如何在angularjs中调用sync和async？

Question

我想在 angularjs 中自定义同步和异步，如下所示。

  var async = function (url, data, action, callback) {   
        $.ajax({
            url: global.baseURL + url,
            type: action,
            data: data,                
            async: true,//or false
            success: function (data) {
                if (data !== undefined && data !== null) {
                    callback(data);
                }
            }
        });
    };

在AngularJs中看起来像这样的代码

 $http({ method: 'GET', url: baseURL + 'Api/MobilePref/Get/'+uid
        })
        .success(function (data, status, headers, config) {
        })
        .error(function (data, status, headers, config) {
            //TODO: handl error.
        });

谁能告诉我如何在 angularjs 中设置同步和异步调用？

你可以这样做：

function callAjax(url, callback){
    var xmlhttp;

    xmlhttp = new XMLHttpRequest();
    xmlhttp.onreadystatechange = function(){
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200){
            callback(xmlhttp.responseText);
        }
    }
    xmlhttp.open("GET", url, true); // the flag true tell if this is async or not and then you can call $scope.$apply for angular to know.
    xmlhttp.send();
}
