I use the following two javascript functions to set or retrieve the
current menu item by using the item value:
function idbGetSelected(menu_object) { /* return value of
selected menu entry */
for (i=0;i<menu_object.length; ++i) {
if(menu_object.options[i].selected == true) {
return menu_object.options[i].value;
}
}
return "";
}
function idbSetSelected(menu_object,value) { /* set selected menu
entry to entry with supplied value */
if (menu_object) {
for (i=0;i<menu_object.length; ++i) {
if(menu_object.options[i].value == value) {
menu_object.options[i].selected = true;
} else {
menu_object.options[i].selected = false;
}
}
}
return "";
}
Setting a menu entry would look for example like this:
idbSetSelected(document.getElementById("color_menu"),"color_custom");
