In the smarty template, js modifies the value of the form, as it directly uses this form value in the template for if statement judgment

In the smarty template, js modifies the form value. if this form value is directly used in the template for if statement judgment? Code: & lt; script & nbsp; language = "javascript" & gt; function & nbsp; handlerTao (tao, yitaocan, huafei) {& nbsp; in the & nbsp smarty template, js modifies the form value. if this form value is directly used in the template for the if statement judgment?
Code:

 
  
function handlerTao(tao,yitaocan,huafei){
  
            $("#taocan").val(tao);
  
$("#taocanid").val(huafei);
  
}
  
《script》  
  

  
   

   

  
 

Now the form value with id taocanid has been dynamically added to jquery.

Now we want to use this value for the if statement judgment. What should I do? Shared to: function? HandlerTao (tao, yitaocan, huafei ){???????????? $... 'Data-pics = ''>

Where do you want to judge the if statement ??
