I hope it will be helpful for you to answer the doubt that "the ajax in jquery returns results rather than callbacks, that is, the method tutorial is executed in the same order"!

Because the default ajax is asynchronous, that is, it does not affect downward execution when the result is not responded to. Therefore, it must be realized by callback. This scheme is more efficient.
If you do not want to return a result, change the parameter async in ajax to false, which will be executed in the same order. You can return the result by implementing the following.
However, this practice is not recommended when it is not necessary.
The copy code is as follows:
Function (url,params) {
Var outdata
$.ajax ({
Type: "get"
Async:false
DataType: "json"
Url: url
Data: params
Success: function (data) {
Outdata = data
}
Error:function (e) {
Alert ('ajax error')
}
});
Return outdata
}
