string because the alert box can only show characters.

You can simply join using a custom separator, though. join is a function of arrays:

var all_boxes_values_clean = all_boxes_values.join(, );

As a side note, I recommend console.log over alert because it:

shows the actual object/array instead of a string representation (especially useful with objects instead of the useless [object Object] you receive with alert)

frees you from closing the popup each time

keeps track of other logs so that you have an actual log of logs
