Add :data() Selector

[kaneiderdaniel@…]

Provide a selector for .data(), similar to those of attributes:

Example with attributes

• $("".someClass[myAttr])
• $("".someClass[myAttr='someValue'])

Likewise something for .data

• $("".someClass:hasData(myAttr))
• $("".someClass:data(myAttr='someValue'))

You can avoid the need for this, if you use custom data attributes, as and only as DOM attributes: <div id=""test"" data-test=""value""></div> .. $(""#test[data-test='value'])

But if you start using the .data() function, this is no longer possible in such a way: <div id=""test""></div> .. $(""#test"").data(""test"", ""value"") $(""#test[data-test='value']) fails

Alternative: $(""*"").filter(function() { return $(this).data(""test"") === ""value""; });

There is a already a plugin which implements this problem, which I would like to see included in $1.7 in some way...  http://plugins.jquery.com/project/dataSelector

[jaubourg]

-1, well, use the plugin

[timmywil]

-1, best as plugin

[paul.irish]

probably a better written plugin:  http://james.padolsey.com/javascript/a-better-data-selector-for-jquery/

[dmethvin]

-1, No new selectors.

[john]

-1, Plugin.

-1, Not only no new selectors, I feel like this is a particularly bad way to query the DOM generally. There's a :data selector baked into jQuery UI, if you want to use it.  https://github.com/jquery/jquery-ui/blob/master/ui/jquery.ui.core.js#L206

-1, there are so many things you might or might not want this selector to handle

Closing per 1.7 roadmap meeting resolution
