Use JavaScript to iterate through

    <script type= "Text/javascript" >        $ (function () {            var allcomnum = [];//defines an array of variables            var result = 0;//defines a variable            $ (". Com_num1"). each (function (i, n) {///loop                Allcomnum.push (parseint ($ (N). Val ()));            });            for (var i = 0; i < allcomnum.length; i++) {                result + = Allcomnum[i];            }            $(". Shopcartnum "). HTML (result);        });    </script>

The push () method adds one or more elements to the end of the array and returns the new length.

Each () method specifies the function to run for each matching element.

The parseint () function parses a string and returns an integer.
