推荐答案
要测试你的服务器是否启动,你需要连接到它并检查状态按摩:
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');
}
}
});

Use this:

type: "HEAD",
timeout:1000,
statusCode: {
200: function (response) {
alert('Working!');
