I am trying to create an interactive to do list in which I enter text into a text box, click a button, and it adds the items underneath. So far I have successfully been able to add items to my list using the button but am not able to remove one item at a time by clicking on it, which is what I would like to be able to do. (Ideally each item would have a check box next to it and when I click that the item would disappear). So far, using the .remove() action I have only been able to make ALL of the items in my list disappear by clicking. I did some research and thought that the .on() action may be what I need. I tried it and now I cannot make items disappear at all. This is my code:
$(document).ready(function() {
$('#button').click(function() {
var toAdd=$('input[name=checkListItem]').val();
$('#item').append.('.list');
});
$(document).on('click','item',function() {
$(this).remove();
});
});
Is there anything that stands out as being incorrect? Or is there a better way to go about this? I am brand new to this and appreciate any and all feedback.Thank you!
I forked your fiddle, with corrected code: http://jsfiddle.net/XEDHJ/2/
Here's where you were having trouble:
$('.list').on('click','input',function() {
$(this).parent().remove();
});
Using on was the right idea, it's perfect for this situation. The way you use on is that you have a parent node, in this case a div with a class of list, and a number of matched child nodes, in this case any element that is an input underneath your parent node. Child nodes are denoted by the selector in the second argument. This will match any input node under your div even if they are created after the page is rendered.
Because I wrapped your input in a <div> tag, we actually want to remove that parent <div>. So we call $(this).parent().remove().
I left my original example below but this should be sufficient to get you going.
It looks like something like this is what you're looking for:

JavaScript
$(document).ready(function() {
$('#button').click(function() {
$('#item').append("<div><input name='checkListItem' type='checkbox'></input>To do!</div>");
});
$('#item').on('click','input',function() {
$(this).parent().remove();
});
});
HTML
<input id="button" type="button" value="Add Item"></input>
<div id="item">
</div>

I currently have made a way so the user can add another text field to the form by pressing on a 'add_another' div, this uses basic JS so when the user presses on the div 'add_another' the div 'author_2' is toggled.
I would like to make it so that when the user presses on the 'add_another' div for a second time it shows 'author_3' div, and when they press 'add_another' again, it then shows 'author_4'. I have put all the CSS and HTML divs in place to support this, I am just trying to adapt my code so it shows one div after another, rather then toggling a single div.
Here is my JS:
<script>
$(document).ready(function() {
$('.add_another').on('click', function(){
$('.author_2').toggle();
});
});
</script>
I have tried altering this code, however with no luck.
I haven't added my HTML as it is just 4 divs, 'author_1' 'author_2' ... 3...4
Thankyou for your help
There are two solutions to Your problem.
First one - use static code
It means the max author count is 4 and if user gets to 4, this is it.
If so - You need to store the number of authors already shown.
var authors_shown = 1;
$(document).ready(function() {
$('.add_another').on('click', function(){
authors_shown++;
if (!$('.author_'+authors_shown).is(":visible")) {
$('.author_'+authors_shown).toggle();
}
});
});
But there is also a second - more dynamic option.
What if user wants to input 10 or 20 authors? You don't want to pre render all that html code and hide it. You should clone the div and change its id or if the (HTML) code (for another author) is not too long, you can render it within JS code.
var div = document.getElementById('div_id'),
clone = div.cloneNode(true); // true means clone all childNodes and all event handlers
clone.id = "some_id";
document.body.appendChild(clone);
If it's a form, then change names of input fields to array as author_firstname[]
Also You can store number of added authors in another hidden field (so you know how long to loop the form fields on the server side.
The second option is a bit more complex and longer, but way more dynamic.
You should make another div when clicked on add_another:
something like this:
<script>
$(document).ready(function() {
$('.add_another').on('click', function(){
$('<div><input type="text" name="name[]" /></div>').appendTo('.your_container');
});
});
</script>
as you see, input's name has [] which means you should treat with the inputs as an array.
let me know if you got any further questions
good luck.
I have a simple problem:
I have a form:
<form>
<textarea type="text" name="comment_text" class="comment-input"></textarea>
<div class="remaining"></div>
<input type="submit" class="button comment-button" />
</form>
Now when the textarea (.comment-text) is focused I want the submit button (.comment-button) to be displayed using jQuery.
$(document).ready(function() {
//display the comment button when the comment textarea is focused
$('.comment-input').focus(function() {
$('.comment-button').fadeIn(800);
});
});
This works fine. The problem is that I have the form in a foreach loop and when I focus one textarea all the buttons get selected. So I was trying to do it with the 'this' keyword something like this:
$(document).ready(function() {
//display the comment button when the comment textarea is focused
$('.comment-input').focus(function() {
$(this).find('.comment-button').fadeIn(800);
});
});
But that did not work. After trying things out for way too long now, I just decided that I do not speak sufficient jQuery to master this simple task and turned to somebody in the know for help!
Thank you in advance!
That is because the button is a sibling element of the textarea
$(this).siblings('.comment-button').fadeIn(800);
find will try to find a child element in the textarea so it will never find your button:
you can use siblings
$(document).ready(function() {
//display the comment button when the comment textarea is focused
$('.comment-input').focus(function() {
$(this).siblings('.comment-button').fadeIn(800);
});
});
Sibling is the solution for this problem , but no more will works if you wrap the submit button in any wrapper(div or span) .
This will work safer -
$(this).closest("form").find('.comment-button').fadeIn(800);
There are others ways to get the correct element other than these 3 answers,
$(this).parent().find('.comment-button').fadeIn(800);
or
$(this).next().next().fadeIn(800);
or
$(this).nextUntil('.comment-button').next().fadeIn(800);
I have a menu that is displayed when a user hovers over an anchor tag with a certain class. The same menu is always displayed, but the anchor tags have a different "accNum" attribute. I want to get the value of the accNum attribute from the "parent" element that displayed the menu and append it to the click event of one of the menu items. Something like;
Actions
Actions
Actions
<div id="ActionsMenu" style="display:none;">
Show Account
</div>
Whichever 'ActionLink' is the one hovered over to display the menu, i want to take that AccNum value and create the onClick event of "ShowAccountValues" something like
onClick="showAccountValues('AccNum value of parent');"
any help would be great. Also, I assume I have to bind this to the document.ready() function for 'ActionLink' which makes sense, but i figured if i could get any of it through this that would be great.
Thank you
Firstly use jQuery to hook up your events, secondly accnum isn't a valid attribute, so use a data-* attribute like this:
Actions
Actions
Actions
<div id="ActionsMenu" style="display:none;">
Show Account
</div>
Then you can update the data attribute of the #showAccountValues link on hover of each a element:
$('.actionLink').on({
click: function(e) {
e.preventDefault();
$('#ActionsMenu').show();
},
mouseover: function() {
$('#showAccountValues').data('accnum', $(this).data('accnum'));
}
});
Then on the click of the a element in #ActionsMenu you can get the accnum:
$('#showAccountValues').click(function(e) {
e.preventDefault();
showAccountValues($(this).data('accnum'));
});
Example fiddle
I'm pretty novice at jquery but I have a table with a field in each row that is dependent on another field (checkbox) in the row. Since its in a table I need to handle them in bulk. I don't think I'm using next() correctly but I'm trying to grab the next .subnet_mask since it will be the one in the same row as hide it. I'll also have to update it once I get that far so that it handles hiding and showing if the checkbox is checked or not.
$(function() {
$('.dhcp').each(function() {
$(this).click(function(){
$('.subnet_mask').next().hide();
});
});
});
Any help is appreciated!
EDIT: ok ok :) well the page is actually written in VisualForce (for salesforce). For simplicty sake lets say its just a form wrapped around a table (up to 20 rows representing different records) displaying a checkbox field with the class .dhcp and a field after it called .subnet_mask that should be shown/hidden based on the checkbox. Is that helpful?
I'd rather do this
$('.dhcp').on('click', function() {
$(this).nextAll('.subnet_mask').toggle();
});
Then you show/hide the next .submask (assuming one .submask per <tr>) each time you click the .dhcp
I'd suggest the following, though this suggestion may well change once I see the relevant HTML:
$('.dhcp').click(
function(){
$(this).closest('tr').find('.subnet_mask').hide();
});
This assumes that there will be only one .subnet_mask element per row (otherwise this will hide all of them) in response to the click event. You mention that this depends upon a checkbox, so perhaps the following would be better, using the change() method:
$('.dhcp').change(
function(){
var that = $(this);
if (that.is(':checked')) {
that.closest('tr').find('.subnet_mask').hide();
}
else {
that.closest('tr').find('.subnet_mask').show();
}
});
References:
change().
:checked selector.
click().
closest().
find().
hide().
is().
show().
You're using next incorrectly. It should be more like this:
$(function() {
$('.dhcp').each(function() {
$(this).click(function(){
$(this).next('.subnet_mask').hide();
});
});
});
For this case, I'm assuming that .dhcp and .subnet_mask are indeed siblings, wit the latter coming immediately after the former. Otherwise, .nextAll() can be substituted for .next()
Edited as per point below.
I am building a site and I have a list of status updates and I want to allow the users to write comments for each of of the items in the list
However I am trying to implement a UI similar to the way stack overflow works
specifically the collapsible comment form / list where a user clicks on add comment on the specific status update in the list, and below that item in the list the comment entry form shows up along with the specific comments already posted.
How do I accomplish this using Jquery?
Note: looking also for the markup example another words a working sample. Thanks
And yes if you could show Async postback that would be nice too
To load the content you can just hook up a click event to populate a div using the load method.
For example in the view you could have something like:-
<%= Html.ActionLink("Comments", "CommentList", "Questions", new { Id = this.ViewData.Model.Id }, new { id = "commentLink" })%>
<div id="commentContainer" style="display:none;">
Loading...
</div>
while the javascript to hook everything up would be:-
$(function() {
$("#commentLink").click(function() {
$("#commentContainer").toggle();
if ($("#commentContainer").is(":visible")) {
$("#commentContainer").load($(this).attr("href"));
} else {
$("#commentContainer").html("Loading..."); //Or just leave it as is...
}
return false; //Prevent default action
});
});
The quick approach (for just showing / hiding the comment area) would resemble something like this:
$(function(){
$('#id_of_element_to_use_for_click').click(function(){
$('#id_of_comment_area').slideToggle();
});
});
The jQuery site will provide you with doco on different approaches such as fades, slides or other combined animations.
Your "Comment Area" I've used in the example here would likely be a <div> tag that contains your existing comments, plus whatever textarea or text input box you wanted users to type their answers into.
Do you need to do an asynchronous postback?
