问题描述
我有以下SWF：
<head>
# load js
<script>
function graph() {
swfobject.embedSWF(
"open-flash-chart.swf", "chart", "400", "180", "9.0.0", "expressInstall.swf",
{"data-file":"{% url monitor-graph %}"});
};
</script></head>
<div id="chart"> </div>
<script>
graph();
</script>
我想只在swf尚未加载的情况下调用图形函数，是否有这样做的方法？谢谢。
I would like to call the graph function only if the swf has not been loaded yet, is there a way to do this? Thanks.
推荐答案
embedSWF 的最后一个参数是一个回调函数在嵌入swf时调用。它接收一个事件对象，其中包含一些表示成功/失败等的属性。有关此内容的更多信息，请参阅 swfobject 文档。
The last argument to embedSWF is a callback function that is invoked when the swf has been embedded. It takes in an event object with a couple of properties denoting success/failure, etc. More on this at the swfobject documentation.
swfobject.embedSWF(
"open-flash-chart.swf", "chart", "400", "180", "9.0.0", "expressInstall.swf",
{"data-file":"{% url monitor-graph %}"}, {}, {},
function(e) {
if(e.success) graph();
}
);
