I have a table. Each column has a button at the top. If the td elements below within the column have content in them, then hide the button. If not then display the button and onClick add class active too the td element.
$(document).ready(function (){
$('.button-fill').on("click", function() {
var i=$(this).parent().index();
if($(this).closest("tr").siblings().find("td:eq("+i+")").text()=="")
$(this).hide();
else
$(this).show();
});
<!-- Fill in the td -->
$('.button-fill').on("click", function() {
var i=$(this).parent().index();
$(this).closest("tr").siblings().find("td:eq("+i+")").addClass("active");
//});
});
});

I've created a jsfiddle. I don't know what i'm doing wrong? Thank you
Since you have bind the button toggle logic inside button click - you will always have the button in the starting. When you will click on the button only then it will first hide the button and then make the content active.
In case you want this behavior in the starting as soon as the page loads, you should change below line (the 2nd line in your code) from your code -
$('.button-fill').on("click", function() {
to
$('.button-fill').each( function(i,e) {
also, you should not use <!-- Fill in the td --> style of commenting in JavaScript.
I can see you are having two "click" event handler on same class. Instead of it, you can merge it as well.
Here is the optimized version of your code :
JavaScript :
$(document).ready(function (){
$('.button-fill').on("click", function() { //Only one click event handler
var $this = $(this);
var i=$this.parent().index();
var $trSibling = $this.closest("tr").siblings();
$this.toggle($trSibling.find("td:eq("+i+")").addClass("active").text() != ""); //adds the class as well and check the text as well.
})
$(".button-fill").trigger("click");
// explicitly clicking on button to make sure that initially button should not be shown if column text is not empty
});

Is this the same what you want?
#Vijay has the right answer, but as a side note, you need to change this:
if($(this).closest("tr").siblings().find("td:eq("+i+")").text()=="")
to this
if($(this).closest("tr").siblings().find("td:eq("+i+")").text()!="")
if you want to hide the button when there is content, instead of the other way around (notice the != near the end).

I have a series of custom Chevron elements that I'm going to use as buttons on my site. I've managed to set up the jQuery so that the clicked chevron/button is given a class="selected" which I then use to add custom styles. If I click any other chevron then the selected class is removed from the first chevron and added to the last chevron that was clicked. All of this works fine. I have another link that can be clicked to remove the class from all of the chevrons. What I'm trying to do now is to enable the .toggle(Class) function on jQuery so that I can also remove the class="selected" by clicking the same element twice.
My jQuery code:
$(function () {
$('#chevrons > ul > li > a').click( function(){
$('#chevrons .selected').removeClass('selected');
$('#show-all').removeAttr("style");
$(this).toggleClass('selected');
});
});
$(function () {
$('#show-all').click( function(){
$('#chevrons .selected').removeClass('selected');
$(this).css('color', '#FECF2A');
});
});
I've tried the toggle without the rows:
$('#chevrons .selected').removeClass('selected');
$('#show-all').removeAttr("style");
And it works fine. I assumed (perhaps incorrectly) that the jQuery would execute line-by-line and therefore the last thing to execute. But perhaps the first line above is removing the "selected" attribute from all of the chevrons and then the last line will only ever add the class.
What am I doing wrong here?
JSFiddle: http://jsfiddle.net/oqs4nycj/1/
Just exclude the clicked item from the class removal using not():
$('#chevrons .selected').not(this).removeClass('selected');
Applying this fix to your own JSFiddle (looks very cool by the way) you get this:

Edit. I did not read the question carefully enough. Sorry. I have edited the code to deselect by clicking twice.
jQuery(function ($) {
// Variables are your friends - the $ preface tells us its a jQuery object
var $chevrons = $("#chevrons");
var $buttons = $chevrons.find('a');
var $show_all = $('#show_all');
// We bind a handler to the parent $chevrons element
// this is good for performance
// It will also bind the handler to elements dynamically added with ajax.
$chevrons.on('click', 'a', function(e){
var $old_selection = $buttons.filter('.selected');
var $clicked = $(this);
// Ensure that no button is selected
$buttons.removeClass('selected');
// Checks if button already was selected.
if ($clicked.get(0) !== $old_selection.get(0)) {
// select the clicked button
$clicked.addClass('selected');
}
$show_all.removeClass('active');
// prevents the browser from scrolling to top.
e.preventDefault();
});
$show_all.on('click', function(){
$buttons.removeClass('selected');
$(this).addClass('active');
});
});
I am trying to make and area on my page selectable, but inside there is a radiobutton which i dont want to be part of the selectable area. I have it setup at the moment to allow the user select the area but this also includes the radiobutton:
$(document).ready(function () {
jQuery(document).on('click', 'label[title^="id_"]', function(e) {
$(this).addClass('hide');
var current = "s_" + $(this).attr('title');
$("label[title='" + current + "']").removeClass('hide');
});
});
This basic idea of the code at the moment is hide the selected div and show another. What i want is to exclude the radiobuttons inside this div from the click event.
I tried this: but it prevents clicking of the radiobuttons
if ($(e.target).is('input[type="radio"]')) {
e.preventDefault();
return;
}
As said by Jon in comments(and also my personal answer)
Your code should be:
if ($(e.target).is('input[type="radio"]')) {
return;
}
Put that in opening of the function body of the click event handler.
The return call, will terminate the function so it wont progress further.
I have following JsFiddle for editing a Div, now I some how want too add a div which in edit mode by default.
When i click on Add New div,new div is added and then it can be edited by clicking Edit .
But i was wondering is there a way when i click on ADD New Div the div should be by default in Edit mode. Is there any way i can achieve it.
Following is Js Fiddle
Thanks For Help :)
Change your function as follows:
$("#add").click(function () {
$('#accordion').prepend($("#appendpanel").clone().removeAttr('id').find('.panel-title, .panel-collapse').attr('contenteditable',true).css('border','2px solid'));
});
check this JSFiddle
Updated Fiddle as per comments
Note:
There are other neat ways for doing what you want.
You can simply keep a hidden editable div, add its clone and make it visible..
Or create a function that dynamically adds the mark up you need..
Side notes: Please avoid using inline-css, here is why: Why Use CSS # MDN
for changing style attributes jQuery has a dedicatedcss() function
You don't need two $(document).ready() functions
Not a one-liner, but does the job ;)
$("#add").click(function () {
var clone = $("#appendpanel").clone().removeAttr('id');
$('#accordion').prepend(clone);
// trigger a click event on the button, which makes the required div's content-editable
clone.find("#edit1").trigger("click");
});
Updated fiddle
Updated:
Use this code in $('#accordion').on('click', '.delete-link', function () {
var children = $(".panel");
// get those not hidden
children = children.filter(
function(index){
return children.eq(index).css("display") !== "none";
}
).length;
if(children === 1){ // the only child left is "Add new div"
$("#message").show(500);
}
And this in $("#add").click(function () {
$("#message").hide(500);

I am using jQuery to dynamically add elements every time a user clicks a link (".add-event"). Also included in this element is a icon to remove the entire element if the user chooses. I want to hide or disable this remove icon if the element is the last left on the page. This is what I have tried so far:
$(document).on('click','.close_box2:only-child',function(){
event.preventDefault();
});
AND
if( $('.event').length===1) {
$('.close_box2').hide()
}
HTML:
<div class="event">
<span class="close_box2"><i class="icon-remove"></i></span>
<span class="add-event">Add Event</span>
</div>
What am I doing wrong!? Thanks
JSFiddle: http://jsfiddle.net/TrueBlueAussie/KPY9r/6/
You just want to check for the "last one" inside the delete handler:
// initial hide of sole close button
$('.close_box2').hide();
// On add, clone the template and show all close buttons
$(document).on('click', '.add-event', function () {
// Create a new event based on the template
$('#events').append($('#template').html());
// Show all close buttons (as we must now have > 1 event)
$('.close_box2').show();
});
$(document).on('click', '.close_box2', function (e) {
$(this).closest('.event').remove();
// Is there only one left?
if ($('.event').length === 1) {
// Hide the close box on the last event
$('.close_box2').hide()
}
});
Notes:
I use a dummy <script> element to hold you HTML template. This is better than cloning an element on the page and much better than inline HTML strings in your code.
The following looks better regarding performance:
$('.close_box2:only-child').on('click', function(event){
event.preventDefault();
});
I am adding the form my current list in a div box at the bottom of the table.
I am appending the div box when someone clicks on add button.
But when i click add button multiple times , then many div boxes are appended.
Is there any way that no matter how many times I click the button, only one instance gets append to div box.
This is my code
$var = $(this).parent().parent();
$var.append($('.jq_div')[0].outerHTML);
attach your listener using .one().
$("button").one('click', function(){
// Your code
});

This is under the assumption that you're using jQuery 1.7+
One simple solution would be having a boolean flag that you can toggle once your button is clicked. Additionally, there is actually a jQuery function that provides this exact functionality.
It's called one() -
Attach a handler to an event for the elements. The handler is executed
at most once per element.
So your code would look something like this -
$("#someTrigger").one('click', function(){
$var = $(this).parent().parent();
$var.append($('.jq_div')[0].outerHTML);
});
The boolean method is also very simple -
var wasClicked = false;
$("#someTrigger").on('click', function(){
if (wasClicked == false){
// append your form
wasClicked = true;
}
});
