Javascript 如果语句test=true但赢得'；不执行？

在此单击处理程序代码中：

$('#save').click(function () {
            if (overAllStatus == 'red') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleRed.png" width="20" height="20"></a>';
            }
            else if (overAllStatus == "yellow") {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleYellow.png" width="20" height="20"></a>';
                console.log('Over all status is yellow.');
            }
            else if (overAllStatus == 'greenR') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleGreenHollow.png" width="20" height="20"></a>';
            }
            else if (overAllStatus == 'greenN') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleGreen.png" width="20" height="20"></a>';
            }
            comments = $('#comments').val();
            $("body").trigger(esc);
            $("#save1").trigger('click');
            redListSize = 0;
            yellowListSize = 0;
            console.log("save clicked");
        });

我只看到控制台中打印的“保存已单击”。测试条件下的代码似乎没有执行。我不明白为什么。

试试这个，用这个替换你的代码，看看“overAllStatus”在你的“click”回调中有什么值

$('#save').click(function () {
            console.log("overAllStatus", overAllStatus);  //use this to check the value of overAllStatus

            if (overAllStatus == 'red') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleRed.png" width="20" height="20"></a>';
            }
            else if (overAllStatus == "yellow") {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleYellow.png" width="20" height="20"></a>';
                console.log('Over all status is yellow.');
            }
            else if (overAllStatus == 'greenR') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleGreenHollow.png" width="20" height="20"></a>';
            }
            else if (overAllStatus == 'greenN') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleGreen.png" width="20" height="20"></a>';
            }
            comments = $('#comments').val();
            $("body").trigger(esc);
            $("#save1").trigger('click');
            redListSize = 0;
            yellowListSize = 0;
            console.log("save clicked");
        });

$（'#保存'）。单击（函数（）{
log（“overAllStatus”，overAllStatus）；//使用它检查overAllStatus的值
如果（总体状态==‘红色’）{
行[lastRowClicked]。单元格[0]。innerHTML=''；
}
else if（整体状态==“黄色”）{
行[lastRowClicked]。单元格[0]。innerHTML=''；
log（'总体状态为黄色'）；
}
else if（总体状态=='greenR'）{
行[lastRowClicked]。单元格[0]。innerHTML=''；
}
else if（总体状态=='greenN'）{
行[lastRowClicked]。单元格[0]。innerHTML=''；
}
comments=$（'#comments'）.val（）；
$（“主体”）。触发器（esc）；
$（“#save1”）.trigger（'click'）；
redListSize=0；
yellowListSize=0；
console.log（“单击保存”）；
});

如果您使用的是jQuery，请更新问题的标签。而JSFIDLE在这里可能会有所帮助。控制台会为“overAllStatus=='red'”打印什么？如果它不执行，那么

overAllStatus

就不是

“黄色”

。在代码中放入一些

console.log（）

调用，以便在代码运行时观察值。您可以使用“断点”停止代码并检查变量值！您什么时候测试overAllStatus的值？单击“保存”时，您很可能会有不同的overAllStatus值。这意味着“overAllStatus”中没有任何值，请搜索您的代码以查看定义它的位置。我怀疑您是否遗漏了变量声明前面的“var”？或“总体状态”未定义为全局变量。

$('#save').click(function () {
            console.log("overAllStatus", overAllStatus);  //use this to check the value of overAllStatus

            if (overAllStatus == 'red') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleRed.png" width="20" height="20"></a>';
            }
            else if (overAllStatus == "yellow") {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleYellow.png" width="20" height="20"></a>';
                console.log('Over all status is yellow.');
            }
            else if (overAllStatus == 'greenR') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleGreenHollow.png" width="20" height="20"></a>';
            }
            else if (overAllStatus == 'greenN') {
                rows[lastRowClicked].cells[0].innerHTML = '<a class="modalInput" rel="#flagsSummary" style="cursor:pointer"><img src="/FatcaOne_0/static/images/circleGreen.png" width="20" height="20"></a>';
            }
            comments = $('#comments').val();
            $("body").trigger(esc);
            $("#save1").trigger('click');
            redListSize = 0;
            yellowListSize = 0;
            console.log("save clicked");
        });
