动态下拉菜单怎么样才能默认打开
下拉菜单的代码是:
scores = new Array(20);
var numTotal=0;
NS4 = (document.layers) ? 1 : 0;
IE4 = (document.all) ? 1 : 0;
ver4 = (NS4 || IE4) ? 1 : 0;
function getIndex(el) {
ind = null;
for (i=0; i <document.layers.length; i++) {
whichEl = document.layers[i];
if (whichEl.id == el) {
ind = i;
break;
}
}
return ind;
}
function arrange() {
nextY = document.layers[firstInd].pageY +document.layers[firstInd].document.height;
for (i=firstInd+1; i <document.layers.length; i++) {
whichEl = document.layers[i];
if (whichEl.visibility != "hide ") {
whichEl.pageY = nextY;
nextY += whichEl.document.height;
}
}
}
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 ";
}
}
}
