How can I create JavaScript created using document.write () to execute?

I have a multi-frame layout. One of the frames contains a form that I submit via XMLHttpRequest. Now when I use document.write () to rewrite the frame with the form, and the new page I add contains any javascript, then javascript will not be explicated in IE6?

For instance:

document.write("<html><head><script>alert(1);</script></head><body>test</body></html>");

In the above case, the content of the page is replaced by a test, but alert () is not executed. This works fine in Firefox.

What is the workaround for this problem?

In short: you cannot do this. However, JavaScript libraries such as jQuery provide functionality to do just that. If you are dependent on this, give jQuery a try.

Eval and / or running scripts dynamically is bad practice. Very bad practice. Very, very, very bad practice. I cannot stress how bad the practice is.

AKA .: Sounds bad design. What problem are you trying to solve again?

You can use the onload attribute in the body ( <body onload="jsWrittenLoaded()">) tag .
