你 2次指定onload,所以达不到想要的结果修改如下：

function initIt(){ if (!ver4) return; if (NS4) { for (i=0; i<document.layers.length; i++) { whichEl = document.layers[i]; if (whichEl.id.indexOf("Child") != -1) whichEl.visibility = "hide"; } arrange(); } else { divColl = document.all.tags("DIV"); for (i=0; i<divColl.length; i++) { whichEl = divColl(i); if (whichEl.className == "child") whichEl.style.display = "none"; } }}
