Javascript implementation method _ javascript tips for small discovery in the Flash activation box does not appear in IE

We all know that the method of deceiving IE from Flash activation box is simple as long as a js file is introduced on the page, then, use js to control the html code output of flash. However, if our script is dynamically loaded, there will be two situations. See the following code:


Program code
Var s = docuemnt. createElement ("script ");
S. src = src;
Docuemnt. getElementsByTagName ("head") [0]. appendChild (s );



Program code
Var s = docuemnt. createElement ("script ");
Docuemnt. getElementsByTagName ("head") [0]. appendChild (s );
S. src = src;


At a glance, the execution results of these two broken codes are similar. However, there is a piece of code that cannot fool IE, and the imported js output flash will show an activation box.

The only difference between the two disconnections is to assign a value to the src of the script object and append it to the head. Or append first and then assign a value. I did an experiment. I only need to assign a value to the src of the script and append it to the page to cheat IE.
