Recent Questions Membuat Trees Down Menu Dengan Javascript
Q: We are interested in using your dropdown menu code for our site but we do have a question.
When the dropdown menu code viewed in IE7 everything is fine but when I view it in opera or firefox browsers the menu bar is off the screen. Have I missed something in the script to position this in the center whin the table it belongs in?
<table border="0" align="center" cellpadding="0" cellspacing="0"
summary="Quaker Meadows Menu">
<tr>
<td>
<script type="text/javascript" src="data.js"></script>
</td>
</tr>
</table> is off the screen. Have I missed something in the script to position this in the center whin the table it belongs in?
<table border="0" align="center" cellpadding="0" cellspacing="0"
A: Try to set exact width for the dropdown menu code in "px". It helps to position themenu correctly in all browsers.
var menuWidth="500px";
Q: I can't see my javascript vertical tree menu in FireFox. What I'm doing wrong?
A: You should set this parameter:
var tmenuHeight = "auto";
Now you have
var tmenuHeight = "0";
Q: I have another question.. after I successfully click and load the data in to my window using the mouseover tab, the tab defaults back to the original default tab.
Because I have to reload my page after the tab has been selected the tab chosen is lost. What do you recommend for "remembering" the tab so that when the page reloads the correct tab is highlighted. I know that I need to set the var bselectedItem but if you have a "nifty" way for me to do that I am all ears.
A: Deluxe Tabs doesn't support API functions which can return theselected tab aslo.
You can set "bselectedItem" and " var bselectedSmItem" parametersbased on your link before you call your data file.
For example, move " var bselectedItem" and " var bselectedSmItem" parametersfrom your data file to your code.
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=<?php echo $seltabs; ?>;
var bselectedSmItem=<?php echo $selsmtabs; ?>;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
You should define seltabs and selsmtabs using server side script.
You can also set it on every page before you call data.js file, forexample:
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=4;
var bselectedSmItem=3;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
Q: Compliments on your product, I particularly enjoy the complete set of gui and java, that allows for the quick changes.
After a couple of months of using the trial, I have now purchased it and installed the license.
My question however regards the performance of the menu. Using firebug I note that my deluxe menu .js are the performance bottlenecks, It appears as if they are not being cached and it appears that collecting them is taking longer then the other .js files. What can I do to optimize the load time of the javascript multi level menu and prevent, reloading it from the server with every page reload. The apache has set the expiry correct I believe, as I understand from the header.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
