网站flash右键定制
问：有的网站flash右键定制是怎么做的？
终极讨厌：看一个小示例。
var expandmenu = new ContextMenu();
function f1_func() {
tab1.enabled = false;
}
function f2_func() {
tab1.enabled = true;
}
expandmenu.hideBuiltInItems();
var tab1 = new ContextMenuItem("把我变成灰色", f1_func);
var tab2 = new ContextMenuItem("把它变回来", f2_func);
expandmenu.customItems.push(tab1, tab2);
_root.menu = expandmenu;
function f1_func() {
tab1.enabled = false;
}
function f2_func() {
tab1.enabled = true;
}
expandmenu.hideBuiltInItems();
var tab1 = new ContextMenuItem("把我变成灰色", f1_func);
var tab2 = new ContextMenuItem("把它变回来", f2_func);
expandmenu.customItems.push(tab1, tab2);
_root.menu = expandmenu;
