Question

I’m have a set of checkboxes and an array that contains the index of which checkboxes should be selected. I’m trying to loop through the array and for each index in it. I made a sample jsFiddle to give you guys an idea of what I’m trying to do. I have the JQuery library also if that makes things easier. http://jsfiddle.net/7EetA/1/

Try this:

var arrx=new Array();
arrx[0]=4;       
arrx[1]=5;
arrx[2]=3;
arrx[3]=1;
for (var i = 0; i < arrx.length; i++) {
    document.getElementsByName('cal')[arrx[i]].checked = true;
}
