小编Shi*_*hel的帖子

在进行ajax调用时,请参阅下面的示例,success确实会重新调整201状态.你如何更好地处理这些成功函数中的200,201？

$.ajax({
    type: "POST",
    dataType: "json",
    url: "http://api.domain.com/sms",
    data: {
      // Send value in mobile input field.
      mobile: $("#mobile").val(),
    },
    // On successful AJAX call do the following.
    success: function(data) {
      $('#messageText').text('SMS successfully sent');
    },
    error: function(jqXhr) {
      data = JSON.parse(jqXhr.responseText);
    }
});

当我在本地运行测试时，我收到了下面提到的Ember 项目的ember test错误消息。大部分时间 PhantomJS 都挂着。

$ ember test

是否有任何替代navigator.permissions.query 权限API查询，以检查geolocation许可。导致其仍在工作草案中，并且浏览器兼容性较差。

W3C权限参考： https : //www.w3.org/TR/permissions/

问题是，app resume一旦用户对本机权限弹出窗口执行操作，然后要检查action用户是否采取了该措施。

混合式Cordova应用回调，用于位置权限警报

平台：移动Android

注意：不想使用cordova diagnostic plugin

例：

navigator.permissions.query({name:'geolocation'}).then(function(result) {

  console.log('result : ', result);

});
