Performance.onresourcetimingbufferfull

onresourcetimingbufferfull 属性是一个在resourcetimingbufferfull事件触发时会被调用的 event handler 。这个事件当浏览器的资源时间性能缓冲区已满时会触发。

语法

callback = performance.onresourcetimingbufferfull = buffer_full_cb;

返回值

callback
一个当resourcetimingbufferfull 事件触发时调用的EventHandler

例子

下面的示例在onresourcetimingbufferfull属性上设置一个回调函数。

function buffer_full(event) {
  console.log("WARNING: Resource Timing Buffer is FULL!");
  performance.setResourceTimingBufferSize(200);
}
function init() {
  // Set a callback if the resource buffer becomes filled
  performance.onresourcetimingbufferfull = buffer_full;
}
<body onload="init()">
