COMPLETE list of HTML tag attributes which have a URL value? -

-

besides following, there html tag attributes have url value?

  • href attribute on tags: <link>, <a>, <area>
  • src attribute on tags: <img>, <iframe>, <frame>, <embed>, <script>, <input>
  • action attribute on tags: <form>
  • data attribute on tags: <object>

looking tags in wide usage, including non-standard tags , old browsers html 4.01, html 5, , xhtml.

check out w3c's list of html attributes, there's "type" column in there , uri types.

and of course html 5 version of list useful too

so html4 we've got:

  • <a href=url>
  • <applet codebase=url>
  • <area href=url>
  • <base href=url>
  • <blockquote cite=url>
  • <body background=url>
  • <del cite=url>
  • <form action=url>
  • <frame longdesc=url> , <frame src=url>
  • <head profile=url>
  • <iframe longdesc=url> , <iframe src=url>
  • <img longdesc=url> , <img src=url> , <img usemap=url>
  • <input src=url> , <input usemap=url>
  • <ins cite=url>
  • <link href=url>
  • <object classid=url> , <object codebase=url> , <object data=url> , <object usemap=url>
  • <q cite=url>
  • <script src=url>

html 5 adds few (and html5 seems not use of ones above well):

  • <audio src=url>
  • <button formaction=url>
  • <command icon=url>
  • <embed src=url>
  • <html manifest=url>
  • <input formaction=url>
  • <source src=url>
  • <track src=url>
  • <video poster=url> , <video src=url>

these aren't simple urls:

  • <img srcset="url1 resolution1 url2 resolution2">
  • <source srcset="url1 resolution1 url2 resolution2">
  • <object archive=url> or <object archive="url1 url2 url3">
  • <applet archive=url> or <applet archive=url1,url2,url3>
  • <meta http-equiv="refresh" content="seconds; url">

svgs can contain links resources: <svg><image href="url" /></svg>

in addition, style attribute can contain css declarations 1 or several urls. example: <div style="background: url(image.png)">

(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...

(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."
