JQuery :: Adding And Removing DIV-IDs From An Array?
Apr 25, 2009
I have a number of DIVs that I want to make 'selectable' on click, which means that I give the DIV you click on a class (just to show it's selected) and save its ID into an array. When I click on that DIV again, the class should be removed and its ID should be removed from the array as well. My code goes like
var selected_items = new Array();
$(".selectableDivs").click(function() {
if($(this).hasClass("selected")) {
[code]....
But the alert at the end of the code always shows my a list of all divs I ever selected, even those that I unselected again. The IDs are just not removed from the array. Is that maybe because items saved in the array are not exactly $(this).attr("id") anymore?
I want to be able to add row at the end of the table with a 'remove' link which will remove specific row. The code I've managed to write so far:
$(document).ready(function() { $("#add_item").click(function () { var html = "<tr id='item_" + item_id + "' class='item'><td><a
[code]....
The problem is it wont instert the row at the proper place (after the last .item (class) and the remove link wont work for the last row in the table/list.
I'm trying to make a form that will generate some code for game based on what they fill out. The code will be a modification menu of sorts. They will be able to name the menus and submenus and add or remove them if they want. I will need a way to get the information they filled in for each specific menu form, so I figure giving them each a unique id would do the trick. I'm sure there is a MUCH better way to do this, but here's what I have so far:
I'm building an application where the user can add Questions. For each Question they can add x answers or remove them (see screenshot). I can add questions and add/remove answers, For each question that is added I update the 'gameQuestions' variable with 1; The same goes for answers that I add: for each added answer I update the 'counter' variable with 1. When I remove an answer, the app. doesn't know how many answers each question has, it simply decreases the "counter" variable. So when I remove the 2nd question, it doesn't know how many answers that 2nd question has! How can I store the number of answers per question and how do I remove them correctly?
Here's my code so far: $(document).ready(function(){ var gameQuestions = 1; var counter = 1; // Add a New Question... $(".addQuestion").click(function() { var question = "<table id='questionSet"+gameQuestions+"' class='form-table' style='background-color:#cccccc; width=100%;'>"; .....
I have a list of text-snippets which should be inserted into a textarea, separated by a comma. When I click the same text-snipped again, it should be removed from the textarea. I managed to to implement the "inserting" with the following code,
function quickadd() { $('.menu').addClass('red').delay(1000).removeClass('red'); }
So, from what I've gathered from the docs, this doesn't work because the addClass and removeClass functions don't observe the queue. How could I get around this and setup a function that will add a class, wait a second, then remove that class? Would it require me to go outside of jQuery a bit and use some standard JS?
I would like to have two columns, the left column showing all available items with an add button. The right column showing all of the added items, and then adding these together to provide an order total, but with the ability for users to add to the quantity or remove from their order.I have the add item to order bit working on, and the sub-total is working.I started to try to add on add/remove buttons to the right #your-order column but am getting stuck.Every time a user adds another item to their order, more buttons are added, and I can't get the "remove item" button working.The page is located here:URL...Should I paste the jQuery code I am using here?
I have just got myself a copy of SWFUpload to show the progress of file uploads, however, it has a few problems, one of which I am trying to fix with the aid of jQuery. Essentially, if JavaScript doesn't load, then a standard input file element will be shown. But, if JavaScript is enabled, then jQuery removes this, and replaces it with all of the input elements that SWFUpload requires. Is this the best way of doing it, or should I be looking at another option? If so, how would I go about telling jQuery to remove and insert the form field, and each and every attribute the HTML will require?
I have a page that opens up an iframe for the user to be able to select photos. Each photo has a checkbox, and on select I add a hidden form element to the parent frame form. This all seems to work fine, but im now stuck on how to remove the form element when the checkbox is un-checked.
how I can use Jquery to append and remove data into a table by checking and unchecking html checkboxes?(Or any plugin for this?) I would like to generate an online order invoice from the following checkboxes:
< fieldset > <
[Code].....
I find these two example on the net but (The first example looks too similar to what I would like to do but with a table) but Icouldn'tfigure out how to modify them? [URL]
I have a question about removing an item from an array.I am looking to remove an item from the array based on the property.Ie.arr = [{a1: 1, a2: 2},{a1: 3, a2: 4}, {a1: 5, a2: 6}]remove first item from array because a1 = 1.I am not entirely sure how to do this. I tried messing around withgrep a bit, but that didn't turn out well.
I have been doing research on parent object nodes & child nodes. I have a small problem with the code I made. What I need for it to do is depending on which link u click, it adds or deletes the node specified in the function. And the name of the div shouldnt matter as it should be used when clicking on the link <a href="javascript:addevent('divname');">Add Element</a>.
for instance:
"Add element" | "Delete element"
if u click on the add element, then it adds an element, and if u click on the delete element, then it deletes the added element.
Here is the code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>
This code was working originally. Then I had made some modifications and things weren't going right so I went back to how it was originally, and now it's not working!What this does is add a file text box when you click a button & then remove it when you click on its link. I get an error though when I click the Remove link saying that its argument is invalid. I don't understand why since its the exact same line of code the Add button has except assigned to a new variable.
This is the line that's coming up with the error: var d = document.getElementById('addToDiv'); in the removeAdditionalFile function. The error message says 'Invalid Argument'.
Here's the javascript:
function addFileTextbox() { var a = document.getElementById('addToDiv'); var b = document.getElementById('theValue');
I have a lot of information on my site that is in multiple categories. I have a list of categories, each with its own checkbox. By default, all the information is displayed (therefore all the checkbox's are checked by default).When someone unchecks the box I want to hide the divs with that class, and when someone rechecks the box, they should reappear. Here is my code so far. It is hiding the div's fine, but they are not reappearing when user tics the checkbox again.
<script type="text/javascript"> function toggledisplay(category){ if(document.getElementById(category).checked){
I've been learning a lot about jscript and PHP while I've been building my site...now I'm curious about using a little ajax. I have an internal email setup on my site where users can contact one-another...when you click on Inbox, Sent, Drafts, ect it calls a php script and reloads the page. I'm considering for my next release, doing this with jscript but my question is this...
When I print info to the page that I'm on, how hard is it to get rid of the old data that was there? This might be the easiest thing in the world but i don't even know what to call this on google. Also, if that's the norm, how hard is it to add data to a page with out getting rid of whats already there? I've been reading about ajax and I've been using jscripts to check my forms and do simple things but I'm really interested in learning what I really have the power to do here...
I'm trying to get my script below working. I've managed to get it to add fields dynamically but the remove function isn't right... and I can't think of a way round it. how can i incorporate a way for a limit on the number of fields that can be added?
<script type="text/javascript"> function addInput() { var x = document.getElementById("inputs"); x.innerHTML += "<input type="text" />"; } function removeInput() { [Code].....
ah, i've just looked into the operators in more details and -= is just for numbers... so this won't work. i presume this is going to be the wrong method then.
I wrote a simple script to remove an element of an array but I don't think this is the best way to go about it. I have a list of about five elements seperated by ";"
I split the array using array.split(";") command and proceeded to update the elemment by assigning the null value to the arrayindex
array[index]=""
This of course assigns null to the element
But there are two problems
1. The array size is still five instead of 4 and my list is now seperated by "," with an exta "," to go.
I am trying to code a quicklist for my site I am have a little trouble I can add a element in a array but when removing it is not working I have posted the code below
Code: <script type="text/javascript"> var propList; var curPos; var curSize;
Using javascript how do I remove all the data within a particular table row and store it in an array. Then if the user wants it back I append the information to the same table again from the array.
I would like to add a key value to an object array. let's say i have 2arrays: var parArr = new Array('par1', 'par2', 'par3', 'par4'); var valArr = new Array('val1', 'val2', 'val3', 'val4');I would like to obtain ext={par1:val1, par2:val2,pa3:val3,par4:val4}
1. first I have a link for something that works but I want to work better:
[url]
The dynamically resizing textarea boxes are in light orange. They work, but they are rather jerky and you see some "bounce" when adding or removing lines -unlike Face Book which doesn't do this. Can anyone propose a better coding system that is smoother AND less processor intensive?
2. If you really do UNDERSTAND javascript at the programmatic level I'd be interested in having you work regularly for me, but I think I might need to post that in another forum. I'm a PHP programmer, and because I don't understand the JS Kernel and how it thinks, I'm always chasing my tail on it.
