Dynamicly Changing Context Menus
Jul 29, 2005
I'm making a web application which is a copy of existing desktop application.
I use telerik controlls for MS visual studio I have a little bit complicated situation beacuse I need context menus but the main problem is that they have to be downloaded from server after the page loads. I can't load all of them on page because there are to many.
This is my solution of the problem. When user right-clicks js download from server through XMLHttpRequest some data from serwer and make menu from them.
But it needs much work to make the menu look nice, now I just have one level
menu.
I've been looking for some controlls that can do the things I need but with
no result.

How can I add more <input type="file" /> -fields by the click of a
button? The idea is that the clients should be able to upload a number
of files from the same form, but I shouldn't need to know how many
fields they need to begin with. Would be good to have an option to
remove fields as well.

I am trying to make a form where the user is only able to select an option from one of the drop down menus and if they click both then submit an error should pop up telling them to select just one. Now I have found this code:
<SCRIPT LANGUAGE="JavaScript"'>
<!--
function validateForm(){[code]....
the first problem is that my menu must be named "id[2]2" which causes a problem due to the bracketed 2 and the 2 after. Is there any way around that?the second problem I forsee is that this will only work with 1 drop down box being unselected. I need a code that will give the warning if nothing is selected OR if something is selected in both drop downs.

Its a very convoluted title, but not sure how to phrase it.I'm using the latest version of jquery. i have a function that creates a new row given an onchange event for the primary select box. This new row contains another drop down box that i want to bind another onchange event. Problem is when the child drop down change event is triggered, if there are multiple children, the alert pops up for the number of children that it has.. horrible explanation heres the code:
Code:
$('#perph_type').change(onSelectChange);
function onSelectChange(){
[code]....

i'm using URL... to load and preview music on my page.It all works really well, when you write pure static html code with just [code]And it will automaticly transform that url into a working custom-player. Done with the soundcloud api.But when i use $.getJSON and dynamicly get down a list of urls that i try to insert with:[code]*side-note(it's the same result with $('#addbtn').click, just wanted to try live as i hoped it would update the elements upon being added. But did not work out.)The url gets inserted into sc-player class div, but the rest never gets transformed into the custom-player with the sc-player.js script.It just remains an ordinary a href. It is as if the sc-player.js never is being "loaded" which i can understand why it won't. Question is how do i get it to successfully transform my urls that are being dynamicly added with javascript into the custom-player instead of just the url to the song?

I am building an sftp application. It has requirements to upload and download. To upload, a target folder that exists on the server needs to be set. I have a jQuery folder tree that dynamically creates a tree view of a directory on the server. Currently in Firefox, Opera, and Chrome if someone clicks on a branch of the tree on the afterClick event I am able to get the target path by using the DOM via node.context.nextElementSibling.value; The code for the afterClick is:

I know how to disable the context menu (the right hand mouse button) and how to replace it by my own menu. I also know that not everybody likes this - so let's not discuss about that here.
What I can't figure out and what I would like to know, is:
1) How to ADD elements to it, i.e. keep the original contents and add something to it;
2) How to RESTORE it to its original contents.
Does anyone know the code for a simple working example of these things?

I am running my website using Weblogic, so the path is something like
http://<myip>:<port>/<servername>/
On JSP pages I can use <%=request.getContextPath()%to get the root
path of the site, ie that specified above. How can I get the same using
Javascript?
For example, something like <a href='/home'>..</awill not work as
that would point to http://<myip>:<port>/home and needs to point to
http://<myip>:<port>/<servername>/home

I am creating html pages with forms where I use Dynarch menu script in a
context menu mode. Their script needs to be initialized like this:
<body onload="DynarchMenu.setup('menu', { context: true });">
This is in the beginning of the html page.
But, in my webpages I have only few pages where I actually use this kind of
menu. Since I use smarty template engine, I have single html-header file for
all pages - it includes the same <html><head><bodyetc. for each page.
So I tried to initialize this dynarch script only within the page that
actually uses this menu. I do it like this:
<form>[...]</form>
<ul id="menu">
[context menu elements definition here]
</ul>
<script>window.onload=DynarchMenu.setup('menu',{ context: true });</script>
This thing works OK in Firefox, however when I load such page in IE6 it
aborts the operation without even showing the page, and the popup message
says:
"Internet Explorer cannot open the Internet site http://example.com.
Operation aborted."
Does anyone know a way how to initialize the DynarchMenu.setup not from the
<bodyelement but from anywhere else in the html page?

I am writing a javascript code that parses dom and finds event
handlers attached to mouseover events. Then i will replace the
existing handler say B() with my own function say A(). When the event
happen and control comes to my function A(), after doing required
processing i will call B() as shown below
<a href = "abc.com" mouseover = "B();"link </a>
while parsing i will have (trimmed down version)
var oldHandler = node.onmouseover;
node.
function A()
{
/ * my code */
oldHandler.call(this);
}
This was working fine as long as B() was a global function. I started
getting problems when B was a member function. For eg:
function Alerter(text)
{
this.text=text;
var me=this;
this.invoke=function ()
{
alert(this.text);
}
}
var sayHi = new Alerter('Hello, world!');
The web developer would have code like
<a href = "abc.com" mouseover = "sayHi.invoke()"link </a>
But this time around, my function A() fails since although i have
handler to sayHi.invoke(), it has to be executed in correct context.
Other wise "this.text" is giving me error because when i say
oldHandler.call(this), i am executing the sayHi.invoke() with the html
element being passed as this.

I am trying to use Jquery as an XML tool to transform xml data other than the DOM.
This works very well and i can change my xml data.
Now i want back my whole xml that i just transform and this is where there is a problem !
$(xml).find('#id').html('some text').parent.parent.parent ... is not a good way
I read something about the defaultContext but it seems risky / hazardous.
Needed fonction would be $(xml).find('#id').html('some text').getRoot().html(); or something like that.

I have a problem with YUI context menu. I want the menu to show different links (with product_id) in every row. I have been struggling with this for days no without result.My code is as follow:
Code:
$result = dbquery("SELECT ..........
echo "<table id='dataset' style='vertical-align: bottom' cellpadding='0' cellspacing='0' width='".$laius."' class='table11'>";
echo "<tr><td >TABLE HEADER</td></tr>";
[code]....
As you can see table row takes menu items according to id (type1, type2 etc).But as my table is created from mysql database dynamically, it does'n work that way.

I am displaying my own context menu in response to a right-click on control (textbox) in my ASP.NET application. In IE, I can suppress the display of the browser's own context menu by simply returning false from the javascript that displays my context menu.How can I suppress the browser context menus from Chrome or Firefox?

Assuming I have an image in my page
I would like to invoke the 'save as' context menu for that image when the user left-clicks the image
I will have a link embedding the image. Clicking the link should invoke the menu and allow the user to save the image
Assuming I have 2 images. Image A and image B.
Image B is a small thumbnail version of image A
Image B is displayed on the screen
When the user left-clicks it, the 'save as' context menu should open (see previous question) and will allow the user to save image A (this is right, the original image and not the thumbnail being display)
Is this possible?

I have a TEXTAREA element. A user right clicks within in to get the context menu and they select "paste". I want my javascript code to know that they selected "paste". I know you can capture the mouse click, but can we capture exactly what event that attempted?

What is the evaluation context of the setTimeout args below? I have a separate Timer instance for each sprite in my program. As coded, "this.Clock" doesn't work.
/*================================================= ===
Timer.js
================================================== ==*/
function Timer(_sprite, _interval) {
var sprite = _sprite;
var interval = _interval;
var isRunning = false;
var timeoutID = false;
this.Clock = function() { // called after setTimout interval
if (isRunning) {
isRunning = sprite.OnClockTick();
if (isRunning)
timeoutID = window.setTimeout("this.Clock()", interval);
else
this.Stop();
}
}
this.Stop = function() {
if (timeoutID) {
window.clearTimeout(timeoutID);
timeoutID = false;
};
isRunning = false;
}
this.SetInterval = function(_interval) {
this.Stop();
interval = _interval;
isRunning = true;
timeoutID = window.setTimeout("this.Clock()",interval);
}
this.Continue = function() {
if (!isRunning) {
isRunning = true;
timeoutID = window.setTimeout("this.Clock()",interval);
}
}
}

I recently started on a tree-folder display and used the Yahoo treeview control. Again it works very well and I am happy with the results. However, after seeing the treeview folder structure, my client asked if it would possible to add a right mouse click context menu to allow users to modify the folder tree -- add new folders, upload files, rename folders, delete folders, etc.
Updating the tree with the new elements is simple enough, but my attempts to implement the context menu have failed miserably. I have studied the Yahoo documentation and I can identify the name of nodes and the label of the element clicked on. But I can't figure out how to add the right-click code to the nodes the YUI Treeview generates.
I have successfully used various right-click Javascript scripts in the past -- but in those cases I was adding the function to an actual HTML element. The YUI elements are generated by the script, and I am at a loss as how to add the code to the generated node elements.
The application is part of a corporate intranet, and will only be used with Internet Explorer 6.0+ on Windows. The new context menu would completely replace the standard Windows context menu.
I am tempted to hack the YUI Treeview script to see if I can add a right click function similar to the Expand, Collapse and Clicked node functions, but I suspect that there is probably a simpler and easier way to do it.
