rururu2211785113的博客通过本文主要向大家介绍了ajax请求 angularjs-ht等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
1.ajax请求：
mui.plusReady(function() {
var self = plus.webview.currentWebview();
for(var i = 0; i < 5; i++) {
var temp = {};
var sub = plus.webview.create(subpages[i], subpages[i], subpage_style);
if(i > 0) {
sub.hide();
} else {
temp[subpages[i]] = "true";
mui.extend(aniShow, temp);
}
self.append(sub);
}
plus.runtime.getProperty(plus.runtime.appid, function(inf) {
wgtVer = inf.version;
var _config = {
url: 'http://60.30.254.100:8035/'
// url: 'http://192.168.1.108:8080/'
}
var checkUrl = _config.url + "version/compareVersionIndexMain.action";
var data = {
"appversion": wgtVer,
"id": "3"
}
$.ajax({
type: "POST",
url: checkUrl,
dataType: "json",
data: {
ds: JSON.stringify(data)
},
success: function(data) {
if(data.success == "0"){
alert("已有新版本，请更新");
}else if(data.success == "1"){
}
},
error: function(e) {
return;
}
});
});
});
注意：
第一点：plus-api代码要写在plus-ready之后
第二点：ajax请求要用JSON.stringify转一下，返回的数据data.success是String数据，与0或者1比较要用==
java后台代码：
@RequestMapping("/compareVersionIndexMain")
public void compareVersionIndexMain(HttpServletRequest req, HttpServletResponse res)
throws UnsupportedEncodingException {
req.setCharacterEncoding("utf-8");
System.out.println("AAAAAAAAAAAA");
String ds = req.getParameter("ds");
System.out.println("ds==="+ds);
JSONObject json = JSONObject.fromObject(ds);
System.out.println("解析后的json数据===" + json.toString());
String appversion = json.getString("appversion");
String id = json.getString("id");
JSONObject jsonObject = new JSONObject();
if (id != null && appversion != null) {
Version version = dao.getVersionById(Integer.parseInt(id));
if (Float.parseFloat(appversion) < Float.parseFloat(version
.getV_num())) {
jsonObject.put("success", "0");
jsonObject.put("url", version.getUrl());
} else {
jsonObject.put("success", "1");
}
} else {
jsonObject.put("success", "-1");
}
System.out.println("首页检查更新返回的数据==="+jsonObject.toString());
returnResponse(res, jsonObject.toString());
}

2.angular js使用http请求：
<html ng-app="mine_main">
<body class="mui-fullscreen" ng-controller="LSControllerForMineMain">
ng-model---变量名
ng-app---整体
ng-controller---控制器
ng-init---初始化
var app = angular.module('mine_main', []);
app.controller('LSControllerForMineMain', function($scope, $location, $http) {
//alert(JSON.parse(localStorage.getItem("userInfo")).realname);
$scope.realname = localStorage.getItem("realname");
$scope.data = null;
var wgtVer = null;
$http({
method: 'POST',
url: LSHelper.getInstance().getValue('baseurl') + '/respection_problems/getRoleName.action',
header: {
'Content-Type': 'application/x-www-form-urlencoded',
'Cookie': LSHelper.getInstance().getValue('sessionid')
}
}).then(function successCallback(response) {
//alert(JSON.stringify(response));
if(response.data.success == 1) {
$scope.roleName = response.data.data;
} else {
alert("error,code:" + response.data.success);
}
}, function errorCallback(response) {
alert("error");
});
$scope.updateVersion = function() {
// alert("更新版本");
// 获取本地应用资源版本号
plus.runtime.getProperty(plus.runtime.appid, function(inf) {
wgtVer = inf.version;
// alert("当前应用版本：" + wgtVer);
});
if(wgtVer != null) {
var _config = {
url: 'http://60.30.254.100:8035/'
// url: 'http://192.168.1.108:8080/'
}
var checkUrl = _config.url + "version/compareVersion.action"
plus.nativeUI.showWaiting("检测
