The ajax request the server did not return to the results, close the browser error problem-CodePudding

 $. Ajax ({
Url: the path + "/Article/UnionSearchNav", 
Type: "post", 
DataType: "json", 
ContentType: "application/json," 
Data: JSON. Stringify (conditionObj), 
Success: the function (data) {

This is the front request code;

 
@ RequestMapping ("/UnionSearchNav ") 
@ ResponseBody 
Public String UnionSearchNav (@ RequestBody SearchCondition condition) {
String STR=searchService. GetTotal (condition); 
Return the STR; 
}

This is the background processing code;
If a request, the background hasn't been processed to shut down the browser, when after the background processing will be submitted to the following error (processing time is about 5 s), how to solve?
