Question

Im passing some values with ID’s from selected check box’s

Im collecting the values in an array to post however I also want to sum the values in the titles but I cant get it to do this…

where am I going wrong ? I know its in the calling of the variable that is returned but im not sure how to GET it

function doAlloMath(){


        var sum=0;

        alert($("input[name=alloInv]:checked").map(function () {return this.value;}).get().join(","));
        alert($("input[name=alloInv]:checked").map(function () {return this.title;}).get().join(","));
        alert($("input[name=alloInv]:checked").each(function (a,b) {sum += parseFloat ($(this.title)); return sum;}).get());



    }

A checkbox does’nt have a value unless it’s explicitly set. To see if the checkbox is checked or not you need to use prop('checked');

You could try something more like this:

function doAlloMath() {
    var sum = 0,
        elm = $("input[name=alloInv]:checked"),

        values = elm.map(function() {
            return this.value;
        }).get().join(","),

        titles = elm.map(function() {
            return this.title;
        }).get().join(",");

    elm.each(function(idx, elem) {
        sum += parseFloat(this.title);
    });

    console.log(sum);
    console.log(values);
    console.log(titles);
}​
