這是演示代碼:如何獲得其存儲在jquery.data所有數據()
$(document).ready(function(){
$("button").click(function(e) {
var value;
switch ($("button").index(this)) {
case 0 :
value = $("div").data("blah");
break;
case 1 :
$("div").data("blah", "hello");
value = "Stored!";
break;
case 2 :
$("div").data("blah", 86);
value = "Stored!";
break;
case 3 :
$("div").removeData("blah");
value = "Removed!";
break;
}
$("span").text("" + value);
});
});
</script>
<style>
div { margin:5px; background:yellow; }
button { margin:5px; font-size:14px; }
p { margin:5px; color:blue; }
span { color:red; }
</style>
<div>A div</div>
<button>Get "blah" from the div</button>
<button>Set "blah" to "hello"</button>
<button>Set "blah" to 86</button>
<button>Remove "blah" from the div</button>
<p>The "blah" value of this div is <span>?</span></p>
但是,如何讓所有的數據(因爲一些關鍵的名字我不知道)?
