Before doing project, use a table control, its data is loaded asynchronously, I am in this table binding the data of the function below friends do some business processing, run the page, the browser in my write business processing that place hit the breakpoint tracking, it did execute, can finally show when its processing is covered, I was wondering, and I knew it was the table-binding function. But the time is tight, its function is encapsulation, did not go to specific tracking, directly let me that part of the business processing delay 200ms implementation, so good, this is a stupid method, but also an effective way, hehe.
Later looked at the document, looked up some information, in fact, the principle should be such:
All requests are asynchronous requests under the default settings. If you need to send a sync request, set this option to false. Note that the synchronization request will lock the browser and the user's other actions must wait for the request to complete before it can be executed.
Copy Code code as follows:
var temp;
$.ajax ({
Async:false,
Type: "POST",
Url:defaultPostData.url,
DataType: ' JSON ',
Success:function (data) {
Temp=data;
}
});
Alert (temp);
This AJAX request is a synchronous request, and alert (temp) is not executed until the return value is returned.
If Async is set to: true, the result that the AJAX request returns is not awaited, and the statement behind Ajax is executed directly.
