Javascript/CSS Based Menu
Jan 16, 2005
I like it because everything is modular, the submenus stays within the shape of the rectangle without jutting out horizontally across the website. However, when I tried to tweak with the code some of the images just wouldn't show up. I saved the ENTIRE website but modifying the names of the images just didn't work. As a result I am comtemplating on doing this same menu in Flash. (loading the same positioned swf on top of another, on top of another).

I have three dropdown menus (side dish, veggie, fruit). Based on the side dish selected (fruit or veggie), I'd like the fruit or veggie menu to appear automatically, while the one not selected stays hidden. Below is the code for the HTML part. I have no idea how to get started with the javascript.
<head>
<title>Untitled Document</title>
</head>
<body>
<form id="form1" name="form1" method="post" action="">
<label>sidedish
<select name="sidedish" id="sidedish">
<option value="fruit">fruit</option>
<option value="veggie">veggie</option>
</select>
</label>
<label>veggie
<select name="veggie" id="veggie">
<option value="carrots">carrots</option>
<option value="corn">corn</option>
</select>
</label>
<label>fruit
<select name="fruit" id="fruit">
<option value="banana">banana</option>
<option value="orange">orange</option>
</select>
</label>
</form>
</body>
</html>

I'm trying to customize the popup menu based on which table I right-click on. I have disabled the right-click function on the page except for the tables. I did this on purpose. This web page will be called from a python software, using the IE activeX, so no worries here about the browser compatibility.I just don't know how to get the variable from showmenuie5(getid) and transfer it to the menu.[code]

I am new to javascript stuff but am looking to develop a form which includes 2 drop down menus but I would like to grey out some options in the second one based on the selection in the first. Basically this is a simplification of what I have:
<select name="orientation" id="orientation">
<option value="OR1">South</option>
<option value="OR2">East</option>
<option value="OR3">North</option>
<option value="OR4">West</option>
</select>
<select name="location" id="location">
<option value="L1">Front Left</option>
<option value="L2">Front Right</option>
<option value="L3">Rear Left</option>
<option value="L4">Rear Right</option>
</select>
What I would like is that if south or east are selected for orientation then I can only select front left or front right but if north or west are selected then only rear left or rear right are available.

there was any premade dropdown menu which opens based on what position you are on the page.
For example, when I'm on the top of the page and hover the mouse over the dropdown menu, the menu opens upward instead of downward because the navigation is mid-screen. But if I was to be more than halfway across the screen and still see the navigation as it was on top of the screen and hover the mouse over it, the dropdown menu opens downward as oppose to up.

I am looking to build as basic as possible, a form that has 3 select dropdowns that have predetermined options. The user will select the first option and based on that option the second will populate and based on that, the third one will give the last option. Now, when the last one is selected, i need a div or a paragraph displaying information to be displayed.So here's the framework.
Option 1 = fruit or vegitables of which fruit is selected is selected by the user
Option 2 = Apples, Grapes, and pears of which apples is then selected
Option 3 = Red, Green and Yellow of which Green is selected.
Once green is selected, I need a description about the green aple to be displayed.

I have a Javascript function that allows the display of a textbox upon selecting an option from a dropdown menu. In my case when a user selects listbox as the option, the text box appears. I want the same thing to happen when another option (checkbox) is selected. when I repeat the JAVAscript code, the first textbox(listbox's textbox) appears irrespective of which option(listbox, checkbox) I select. I want to be able to appear/disappear only the respective textbox. Here is my code.
<html>
<script type="text/javascript" >
function showfield(name){
if(name=='lstbox')document.getElementById('div1').style.display="block";
else document.getElementById('div1').style.display="none";
}
function hidefield() {

I have a simple form - I want to disable the text field if Choice 2 from the dropdown menu is selected. I have this working with the code below, but for some reason if I go back and select choice 1 after selecting choice 2 the text field remains disabled. I only want it to be disabled if choice 2 is selected.

I have a background image that auto-resizes based on browser window / screen resolution. I want my top header menu, which requires links, to act in the same way and be in roughly the same position/size based on browser window. Is this possible? In the sample below, the image is just part of the background image to give you an idea of the look I am trying to duplicate.Is there a Javascript out there that will help me or will I be stuck having to rework my design?

I'm pretty bad with Javascript, but I need to hide or show a snippet of text (could be inside a div without problems) based on the selection of a dropdown menu (<select>). If they choose anything with the word "Series" on it, I need to show the snippet. If they choose anything without "Series" on it, then the snippet needs to disappear. I should mention the snippet is part of a form, just a checkbox but that shouldn't be a problem I don't think.

I have a web-application project which requires interactive User
Interfaces. It is more like a web based xml content editor. I have seen
a few javascript based text editors but not much flash based ones. I
dont have much experience on neither of the technologies so I have to
spent some time to develop my skills on them (your suggestions are
wellcome:) my questions are:
1. Is JavaScript and the today's internet users's enveronment
(browser-speed-security) mature enough to run a heavy javascript based
web application ?
2. I have the "sceptic feeling" that with Javascript, programmers have
very little control on runtime environment or javascript behaviours,
errors are not so predictable on client site. (Still I see lots of
websites with javascript and a yellow Error sign on my browsers left
bottom corner). Is it still quite complicated task to make the
javascript run properly on most of the users site (say 90%) without
complicated browser/version/DOM tricks and customisation?
3. Is Flash a better option for a interactive UI application? If so why
is it still just an "animation" technology?
4. Is it possible (and easy) to mix the Flash with other technologies
like Ajax or ASP.NET ? Is it possible (and available) to make
flash-based components (like special behaviour combo box, or new kind
of UI components) which can be used in an asp.net web application?

Not sure how useful this is, exactly. It requires a bit of explanation.
function assert(assertString, thisObj) {
var throwException = arguments.length > 2 ? arguments[2] : false;
var argsObj = arguments.length > 3 ? arguments[3] : {};
var argsString = "";
for (var property in argsObj) {
argsString += ("var " + property + " = " + argsObj[property].toSource() +";
");
}
var func = new Function(argsString + "return (" + assertString + ");");
var mustBeTrue = false;
try {
mustBeTrue = func.apply(thisObj);
}
catch(e) {
// fall through. An exception will leave mustBeTrue as false, and the assertion still fails.
}
try {
if (!mustBeTrue) {
throw new Error("ECMAScript assertion failed: (" + assertString + ")");
}
}
catch(e) {
if (throwException) {
/* For Mozilla, use
throw new Error(e.message + " stack:
" + e.stack);
*/
throw e;
} else {
/* For Mozilla, use
dump ("Warning: " + e.message + " stack:
" + e.stack);
for (property in argsObj) {
dump(property + " = " + argsObj[property] + "
");
}
dump("
");
*/
alert(e);
}
}
return mustBeTrue;
}
So what is an assert()? In C++, it's usually a macro the programmer uses to test a statement that must be true for the code to function properly. The statement, I believe, is called an assertion.
If the assertion evaluates to false, then there's a bug in the program. It's basically a way for the programmer to detect for bugs in the program that the program wouldn't be expected to know about.
This assert() function takes a string as its first argument, which must evaluate to true. If said string is true, everything's hunky-dory, and the function returns true. If said string is false, then the function notifies either the user or the application (depending on the third argument, which is optional), and returns false. If there is an exception generated while testing the assertion, the assert() function returns false.
The second argument is the this object of the code calling the assert(). So you could basically call the assert() like this:
assert("1 == 1", this);
The optional third argument, which defaults to false, determines if a JavaScript error should be thrown. A false value means notify the user, but don't stop execution (dump() is a Mozilla-specific function, used in debug builds). A true value means throw the exception.
The fourth argument should be an object literal for passing variables into the assertion for evaluation. For instance:
if (assert("x == 1", this, false, {
x: 1
} )) {
html_input.value = "x is indeed equal to one!";
}
All this works because the assert() function creates a local function object based on the information you feed it, and then executes that function.
This code is available under the Mozilla Public License (MPL1.1) tri-license scheme. Feedback?

I am trying to do a site in FrontPage2003 using dwt and css. I added a
drop-down javascript menu (EZMenu). It is working however the CSS overrides
the formatting of the menu.
Is there a way to either shut off the CSS for the menu or add lines to
either the JS file or the CSS page to let the menu formatting show thru?

I have a logo jpg and then a jpg which is a solid blue line. I am
trying to make my javascript menu load underneath these two. I have put
the src="menu.js" after the two jpg's in the code but it always loads
above them in the browser.
Is there a way of getting my menu as the third item down from the top
or will javascript always load to the top?
