问题
I'm willing to use data tag as below.
<div data-color="#1337c"></div>
I use jquery to fetch($("div").data("color");) and store($("div").data("color", "red");) as well as manipulate data.
- Will IE7 support above tag ?
- What is the browser requirement for HTML5 ?
Thanks
回答1:
To answer the real question: jQuery.data works as expected in IE7 .. and IE6. (No HTML5 or official "data attribute" support required.)
IE7 will happily keep any attribute supplied in the HTML and expose it as such in the DOM. It doesn't matter if it is called data-foo or foo-data. I believe this is technically against the HTML4 specification, but it is the behavior of every major browser I know.
Do be aware, however, that data("foo") and attr("data-foo") have different semantics.

To my understanding, data attributes are not actually HTML5 features, but rather their use became standardized in HTML5. IE 5.5 (from what I remember) was actually the first browser to support pseudo attributes, but don't quote me on that :v
