Question

如果两个不同的选择下降的数值相同,如果它们有相同的“名称”,然后将总价值归入使用舱位的阵列,那么我如何能够在选择(不提交)时将这两个数值加在一起?

EDIT

For a little clarification, I am dynamically creating the list which needs to look like this

BOX A, BOX A, TITLE

BOX B, BOX B, TITLE

BOX C, BOX C, TITLE etc...

每个清单都有所不同,很少相同。随后,这些箱子可以是DE或F。选定(目前为交换) 如果价值不是空的,那么所有相应的箱子都需要加在一起,然后被推入一个适当的阵列。

var s=[sumOfAs, sumOfBs, sumOfCs];

I hope this helps... Also the back end is PHP THANKS!

这里是把第一套价值观推向一阵的支架。

$("#selectionBox select").change(function(){
    s = [];
    $("#selectionBox select option:selected").each(function(){
        $("#selected_songs").text(  );

        var v = $(this).val();
        if(v !=   ){
            s.push(v);
        }
        if(s != ""){ 
            $( #selectionButton ).show(); 
            var mw = $("#list_month_New").val();
            var dw = $("#list_day_New").val();
            var yw = $("#list_year_New").val();
            var t = $("#listTitle").val();
            if(mw == "" || dw == "" || yw == ""){
                $("#songListWarning").show();
            }else{
                $("#songListWarning").hide();
            }
        }else{
            $("#list_month_New").val();
            $("#list_day_New").val();
            $("#list_year_New").val();
            $("#listTitle").val();
            $( #selectionButton ).hide();
        }
    });
    s.sort();
    jQuery.each(s, function(){
            O = "";
            O = this+"<br />";
            str = /&(.+)/.exec(O)[1];
            num = O.replace(/-.*/,   );
            fullString =  <span style="color:black"> +num+ </span> -  +str;
            $("#selected_songs").append(fullString);
    });

I just need to figure out how to add another value to the initial value?

Answer 1

var runningTotals = {};
$( select ).each(function() {
    var $this = $(this);
    var name = $this.attr("name");
    var val = runningTotals[name];
    if (!val) {
        val = 0;
    }
    val += +($this.val());
    runningTotals[name] = val;
});

请参看fiddle。
