The above code works fine at Firefox and Google Chrome. And it works at IE 8 for the first drop action. The ajax method is not called after the first call although the append still works.

I'm trying to figure out how to invoke a method on an object given the
object and the method name. For example, here's a simple object with a
method:
function MyObj (pName, pDesc) {
this.name = pName;
this.desc = pDesc;
MyObj.prototype.foo = function() {
return this.name + " - " + this.desc;
}
}
and here is some sample code to manipulate it.
var o1 = new MyObj("nn", "dd");
var s1 = o1.foo();
The assignment to s1 invokes the foo method and gets back the string "nn -
dd" as expected. now I try to find the foo method by it's name:
var funcName = "foo";
var theFunc = o1[funcName];
var s2 = theFunc();
the assignment to s2 invokes the function OK, but not in the context of the
object. can someone tell me how to invoke a function as a method?
Inside client control I generate a button, with script to run.I want to call object's Print() method when this button is clicked, the result value must be passed to Print() as well.How can I do that?This is my object:

CustomControls.FirstObj = function(element) {
CustomControls.FirstObj.initializeBase(this, [element]);[code]....
I have used `jQuery.validator.addMethod` to create a custom validate method that will make sure there is at least one row in my data-entry table. Using Firebug, my breakpoint in the method isn't being hit at all. Am I missing something? Note: I am sure there are problems with the validation method itself, but that is because I can't debug it yet. I am still very much a novice with JavaScript.

I use $().load() to place an HTML snippet from the server into a dialog box which i then need to position relative to the size of the element which has just had the HTML loaded into it. When the main HTML page DOM is ready, I hide() the dialog box, and then use fadeIn() to show with various click() events. I have managed to position the dialog box in the centre of the screen given that there is no content loaded.
However, it seems that when I load the new content into the dialog box the new dimensions aren't taken into account untill the next time load() is called.
Is there a way to get the new dimensions of the element before the dialog is shown in order to position it centre screen?
Here is my code:
function showDialogBox(sender) {
var width = $(document).width();
var height = $(document).height();

Got the following code, which loads some html into a div, then set's the focus to a textbox:
This works fine with 1.4.2, but with 1.4.3 I get an error in jquery-1.4.3.js using Firebug: handler is undefined Line 1797
This happens on line 2 of the code
To me it looks as if the wrong .load method is being called, from the jQuery docs:[url]
Note: The event handling suite also has a method named .load(). Which one is fired depends on the set of arguments passed.
I think the event .load method is being called because line 1797 in jquery-1.4.3.js
if ( handler.handler ) {and comments around it talk about binding events to objects etc.
Can anyone confirm this is the case, or something else is causing the error with 1.4.3

I have an image sitting in a <td> tag, and I want the image to change every 5 seconds. I have a total of 3 images that I need to cycle, and I need it to go back to image1 after displaying image3 for 5 seconds.
I want to call the changeAd() function from the setInterval method within the startAdPAge() function because I am going to be adding more statements to the startAdPage() function, so the body onload event will call the startAdPage() function, which will in turn, call all the other functions.
I was using an if/else statement in the changeAd(), but that only changed between image1 and image2, so i am trying this array, but now it is not changing at all.

I am using the script below to open a new window and once opened,
redirect to that open window from the original window:
private void btnNewPDFWindow_Click(object sender, System.EventArgs e)
{
string NewPage = "NewPageZoom.aspx";
string ScriptBlockNewPage = "<script language='javascript'>var
NewPDFPage=window.open('" + NewPage + "','PDFPage');";
ScriptBlockNewPage = ScriptBlockNewPage +
"NewPDFPage.focus();</script>";
Response.Write(ScriptBlockNewPage);
}
For some reason, with the code above, I have to click the button twice
in order to get it to focus to the 2nd window again.
Any ideas?
I'm just getting started and I went over the initial tutorial. I created an HTML page like this:
<!DOCTYPE html>
<html lang="en">
<head>
[code]....
I have a text field on my page, whose value I am setting through the jQuery cal
$('#Expandable').val("fefefe");
However, when I normally type into the text field, certain events occur as the text field value changes. These events do not occur when I set the value like above. So my question is, after I set the value, how do I invoke any onChange handlers?
Actually it has been just 3 months i started using JQuery and its whole lot exciting with the things we can do using jquery. Is it possible to call a javascript function inside aaspx page created in sharepoint designer on a daily basis automatically .

I have a grouping of private/public functions defined under a namespace like so:
var Effects = function() {
// private variables
var shades = new Array("#ff9", "#ffa", "#ffb", "#ffc", "#ffd", "#ffe", "#fff");
var blindInterval = 20;
var skipFactor = 19;
var highlightInterval = 200;
// private methods
var fade = function( id, idx ) {
//
};
var resize = function( id, queue ) {
//
}
};
var getHiddenHeight = function( id ) {
//
}
};
// public methods
return {
highlight : function( id, interval ) {
//
},
blind : function( el, skip, interval ) {
//
},
toggle : function( id ) {
//
},
zebra : function( id ) {
//
},
};
}();
From mozilla, I'm able to do what's expected by calling the functions like: 'table-1' )" but in IE6 and IE7 I get a "Effects is not defined" error. That's puzzling to me, since they're both defined through a var Effects = function(), and the function itself is self-invoking.
function agregar_row(){
for (i=0; i<10; i++){
row="row/" . i;
if (document.getElementById(row).style.display=='none'){
document.getElementById(row).style.display=''

} }}
This function is intended to make visible a row, just one by each time the function is called. the way im invoking "(row)" is wrong, i think...
I want to make an animated gif that runs through one loop
and then stops. But I want to invoke it at random time
intervals...so, for instance, a tight head shot
of a person's face winks at the viewer once or twice per minute,
at unpredictable intervals.
I think I could figure out how to use rand() and setTimeout(...)
to create the random time intervals, but I'm not sure about
how to start the one-loop animated gif. Would I have to reload
the whole page? Or is there someway to restart the gif animation
*without* reloading the whole page?....probably not, the more I
think about it.
I'm trying to call/ mimic an onchange function/ event after a user has
clicked a checkbox. In response to which a buncch of other ones need to be
checked as well.
The caveat is that each of those child-checkboxes need to have an onchange
action take place. All of these child-boxes *have* got a working onchange
eventListener attached (thx to an old post of Lasse Reichstein Nielsen).
Following a snip that suggests (or so the debugger suggests) that the
inputElement.onchange is void, so calling onchange becomes a bit hard.
Any suggestions?
.....
inputElement = _row2checkbox[tb.rows[i]["id"]];
inputElement["checked"] = el["checked"];
if (inputElement.onchange) {
inputElement.onchange();
}

I have a number of image files that have been pre-selected by the user
for downloading. I'd like to be able to have the user click a button
and have a directory browser pop-up window available for the user to
select the directory into which the image files will be downloaded.
I thought that this would be simple to find but...
If this is possible I further need to know:
1) how to access the directory path string (which will be used to
download the files)
2) how to set any available default values for the directory bvrowser.
:)Per JMRKER's suggestion I researched Query Strings and partially solved my original request on how to pass a parameter. Now I need to learn how after passing that parameter, how to invoke some code.In an html file I call the program listed below entitled "ShirleyLee.html". The call is initiated by the following statement: onclick="window.open('ShirleyLee.html?Player=WindowsMediaPlayer'"In the body of ShirleyLee.html I call a function in the <head> entitled "DeterminePlayer". This function will parce the url used to open ShirleyLee.html.I tested this code and it works. In the Javascript code located in the <body>, the If clause: "if (SplitQueryStringStoreInArray[1] == "WindowsMediaPlayer")" will trigger the Alert box which will then display "WindowsMediaPlayer" which was parced from the url in the DeterminePlayer function located in the <head>If you look further down, just below the function call in the <body> you will see 11 lines of code which is a table that is comprised of the code neccessary to utilize the Windows Media Player plus parameters.
My question is, how do I invoke this code in the true area of the conditional clause located in the <body> that now temporarily contains: "alert("Player = " + SplitQueryStringStoreInArray[1]);"The following is the file: "ShirleyLee.html"
<html>
<head>

currently we are having a scenario wherein in a JSP page we invoke the Microsoft Outlook client (open the Outlook client) using ActiveX api.. This we are doing using a java Script function which is called when the JSP page gets loaded. The body of the email is pre populated in a HTML format when the Outlook client opens up.Now we have a requirement wherein we need to open up the Lotus Notes client in a similar way ..Could someone please advise/help how this could be achieved ..whether there are some standard api's which could be used here.
2. Also in case there are 10 users who are using microsoft outlook as their email client while the other 10 users are using lotus notes for emailing..then in this case how could this be handled..
I think the last thing people seem to learn about in JavaScript when they're not coming from other programming languages is variable scope. Some even get all the way into AJAX without having learned about scope, and this is a time when it's really needed. Although the scope of JavaScript variables is non-complex by nature, it's something we should all get a full understanding for before we move too far.
Section 1: What is "scope"?
Section 2: The "var" keyword
Section 3: The "this" keyword
Section 4: Closures or "Anonymous functions and self-invoking closures

View 1 Replies View RelatedI'd like to know if it's possible to invoke associated onChange action of check box when changing it's state with another javascript command... ie.
<input type="checkbox" name="y" onChange="javascript: func('var');">

When I execute last line I'd like func('var') to be run as well. Unfortunately it doesn't happen as of in the example above.
I'm trying to do something, but I don't know if it's possible.
Basically, I want to have a public static class method that could
access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing
something like
function method(param) {
param.privateMethodOfClass();
}
I've done a lot research and experimentations but just can't come up
with a solution... I don't even know if what I'm trying to do is
possible.
