The function get_wxh ()

The console. The log (hdfWxh);

} 

How is this execution sequence backwards, the output is empty,

CodePudding user response:

Actually very simple, you can directly in the callback function calls to functions that you need not to go, the code is as follows:

 
//in the variables, but in other js code on a page called 
Var hdfWxh; 
Var hdfWxhName; 
Var hdfWxhSex; 
Window. _hdf. Callback=function (data) {
/* * 
* get WeChat ID information js variable, and assign a value to a custom global variable 
*/
HdfWxh=data. WXH;//WeChat ID 
HdfWxhName=data. Wxh_name;//WeChat ID name 
HdfWxhSex=data. Wxh_sex;//gender 
Get_wxh (hdfWxh); 
}; 

The function get_wxh (WXH) 
{
The console. The log (hdfWxh); 
$(' zaax WXH - '). Attr (' id ', '22222'); 
}

Get_wxh this method did not trigger
You the section of code defines the method just didn't call

The callback execution inside get_wxh ()
