Why ajax need refresh to add nodes-CodePudding

 $(function () {
$. Ajax ({
Type: "get",//request 
Url: "IndexHello",//send the request address 
Async: true,//
//sent to the server data 
DataType: "json",//the server returns the data type of the 
Success: function (date) {//request after the completion of the call of the callback function, no matter success or failure, 
If (date. Islogin=="1") {
Var username=date. The username; 
$(" # helllogin "). Append (" & lt; li>  " ); 
} else {
$(" # helllogin "). Append (" & lt; li>  " ); 
} 
} 
}) 
});

As shown in figure need to refresh the page to show the login button, or the username in json, this how to solve

CodePudding user response:

Async: true this default is asynchronous,

The console. The log (date. Islogin) print and see what's in the under value,

CodePudding user response:

Ajax asynchronous apis, such as response will appear, see the browser console information, or write a debugger to debug in success,

CodePudding user response:

You send a synchronous request, that is, to refresh a guy, asynchronous to support local refresh, sometimes I have to cancel the default behavior
