推荐答案
要测试您的服务器是否已启动,您需要连接到它并检查状态消息:
To test if your server is up you will need to connect to it and check status massage:
$.ajax('LINK GOES HERE', {
statusCode: {
404: function() {
alert('Not working');
},
200: function() {
alert('Working');
}
}
});

Working jsFiddle example: http://jsfiddle.net/Gajotres/PMrDn/47/
$.ajax({url: "http://api.themoviedb.org/2.1/Movie.search/en/json/23afca60ebf72f8d88cdcae2c4f31866/The Goonies",
dataType: "jsonp",
statusCode: {
200: function (response) {
alert('status 200');
},
404: function (response) {
alert('status 404 ');
}
}
});
使用这个:
$.ajax({url: "http://192.168.12.171",
type: "HEAD",
timeout:1000,
statusCode: {
200: function (response) {
alert('Working!');
},
400: function (response) {
alert('Not working!');
},
0: function (response) {
alert('Not working!');
}
}
});
