Bootstarp風格的toggle效果分享
編輯：關於JavaScript
最近在寫項目的時候想要一個這樣的效果，
我知道這個效果在 flat-ui中有， 但是我又不想引用一整個flat-ui;
這個效果依賴html5的transition， 所以浏覽器兼容成問題；
從flat-ui中把這個效果的js和html，以及css給撥離出來；
整體的代碼如下：
運行下面代碼

//toggle插件的js代碼
var toggleHandler = function(toggle) {
var toggle = toggle;
var radio = $(toggle).find("input");
var checkToggleState = function() {
if (radio.eq(0).is(":checked")) {
$(toggle).removeClass("toggle-off");
} else {
$(toggle).addClass("toggle-off");
}
};
checkToggleState();
radio.eq(0).click(function() {
$(toggle).toggleClass("toggle-off");
});
radio.eq(1).click(function() {
$(toggle).toggleClass("toggle-off");
});
};
$(".toggle").each(function(index, toggle) {
toggleHandler(toggle);
});
</script>
</body>
</html>
整體的效果是依賴於jQuery， 當用戶點擊了label按鈕會觸發input的click事件， 然後判斷給父級添加不同的classname；
