Hi!
Can you help me to understand something?
I have this code that was suplied on the internet and it´s taking time
to me understand.
This is a part of the code:
function navBarInit() {
var menu = new Array();
var layer, norm, high, dmmy;
var last;
var width;
var on, off;
var i, j, x, y, z;
var link;
if (!isMinNS4 && !isMinIE4)
return;
if (isMinNS4) {
origWidth = window.innerWidth;
origHeight = window.innerHeight;
}
window.onresize = navBarReload;
if (navBarMenuWidth < navBarHeaderWidth)
navBarMenuWidth = navBarHeaderWidth;
navBarBuild();
moveLayerTo(navBar, navBarX, navBarY);
showLayer(navBar);
x = 0;
y = 0;
i = 0;
while ((layer = getLayer(“menu” + (i + 1), window)) != null) {
width = navBarMenuWidth;
if (i == navBarMenus.length - 1)
width = navBarWidth - x;
menu[i] = layer;
moveLayerTo(layer, x, y);
z = 0;
j = 0;
while ((layer = getLayer("item" + (i + 1) + "_" + (j + 1), menu[i])) != null) {
norm = layer;
moveLayerTo(norm, 0, z);
clipLayer(norm, navBarBorderWidth, navBarBorderWidth,
width - navBarBorderWidth,
getHeight(norm) - navBarBorderWidth);
if (isMinNS4 && j > 0)
layer.visibility = "inherit";
else
showLayer(norm);
high = getLayer("high" + (i + 1) + "_" + (j + 1), menu[i]);
moveLayerTo(high, 0, z);
clipLayer(high, navBarBorderWidth, navBarBorderWidth,
width - navBarBorderWidth,
getHeight(norm) - navBarBorderWidth);
hideLayer(high);
dmmy = getLayer("dmmy" + (i + 1) + "_" + (j + 1), menu[i]);
moveLayerTo(dmmy, 0, z);
clipLayer(dmmy, 0, 0, width, getHeight(norm));
if (j == 0)
menu[i].high = high;
else {
dmmy.high = high;
dmmy.onmouseover = navBarItemOn;
dmmy.onmouseout = navBarItemOff;
}
link = navBarMenus[i][j * 2 + 1];
if (link != "") {
if (isMinNS4) {
dmmy.document.link = link;
dmmy.document.onmousedown = navBarItemGo;
}
if (isMinIE4) {
dmmy.link = link;
dmmy.onmousedown = navBarItemGo;
}
}
z += getHeight(norm) - navBarBorderWidth;
if (j == 0)
off = z + navBarBorderWidth - 1;
on = z + navBarBorderWidth;
j++;
}
x += navBarHeaderWidth - navBarBorderWidth;
menu[i].offWidth = navBarHeaderWidth;
menu[i].offHeight = off + 1;
menu[i].onWidth = width;
menu[i].onHeight = on;
menu[i].onmouseover = navBarMenuOn;
menu[i].onmouseout = navBarMenuOff;
clipLayer(menu[i], 0, 0, menu[i].offWidth, menu[i].offHeight);
showLayer(menu[i]);
i++;
}
navBarHeight = menu[i - 1].offHeight;
menu[i - 1].onmouseover = null;
menu[i - 1].onmouseout = null;
clipLayer(menu[i - 1], 0, 0, menu[i - 1].onWidth, menu[i - 1].offHeight);
clipLayer(navBar, 0, 0, navBarWidth, menu[0].offHeight);
if (navBarTrackX || navBarTrackY) {
navBarScroll();
if (isMinNS4)
setInterval(‘navBarScroll()’, 20);
if (isMinIE4)
window.onscroll = navBarScroll;
}
}
The trouble is that i don’t see when i is a RegExp or i is a var in the code
just renaming the i var to another name like vari make´s the code not
work!!
I have take the time to see if there’s a object or something that i could
mean other than a RegExp or a simple var but i haven´t across at souch information!!!
If it´s not a RegExp why when i change the name of the var called i it just
stop working???
It just don´t make sense to me!!!
