JQuery :: Use Of This Keyword With And Without String

Aug 29, 2011

I was reading thegetting started with jquery. And got confused with use of this in these 2 code segments.
$(document).ready(function() {
$("#orderedlist").find("li").each(function(i) {
$(this).append( " BAM! " + i );

$(document).ready(function() {
// use this to reset several forms at once
$("#reset").click(function() {
$("form").each(function() {
When do we need $(this) and this? And what is the difference between them?

JQuery :: .click() Event Handler And The 'this' Keyword?

Nov 13, 2011

My plan is to create a JavaScript class, with some functions and variables, and one of the functions is called when a user clicks on a certain element. However, I need to find out the ID of the element that was clicked (in the example, that of the <p>) for further processing. It looks basically like the following:


The result was very crazy, because console.log(this) gave me the node as result, and console.log($(this)) did the same only as jQuery node, but trying to find out the attribute via jQuery gave undefined as result. I haven't checked if this.id would work (should probably), but I'd prefer to keep the whole script in jQuery, if possible. I suspect it may be an overusage of the 'this' keyword, but if so, what's the proper way to do it?

Date-Dependant Image Map Using JS: Possible?

Sep 12, 2007

Basically, I'm trying to have a navigation bar on my website with the days of the week on it. I have 7 images of the bar, each starting with a diff day (so one is monday-sunday, the next is tuesday-monday, etc) and I've so far managed to make it display the correct image depending on the day with this code:

var a= new Date();
var b= a.getDay();
switch(b) {
case 0:
document.write("<img src="sunday.jpg">")
case 1:
document.write("<img src="monday.jpg">")

My problem is that I need the days to be links, so I tried creating an image map:

case 1:
document.write("<map name="Monday">" +
"<area href="tuesday.htm" shape="rect" coords="106, 30, 196, 88">" +
"</map>" +
"<img border="0" src="images/mon.jpg" usemap="Monday" width="770" height="90">")

Which really didn't work either. Which brings me to my question: Is it possible at all to do what I'm trying? And have I made a total mess of the code?

PHP/MySQL Dependant Drop-down Menu?

May 13, 2009

I'm looking at integrating a JavaScript/PHP/MySQL dependant drop-down menu order configurator. My client sells a lot of high-tech stuff, which needs to be customized, so I was thinking that this would be the perfect solution.

Rather than have the list statically populated with HTML tables, if the clients could automatically configure them to their specifications, then this would be the best option to avoid confusion, as well as save my client's support desk time and money during the pre-sales process.

However, I am not having luck finding what I need when Googling for dynamic dependant javascript php menus... a lot of basic JavaScript menus comes up, and that's great, and I really don't have the time to spend on this project creating a custom mysql/php implementation.

Resize A Page Dependant On The Content Of An Iframe?

Jan 19, 2010

Ive written some code to try and resize a page dependant on the content oof an iframe. Code is as follows:

function sizeAdj() {
var elFrame = document.getElementById('theFrame');
var elTable = document.getElementById('tableGrab');
var elDivMain = document.getElementById('main');
var elDivWrapper = document.getElementById('wrapper');

I originally thought that I would just be able to resize the iframe and the other elements would follow suit but as you can see Ive tried to resize the other encasing elements also. The code resizes partially in chrome but only to a certain point and not to the full height of the doc content.

Settimeout And This Keyword

Apr 3, 2007

I am modifying the suckerfish dropdown code to use settimeout to have
a slight pause before the menus disappear to make it more user
friendly. I have hit a snag with the following statement:

[0].style.display = "none"', timecount);

If I put take the statement

this.getElementsByTagName("UL")[0].style.display = "none";

out of the settimeout function, it works. (w/o the pause, obviously).
With the settimeout function, I get "this.getElementByTagName is not a
function" error.

I have tried putting this.getElementsByTagName("UL")[0] is a variable
and then using that in the settimeout function, but then each li will
only open the very last menu in the list. (ie all the menu items open
the last sub menu) Code:

Grab The 'this' Keyword Position

Sep 8, 2006

Is there a way to find which element in an object array the keyword 'this'
is acting upon?

For example:

function doMe(){
var aTags = document.getElementById("list").getElementsByTagName("a");
for (var i=0; i<aTags.length; i++) {
aTags[i].onclick=function() {
this.className = "myClass";

Inside of this function is there a way to determine where in the array this
'this' is and return the integer?

var theID = this.somethingOrOtherThatWouldGiveMeTheNumber;
var elementID = document.getElementById("myDiv"+theID);

I could just give each image an ID and not use the 'this' keyword, but I haven't used it much so I'm curious about it. It's sending the image element to the function, so why can't I modify the src attribute with that information?

Keyword In Callback Within Object.

Apr 27, 2007

I'm creating a list with buttons that show and hide some of the list elements to create the effect of scrolling. I've built an scrollList object so I can apply this to any list. When you create the object and pass it the id of the <ul> and how many items of the list you want to be displayed. It will add the scroll down and scroll up links and add an Event.observe to them (I'm using the Prototype library).

This code creates the object

var main_news_articles;
main_news_articles = new scrollList('main_news_articles', 5);

The problem I am having is with the callback functions of the onclick event of the links (scrollUp and scrollDown). The this keyword within these functions is refering to the link and not the object.

To try and solve this I've made the title attribute of the link the same as the variable name of the scrollList object. I can reference the scrollList object like so Code:

Retrieving Keyword In Alert Box To Welcome Visitor

Aug 13, 2010

I am looking to insert a keyword in to a javascript alert box when someone visits my website, so say they came from codingforums, it would say "Welcome, CodingForums.com Visitor". My keyword will be passed from the ad platform I am working with and shows up correctly in the tracking, so I'd imagine it's just a case of having the snippet of code for it to show in the alert, correct? If there is no keyword, I would just like it to say "Welcome Visitor" or something.

Using New Keyword With Variable Length Arguments?

Dec 22, 2009

I want to use the new keyword to instantiate an object. The catch is I want to pass in variable length arguments.
function Foo () {
this.args = Array.prototype.join.call (arguments);
}var args = ["arg0", "arg1", "arg2"];

The following don't work (though I understand why):
new Foo.apply (null, args);
new (Foo.apply (null, args));
(new Foo).apply (null, args);
How to do what I want without modifying Foo's source code?
