I want to change the background image of a div class depending on which object (image etc.) is mouseovered.
So, I have in my CSS classbackground-image:<%= eventTypeBG %>; This works fine if I just hard-code theeventTypeBG variable in asp.net code behind file. But is there a way I can know from code behind which image/object is being mouseovered - so I can assign a different background image?
i working on web map of MMORPG gamehttp:[url].....(here is "working" version dont comment a code, its shitty i working on funkcionality,i will perform code cleaning and optimalizacion after i implement all needed functions and solve all my problems)so i have 2 problems:
1) map performance when zooming.i need drawn ~600 dots of NPCs on map and recalculate their positions on map when zoom in/out, my current solution is slow ( cleaning and appending HTML into map content) i wana know if there is faster solution how do it ?
2)i using jQuery tooltips to show data when NPC or fort icon is mouseovered , it works great only with one problem, when i zoom with tooltip opened , it loose "connecion" with fort/NPC icon and tooltip stuck on screen...

View 2 Replies View RelatedI have a very generic webpage that I created to attempt to show a rule that is used. I have used some drag and drop language that I found which enables me to drag and drop elements on the page. This is great. My problem is I have a total of 6 drag and drop items in two catagories. CML and nonCML. If one nonCML is used, I'd like two of the CML objects to disappear. (disappear could even be turning white to make them hidden). I'm very new to Javascript. Is there easy code that would say if an item from Catagory 1 is moved, have 2 items from Catagory 2 disappear?

Subject line would seem to say it all:
How does one trigger the execution of a method within an object or any
other code/function with the setting of an object property?
More elaboration for those who want it:
Suppose we have anObjectType, with a property .description, whose value
can be a string, and the value of .description actually describes the
structure of anObjectType as a string. (The details are not important
about how the structure is described, but if you want something concrete,
think of 'anObjectType' as a DOM Node of type NODE_ELEMENT, and
..description as the property .innerHTML.)
When an instance of anObjectType is created, the value of description is
created with the instance. Indeed, the value of description may not be
set with the construction of anObjectType, but it might be added to the
prototype of anObjectType.
But the property .description is not merely read-only. Fetching the value
of .description returns the string which describes the structure of the
object in a meaningful way.
When .description is set with a value of type string, the string is
checked to see if it properly describes a legally formed structured for
anObjectType, and the instance (and only that instance) of anObjectType is
completely re-built: it might possibly be destructed and then re-
constructed, or all properties (but not methods) which involve descendant
objects are changed to conform to the described structure.
The question is, the setting of a string value of the property
..description of object anObjectType does not automatically trigger a
method/methods (or an exception??) for doing something (such as
restructing the object) as a result of the setting of an object property.
This might be a bit tricky. I want to call a method of a class using the setTimeout code, ok, can do this like this:
var instance = this;
timerID = window.setTimeout( function() { instance.Method(); }, 1000);
Now I want to call a method a number of times from with the class and when they
have all finished I want a second method to be called, I don't want the methods
themselves to be altered, i.e. I want this to be generic.
Here was my idea:
var timerCounter = 0
function CallFunc(func, callbackFunc)
{
timerCounter--;
if(timerCounter == 0)
{
callbackFunc()
}
}
function DoAsyncRequest(func, callbackFunction)
{
timerCounter++;
return window.setTimeout( CallFunc(func, callbackFunction), 1);
}
You would call this using something like:
timerId = DoAsyncRequest(this.method(), this.method2());
How could I do this, tryed using eval to no avail. I just don't know the
language well enough yet.
I'm trying to convert some Procedural code to be more Object Oriented and I'm stuck...
The page is really simple:
It's just a big picture w/ a caption under it, and a few thumbnail pics off to the side, that when clicked, replace the big picture as well as swap out the caption for a new one.
In the code (external JS file):
I've got 2 arrays:
One that holds the thumbnail image file URLs, and the other that holds the captions.
And a function:
I've created an object prototype that I can instantiate in order to:
1.) create the event: do the actual swapping of the thumbnail, and the changing of the caption.
2.) and attach that event to the thumbnail's link onclick event handler.
The code below is the closest I've come to making it work. The problem is that when I click any of the thumbnail links it only executes the last event instead of the one that corresponds to the link that was just clicked. Hopefully someone can take a look at my code and let me know what I'm doing wrong.
Simplified version of the code:
The x,y,z variable assignments are only in the window.onload function for the sake of clarity, but the event object instantiation block has to be in there for anything to work at all.
I know that the event0,event1,event2 objects work, and are attached to the onclick handler because they will swap the last thumbnail and caption when I click any of the thumbnail links. Of course that's the problem now... any click only activates the last event. It's like it attached the last event to all the onclick event handlers.
In fact, if I only create the event0 object, it works like it's supposed to... but when I create the event1 object, it does what it's supposed to and it takes over for event0. Creating event2 makes it take over for all of them. Each subsequent event# object seems to attach its own addy[ ] and caption[ ] to each previous x[ ] link.
I'm using a geolocator service to find the zipcode of a web page visitor using the code below. This will be used to serve up ads to the visitor based on their zip code. The question is, how do I pass the zip code value from the script into an ASP variable, such as a cookie or session object?

As usual, this site works with every single browser known to man ...........except for any version of IE. I have tried using IE's devel tools to no avail ....though I'm a complete newb, so that isn't saying much. Code?Here's the section IE complains about:
function display(str)
{
var nodeList = xmlDoc.getElementsByTagName("item");[code]....
**** UPDATE *****Well ...it looks like I can't have null values in any elements ( in the xml document ). How do you experts satisfy this requirement in an elegant fashion.Since there is no data for certain elements, I'm looking for a reasonable failover solution. Empty quotes?..... still experimenting. A script produces the xml file from a database so some elements do not have data for certain
child elements.
I am trying to make a function run if the mouse is moved over the document but when using the object onmousemove it seems to run the code even if the mouse is still over then document, how can I make it so if the mouse is over the document but isn't moving then don't run the code but once the mouse moves run the code? This is the code I made to handle the mouse move collections.
[Code]..
But with this code it runs even when the user doesn't move their mouse and the notification box pops up every second as the code seems to think a still mouse is a moving mouse.
I was thinking about having a run once system but that would mean if the mouse moves it runs once and then if the mouse moves again the code will not run as it has already ran before.
here is the page I'm working onhere is the jQuery in use
$(document).ready(function() { $('.error,.success').hide(); $("#send").click(function (){ $('.error,.success').hide("slow"); $.ajax({ url: 'add.php?lnk='+$.URLEncode($('[name=lnk]').val())+'&
[code]....
and in this code, it works, the call is made and text is added. in the other code I don't get a change at all. Not even in the database that add.php manipulates.
I am trying to make a gui for clients to edit a php page that displays html and javascript.
I want the user to be able to move html elements around and even edit it like add effects like fade in and out etc.
Then after all the changes I want to overwrite the existing php file that does this for that user. how can you make such changes and then save it to a file?
It's an html / javascript editor but using a gui instead of allowing them to directly touch the code. It would be a security risk if I allow such a thing. So I need to program a interface that would make such changes and save them to file.
Like how can you delete and add new javascript code to the file?
I am trying to hide this code:

Currently my js sheet is called in the header, when I move this link to the footer of my page the code works again, so Im guessing this has something to do with where the jquery code is placed in relation to the code Im trying to hide?
How I can keep my js in the header but still make the content disappear on click?

I am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;
Code:
My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?

I have to make them in one, so that I can pass it around.

I know that document.read is loaded when html page is been loaded. But what's the difference between the two?
I have the following code:
A = {
"value": "a",
};
B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?
I am a novice, almost to an intermediate-level JavaScript guy, so much of this is new to me. I appreciate your patience reading this.
I have a routine that creates some HTML on the fly (updateFilters() function) and after the HTML is created, I attempt to access some fields (elements) on the form itself.
I works fine if I place an alert() statement after the HTML is created, but when I remove, the code errors out.
I have tried the setTimeout() statement, but I cannot grab the element --- undefined or null is returned. It seems that the form is the only element I can get a handle on --- everything else is undefined or null...
Here is the code:
function editQuery() {
var f;
var x;
var myForm = document.forms[0];
// Get the row filters that were used in the last query..
for (f = 1; f < 16; f++) {
var filter = eval("myForm.FilterList_" + f);
if (filter.selectedIndex > 0) {
var methodElement = element("FilterMethod_" + f);
var methodIndex = methodElement.selectedIndex;
var savedFilterMethodValue = methodElement.options[methodIndex].text;
var choicesElement = element("FilterChoices_" + f);
var choicesIndex = choicesElement.selectedIndex;
if (isNaN(choicesIndex)) {
var savedFitlerValues = choicesElement.value;
}
else {
var savedFitlerValues = choicesElement.options[choicesIndex].text;
}
updateFilters(filter); // update the filters
// take the saved methods and values and then update the selections
// Alert here makes the code work..
// alert("Try this");
// Wait for HTML..
setTimeout("completeEdit()", 1000);
function completeEdit() {
// Since the object was updated, get the object again..
var methodElement = element("FilterMethod_" + f);
for (x = 0; x < methodElement.options.length; x++) {
if (methodElement.options[x].text == savedFilterMethodValue) {
methodElement.options[x].selected = true;
break;
}
else {
methodElement.options[x].selected = false;
}
}
// Since the object was updated, get the object again..
var choicesElement = element("FilterChoices_" + f);
for (x = 0; x < choicesElement.options.length; x++) {
if (choicesElement.options[x].text == savedFitlerValues) {
choicesElement.options[x].selected = true;
break;
}
else {
choicesElement.options[x].selected = false;
}
}
// Only display next row if f = 2..
// If only one row was used, no reason display the next row..
if (f == 2) {
displayNextFilter(f - 1); // display it
}
}
clearTimeout(timeOut);
}
}
}
Do I have to pass the object (the form, the elements) to the completeEdit() function in the setTimeout() statement?
I have come across an issue that only happens with IE.I have a custom save function that is designed to handle different ajax submits but I will simplify it for debugging. The issue is that once I make a submit everthing is fine at first. Then once I try to submit a second time it craps out. I am checking to see if there is an onsubmit function and then executing it like so before continuing. After the inital submit it is no longer found. When I alert the typeof document on the form it returns object but when I add the onsubmit it says object expected or object is null or undefined.
Code:
function secureBarSubmit(formId)
{
alert(typeof document.getElementById(formId)); // object always
alert(typeof document.getElementById(formId).onsubmit); // func first time then it is broken
