$.post and $. Ajax sends requests to the background on the page, requesting data

1.post because post defaults to asynchronous requests, but sometimes we find that requests appear immediately, but async causes a sudden execution later, so there are a lot of problems

2.Ajax the most primitive Ajax, can control synchronous or asynchronous, properties: Async set to False, for synchronization; Async is set to True, which represents asynchronous
The syntax is as follows:
$.ajax ({
Type: "Post",
URL: "Register/registerstate",
Data: "test=" + test,
Async:false,
Success:function (data) {
data = eval ("(" + Data + ")");
Adataset = data;
}
});
