JQuery插件，轻量级表单模型验证（续 二）

好不容易，有心思，那就把没做完的JQuery轻量级表单验证做完吧

之前做到了空参数验证的，现在增加带参数的验证。

附上html

<form id="ValidataForm">
    <input type="number" data-required="true" data-name="数字范围" data-type="required|Range:10,15" value="">
    <button id="Send">提交</button>
</form>

一个很常见的输入框，输入框是数字类型，必填，范围是10到15之间

之前框架的实现修改了一下，原来eq是JQuery对象，JavaScript自带的Array是没有eq方法的，改了一通，代码附上

var validateForm = (function(model) {
    model.Key = "[data-required='true']";
    model.ElementList = new Array();
    model.FunctionDictionary = new Dictionary();
    model.ToastrCustom = function (msg) {
        alert(msg);
    }

    model.AddElement = function (name) {
        model.ElementList.push(name);
    };

    model.AddFunction = function (name, func) {
        model.FunctionDictionary.add(name, func);
    };

    model.Validate = function (formName) {
        for (var i = 0; i < model.ElementList.length; i++) {
            var thisObj = model.ElementList[i];
            var str = formName + " " + thisObj + model.Key;
            var elements = $(str);

            for (var j = 0; j < elements.length; j++) {
                var element = elements.eq(j);
                var value = element.val();

                var elementType = element.data().type;

                if (elementType.indexOf("|") > -1) {
                    var splitStrs = elementType.split("|");

                    for (var index in splitStrs) {
                        var splitStr = splitStrs[index];
                        var find = model.FunctionDictionary.contains(splitStr);

                        if (find) {
                            if (splitStr.indexOf(":") > -1) {
                                var params = splitStr.split(":");

                                var func = model.FunctionDictionary.find(params[0]);
                                if (func) {
                                    var result = func(value, element, params[1]);

                                    if (result.status) {
                                        var errorInfo = result.message;
                                        model.ToastrCustom(errorInfo);
                                        return;
                                    }
                                }
                            }
                            else {
                                var func = model.FunctionDictionary.find(splitStr);
                                if (func) {
                                    var result = func(value, element);

                                    if (result.status) {
                                        var errorInfo = result.message;
                                        model.ToastrCustom(errorInfo);
                                        return;
                                    }
                                }
                            }
                        }
                    }
                }
                else {
                    var func = model.FunctionDictionary.find(elementType);
                    if (func) {
                        var result = func(value, element);

                        if (result.status) {
                            var errorInfo = result.message;
                            model.ToastrCustom(errorInfo);
                            return;
                        }
                    }
                }
            }
        }
    };

    model.ElementList.push("input");
    model.ElementList.push("select");
    model.FunctionDictionary.add("required", function (value, element) {
        var name = element.data().name;

        return {
            status: (value === ""),
            message: (value === "" && name + "不能为空")
        };
    });

    return model;
})(window.validateForm || {});

扩展了一个方法

validateForm.AddFunction("Range", function (value, element, params) {
    var name = element.data().name;
    try {
        var items = params.split(",");

        if (items.length != 2) {
            return {
                status: false,
                message: name + " 验证格式不对"
            };
        }

        var min = new Number(items[0]);
        var max = new Number(items[1]);
        var valueNum = new Number(value);

        var check = (min < max) && (min < valueNum && valueNum < max);
        return {
            status: check,
            message: (check && name + " 范围不对")
        };
    } catch (error) {
        console.log(error);
        return {
            status: false,
            message: error.message
        };
    }
});
