Two Methods for JS Printing

You can click the "print" button to print the page out. JS usually has two methods.

1. Print with Object

Add object

 
 

  
  
<objectIDobjectID=WebBrowser1WIDTH="0"HEIGHT="0" 
  
  
CLASSID=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2> 
  
  
</object> 
 
 

Add the following JS functions:

 
 

  
  
<scripttypescripttype="text/javascript"> 
  
  
functionprint()  
  
  
{  
  
  
document.getElementById(WebBrowser1).ExecWB(6,1);  
  
  
}  
  
  
</script> 
  
  
 
 
 

Add print button: <ahref = "javascript: print ();"> print </a>

2. Use JS built-in function Printing

 
 

  
  
<Ahrefahref = "javascript: window. print ();"> print </a>
  
  
 
 
 

In fact, the first method is also a complex implementation method of the second method, but the first method provides more features such as previewing and modifying print settings.
The second method is recommended. For security reasons, some browsers, such as roaming, disable some objects. Therefore, the first method reports JS errors with insufficient permissions during roaming.
