这个 Javascript 函数可以用 jQuery 重写吗？ [关闭]

Question

我有一个与 Cold Fusion 集成的遗留 JS 函数，用于输出包含在 if 语句中的第 n 个 ID 表单字段。有时输出非常高，看起来非常多余和麻烦。我在想一个 for 循环可以解决这个问题，但不确定解决它的正确方法。下面是来自示例输出的遗留代码。任何帮助表示赞赏：

function checkFinalDisposition(){
if (document.getElementById("mrostatus").value == "Completed"){


    var checkfinal = document.getElementById("finaldisposition").value
    if (checkfinal == 'NEGATIVE' || checkfinal == 'NEGATIVE DILUTE'){
        var checkfinalpass = 'Yes'

        if (document.getElementById("id4735721").value != 'NEGATIVE' || document.getElementById("id4735721").value != 'NEGATIVE DILUTE'){
            var checkfinalpass = 'No'
        }
        if (document.getElementById("id4735722").value != 'NEGATIVE' || document.getElementById("id4735722").value != 'NEGATIVE DILUTE'){
            var checkfinalpass = 'No'
        }
        if (document.getElementById("id4735723").value != 'NEGATIVE' || document.getElementById("id4735723").value != 'NEGATIVE DILUTE'){
            var checkfinalpass = 'No'
        }
        if (document.getElementById("id4735724").value != 'NEGATIVE' || document.getElementById("id4735724").value != 'NEGATIVE DILUTE'){
            var checkfinalpass = 'No'
        }
        if (document.getElementById("id4735725").value != 'NEGATIVE' || document.getElementById("id4735725").value != 'NEGATIVE DILUTE'){

我会有一个你正在检查的 ids 的 js 数组，

idToCheck = ['id4735721', 'id4735722', ...];

然后在 for 循环中比较它们。

for(id in idToCheck){
      if($('#'+idToCheck[id]).val() != 'NEGATIVE' || if($('#'+idToCheck[id]).val() != 'NEGATIVE DILUTE'){
            checkfinalpass = 'No';
      }
}

我没有重做您的整个代码，但希望这会为您指明正确的方向。
