namespace header and footer button icons #1361

When I use a namespace the buttons in the header and footer doesn't show icons. If I remove the namespace so the buttons have data-icon instead of data-namespace-icon, then they show up. Also the theming of the buttons in pages with data-namespace-theme doesn't work.

This is with jqmobile 1.0 alpha 4

I can confirm that. Icons does not show up. It would be great to have test version of jquery mobile with name-spacing applied, so that its easier to confirm if its a real bug or something wrong in our code.

Have the same problem here with a4.
Just updated to a4.1, it is still only working without the namespaces.
The following attributes are not supporting namespaces in header and footer bars:

  • data-icon
  • data-iconpos
  • data-theme

The problem lies in the unary usage of $.fn.jqmData() in $.fn.buttonMarkup().
However, the behaviour of jqmData not to strip the namespace when called without arguments seems to be deliberate, what I gather from #196, so buttonMarkup() should probably use an alternate version that returns only the attributes in the specified namespace.
(I would argue for this to be the default behaviour of $.fn.jqmData(), though, since everything else can just use $

Here is a quick fix that I just wrote for 1.0a4, it works with jquery-1.6, previous versions don't return the attributes in camelCase, but that should be easily fixed.

$.fn.jqmData = function( prop, value ){
    var result = prop ? $.mobile.ns + prop : prop, value );
    if ($.mobile.ns && !prop) {
      var ccns = $.camelCase($.mobile.ns);
      var trailingDash = false;
      if (ccns && ccns.charAt(ccns.length-1) === "-") {
        trailingDash = true;
        ccns = ccns.substring(0, ccns.length-1);
      var strippedResult = {};
      for (var key in result) {
        if (key.indexOf(ccns) === 0) {
          var strippedKey;
          if (trailingDash) {
            strippedKey = key.charAt(ccns.length).toLowerCase() + key.substring(ccns.length+1);
          } else {
            strippedKey = key.substring(ccns.length);
          strippedResult[strippedKey] = result[key]; 
      return strippedResult;
    return result;
