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; });
实例:
(1)html部分 : index.html

(2)javascript部分 : indexCtrl.js
//实例化命名空间 var app=angular.module('indexApp' ,['paginationAPP']); //取cookie中的用户信息 var userObj = $.cookie('userObj' ); //json字符串 var userObj = JSON.parse(userObj); //对象 app.controller('indexCtrl', function($scope,$http){ //将用户信息存入$scope中 $scope.userObj = userObj; // 初始化页面数据 init({ pId:userObj.cid }); // 监听搜索框 keyup事件 $scope.onKeyup = function(e){ var keycode = window.event?e.keyCode:e.which; if(keycode==13){ //重新请求 init({ pId:userObj.cid, search:$scope.search.keyword }); } } //监听搜索按钮的ng-click事件 $scope.toSearch=function(){ var search=$scope.search; var params={ pId:userObj.cid, search:search.keyword }; init(params); //重新请求 } //监听 ng-click事件,查看详情 $scope.seemore=function(index){ var obj=$scope.result.list[index]; //对象转成json字符串,存入cookie var appObj= JSON.stringify(obj); $.cookie( 'appObj' , appObj , { path : "/" }); window.location.href="/SocialManage/page/info"; } //初始化方法 function init(params){ $http({ method : 'GET', params :params, url : "/SocialManage/api/appInfo/getList" }) .success(function(response, status, headers, config){ $("#loading").hide(); console.log("back indexController ...."); console.log(response); $scope.result=response; $scope.paginationConf.totalItems=response.count; }) .error(function(response, status, headers, config){ }); } }); // 过滤器 app.filter( "user_img_filter", function() { //用户头像 过滤器 var filterfun = function(code) { if(!codem || code==""){ return "/images/logo.png"; }else{ return code; } }; return filterfun; }).filter("ms_filter", function() { //毫秒转时间 过滤器 var filterfun = function(code) { var result = new Date(parseInt(code)).toLocaleString(); return result; }; return filterfun; }).filter( "text_filter", function() { //文字长度 过滤器 var filterfun = function(code) { var result = code.length > 20 ? code.substr(0,20) :code; return result; }; return filterfun; });
