This depends on what you're trying to do:

If you had a list of URLs you want to show one after the other you could use an iframe to display that URL and use javascript to change the url periodically.

If you don't want to redirect between pages, the best option is to use AJAX technology.

And again completely depend on your requirement, like if you to run multiple pages parallel, you can use stuff like , tags.

Dear Volker Mauel,

Thank you very much, Excellent, Fantastic.

I would be most thankful if you could give me the code when my URL is as a Loop. For example:

var URLs = ["http://www.abcd.com/index.php?id=$x"];

$x is variable.

you could simply iterate over the different variables and keep the base url the same

var baseUrl = "http://www.abcd.com/index.php?id=";

for(var id=0;id
