我正在尝试在bootstrap popover中显示验证错误消息，如此问题中所述：
How to use Twitter Bootstrap popovers for jQuery validation notifications?
但由于某些原因，我的代码无效。
这是我的代码：

答案 0 :(得分：1)
您的代码来自the jsFiddle ...
$("#idCompanyReg").validate({
name: {
required: true,
minlength: 5,
maxlength: 15
},
...
},
您的规则必须在rules选项的内。
$("#idCompanyReg").validate({
rules: { // <-- you need the rules option here
name: {
required: true,
minlength: 5,
maxlength: 15
},
...
},
至少jsFiddle现在正在运作：http://jsfiddle.net/3qYpM/420/
