I want to use jQuery to select everything on a page except a certain div. My question is similar to this answer, but that solution selects only divs, I want to select everything.
In this example Fiddle, I want to select everything that does not have, or not the descendent of an element with, a class of "kids". So clicking on the "grandkids" and "kids" should not show a log entry, but clicking on the "parent" or the image would.
The page will have a very complex structure so something like this wouldn't be feasible.
You can try the not selector
$('body *').not('.kids, .kids *');
or if you are trying to register an event handler then
$(document).on('click', ':not(.kids, .kids *)', function(){
})
use this code, this code exclude .kids element and inner elements of .kids class
$('body').click(function(e) {
if(!$(e.target).closest('.kids').length){
console.log(e.target);
}
});
DEMO
Use e.currentTarget in jquery
$("#parent").not($('.kids')).click(function(e) {
console.log(e.currentTarget);
});

I want danamically create select element in horizontal block. And have funny result. What is the correct way?
JSFiddle
You need to define where you want to append the new elements. For this, use .after(). And then you need to apply styles on the generated/modified controlgroup.
Demo here: http://jsfiddle.net/Palestinian/rKGtQ/
Code:
// append select menu after Button div
$("#Button_show_filters").after('<select id="sm"><option>Opt 1</option><option>Opt 2</option></select>');
// apply styles on select menu
$("#sm").selectmenu();
// add options to controlgroup
$( "#test" ).controlgroup( "option", "corners", true );
// create controlgroup
$( "#test" ).controlgroup().trigger('create');
controlgroup div ID is #test.
I think the main problem is that every time the "Push me!!" button is pressed, you are appending a select element with an id attribute of sm. Having multiple elements with the same id is invalid HTML and can cause problems with Javascript. See this question.
Namely, the $("#sm") line doesn't know which select you are trying to target.
Maybe you should try something like this:
$("button").click(function () {
$("#div_for_harakteristikinomenklatury_list").append('<select><option>Opt 1</option><option>Opt 2</option></select>');
$("#div_for_harakteristikinomenklatury_list select:last").selectmenu();
});
Also, you should get rid of the onclick attribute for the button. You don't need it. Passing the click handler to the click function should make the function run when the button is clicked.
Instead of using id you should use class and apply selctmenu only on last appended select element. Check this fiddle
$("button").click(function show_filters() {
//alert("Hello");
$("#div_for_harakteristikinomenklatury_list").append('<select class="sm"><option>Opt 1</option><option>Opt 2</option></select>');
$(".sm:last").selectmenu();
})
Updated Fiddle
change the $("#sm").selectmenu(); to $("select").selectmenu();
With above mentioned method no matter what is the id or class of the element you newly pushed, it'll get the styles applied.

I'm building a recipe saving application where I have a form that looks like this http://jsfiddle.net/LHPbh/.
As you can see, I have a set of form elements contained in an <li>. You can click Add Ingredient and have more li's added to the field.
My problem is:
The first li is the only one that deletes. If you click Add Ingredient, and then try and delete that one, nothing works?
Is there a way to not have the first li have a delete by it, but all subsequent li's have a delete link on the side? (Just because there should always be at least one ingredient?)
When you call clone(), it isn't duplicating the events. You need to call clone(true) in order for it to do this, as explained in the documentation.
You did not put an event listener on the cloned elements. Also, you should not give the "delete"-link its own id, as those need to be unique.
To make the first ingredient have no delete button, just don't include one in your markup but only dynamically create and append them to the cloned elements:
var deleteButton = $("<a class='float-left'>Delete</a>").click(deleteThis);
$('ul#listadd > li:first')
.clone()
.attr('name', 'ingredient' + newNum)
.append(deleteButton)
.appendTo('ul#listadd');
function deleteThis() {
var li = $(this).closest('li')
li.fadeOut('slow', function() { li.remove(); });
}
Demo at jsfiddle.net
http://jsfiddle.net/LHPbh/2/
$('.deleteThis').live("click", function () {
var li = $(this).closest('li')
li.fadeOut('slow', function() { li.remove(); });
});
It is answer to the 1. point. The problem was, that the eventhandler binding did not happen in newly created elements, because this code runs only on the load of the page. This can be solved by using .live(). And an other problem was, that id-s must be unique. So instead id, here you can use class .deleteThis.
http://jsfiddle.net/LHPbh/19/
This has added answer to the 2. point:
if ($("#listadd li").length == 1) {
return;
}
If the list only contains 1 li element the rest of the callback will not run.
You are adding items that are added to the DOM dynamically, thus jQuery can't access them :)
In this case you can use the following code:
$(document).on('click', '.selector', function(e) {
//code here
});
Secondly, you were loading a quite old version of jQuery.
Thirdly, you were trying to select an element with an ID that already existed, and ID's can only exist one time. I've changed it to a class in the updated example.
Lastly, you were defining the class of the link twice like this:
<a class='float-left' id="deletethis" href='#' class="deletethis">Delete</a>
That also gave a problem, so I changed it to correct markup like this:
<a class='float-left deletethis' href='#'>Delete</a>
Good luck :) I've updated your jsFiddle here:
http://jsfiddle.net/q4pf6/
I've generated some divs with .append() method.
Code looks like that:
$("#someDiv").prepend("<div id='someId' class='myClass'></div>"):
$("#someDiv").prepend("<div id='someId2' class='myClass'></div>"):
that works great, now, i want to use that divs id's.
i'm trying to do it this way:
$(".myClass").click(function(){
alert($(this).attr('id'));
})
but, it does not work, help me please.
If the elements are dynamically generated, you probably need to delegate the event to an element that actually exists when binding the handler, something like:
$(function() {
$("#someDiv").on("click", ".myClass", function(){
alert(this.id);
});
});
And you'll need to replace the colon on the end of you're prepends with a semicolon to make those work.
FIDDLE
The problem maybe because you are binding the click event to "myClass" before actually adding the divs. Try placing the click event code after the code for adding new divs like this
$("#someDiv").prepend("<div id='someId' class='myClass'></div>"):
$("#someDiv").prepend("<div id='someId2' class='myClass'></div>"):
$(".myClass").click(function(){
alert($(this).attr('id'));
})
I'm new to javascript and JQuery, and I'm working in a small project with JSP.
I create a grid dynamically with JSP and I added some buttons wich class is "select" and in the alt attribute I set the current row index. That works perfectly, I'm trying to set the onclick dynamically. This is my code
$('.select').click(function (){
alert($('.select').attr('alt'));
}
I want to each button to show its own index, but that code shows just the first index in each button. I've searched how to do it, but nothing comes out.
Is there a chance to do what I want?
change this line as:
alert($(this).attr('alt'));
When jQuery calls your event handler it sets this to be the DOM element in question, so try this:
$('.select').click(function (){
alert($(this).attr('alt'));
});
If you need to access DOM element properties you can then get them directly, e.g.:
alert( this.id );
this.value = "test";
If you need to use jQuery methods on the element you need to pass it to the jQuery function first, e.g.:
$(this).hide();
$(this).css("color","red").slideDown();
$('.select').click(function (){
alert($(this).attr('alt'));
});
Change
alert($('.select').attr('alt'));
by
alert($(this).attr('alt'));
Now you select the attr alt of the button lauch the event.
Not sure if that's what you're looking for but...
$('.select').click(function() {
$('.select').each(function() {
$(this).attr('value', $(this).attr('alt'));
});
});
This'll have every button "show" the value stored within their alt attribute when you click one button.
By the way, if you're using 1 button per row, you'd probably better go with index().
I have a dropdown function that I need to work only on the div clicked, not all (I have 14+ of the same classes on the page that need to be displayed when a certain one is clicked)
At the moment my jQuery is as follows.
$('.qacollapsed').hide();
$('.qa').click(function () {
$('.qacollapsed').slideToggle();
$(this).toggleClass('active');
});
Of course, that is toggling all qacollapsed classes when there is 14 on the page (Q&A)
Is there a way for it to only drop down the one that is clicked?
the HTML
<div class="qa">
<h4 class="question"> </h4>
</div>
<div class="qacollapsed">
<p> </p>
</div>
It would be helpful to provide a snippet of HTML here, but I'll take a guess at the structure of your markup for now..
Instead of referencing all .qacollapsed elements, you need find elements that are close to the .qa that was clicked, e.g.:
$('.qa').click(function () {
$(this) // start with the clicked element
.find('.qacollapsed') // find child .qacollapsed elements only
.slideToggle();
$(this).toggleClass('active');
});
This will work if .qacollapsed is inside .qa - if not, you might need to use next (for siblings), or one of the other jQuery tree traversal methods.
Yo could find() it or use this as a context in the selector to choose only a descendent of the clicked object
$('.qa').click(function () {
$('.qacollapsed', this).slideToggle();
//You could do $(this).find('.qacollapsed').slideToggle();
$(this).toggleClass('active');
});
Check out the jQuery selectors and why not just use $(this)?
$('.qacollapsed').hide();
$('.qa').click(function () {
$(this).toggleClass('active').next().slideToggle();
});
Personally, I'd give all the divs IDs, the clickable bit being the ID of the question in the database for example, and the answer just being id='ID_answer' or something, then use jquery to slide in the div with the id corresponding to the link clicked, ie
Var showIt = $(this).attr('id') + '_answer'
$('.qacollapsed').not('#'+showIt).hide();
$('#'+showIt).slideToggle;
That will hide all the divs without that ID and show the required one.
Dexter's use of .next above looks simpler though, I've not tried that as being relatively new to jquery too.
