------ Solution --------------------
No. PHP is the server-side language and JS is the browser-side language. Apache first executes the PHP code, parses it into HTML code, downloads it to the user's browser, and then executes the JS language for further rendering. So when your code runs PHP first, and then TOP. api, it is disconnected from apache when it is executed to script document. write (abc) and script.

The upstairs is correct. use AJAX !!!

TOP. api ('rest', 'get ',{
  
// Method: 'Taobao. taobake. items. convert ',
  
Method: 'Taobao. taobake. widget. items. convert ',
  
Num_iids :'
  ',
  
Fields: 'Num _ iid, click_url, commission_rate'
  
}, Function (resp ){
  
If (resp. error_response ){
  
Alert ('Taobao. taobake. widget. items. convert interface failed to get commodity information! '+ Resp. error_response.msg );
  
Return false;
  
}
  

  
Var respItem = resp. taobaoke_items.taobaoke_item;
  
For (var I = 0; I <respItem. length; I ++ ){
  
Abc = respItem [I]. num_iid;
  
}
  
$. Post ('', {abc: abc}, function (data) {}) // add an ajax request here
  
})
  
Script
  

  If (isset ($ _ POST ['ABC'])
  
{
  
$ Abc = $ _ POST ['ABC'];
  
Echo $ abc;
  
}
  
?>
  

 

You can use ajax to modify your code.
------ Solution --------------------
In fact, data obtained from the client through js can be submitted through an event-driven approach. one is ajax, and the other is to trigger the submission when certain conditions are met, for example, through setTimeout, if certain conditions are met, submit is triggered. In short, it can meet the needs of lz.
