IndexOf() Not Registering With Certain Code Blocks?
Oct 30, 2009
my indexof() function is not being recognized when I enter an email address for an unsubscribe form I have on one of my pages. Additionally, the confirmation message is also not showing up when the email address IS valid. Here is my code that I am using on a PHP page:function Unsubscribe() {
var IsValid = document.getElementById("email").value;
alert(IsValid.indexOf("@"));
exit;
[code]....
to those PHP experts, I am aware of the RegEx function for validation, but I don't understand it, which is why I don't use it (in case anyone points that out).The other thing that is problematic is that the PHP code is automatically using HEADER() regardless of "email"'s value

I have been creating a little Javascript game. People buy items and then sell them for a profit. WHen someone buys something, it displays an image of the thing they just purchased (and have previously purchased). I want them to be able to "sell" the item by clicking on the picture. I have the money system set up, but I'm not sure about how to get rid of the picture when the user clicks on it. Is there anyway to get rid of a certain string (<img src="BLAH" class="BLAH">) when clicked on? I'm pretty sure you can use indexOf() somehow to do this, but I'm not exactly sure how

If you see my last post, it was a piece of this code that I was learning for/loops but now I have that all working(hence the new topic) and I'm having a problem with indexOf. Here's the whole script(its a fun little date picker)
function popSel(v){
var days;
var x;
if(v==01 || v==03 || v==05 || v==07 || v==08 || v==10 || v==12){
x = 31;
}else if(v==04 || v==06 || v==09 || v==12){
x = 30;
}else if(v==02){
/*var yr=document.getElementById("year").value / 4;*/
var yr = 2003 / 4;
if(yr.indexOf(".") == -1){ /*If you divide a year by 4 and the value is a whole number, it's a leap year*/
x=28;
}else{
x=29;
}}for(i = 1; i <= x; i++){
days += "<option value=" + i + ">" + i + "</option>";
}document.getElementById("day").innerHTML=days;
}
The whole script works but feb doesn't change?

I'm trying to figure out how to make this code not be case sensitive when it comes to the "default.asp" line. The code below in the head of a XHTML template and adds the CSS info only on the homepage, which is domain.com or domain.com/default.asp. It works just fine, but when I visit [URL].. it doesn't work. How do I make it case insensitive?

This may be a repeat post, but I can't seem to find the answer in these forums. Here is the question: I have a div with id "someDiv". I am obtaining an HTML string via XHR and intend to insert it in the DIV. I use .html(theHtmlString) and it renders just fine. But the newly inserted elements are not in the DOM - either by name or id. How do I register them in jQuery?

I'm having a hard time figuring out how to refer to an object while inside a jquery event function. In the following example, "this" at first is referenced as #myDiv. But inside the draggable event, "this" refers to something else. I am not sure what it is referring to, but how do I reference the original object (Human) from within this event?
var Person = new Human("#myDiv", "my data");
function Human(element, myName) {
this.name = myName;

In part of this project, I am create a dynamic table row that contains a dynamic textbox in one of its cells. When the textbox is created, I try to attach an onkeypress event and it only works in IE. I feel like I'm missing some fundamental piece here, and am pulling my hair out because of it :mad:. I feel like i've tried everything possible to even get firefox to read this code.
//----- WHERE THE TEXTBOX is CREATED -----//
var cellProd = row.insertCell(2);
var txtProdQuant = document.createElement('input');

I have an issue with a registration form. What I would like to do is only allow a certain email domain in the 'email' field. Eg. Only allowing @gmail.com email addresses, and all others would receive an error. This is the line of code that I believe needs changing:
function isEmail(valor){if(/^w+([.-]?w+)*@w+([.-]?w+)*(.w{2,4})+$/.test(valor)){return(true)}else{return false;}}
I am not too familiar with this but through my hours of research, I believe that I need to add something to this line.

I've got a bunch of <div> blocks, with a fixed width and height, that are all left floated.I would like a user to be able to click a "remove" link and have it delete a box, and all the boxes to the right "slide in" to fill the void created.I have it working well enough with a "snap" transition. I made that term up because I'm not sure how else to describe it--by "snap" transition I mean that the boxes to the right "snap" into position--there's no "sliding" or easing as they move, it's just moment their in their old positions, and the next moment, everything has been rearranged and they're in their new positions. how to adequately describe it in text, so here's a video showing what I mean: [URL]

I was just wondering if it's recommended to have all your javascript contained in a single unified block or if it's okay to have them spread out across the document? I find the second approach ensuring JS is located near code that is directly associated increases readability, but I'm worried it may have a negative effect on performance, however minor.

I'd like to process several blocks of parallel actions, but in a sequential manner.
As an example:
Thus, I want to process blocks, from which I don't know how long they will take and afterwards have a couple of actions, before beginning with another block. I already tried it through using .queue, .ready() etc, but that leads to very ugly or unusable code..

I'm trying to understand how jQuery works, so I wanted to create something in order to learn a little bit ;-) here's the case:
I want to create a box with a text in german. Above the text, there are buttons in order to change the language. So, by clicking on "French", the german text disappears and is replaced by the french one. So, I created the buttons and the DIV-Blocks.
The question is, which function I should use with jQuery in order to achieve my goal (?) show / hide ? replace? First, I should show only one DIV, and hide all these others, no?

How to determine how a absoluted positioned element was positioned?
For example, a div positioned with bottom: 10px, will have a "top" read in Firefox. But if using "top" to move the box, instead of moving it, it will grow or shrink.
