Q: Can I use javascript to get the object (getElementByID). If not howdo I hide my dropdown menu on print?
A: You can add a new button to print your page and call onClick event, soyou should write:
<body ....
onClick="document.getElementById('dm0m0').style.visibility='hidden'; window.print();">
...
</body>
Or you can use the same javascript code from your menu item.
For example:
var menuItems = [
["Print", "javascript:document.getElementById('dm0m0').style.visibility='hidden';
window.print();", icon1, icon2],
];
But if you want to hide the menu when your customers push "File/Print"you should write so:
You must create two functions, for example:
function myprint()
{ document.getElementById('dm0m0').style.visibility='hidden';
window.print();
}
function myprint2()
{ document.getElementById('dm0m0').style.visibility='visible';
window.print();
}
You should add this functions into your code.
And then you must write so:
window.onbeforeprint = myprint;
window.onafterprint = myprint2;
Q: Now I need to work out how to add multiple java menu examples to a page? Are you able to reference these separately - is this possible.
A: You can add as many java menu examples as you want on the one page.
You should call
<SCRIPT type=text/javascript> var dmWorkPath = "data.files/";</SCRIPT>
<SCRIPT src="data.files/dmenu.js" type=text/javascript></SCRIPT>
and then call your data files:
<SCRIPT src="data.files/data1.js" type=text/javascript></SCRIPT>
<SCRIPT src="data.files/data2.js" type=text/javascript></SCRIPT>
<SCRIPT src="data.files/data3.js" type=text/javascript></SCRIPT>
<SCRIPT src="data.files/data4.js" type=text/javascript></SCRIPT>
Q: Cross-frame mode: after clicking on a menu item and the subframe is loading and then mouse over the menu when the subframe has not finished loading a javascript error occurs and then the javascript vertical menu breaks.
A: You can get this error when you load pages from the another domain.
JavaScript Tree Menu can support this mode for the same domain only -- ifyou loaded a page to a subframe from another domain, the submenuscan't be shown in it. It happens because all browsers don't allow todo that for security reasons. Just imagine if you'll able to create aframeset from 2 frames, 1st frame will be with a zero height-width,and you'll load your page into it. Then user will go to another domainand your "invisible" frame will change a content of other pages!
Q: I am still struggling with multiple menus on one page.
It is probably something I am doing wrong, but I cannot see it.
A: Now you have:
var absolutePos=1;
var posX="10";
var posY="10";
So, both of your menus have the same absolute position.
You can use relative position and place your menu inside <table>. In this case you should write so:
var absolutePos=0;
