因为，您可以看到...当在任一表单中单击提交按钮时，预计会弹出模态。但是，当我单击“登录”表单中的“提交”按钮时，没有任何反应。我知道我犯了一些错误，因为它在几小时后工作正常然后我不知道我做错了什么，现在我的代码完全坏了。模态窗口用于显示加载微调器。在上面的代码中，您可以在每个表单中看到一个锚元素，分别带有文本Register和Login。我不知道是否有必要，但我会解释它的作用。我想隐藏登录表单并在单击“注册”链接时显示注册表单。注册表单也有一个按钮，其方式相同，隐藏自身并使登录表单处于可视状态。注册表单还有一个提交按钮，单击该按钮时会触发模态。
如上所述，单击“登录”表单中的“提交”按钮时，模式不会弹出。但是当我切换到注册表单并单击“提交”时，它会触发模态。更有趣的是，当我切换回Login表单并单击“提交”时，它还会按预期显示模式。简而言之，当URL更改为myfile.php？＃时，一切正常，但是当它是myfile.php或myfile.php？时，我无法从Login窗体的提交按钮触发Modal，而无需至少切换一次该窗体。

下面的代码将在按钮点击时启动模态窗口。
这不是使你的逻辑工作的代码，但这只会在按钮点击时弹出模态窗口。

花点时间提交表单并显示模态
你同时做同样的事情，先显示模态，然后提交表格
function myFunction()
{
setTimeout(function(){
$("#loginForm").submit(); // if you want
}, 2000);
return false;
