angular表单验证实例----可用的代码
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
