window.onload如果用addEventListener来添加，该怎么添加？

Question

以上代码，load3总是出不来

Answer 1

target.addEventListener(type,listener,useCapture);Firefox浏览器支持addEventListener()，IE是attachEvent()；document.body.addEventListener('onload',function(){console.log('load3');},false);document.body.attachEvent('load',function(){console.log('load3');})
