问题
I would like to display a window in my webpage of another webpage, hopefully via iframe. I need to set the src as a javascript variable, here is the code:
<html>
<head><title>my webpage</title></head>
<SCRIPT language=JavaScript type=text/javascript>
function GoToURL(j) {
var URLis = document.URLframe.Dest.value
document.write("<center><iframe src=\"http://www.example.com\"/ width=1350 height=500 seamless></center>");
}
</SCRIPT>
<FORM name=URLframe>
<TABLE align=center border=0>
<TBODY>
<TR>
<TD vAlign=center align=middle><BR><INPUT maxLength=50 size=50
name=Dest></TD></TR>
<TR>
<TD align=middle>
<P><INPUT onclick=GoToURL(this) type=button value=" Go to.. " name="Go to"></P></TD></TR></TBODY></TABLE></FORM>
</html>
I need to set the iframe src to the variable URLis, simply put. I am somewhat of a newb in both html and javascript, so please keep as simple as possible. Do you have any suggestions or ideas for a way to set the iframe src as URLis variable?
Thank you.

Try this:
var URLis = document.URLframe.Dest.value;
document.write('<center><iframe src="' + URLis + '" width=1350 height=500 seamless></center>');
