简易表单验证插件

学习完一门语言时难免会有一些想法与激情来驱动我们开发，以下是本人为了学习所编写的轮子，即使别人写的再香，我也想构造一套自己的表单验证

使用

$("form.Evaluate").submit(function () {
	var ModelStr = VerifiForm.GetValue({ el: ".Evaluate", VModel: VModel });
        if (typeof ModelStr != "boolean") {
             // console.log(ModelStr)
            // ajax submit()
        })

模型

• Reg: { Action: null, Notice: "" } Action 可填写正则匹配方法，不需要写括号，如您在此之前定义好了可将方法写入，例：Reg: { Action: check, Notice: "请您输入正确的数据" } *

var VModel = [
	{
		FieldName: "NickName",
		FieldType: "input",
		PseudoClass: "",
		Required: true,
		Reg: { Action: null, Notice: "" },
		Notice: "请填入您的姓名"
	},
	{
		FieldName: "Sex",
		FieldType: "input",
		PseudoClass: ":checked",
		Required: true,
		Reg: { Action: null, Notice: "" },
		Notice: "请选择性别"
	},
	{
		FieldName: "MsgStr",
		FieldType: "textarea",
		PseudoClass: "",
		Required: true,
		Reg: { Action: null, Notice: "" },
		Notice: "请填入留言内容"
	}
];

简易提交表单核心插件代码

function isEmpty(obj) {
	if (typeof obj == "undefined" || obj == null || obj == "") {
		return true;
	} else {
		return false;
	}
}  
function GetElemValByForm(elemtype, selector) {
	var _val = "";
	switch (elemtype) {
		case "input":
			_val = selector.val();
			break;
		case "textarea":
			_val = selector.val();
			break;
		case "select":
			_val = selector.val();
			break;
	}
	return _val;
}  
var VerifiForm =
{
	GetValue: function (obj_new) {
		var default_obj = {
			el: "",
			VModel: []
		};
		//var last_obj = Object.assign({}, default_obj, obj_new);
		var last_obj = obj_new;
		var _this = $(last_obj.el);
		var model = {};
		for (var i = 0; i < last_obj.VModel.length; i++) {
			var obj = last_obj.VModel[i];
			console.log(obj.FieldName);
			var torclass = (obj.FieldType + "[name=" + obj.FieldName + "]" + obj.PseudoClass);
			var _val = GetElemValByForm(obj.FieldType, _this.find(torclass));
			if (obj.Required) {
				if (!isEmpty(_val)) {
					if (obj.Reg.Action != null) {
						if (!obj.Reg.Action(_val)) {
							//alert(obj.Reg.Notice, { icon: 5 });
                                                        alert(obj.Reg.Notice);
							return false;
						}
					}
				} else {
					//alert(obj.Notice, { icon: 5 });
                                        alert(obj.Notice);
					return false;
				}
			}
			model[obj.FieldName] = _val;
		}
		console.log(model);
		return model;
	}
};
