angular表单验证实例----可用的代码

标签:reset   transform   eth   通过   har   strong   imp   detail   section   

前段时间,公司做一个单页面,就是一个表单验证,早开始在菜鸟教程上关注了angular,所以下派上用场了

angular里面对于表单验证,设置了很多指令。

也就是说不用自己写一些逻辑,直接绑定指令就行。

ng-app     启动你angular的模块

 ng-controller 控制器,启动你angualr里面的逻辑代码作用在页面上

ng-options  循环你select里面的option标签,很好用的

 ng-submit,表单提交执行的

novalidate  表单form配合后期检测的

ng-model  实现双数据绑定

ng-show 根据一定的逻辑实现显示

ng-cloak 绑定在节点上,防止节点渲染,angular指令闪烁

ng-class class类名根据你的逻辑,出现

ng-required 检测你的input为不为空

ng-pattern 正则表达式,绑定在input上面限制输入规范

ng-maxlength 最多输入限制

ng-minlength 最少输入限制

ng-disabled="myForm.$invalid" 脏检测

大概就需要这些指令了,大家不要喷我。谢谢

下面开始上代码了,说一下呀

LArea.js是一个移动端地址三联动弹出框,我就不解释了、、、、、、、、、、、、、、、、、、、
jquery其实和angualr没有关系,主要是配合LArea.js使用

下面是js文件了

var app=angular.module("myapp",[]);
app.controller(‘gift‘,function($scope,$http){
   $scope.dates=[
    "一院",
    "四院",
    "五院",
    "六院",
    "七院"
   ];
   $scope.save = function () {
        var myselect=document.getElementById("company");
        var index=myselect.selectedIndex ; 
        var companyVal=myselect.options[index].value;
        var companyText=myselect.options[index].text;
        //获取到表单是否验证通过
        if($scope.myForm.$valid){
            var datajson = {
                userName:$scope.userName,
                mobile:$scope.mobile,
                address:$scope.address,
                detaileDaddress:$scope.detaileDaddress,
                postcode:$scope.postcode,
                companyVal:companyVal,
                companyText:companyText
            }   
            console.log(datajson);
            
       /* $http({
            method  : ‘POST‘,
            url     : ‘‘,
            params    : pData,  
            headers : { ‘Content-Type‘: ‘application/x-www-form-urlencoded‘ } 
        })
        .success(function(data) {
           alert(‘表单通过‘);
        });*/

        }else{
            alert(‘表单没有通过验证‘);
        }
    }
});

解释下

$http({
            method  : ‘POST‘,
            url     : ‘‘,
            params    : pData,  
            headers : { ‘Content-Type‘: ‘application/x-www-form-urlencoded‘ } 
        })
        .success(function(data) {
           alert(‘表单通过‘);
        });
和jquery的$.ajax一样,和后台交互的
 if($scope.myForm.$valid){
            var datajson = {
                userName:$scope.userName,
                mobile:$scope.mobile,
                address:$scope.address,
                detaileDaddress:$scope.detaileDaddress,
                postcode:$scope.postcode,
                companyVal:companyVal,
                companyText:companyText
            } 
$scope.你节点上的ng-model里面的数据
这样能获取到你input里面的内容

css部分我就不说了

这种写法其实不优化,主要体现出提示上,重复的节点出现多,在项目中尽量模板简洁,不要出现重复的节点,反正我看起来很刺眼。。。。

下面我会把节点封装起来,把提示判断写在js逻辑里面,我觉得是一个优化的写法,大神不要喷我
