使用spin.js的jQuery submit（）阻止表单提交？

I have a form that submits just fine, but when I add jQuery code to show a loading div using spin.js everything stops working.

我有一个提交的表单很好,但是当我添加jQuery代码以使用spin.js显示加载div时,一切都停止工作。

<form id="search_form" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" method="POST">
<!-- Form inputs here -->
...
<input id="exam_search" type="submit" name="submit" value="Search" />   

Once I add the following code the form stops submitting and nothing happens. The loading div shows for a brief moment and then goes away like expected, but it seems like the form isn't actually submitting anymore.

一旦我添加以下代码,表单停止提交,没有任何反应。加载div显示一个短暂的时刻然后像预期的那样消失,但似乎表单实际上不再提交了。

var opts = // Array of options 
var spinner = null;
$("#search_form").submit(function() {
    spinner_div = document.getElementById('spinner');
    if(spinner == null) {
        spinner = new Spinner(opts).spin(spinner_div);
        $("#search_results, #query").css({"opacity": "0.75"});
        $("#search_form :input").attr("disabled", true);

    } else {
        spinner.spin(spinner_div);
        $("#search_results, #query").css({"opacity": "0.75"});
        $("#search_form :input").attr("disabled", true);
    }
});

If I change all of that code in the submit event to this:

如果我将提交事件中的所有代码更改为:

$("#search_form").submit(function() {
    alert ("form submitted");
});

It shows the alert and then returns the results of the form submission just fine.

它显示警报,然后返回表单提交的结果就好了。

What am I doing wrong here?

我在这做错了什么?

EDIT I saw in the jQuery docs for submit() that I shouldn't use the name "submit" on the input field. I tried changing that as well with no luck.

编辑我在jQuery docs中看到了submit(),我不应该在输入字段中使用名称“submit”。我试着改变它,没有运气。

Well I'm not sure why but simply doing this worked:

嗯,我不确定为什么,但只是这样做:

$("#search_form").submit(function() {
    var spinner_div = document.getElementById('spinner');
    var spinner = new Spinner(opts);
    spinner.spin(spinner_div);
});
