我使用的是这里答案中提供的fiddle中的以下JS代码：
如何在Tooltipster工具提示中显示来自jQueryValidate插件的消息？
小提琴在这儿：http://jsfiddle.net/kyK4G/
错误显示在第36行，即：submitHandler：演示的函数（表单）｛//
这就是错误：
TypeError: $(...).validate is not a function
submitHandler: function (form) { // for demo
代码：
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
$(document).ready(function () {
// initialize tooltipster on text input elements
$('#myform input[type="text"]').tooltipster({
trigger: 'custom',
onlyOne: false,
position: 'right'
});
// initialize validate plugin on the form
$('#myform').validate({
errorPlacement: function (error, element) {
$(element).tooltipster('update', $(error).text());
$(element).tooltipster('show');
},
success: function (label, element) {
$(element).tooltipster('hide');
},
rules: {
field1: {
required: true,
email: true
},
field2: {
required: true,
minlength: 5
}
},
submitHandler: function (form) { // for demo
alert('valid form');
return false;
}
});
});

听起来页面上没有验证插件脚本：
http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js
看起来您没有包含提供.validate()方法的jQuery插件。您应该将其包含在jQuery:之后
<script src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js"><script>
一般来说，如果你有一个对象，你可以尝试使用点符号访问不同的属性，如下所示：
var myAwesomeObject = {
coolProperty: "whooooa!"
, coolMethod: function() {return this;}
};
myAwesomeObject.coolProperty; // "whooooa!"
myAwesomeObject.coolMethod; // function(){return this;}
如果属性恰好是一个方法，您可以将其称为：
myAwesomeObject.coolMethod(); // Object {coolProperty: ...
如果您试图访问的属性在对象上不存在，您将返回undefined
myAwesomeObject.missingProperty; // undefined
由于undefined不是一个函数，尝试将丢失的属性作为方法进行调用将导致您看到的错误：
myAwesomeObject.missingMethod(); // TypeError: you messed up.
我也遇到了这个问题。我用另一种方法解决了这个问题。我在文件中得到的
要解决这个问题，必须声明一个特定的类。使用
mfp-TYPE CSS类（其中TYPE是所需的内容类型）。例如：<a class="mfp-image image-link">Open image</a>, $('.image-link').magnificPopup().
另一个例子：<a class="mfp-iframe video-link">Open Video</a>, $('.video-link').magnificPopup().
