how to detect that browser is going to issue a write command

[lily ling]

Hi, there

I know we can use document.write() to print any contents on page but how to know that browser is going to use this command before/while it starts to do printing. Is there any way to detect that what command browser is going to execute ?

Thank you very much, any advice is highly appreciated.

document.write happensa s the page is being rendered? I am not sure what you are trying to do.

I would like to know if we can capture document.write() command that browser is going to execute to print the page so I can add some other logic.

unless you can write an if statement around it, then no....

Not sure what are you trying todo...
Have you tried something like:

 
document.oldWrite = document.write;
document.write=function(str){
    // do something here
 
   document.oldWrite(str);
 
   // do something else
 
}
 

So, whenever the page will try to call document.write (after your function definition, so put it at the begining of the page), your code will be called.
