Archdeacon Posted June 19, 2009 Share Posted June 19, 2009 I am very new to javascript (but have had years writing VBScript) and wouldlike to know how to accomplish the following (I cant use ActiveX as this willnot work in Firefox):1. When the user clicks on a link to a web page, assign the source code of that page to a variable before extracting certain values using a Regex (that is not a problem).2. Assign those values to an environment variable so that they are retained if the page is closed but picked up when the page is refreshed.3. Delete the environment variable only when the browser is closed. Link to comment Share on other sites More sharing options...
Synook Posted June 19, 2009 Share Posted June 19, 2009 For internal links, you can use AJAX to get the target's content (1). Then you can use cookies to store the values (2) (however cookies have a size limit, you may be better off just storing the URL and retrieving the content every time). However you can't operate session cookies in JavaScript (3) so you may just have t oset a short timeout for the cookies.To fetch the source of external pages or to use sessions you need the help of a server-side language.
