html - Cross Browser Issue -

-

my background in winforms programming , i'm trying branch out bit. i'm finding cross-browser issues frustrating barrier in general, have specific 1 can't seem work through.

i want display image , place semi-transparent bar across top , bottom. isn't ultimate goal, of course, demonstrates problem i'm having in relatively short, self-contained, code fragment let's go it.

the sample code below displays intended in chrome, safari, , firefox. in ie8, bar @ bottom doesn't appear @ all. i've researched hours can't seem come solution.

i'm sure dumb rookie mistake, gotta start somewhere. code snippet...

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript" language="javascript"> </script> <style type="text/css">     .workarea     {         position: relative;         border: 1px solid black;         background-color: #ccc;         overflow: hidden;         cursor: move;         -moz-user-focus: normal;         -moz-user-select: none;         unselectable: on;     }      .semitransparent     {         filter: alpha(opacity=70);         -moz-opacity: 0.7;         -khtml-opacity: 0.7;         opacity: 0.7;         background-color: gray;     } </style> </head> <body style="width: 800px; height: 600px;"> <div id="workarea" class="workarea" style="width: 800px; height: 350px;     left: 100px; top: 50px; background-color: white; border: 1px solid black;">     <img alt="" src="images/testimage.jpg" style="left: 0px; top: 0px; border: none;         z-index: 1;" />     <div id="topbar" class="semitransparent" style="position: absolute;width: 800px;         height: 75px; left: 0px; top: 0px; min-height: 75px; border: none; z-index: 2;" />     <div id="bottombar" class="semitransparent" style="position: absolute; width: 800px;         height: 75px; left: 0px; top: 275px; min-height: 75px; border: none; z-index: 2;" /> </div> </body> </html>

you self-closing div tag, not allowed self-closed.

you must close div tag this: </div>.

some browsers support stupid mistakes these, , attempt close tags you. ie, on other hand, doesn't.

try this:

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript" language="javascript"> </script> <style type="text/css">     .workarea     {         position: relative;         border: 1px solid black;         background-color: #ccc;         overflow: hidden;         cursor: move;         -moz-user-focus: normal;         -moz-user-select: none;         unselectable: on;     }      .semitransparent     {         filter: alpha(opacity=70);         -moz-opacity: 0.7;         -khtml-opacity: 0.7;         opacity: 0.7;         background-color: gray;     } </style> </head> <body style="width: 800px; height: 600px;"> <div id="workarea" class="workarea" style="width: 800px; height: 350px;     left: 100px; top: 50px; background-color: white; border: 1px solid black;">     <img alt="" src="images/testimage.jpg" style="left: 0px; top: 0px; border: none;         z-index: 1;" />     <div id="topbar" class="semitransparent" style="position: absolute;width: 800px;         height: 75px; left: 0px; top: 0px; min-height: 75px; border: none; z-index: 2;" ></div>     <div id="bottombar" class="semitransparent" style="position: absolute; width: 800px;         height: 75px; left: 0px; top: 275px; min-height: 75px; border: none; z-index: 2;"></div> </div> </body> </html>

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
