方法一：
複製代碼代碼如下:
<script type=”text/javascript”>
var obj = new Image();
obj.src = “yourpicurl.jpg”;
obj.onload = function() { //這個地方可以重複寫入，如果錯誤的話，換到外面即可
document.getElementById(”mypic”).innnerHTML = “<img src='”+this.src+”' />”;
}
</script>
<div id=”mypic”>onloading……</div>
方法二：
複製代碼代碼如下:
<script type=”text/javascript”>
var obj = new Image();
obj.src = “yourpicurl.jpg”;
obj.onreadystatechange = function() {
if ( this.readyState == “complete”) { //這個地方可以重複寫入，如果錯誤的話，換到外面即可
document.getElementById(”mypic”).innnerHTML = “<img src='”+this.src+”' />”;
}
}
</script>
<div id=”mypic”>onloading……</div>
