jQuery显示表单警报框 [英] jQuery display form alert box

问题描述

我正在尝试显示一个警报或可设置样式的弹出框，当按下提交"按钮时，该框会显示空字段".添加alert("Empty Fields!!");

Hi i'm trying to display an alert or style-able popup box that says Empty Fields when the submit button is press. The code below stopped working after I added alert("Empty Fields!!");

var validator = $("#reg_form").validate({
    errorLabelContainer: $("#reg_form div.error"),
    meta: "validate",
    alert("Empty Fields!!");
});

推荐答案

我假设 http://docs.jquery.com/Plugins/Validation/validate 是您的代码所引用的jQuery插件.

I assume that http://docs.jquery.com/Plugins/Validation/validate is the jQuery plugin that your code referes to.

您不能在类声明中使用警报.您将必须像这样重写它:

You can't use alert in class declaration. You will have to rewrite it like this:

var validator = $("#reg_form").validate({
    errorLabelContainer: $("#reg_form div.error"),
    meta: "validate",
    submitHandler: function( form ) {
        alert("Empty Fields!!");
    }
});

或使用invalidHandler:function(form，validator)代替SubmitHandler

or use invalidHandler: function(form, validator) instead of submitHandler
