formvalidator插件

一、引用jquery　　

二、引用formValidator.js

//====================================================================================================
// [插件名称] jQuery formValidator
//----------------------------------------------------------------------------------------------------
// [描    述] jQuery formValidator表单验证插件，它是基于jQuery类库，实现了js脚本于页面的分离。对一个表
//            单对象，你只需要写一行代码就可以轻松实现20种以上的脚本控制。现支持一个表单元素累加很多种
//            校验方式,采用配置信息的思想，而不是把信息写在表单元素上，能比较完美的实现ajax请求。

//显示漂浮显示层

    }
    return this.each(function()
    {
        jqobj = $(this);
        s = $("<span class='top' id=fv_content style='display:block'></span>");
        b = $("<b class='bottom' style='display:block' />");
        this.tooltip = $("<span class='fv_tooltip' style='display:block'></span>").append(s).append(b).css({"filter":"alpha(opacity:95)","KHTMLOpacity":"0.95","MozOpacity":"0.95","opacity":"0.95"});
        //注册事件
        jqobj.bind({
            mouseover : function(e){
                $("#fvtt").append(this.tooltip);
                $("#fv_content").html(this.Tooltip);
                $.formValidator.localTooltip(e);
            },
            mouseout : function(){
                $("#fvtt").empty();
            },
            mousemove: function(e){
                $("#fv_content").html(this.Tooltip);
                $.formValidator.localTooltip(e);
            }
        });
    });
}

})(jQuery);

三、初始化验证组$.formValidator.initConfig();

validationgroup用户设置验证分组，可以通过设置分组号，在需要时验证指定分组。

onerror:验证未通过时提示信息。

  $.formValidator.initConfig({ validatorGroup: "2", onError: function (msg) { alert(msg) } });

四、设置验证规则：

 $("#diyunique_work_days").formValidator({ validatorGroup: "2", onShow: "请输入天数", onFocus: "天数最小为1", onCorrect: "正确"}).inputValidator({ type: "number", min: 1, max: 1000, onError: "工期必须是大于1小于1000的数字" }).regexValidator({ regExp: "^\d+$", param: "g", onError: "天数必须是大于1小于1000的数字" });

$.formValidator.initConfig({ validatorGroup: "5", onError: function (msg) { alert(msg) } });
                    $("#order_open_proxy_account").formValidator({ validatorGroup: "5", onShow: "请输入代理账号信息", onFocus: "请输入代理账号信息", onCorrect: "正确"}).inputValidator({ type: "size", min: 6, max: 20, onError: "代理账号长度在6-20之间" }).ajaxValidator({
                        url:"/OrderManage/IsExistsEmployee",
                        type:"post",
                        dataType:"json",
                        data:{name:$("#order_open_proxy_account").val()},
                        async:false,
                        success:function(data){
                            if(data.exists){
                                return true;
                            }else{
                                return true;
                            }
                        }
                    });

五、调用验证。

通过$.formValidator.pageIsValid("a"),a指前面validationgroup设置的分组号。

 //表单验证
                                if($.formValidator.pageIsValid('5')){
                                    return true;
                                }else{
                                    return false;
                                }
