Question

我正在尝试提交使用JQuery创建的表单。但是，调用JQuery的.submit()方法会将我发送到具有正确URL的空白页面。手动前往创建的URL可以正常工作。

详细说明：

我有一些代码可以创建一个非常大的表单对象，它不会插入到页面的任何位置（javascript是通过coffeescript生成的，如果这有所不同的话）。代码从（私人）页面http://webzyme-devl.umms.med.umich.edu:8080/webMathematica/webZyme/create.jsp

调用

form = $("<form action='" + (window.location.protocol + '//' + window.location.host + window.location.pathname) + "' method='GET'>");
addField = function(name) {
    return form.append("<input type='text' name='" + name + "' value='" + ($("#" + name).val()) + "'>");
};
addCheckbox = function(name) {
    var el;
    el = $("<input type='checkbox' name='" + name + "'>");
    el.prop("checked", $("#" + name).prop("checked"));
    return form.append(el);
};
addNewCheckbox = function(name) {
    var el;
    el = $("<input type='checkbox' name='" + name + "'>");
    el.prop("checked", true);
    return form.append(el);
};

//This is followed by a a bunch of processing and
// calls to addField, addCheckbox, addNewCheckbox, and manual calls to form.append
//No other modifications are made to the form, and no events are assigned to it

根据Chrome和Firefox调试程序给出了以下表单（为了调试我已将表单设置为GET，尽管它实际上是POST）：

<form method="GET" action="http://webzyme-devl.umms.med.umich.edu:8080/webMathematica/webZyme/create.jsp">

然后我尝试提交表单：

form.submit()

我希望这会在表单生成的主页面中加载URL。它确实将地址栏中的值设置为正确的URL

但它只加载一个空页面，没有来自控制台的错误或指示已加载任何内容。但是，如果我直接前往URL（通过在地址栏中点击Return），请求将按预期发送并加载页面。我能够在多个浏览器中重复此行为

我的假设是，这是一个涉及我如何使用.submit()方法的问题，而不是服务器配置的问题，因为手动提交URL会按预期工作。但是，如果它有所不同，该站点使用webMathematica在JavaServer上运行，并且当到达空页面时，服务器不会生成任何错误日志。

看起来您正在使用get方法提交表单。我怀疑你的请求可能对get方法来说太长了，你可能会遇到一些客户端或服务器限制。

如果可能的话，我建议从GET切换到POST，以查看是否可以修复任何内容。还要检查您的Web服务器日志，看它是否可能抛出Request Too Long（414）错误。

如果您的get请求太长，有时字符串将被截断，这可能会导致目标脚本出错。

祝你好运。
