originalEvent
, which is the event object that the browser itself created. jQuery wraps this native event object with some useful methods and properties, but in some instances, you'll need to access the original event via event.originalEvent
for instance. This is especially useful for touch events on mobile devices and tablets.// 這是用滾輪放大縮小圖片 (此範例firefox不支援)
$("#imgProductBig").bind("mousewheel", function (ev) {
var delta = ev.originalEvent.wheelDelta > 0 ? 1 : -1;
if (delta > 0 && zoomValue < 150) {
zoomValue += 10;
}
else if (delta < 0 && zoomValue > 50) {
zoomValue -= 10;
}
$(this).css("zoom", zoomValue + '%');
return false;
});

以下兩個都是innerHTML
document.getElementById('testId').innerHTML = "我是之後文字";
$('#testId').html("我是之後文字");
以下兩個都是outerHTML
document.getElementById('testId').outerHTML = "<div id="我是原本Id">我是原本文字</div>";
$('#testId').replaceWith("<div id="我是原本Id">我是原本文字</div>");
但是有時候~我們並不是要取代~而是想單純得到html含標籤的內容~
$('#testId').clone().wrap('<div>').parent().html()
