You can directly use something like this
你可以直接使用这样的东西
$('#button1').click(function(){
$('#search').submit();
});
Or you can use it from any javascript code. Which will trigger your $('#myForm').submit(function(){.....function code.
或者您可以从任何 javascript 代码中使用它。这将触发您的$('#myForm').submit(function(){.....功能代码。

return false;
adding this to function will stop the form submitting.
将此添加到函数将停止提交表单。
Or if you want to call function on a different event put the function in an appropriate event handler (a non-submit button's click?)
或者，如果您想在不同的事件上调用函数，请将函数放在适当的事件处理程序中（非提交按钮的点击？）

You will have to dig it from DOM data. But, let me tell you, its not recommended. Try this,
您将不得不从 DOM 数据中挖掘它。但是，让我告诉你，它不推荐。尝试这个，
var form = $('#myForm');
var data = form.data();
var events = data.events;
If the handler function is attached to form 'submit', it will be present as,
如果处理程序函数附加到表单“提交”，它将显示为，
var submit_list = events.submit;
Now, if all goes well, at best you can get submit_listas list of all the handler objects attached to submit event of form.
现在，如果一切顺利，您最多可以获得submit_list附加到表单提交事件的所有处理程序对象的列表。
Shortcut:Assuming you have one and only one handler attached to submit event for #myForm,
快捷方式：假设您有一个且只有一个处理程序附加到提交事件#myForm，
$('#myForm').data().events.submit[0].handler
is your function.
是你的功能。
Play with data(), but remember its not recommended. Happy Coding.
玩data()，但记住它不推荐。快乐编码。

Extract code from callback to function and call it when it is needed.
从回调函数中提取代码并在需要时调用它。
