我有一个链接 RESET YEAR 正在调用一个 servlet，它正在检查当前年份是否是当前年份。如果它们不相等，则调用函数 resetyear()。该函数被调用，但问题是功能无法正常工作。我正在对表格采取行动。但它没有采取该行动，也没有提交它。它只是发出警报直到“你好”。我的功能流程不会超出该警报。

请给我建议。

我的职能是 -

 function resetyear(){

if(confirm("DO YOU WANT TO RESET THE YEAR?"))
{
    alert("hello");
    var formname = document.getElementById("indexform");
    alert(formname);
    document.forms[0].action = "resetmaster";
    alert("hi")
    //alert(document.forms['indexform'].action);
    document.forms[0].submit();  
    alert("over");
    //form.action = "/resetmaster";
    //form.submit();
    alert(1);
}
else{

    alert("nothing");
}
}

  function dontreset()
{
alert("YOU CAN'T RESET THE YEAR");
}

和 HTML 代码是 -

 <html>
<head>
    <title>CHANDNA COLDSTORAGE</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <script src="js/calculateamt.js" type="text/javascript" ></script>
    <link href="CSS/style.css" rel="stylesheet" type="text/css">
    <script>
        function MM_goToURL() { //v3.0
            var i, args=MM_goToURL.arguments; document.MM_returnValue = false;
            for (i=0; i<(args.length-1); i+=2) eval(args[i]+".location='"+args[i+1]+"'");
        }
    </script>

</head>

<% String role = "";
    role = (String) session.getAttribute("role");

    String flag = "";
    flag = (String) session.getAttribute("flag");
    System.out.println("flag = " + flag);
    if (flag == null) {
        flag = "";
    }
    if (flag.equals("yes")) {

一个快速演示向我展示了所有警报：

JSFiddle

你确定这不是缓存问题吗？您可以尝试在 Chrome 或 Firefox 中调试您的 javascript 代码，看看发生了什么。

因为我有一个 JSFiddle 链接，所以我必须在此处包含一些代码。这是来自 JSFiddle 的代码：

<body>
    <script>
        function resetyear() {

            if (confirm("DO YOU WANT TO RESET THE YEAR?")) {
                alert("hello");
                var formname = document.getElementById("indexform");
                alert(formname);
                document.forms[0].action = "resetmaster";
                alert("hi")
                //alert(document.forms['indexform'].action);
                document.forms[0].submit();
                alert("over");
                //form.action = "/resetmaster";
                //form.submit();
                alert(1);
            } else {

                alert("nothing");
            }
        }
    </script>
