/********************************************************************* REFRAME.JS Re-loads any frame content page into the appropriate frame of the appropriate frameset document. To both frameset and frame content documents, add the following entry: Based on sample code by Th. H. Smith; generalized by RNE, 2002-10-02. If the browser opens a frame content document, the script generates a composed URL like http://www.domain.com/index.html?contentFrame=http://www.domain.com/pages/page.html sends it to the browser, the browser opens the frameset file http://www.domain.com/index.html and the script again says to change the content of 'contentFrame' to the file http://www.domain.com/pages/page.html Easy, isn't it? Feel free to use this code as base for your own JS experiments; but I can't give you any warranty... ;-) *********************************************************************/ /* reFrame() Call from the frameset document as follows: Arguments: defaultTargetFrame should be a valid frame object (not name!) of the current window. */ function reFrame(defaultTargetFrame) { // Init, & make sure our frameset is the top frameset var myURL = self.location.href; if (top.location.href != myURL) { top.location.href = myURL; } // Examinate the URL var p1 = myURL.indexOf("?"); if (p1 > 0) { // if any '?' was found // Init var var newFrameLoc = ""; var targetFrame = defaultTargetFrame; // just copy default, change later if possible // Get target frame var p2 = myURL.indexOf("=", p1); // start search at p1 ('?') if (p2 <= p1) { // no target information found newFrameLoc = myURL.substring(p1+1, myURL.length); } else { newFrameLoc = myURL.substring(p2+1, myURL.length); var targetFrameName = myURL.substring(p1+1, p2); for (i=0; i < self.frames.length; i++) { if (parent.frames[i].name == targetFrameName) { targetFrame = parent.frames[i]; break; } // if no matching frame was found, targetFrame is still = defaultTargetFrame } } // Change target frame content, if possible if ((targetFrame != null) && (newFrameLoc.length > 0)) { // To avoid flicker, we compare URLs first & change only if necessary: if (newFrameLoc != targetFrame.location.href) { // Change as necessary targetFrame.location.href = newFrameLoc; } } } // if (i > 0) -- else: do nothing, URL is simplex (w/o any '?') } /* loadIntoFrame() Call from any frame content document as follows: Arguments: targetFrameName (as string) should be the name of the corresponding target frame as defined in the tag of the frameset document. relPathToFramesetDoc (as string) should be the relative path to the frameset document */ function loadIntoFrame(targetFrameName, relPathToFramesetDoc) { // Are we already framed correctly? var frameName = window.name; if (frameName == targetFrameName) { // It's fine! return; } // Test the URL: avoid loops! var myURL = top.location.href; var pos = myURL.indexOf("?"); if (pos > -1) { // Would result in an URL with multiple occs of '?' -- error! return; } // Test frames var myParent = window.parent; if (myParent != null) { if (myParent.frames.length > 0 ) { // If we are multiply framed, lets not get stuck in a loop! return; } } // Finally, do the change pos = myURL.lastIndexOf("/"); if (pos > -1) { var parentDirURL = myURL.substring(0, pos+1); top.location.href = parentDirURL + relPathToFramesetDoc + "?" + targetFrameName + "=" + myURL; // Something like 'http://www.x.de/pages/../index.html' is no problem! // The HTTP protocol resolves it into the correct absolute adress! } // Else: error, do nothing! } /********************************************************************* EOF *********************************************************************/
