I want to add a javascript in my wordpress blog site, as a new page. I have got the code, just tell me how to add it. It is an url opener script.
Create a new page, paste the code in the page? Or create a new template page, use the code there (paste it into the tamplate page file) and use the template page as the basis for the new WP-page?
All you need is here (http://codex.wordpress.org/Using_Javascript) Remark: JavaScript cannot be added to post content without a special WordPress Plugin that removes the filters that prevent unwanted code within the post content area, for the protection of the user.
If you want to use javascript on all the pages, then you can make a .js file and then include it in the footer of the theme. Or if you don't want to include javascript in all the pages than you can create a template, you will get it here (http://codex.wordpress.org/Page_Templates#Creating_a_Page_Template) And then write your JS code in it and select that template for the Page in which you want to include javascript.
