Creating a custom rule in jQuery Validate
提问by Jason Wells
I would like to add a custom rule to jQuery validate, and while I have checked the docs I have not been able to find out how to do this.
我想向 jQuery 验证添加自定义规则，虽然我已经检查了文档，但我无法找到如何执行此操作。
I want to loop over a set of hidden form fields. If the fields value is "X", then I would like to append an error class to a field.
我想遍历一组隐藏的表单字段。如果字段值为“X”，那么我想将错误类附加到字段。
So essentially this, but added as a rule to jQuery validate.
所以本质上是这样，但作为规则添加到 jQuery 验证中。
$(".myHiddenField").each( function() {
if($(this).val() == "x") {
$(this).closest(".foo").appendClass("error");
}
});

You may use addMethod()
您可以使用 addMethod()
$.validator.addMethod('yourRuleName', function (value, element, param) {
//Your Validation Here
return isValid; // return bool here if valid or not.
}, 'Your error message!');
$('#myform').validate({
rules: {
field1: {
yourRuleName: true
}
}
});

If you want to show some custom error messages without adding an actual rule then you can use the showErrors()method, but if you are working on a hidden field it may not work
如果您想在不添加实际规则的情况下显示一些自定义错误消息，则可以使用showErrors()方法，但如果您正在处理隐藏字段，则它可能不起作用
var validator = $( "<form-selector>" ).validate();
var errors = {};
$(".myHiddenField").each( function() {
var $this = $(this);
if($this.val() == "x") {
errors[$this.attr('name')] = 'Some error message';
}
});
validator.showErrors(errors);

$.validator.addMethod("NOTx", function(element,value) {
return value != "x";
}, 'warning word"!');
