window.onload=function(){console.log('load2')}document.body.onload=function(){console.log('load1')}document.body.addEventListener('load',function(){console.log('load3')})以上代碼，load3總是出不來(lái)

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