jQuery Validation plugin custom method. Multiple parameters
提问by BuzzBubba
I'm trying to use a custom validator with jQuery Validation plugin. However, I'm unsure how are you supposed to pass multiple arguments to a validation method? I've tried using (2,3), curly braces and combinations, but I have failed.
我正在尝试将自定义验证器与 jQuery 验证插件一起使用。但是，我不确定您应该如何将多个参数传递给验证方法？我试过使用 (2,3)、花括号和组合，但我失败了。
This is the code - ???? marks the area I need info about:
这是代码 - ???? 标记我需要有关以下信息的区域：
$(document).ready(function() {
jQuery.validator.addMethod("math", function(value, element, params) {
return this.optional(element) || value == params[0] + params[1];
}, jQuery.format("Please enter the correct value for {0} + {1}"));
$("#form_register").validate({
debug: true,
rules: {
inputEl: { required: true, math: ???? }
},
messages: {
inputEl: { required: "Required", math: "Incorrect result" }
}
});
});

Javascript arrays:
Javascript 数组：
[value1,value2,value3]
SO your code might be:
所以你的代码可能是：
inputEl: { required: true, math: [2, 3 ,4 , 5] }

You can also pass a normal JavaScript object as a parameter which I personally find easier to work with:
你也可以将一个普通的 JavaScript 对象作为参数传递，我个人认为它更容易使用：
jQuery.validator.addMethod("myRule", function (value, element, options) {
return value === options.data;
}, "My Rule says no!");
$("#input").rules("add", { myRule: { data: "foo" } });
