js代碼(除了指令意外,沒什麼可用的,寫出來只是爲了,說一下mvc模式而已!)css

var app = angular.module("angularFormCheckModule",[]);

/*這裏使用MVC的模式(用來舉例說明MVC而已)*/
app.controller("angularFormCheckCtrl",function($scope,angularFormCheckFactory){//function裏的參數寫你在函數裏須要用到的
    $scope.testVar = angularFormCheckFactory.getTest();//這裏就能取到$scope.testVar的值爲---"練習angular表單校驗";
    
    $scope.user = {};
    
    $scope.test= "sss";
    
});


/*本身能夠去看factory、service、providers的區別(http://www.oschina.net/translate/angularjs-factory-vs-service-vs-provider)*/
/*用 Factory 就是建立一個對象,爲它添加屬性,而後把這個對象返回出來。*/
app.factory('angularFormCheckFactory',function(){
    //這裏寫本身的業務邏輯
    var test = "練習angular表單校驗";
    var service = {};//自定義一個對象
    
    service.getTest = function(){//給對象添加方法
        return test;
    }
    
    return service;//返回自定義的service對象!!!
});

/*自定義指令--比較兩個密碼是否相等.angular的指令是駝峯的形式(這裏是comparePwd頁面就是compare-pwd)*/
app.directive('comparePwd',function(){
    /*angular 自定義指令,可上網自行查找*/
    return{
        require : 'ngModel',
        /*scope表示做用域,elem表示使用這個指令的元素對象(這裏指第二個密碼框),attrs。。。ctrl。。。*/
        link : function(scope,elem,attrs,ctrl){
            /*寫本身的業務邏輯*/
            //注意這樣取值的話,第一密碼框的Id值必需要設置且必須與第二個密碼框的compare-pwd屬性的值相同
            var firstPwdIdObj = "#" + attrs.comparePwd;
            $(elem).add(firstPwdIdObj).on('keyup',function(){
                /*手動執行髒檢查*/
                scope.$apply(function(){
                    //$(firstPwdIdObj).val()表示第一個密碼框的值。elem.val()表示第二個密碼框的值
                    var flag = elem.val() === $(firstPwdIdObj).val();
                    //alert(flag+",--"+elem.val()+",--"+$(firstPwdIdObj).val());
                    ctrl.$setValidity("pwdmatch",flag);//flag,表示是否相等。pwdmatch用於$error時的標識符,注意看頁面,$setValidity是require中ngModel的方法!
                });
            });
        }
    }
});

很差意思今天才知道這個能夠添加代碼,以前寫的博客代碼都好醜,沒有對齊(。。。哈哈,鄉下來的!!!)html
