我有以下jquery不显眼的代码，但没有触发。
$.validator.unobtrusive.adapters.add('customvalidation', ['productname'], function (options) {
options.rules['customvalidation'] = { productname: options.params.productname };
});
$.validator.addMethod("customvalidation", function (value, element, param) {
alert(param.productname);
return false;
});
但上面的代码假设在按下按钮提交表单时显示警告。
