How to decomment an html/php webpage?

- by Sam

A crazy question: Imagine a webpage file called somepage.php And it contains some html php contents in my editor I see: <html><head></head><body> <?=$welcome . $essay . $thatsAllForNowFolks . $footer ?>  </body></html> When I browse my site I see those comments in the final result, while I only want that comment to be only in my editor for my secretive inspirations and don't want the whole world to know what I'm thinking when I'm developing, as well as I see those comments for any and all my website visitors as wasted bandwitch of internet speed. How do I decomment my entire html/php files at the moment the html is served? Ideas, code and suggestions are much appreciated. My thanks in advance...

git, how to I go back to origin master after pulling a branch

- by fishtoprecords

This has to be a FAQ, but I can't find it googling. Another person created a branch, commit'd to it, and pushed it to github using git push origin newbranch I successfully pulled it down using git pull origin newbranch Now, I want to go back to the origin master version. Nothing I do seems to cause the files in the origin master to replace those in the newbranch. git checkout master git checkout origin master git pull git pull origin HEAD etc git pull origin master returns: * branch master -> FETCH_HEAD Already up-to-date. This can't be hard, but I sure can't figure it out. 'git branch' returns * master and 'git branch -r' return origin/HEAD origin/experimental origin/master

IE not blocking javascript

- by Corey Hart

It seems that IE8 defers javascript, but also doesn't block. I've setup a test environment to prove this. Here's the html page(replace 192.168.1.xxx with your server): <html> <head> <title>IE Pains</title> <script type='text/javascript' src='http://192.168.1.xxx/ietest/js.js'></script> <script type='text/javascript'> scream('hello world'); </script> </head> <body> </body> </html> And the js File: function scream( str ) { alert( str ); } Am I seeing this wrong, or does IE not recognize the scream function because it hasn't finished loading js.js?

google maps clicking inside a polygon

- by amarsh-anand

The following javascript snippet is supposed to do the following: As the user clicks on the map, initialize headMarker and draw a circle (polygon) around it As the user clicks inside the circle, initialize tailMarker and draw the path between these two markers 1 is happening as expected. But as the user clicks inside the circle, overlay is non-null while point is null in the function(overlay,point) . Can someone tell me a way out. GEvent.addListener(map, "click", function(overlay,point) { if (isCreateHeadPoint) { // add the head marker headMarker = new GMarker(point,{icon:redIcon,title:'0'}); map.addOverlay(headMarker); isCreateHeadPoint = false; // draw the circle drawMapCircle(point.lat(),point.lng(),1,'#cc0000',2,0.8,'#0',0.1); } else { // add the tail marker tailMarker = new GMarker(point,{icon:greenIcon,title:''}); map.addOverlay(tailMarker); isCreateHeadPoint = true; // load thes path from head to tail direction.load("from:" + headMarker.getPoint().lat()+ ", " + headMarker.getPoint().lng()+ " to:" + tailMarker.getPoint().lat() + "," + tailMarker.getPoint().lng(), {getPolyline:true}); } });

iOS - playing a youtube video from a webview thumbnail

- by soleil

Was about to finally submit an app when I realized that the youtube videos I'm playing play from the iPhone, but not the iPad. Here's the code I'm using: NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, [videoItem objectForKey:@"URL"], thumb.frame.size.width, thumb.frame.size.height]; UIWebView *videoView = [[UIWebView alloc] initWithFrame:thumb.frame]; [videoView loadHTMLString:html baseURL:nil]; [videoContainer addSubview:videoView]; Is there any reason this would work on the iPhone and not the iPad? I'm testing on a 1st generation iPad. The videos play on both iPhone models I've tested (3GS and 4S). Nothing happens at all when I tap on the webviews on the iPad.

How to properly preload images, js and css files?

- by Kenny Bones

Hi, I'm creating a website from scratch and I was really into this in the late 90's but the web has changed alot since then! And I'm more of a designer so when I started putting this site together, I basically did a system of php includes to make the site more "dynamic" When you first visit the site, you'll be presented to a logon screen, if you're not already logged on (cookies). If you're not logged on, a page called access.php is introdused. I thought I'd preload the most heavy images at this point. So that when the user is done logging on, the images are already cached. And this is working as I want. But I still notice that the biggest image still isn't rendered immediatly anyway. So it's seems kinda pointless. All of this has made me rethink how the site is structured and how scripts and css files are loaded. Using FireBug and YSlow with Firefox I see a few pointers like expires headers and reducing the size of each script. But is this really the culprit? For example, would this be really really stupid in the main index.php? The entire site is basically structured like this <?php require("dbconnect.php"); ?> <?php include ("head.php"); ?> And below this is basically just the body and the content of the site. Head.php however consists of the doctype, head portions, linking of two css style sheets, jQuery library, jQuery validation engine, Cufon and Cufon font file, and then the small Cufon.Replace snippet. The rest of the body comes with the index.php file, but at the bottom of this again is an include of a file called "footer.php" which basically consists of loading of a couple of jsLoader scripts and a slidepanel and then a js function. All of this makes the end page source look like a typical complete webpage, but I'm wondering if any of you can see immediatly that "this is really really stupid" and "don't do that, do this instead" etc. :) Are includes a bad way to go? This site is also pretty image intensive and I can probably do a little more optimization. But I don't think that's its the primary culprit. YSlow gives me a report of what takes up the most space: doc(1) - 5.8K js(5) - 198.7K css(2) - 5.6K cssimage(8) - 634.7K image(6) - 110.8K I know it looks like it's cssimage(8) that weighs the most, but I've already preloaded these images from before and it doesn't really affect the rendering.

Jquery mobile page structure

- by Die 20

I built a jquery mobile site a while back and I have recently been expanding on it and noticing performance issues. I believe it is because I constructed the site using a multi-page set up where a single php file houses the following pages: **ALL_PAGES.PHP** <html> <head> /* external css and js files */ </head> <body> <div date-role="page" id="main"> <div class="page_link"> page 1 </div> <div class="page_link"> page 2 </div> <div class="page_link"> page 3 </div> </div> <div date-role="page" id="page 1"> <div class="page_link"> main </div> <div class="page_link"> page 2 </div> <div class="page_link"> page 3 </div> </div> <div date-role="page" id="page 2"> <div class="page_link"> main </div> <div class="page_link"> page 1 </div> <div class="page_link"> page 3 </div> </div> <div date-role="page" id="page 3"> <div class="page_link"> main </div> <div class="page_link"> page 1 </div> <div class="page_link"> page 2 </div> </div> </body> </html> **end ALL_PAGES.PHP ** I want to break away from this multi-page setup on one php file, and move to a setup where each page is a separate php file. To accomplish this I took the html from each page and moved it to its own php page. Then I added href links in replace of the mobile.change() functions I used for the "page_link" classes. **MAIN.PHP** <html> <head> external css and js files </head> <body> <div date-role="page" id="page 1"> <a href="/main.php"> main </a> <a href="/page_2.php"> page 2 </a> <a href="/page_3.php"> page 3 </a> </div> </body> </html> **end MAIN.PHP** **PAGE_1.PHP** <div date-role="page" id="page 1"> <a href="/main.php"> main </a> <a href="/page_2.php"> page 2 </a> <a href="/page_3.php"> page 3 </a> </div> **end PAGE_1.PHP** **PAGE_2.PHP** <div date-role="page" id="page 2"> <a href="/main.php"> main </a> <a href="/page_1.php"> page 1 </a> <a href="/page_3.php"> page 3 </a> </div> **end PAGE_2.PHP** **PAGE_3.PHP** <div date-role="page" id="page 3"> <a href="/main.php"> main </a> <a href="/page_1.php"> page 1 </a> <a href="/page_2.php"> page 2 </a> </div> **end PAGE_3.PHP** The site works fine except when the user hits the refresh button in the browser. When that happens each page loses access to any external css and js files located on the main page. I am fairly new to JQM so any advice would be helpful.
