Question

我想在函数sumMon1完成后调用函数sumWH。这两个函数都从标签获取文本，对它们的值求和，并更新计数器标签。我试图在sumMon1之后调用sumHW的代码在下面，并且不起作用。

$.when(sumMon1()).done(function () {
    sumWH();
});

求和函数如下：

<script>
$.when(sumMon1()).done(function () {
    sumWH();
});

function sumWH() {
    alert(event.target);

    //Get Friday AM Out Value
    var a = parseInt($('[id$="lblWeek1FridayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM IN Value
    var b = parseInt($('[id$="lblWeek2FridayTotalHrs"]').val(), 10) || 0;
    //Get Friday PM Out Value
    var c = parseInt($('[id$="lblWeek1SaturdayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM IN VALUE
    var d = parseInt($('[id$="lblWeek2SaturdayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM Out Value
    var e = parseInt($('[id$="lblWeek1SundayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM IN Value
    var f = parseInt($('[id$="lblWeek2SundayTotalHrs"]').val(), 10) || 0;
    //Get Friday PM Out Value
    var g = parseFloat($('[id$="lblWeek1MondayTotalHrs"]').val(), 10);
    //Get Friday AM IN VALUE
    var h = parseInt($('[id$="lblWeek2MondayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM Out Value
    var i = parseInt($('[id$="lblWeek1TuesdayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM IN Value
    var j = parseInt($('[id$="lblWeek2TuesdayTotalHrs"]').val(), 10) || 0;
    //Get Friday PM Out Value
    var k = parseInt($('[id$="lblWeek2WednesdayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM IN VALUE
    var l = parseInt($('[id$="lblWeek1WednesdayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM Out Value
    var m = parseInt($('[id$="lblWeek2ThursdayTotalHrs"]').val(), 10) || 0;
    //Get Friday AM IN Value
    var n = parseInt($('[id$="lblWeek1ThursdayTotalHrs"]').val(), 10) || 0;
    var result = a + b + c + d + e + f + g + h + i + j + k + l + m + n;

    if (result > 0 && result < 81 && !isNaN(result)) {
        $('[id$="txtTotalHours"]').html(result);
    } else if (result == 0) {
        $('[id$="txtTotalHours"]').html(0);
    } else if (isNaN(result)) {
        $('[id$="txtTotalHours"]').html(result);
    }
}
</script>

 <script>
        $(document).ready(function () {
            sumMon1();
            $('[id$="txtWeek1MondayPM_OUT"], [id$="txtWeek1MondayAM_OUT"]').on("blur", function () {
                sumMon1();
            });
        });

        function sumMon1() {

            //Get Monday AM Out Value
            var Out2Dec = $('[id$="txtWeek1MondayAM_OUT"]').val();

            //split dec and whole AM OUT
            var OutAmDec = Out2Dec % 1;
            var OutAMWhole = Math.floor(Out2Dec);
            if (OutAMWhole < 12 && OutAMWhole != 0 && !isNaN(OutAMWhole)) {
                OutAMWhole += 12;
            }


            //Get Monday AM IN Value
            var In2Dec = $('[id$="txtWeek1MondayAM_IN"]').val();
            //split dec and whole AM IN
            var InAmDec = In2Dec % 1;
            var InAmWhole = Math.floor(In2Dec);

            //Get Monday PM Out Value
            var Out1Dec = $('[id$="txtWeek1MondayPM_OUT"]').val();
            //split dec and whole PM OUT
            var OutPmDec = Out1Dec % 1;
            var OutPMWhole = Math.floor(Out1Dec);
            if (OutAMWhole < 12 && OutAMWhole != 0 && !isNaN(OutAMWhole)) {
                OutPMWhole += 12;
            }

            //Get Monday AM IN VALUE
            var In1Dec = $('[id$="txtWeek1MondayPM_IN"]').val();
            //split dec and whole PM IN
            var InPmDec = In1Dec % 1;
            var InPMWhole = Math.floor(In1Dec);


            //calculate times
            var InAmVal = (InAmWhole * 60) + (InAmDec * 100);
            var OutAmVal = (OutAMWhole * 60) + (OutAmDec * 100);

            var InPmVal = (InPMWhole * 60) + (InPmDec * 100);
            var OutPmVal = (OutPMWhole * 60) + (OutPmDec * 100);


            var Difference = (OutAmVal - InAmVal) + (OutPmVal - InPmVal);
            var result = Difference / 60;
            //display result
            if (result > 0 && !isNaN(result)) {
                $('[id$="lblWeek1MondayTotalHrs"]').html(result.toFixed(2));
            } else {
                var value2 = (result.toFixed(2) * -1);
                $('[id$="lblWeek1MondayTotalHrs"]').html(value2);
            }

        }
</script>

sum函数位于单独的脚本标记中。 sumMon1设置为使一系列文本框变得模糊。

这是使此功能起作用的一种方法，还是有一种更好的方法来实现此功能？

Answer 1

jQuery.when用于异步功能。异步类似于setInterval或jQuery.ajax。除了异步内容外，JavaScript（或几乎所有其他语言）都按顺序从上到下运行代码。

您的代码未使用异步事物。简单地做

sumMon(); sumWH();

如何在另一个脚本结束后调用javascript函数执行
