• 如何创建AnjularJS项目


    第一步:命名空间
    var applyAppModule=angular.module('apply-app' ,[]); 
     
    第二步:控制器 ng-controller="ApplyController"
    applyAppModule.controller('ApplyController', function($scope,$http){
     
    });
    第三步:监听器  //ng-click="change($index)"
    applyAppModule.controller('ApplyController', function($scope,$http){
         $scope.change= function(index){ 
                httpStatus($scope.items[index]);
         }
    });
    第四步:过滤器  //ng-bind="item.status|status_filter"
    applyAppModule.filter( "status_filter", function() {
                       var filterfun = function(code) {
                             var result = "";
                               ........
                             return result;
                      };
           return filterfun;
    });
     
    第五步:http请求
     
    AngularJS 提供了一个类似jquery的$.ajax的对象,用于异步请求。
    在AngularJS中对异步操作是推崇至极的,所以$http的操作都是异步的不像jquery.ajax里还提供了async参数。
     
     如果你是POST请求,params里的数据会帮你拼到url后面,data里的数据会放到请求体中。
     
    /* http start */
    
    $http({
                method : 'POST',
                url : "/MobileMedical/suser/applylist",  //请求地址
                data :$.param({                           //携带数据
                  "offset":0,
                   "limit":6
                      }),
                headers : {
                       'Content-Type' : 'application/x-www-form-urlencoded'
                }
          }).success( function(response) {
                 if (response.rows != "") {
                      $scope.items = response.rows;
                      initPagination($scope, $http, response.total, LIMIT);
                } else {
                      alert( '查询列表为空' );
                }
          });
    /* http end */

    或者这种格式:

       $http({
          method : 'POST',
          params : { id:123}, 
          data:  { name:'john',age:27 }, 
          url : "/mypath"
        })
        .success(function(response, status, headers, config){
             //do anything what you want;
        })
        .error(function(response, status, headers, config){
             //do  anything what you want;
        });
