How are the events outside the temp?

 $(function () {
Var temp=""; 
$(" # sort "). Change (function () {
Var temp=$(this). Val (); 
}); 

The console. The log (" I value "+ temp); 
}); 

CodePudding user response:

Only after the change event has been triggered temp assignment,
And the console. The log (" I value "+ temp); Is performed before the change event trigger, the temp haven't be assignment,

CodePudding user response:

The console must be executed in again after change event has been triggered. The log (" I value "+ temp); Only

 
$(function () {
Var temp=""; 
$(" # sort "). Change (function () {
Temp=$(this). Val (); 
(aa); 
}); 
The function (aa) {
The console. The log (" I value "+ temp); 
} 
});
