var app = angular.module("myApp", []);
app.controller("myController", function ($scope, $http) {
$scope.search = function () {
var result = $http({
method: "get",
url: "../api/home/get",
params: {
"id": $scope.demoKey
}
});
result.then(function successCallBack(response) {
$scope.names = response.data;
alert("请求成功");
}, function errorCallBack(response) {
alert("请求失败");
});
};
});
</script>
调试的时候names已经有值了，为什么页面还是空白的？

为什么菜鸟教程上面就不需要手动刷新
@灬丶: $scope.$apply();//需要手动刷新我贴的代码有啊
@s_p: 关键是我使用$scope.$apply()然后调试时页面浏览器就提示错误了，这个需要引用别的angular库？
@灬丶: 检查错误啊 你复制我的代码保存为html 运行 查看效果。代码、运行效果、图片 。详细说明都贴了网址。。
