jQuery添加自定义扩展

1、validate.js

//使用extend定义全局函数
$.extend({
    isUserName: function (value) {
        return new RegExp("/^[A-Za-z0-9\-\_\u4e00-\u9fa5]{2,20}$/").test(value)
    },
    isPassword: function (value) {
        return /(?!^(\d+|[a-zA-Z]+|[~!@#$%^&*?]+)$)^[\w~!@#$%^&*?]{8,16}$/.test(value);
    },
    isPassword1: function (value) {
        return new RegExp("(?!^(\d+|[a-zA-Z]+|[~!@#$%^&*?]+)$)^[\w~!@#$%^&*?]{8,16}$").test(value);
    },
    isEmail: function (value) {
        return new RegExp("^\\w+((-\\w+)|(\\.\\w+))*\\@[A-Za-z0-9]+((\\.|-)[A-Za-z0-9]+)*\\.[A-Za-z0-9]+$").test(value)
    },
    isDigits: function (value, required) {
        if (required == undefined || required == false) {
            return new RegExp(/^\d+$/).test(value);
        } else {
            if (value.trim().length > 0) {
                return new RegExp(/^\d+$/).test(value);
            } else {
                return "请输入数字";
            }
        }
    },
    isPhone: function (value) {
        //regexp_mobile = /^(13[0-9]|14[5|7]|15[0|1|2|3|5|6|7|8|9]|18[0-9]|17[0-9])\d{8}$/;  
        return new RegExp("^0?(13|15|18|14)[0-9]{9}$").test(value)
    },
    //加
    add: function (a, b) {
        var c, d, e;
        try {
            c = a.toString().split(".")[1].length;
        } catch (f) {
            c = 0;
        }
        try {
            d = b.toString().split(".")[1].length;
        } catch (f) {
            d = 0;
        }
        return e = Math.pow(10, Math.max(c, d)), (mul(a, e) + mul(b, e)) / e;
    },
    //减
    sub: function (a, b) {
        var c, d, e;
        try {
            c = a.toString().split(".")[1].length;
        } catch (f) {
            c = 0;
        }
        try {
            d = b.toString().split(".")[1].length;
        } catch (f) {
            d = 0;
        }
        return e = Math.pow(10, Math.max(c, d)), (mul(a, e) - mul(b, e)) / e;
    },
    //乘
    mul: function (a, b) {
        var c = 0,
            d = a.toString(),
            e = b.toString();
        try {
            c += d.split(".")[1].length;
        } catch (f) { }
        try {
            c += e.split(".")[1].length;
        } catch (f) { }
        return Number(d.replace(".", "")) * Number(e.replace(".", "")) / Math.pow(10, c);
    },
    //除
    division: function (a, b) {
        var c, d, e = 0,
            f = 0;
        try {
            e = a.toString().split(".")[1].length;
        } catch (g) { }
        try {
            f = b.toString().split(".")[1].length;
        } catch (g) { }
        return c = Number(a.toString().replace(".", "")), d = Number(b.toString().replace(".", "")), this.mul(c / d, Math.pow(10, f - e));
    }
});

2、validateObject.js

(function($){
   $.fn.extend({          
       alertWhileClick:function() {            
             $(this).click(function(){                 
                    alert($(this).val());           
              });           
        }       
   });

   $.fn.isDigits = function () {
      return new RegExp(/^\d+$/).test($(this).val());
   }
})(jQuery)

3、html页面引入validate.js文件
