javascript - How do I get alternate style sheets to work on iOS5 Safari? -


i have been working on html5 app ipad. part of app includes using alternative style sheets. worked great on ios 4 safari , works fine on safari on desktop. however, upgraded 1 of our ipads ios 5 beta , no longer works. ideas?

here code this.

function (options) {     var i, a, main;     (i = 0; (a = document.getelementsbytagname("link")[i]); i++) {         if (a.rel.indexof("style") != -1         && a.title) {             a.disabled = true;             if (a.title == options.title) {                 a.disabled = false;                 console.log('the theme should changing : ' + a.title);                                 }         }

after searching , web, not happy of solutions. came new solution working in chrome, ff, ie , safari , safari on old ipad:

first set styles:

<link rel="stylesheet"              href="./codebase/touchui.css"       data-title="default"        type="text/css" media="screen" charset="utf-8"> <link rel="alternate stylesheet"    href="./codebase/ios.css"           data-title="ios"                type="text/css" media="screen" charset="utf-8"> <link rel="alternate stylesheet"    href="./codebase/jq.css"            data-title="jq"                 type="text/css" media="screen" charset="utf-8"> <link rel="alternate stylesheet"    href="./codebase/sky.css"           data-title="sky"                type="text/css" media="screen" charset="utf-8"> <link rel="alternate stylesheet"    href="./codebase/green.css"         data-title="green"          type="text/css" media="screen" charset="utf-8">

notice attribute "data-title" user-defined attribute.

then use function change style sheet, (note have set in app scope, can make standard function:

app = {}  app.styleset=function(title) {   var i,   var o;   for(i=0; (a = document.getelementsbytagname("link")[i]); i++)      if (a.getattribute("rel").indexof("style") != -1 && a.getattribute('data-title') ) {       if (a.getattribute('data-title') == title)          o =        a.setattribute("rel", "alternate stylesheet");        a.setattribute("title", a.getattribute('data-title'));       a.disabled = true   }    o.setattribute("title", undefined);    o.setattribute("rel", "stylesheet");    o.disabled = false   //app.cookiecreate("style", title, 365); }
