提交jquery之前验证表单

问题描述：

我有一个html表单.我正在使用jquery.validate.js验证表单，并且可以在Submit事件上使用.我想在提交被解雇之前验证此表单.

I have a html form. i am validating my form using jquery.validate.js and it works on submit event. I want to validate this form before submit get fired.

根据我的R& D，我已经尝试过:

As per my R&D i have tried :

$('#my-form').on('before-submit',function(){
   alert('Before submit performed');
});

我想在触发提交事件之前验证表单. 谁能告诉我该怎么做?

I want to validate form Just before firing submit event. Can any one tell me how to do this?

非常感谢，

您可以模仿默认的jQuery插件行为，如下所示:

You can mimic the default jQuery plugin behaviour as follows:

测试form是否有效；如果不能防止使用preventDefault()进行默认操作:

Test if the form is valid; if not prevent the default action from occurring using preventDefault():

$(document)
.on('click', 'form button[type=submit]', function(e) {
    var isValid = $(e.target).parents('form').isValid();
    if(!isValid) {
      e.preventDefault(); //prevent the default action
    }
});

编辑:如果您想微调验证测试(即有条件地验证某些控件)，这将非常有用.

EDIT: this comes in handy if you want to fine-tune your validation test i.e. validating some controls conditionally.
