Use the same button to trigger two different JQuery events - javascript

I am trying to use the same button to trigger an ajax call to add a database entry if it is clicked and then trigger a different ajax call to remove the entry it is clicked again.
I have tried using toggleClass and although the button class does change and it's appearance changes accordingly the function still thinks it has the old class name.
$(document).ready(function() {
$(".selected").on("click", function() {
$(this).text(function (i, oldText) {
return $.trim(oldText) == 'Use Image' ? 'Selected' : 'Use Image';
});
$(this).toggleClass('selected selected_btn');
});
$(".selected").on("click", function() {
alert('selected');
});
$(".selected_btn").on("click", function() {
alert('de selected');
});
});
With the present code the alert is always 'selected'.

$(document).ready(function() {
$(".selected_btn").on("click", function() {
$(this).text(function (i, oldText) {
return $.trim(oldText) == 'Use Image' ? 'Selected' : 'Use Image';
});
$(this).toggleClass('selected');
if($(this).hasClass("selected"))
alert("Selected")
else
alert("de-Selected")
});
});
here is a fiddle:
http://fiddle.jshell.net/prollygeek/3LLN2/

Here is a simple and readable example on how to do this:
$(document).ready(function() {
$('.select-img').on('click', function(){
var $el = $(this);
var isSelected = $el.attr('data-selected');
if( isSelected != 'true' ){
firstFn();
$el.html('Use Image').attr('data-selected', true)
}else{
secondFn();
$el.html('Select').attr('data-selected', false)
}
})
var firstFn = function(){
alert('first thing to do');
}
var secondFn = function(){
alert('second thing to do');
}
})
Demo

Use *Class functions:
hasClass
removeClass
addClass
Working code:
$("a").on("click", function() {
if($(this).hasClass("bob")) {
// do delete
alert("delete");
$(this).removeClass("bob");
} else {
// do insert
alert("insert");
$(this).addClass("bob");
}
});
Demo

$(".selected").on("click", function() {
alert('selected');
});
Overrides the event you put on the beginning of the document.ready, I think.
(might not be true, but I think it is)

Onchange not working on next page Datatable

I am using checkbox on every row to do multi delete record in datatable. I want to show delete button only if any checkbox is checked. On first page, onchange is working. But on second page so on, onchange not working.
Below is my code :
$(".isdt-selected").on("change", function() {
$(".isdt-selected").each(function(index, elem) {
if($(elem).is(':checked')){
$('#btn-delete-bulk').show();
return false;
}else{
$('#btn-delete-bulk').hide();
}
});
});
I solved it with below code :
"drawCallback": function(settings) {
$(".isdt-selected").on("change", function() {
$(".isdt-selected").each(function(index, elem) {
if($(elem).is(':checked')){
$('#btn-delete-bulk').show();
return false;
}else{
$('#btn-delete-bulk').hide();
}
});
});
I saw the reference from here https://datatables.net/reference/option/drawCallback
Try this:
$(document).ready(function(){
$(".isdt-selected").on("change", function() {
$(".isdt-selected").each(function(index, elem) {
if($(elem).is(':checked')){
$('#btn-delete-bulk').show();
return false;
}else{
$('#btn-delete-bulk').hide();
}
});
});
});

Target last visible div after js action?

Is it possible to target the last visible div/container after a js function has worked, in this case mixitup plugin. You click to filter your results, this adds display: none or display: inline-block to the appropriate containers.
Using this code from another stack question
$(function () {
var $items = $($(".partners_list.container article.mix").get().reverse());
$items.each(function () {
if ($(this).css("display") != "none") {
$(this).addClass("red");
return false;
}
});
});
It works but only when the page first loads, after you active the mixitup and filter some results it doesn’t add the class red to the last ‘visible’ container i assume because its already loaded and done its job..
The mix it function is as follows..
$(function(){
var $filterSelect = $('#FilterSelect'),
$container = $('#partner_container');
$container.mixItUp({
animation: {
enable: false
}
});
$filterSelect.on('change', function(){
$container.mixItUp('filter', this.value);
});
});
So essentially need it to fire based on when the display: none and display:inline-block appears and disappears on the page.
So I think if you wrap the code you want to fire again in a function you can then set it to fire on callback from the mixItUp and on first load.
So you'd have a function like this:
function updateDisplay() {
var $items = $($(".partners_list.container article.mix").get().reverse());
$items.each(function () {
if ($(this).css("display") != "none") {
$(this).addClass("red");
return false;
}
});
}
And then call it on first load like this:
$(function () {
updateDisplay();
});
And then edit your mixItUp declaration to call this function also on callback of mixItUp having finished:
$container.mixItUp({
animation: {
enable: false
},
callbacks: {
onMixEnd: function(){
alert('No items were found matching the selected filters.');
}
}
});
Hope that helps.
Thanks to shodaburp i’ve managed to figure it out with the callback function, god knows how must be a fluke.
The full code i have now and seems to work...
$(function(){
var $filterSelect = $('#FilterSelect'),
$container = $('#partner_container');
$container.mixItUp({
animation: {
enable: false
},
callbacks: {
onMixEnd: function(state){
var $items = $($(".partners_list.container article.mix").get().reverse());
$items.each(function () {
if ($(this).css("display") != "none") {
$(this).addClass("red");
return false;
}
});
}
}
});
$filterSelect.on('change', function(){
$container.mixItUp('filter', this.value);
});
});

Getting localStorage and adding class to divs

I have a question that is quite confusing.
Everytime I check a "checkbox", it gets the closest "div" and add the class "hilight" and "marked" and set an Item to LocalStorage called "marking".
When I switch from div 1 to 2, I remove the class "hilight", but i keep the class "marked".
I'm trying to get the LocalStorage, and add class "hilight" again to divs that has "marked"
JS Fiddle: http://jsfiddle.net/b4KgV/
HTML
1
2
<button class="1st">show 1st</button>
<button class="2nd">show 2nd</button>
JS
localStorage.clear();
$(document).on('click', ':checkbox', function () {
if ($(this).is(':checked')) {
$(this).closest("div").addClass('hilight marked');
localStorage.setItem("marking","yes");
}
else {
$(this).closest("div").removeClass('hilight marked');
}
});
$(".1st").on('click', function() {
$(".second").css('display','none');
$(".second").removeClass('hilight');
$(".first").css('display','block');
});
$(".2nd").on('click', function() {
$(".first").css('display','none');
$(".first").removeClass('hilight');
$(".second").css('display','block');
});
if (localStorage.getItem("marking")) {
$(".marked").closest("div").addClass('hilight');
};
Thx.
Localstorage goes by key:value as you know, I tried to keep them separate.
Try this fiddle
http://jsfiddle.net/b4KgV/11/
$(document).on('click', ':checkbox', function () {
var div = $(this).closest("div").attr("id")
if ($(this).is(':checked')) {
$(this).closest("div").addClass('hilight marked');
localStorage.setItem(div, true);
} else {
$(this).closest("div").removeClass('hilight marked');
localStorage.setItem(div, false);
}
});
$(".1st").on('click', function () {
console.log("test")
if (localStorage.getItem("firstDiv") == "true") {
$(".first").closest("div").addClass('hilight');
};
$(".second").css('display', 'none');
$(".second").removeClass('hilight');
$(".first").css('display', 'block');
});

On/off click event on alternating tabs

$('#filter').on('click', function(){
$('#sort').off('click');
console.log($(this));
});
$('#sort').on('click', function(){
$('#filter').off('click');
console.log($(this))
});
$('.close').on('click', function () {
console.log($(this));
$('#sort').on('click');
$('#filter').on('click');
});
Why doesnt the div .close give back the on method to the divs above if they have the same selector id?
EDIT: For clarity, I'm wanting to temporarily remove the on event on whichever of the two elements wasn't clicked (#filter or #sort). Then clicking '.close' will return the said element back to having the on method again.
The off() does not work the way you think. It actually removes the event handlers (callback functions), not just hides them, so you cannot restore them with a simple on(), they are not stored any longer by the element after the off(), you have to add them again. It is not easy to track whether an event handler is added, so I suggest another approach.
var sort = true;
var filter = true;
$('#filter').on('click', function(){
if (!filter)
return;
sort = false;
console.log($(this));
});
$('#sort').on('click', function(){
if (!sort)
return;
filter = false;
console.log($(this))
});
$('.close').on('click', function () {
console.log($(this));
sort = true;
filter = true;
});
Another approach to use toggle() and combine it with the on() and off() functions. Hmm I found that jquery toggle() is not loosely coupled to dom elements, so you cannot do this with that. You have to create your own implementation, for example something like this:
function toggle(options) {
var currentValue = !!options.value;
return function (value){
if (value === undefined)
value = !currentValue;
if (value != currentValue)
if (value) {
currentValue = true;
options.on();
}
else {
currentValue = false;
options.off();
}
};
}
With this toggle implementation your code will be the following:
var switches = {
sort: toggle({
on: function (){
$('#sort').on('click', function(){
switches.filter(false);
console.log($(this))
});
},
off: function (){
$('#sort').off('click');
}
}),
filter: toggle({
on: function (){
$('#filter').on('click', function(){
switches.sort(false);
console.log($(this));
});
},
off: function (){
$('#filter').off('click');
}
})
};
$('.close').on('click', function () {
console.log($(this));
switches.sort(true);
switches.filter(true);
});
switches.sort(true);
switches.filter(true);
You can try with:
$('#filter:not(.off)').on('click', function(){
$('#sort').addClass('off');
console.log($(this));
});
$('#sort:not(.off)').on('click', function(){
$('#filter').addClass('off');
console.log($(this))
});
$('.close').on('click', function(){
$('#sort').removeClass('off');
$('#filter').removeClass('off');
console.log($(this));
});
I'm assuming that in your block of code…
$('.close').on('click', function () {
console.log($(this));
$('#sort').on('click');
$('#filter').on('click');
});
You want to click #sort and #filter. To do such, you'll need to do the following:
$('.close').on('click', function () {
console.log($(this));
$('#sort').click();
$('#filter').click();
});
Even so, it would probably be better to wrap the other event handlers in a function and call them like such:
$('.close').on('click', function () {
console.log($(this));
sortClickFunction();
filterClickFunction();
});
This will do anything: $('#sort').on('click');
You need to call: $('#sort').trigger('click');

Checkbox not working properly

Here is my piece of code in jquery actuall I want in such way where :
Where by default value of Ball will be shown in Textbox.
same time either All or Stopall will be work(it's not working here properly :( )
For multiple times checking All button,which is not working according to the expectation
here is the fiddle link : http://jsfiddle.net/bigzer0/PKRVR/11/
$(document).ready(function() {
$('.check').click(function(){
$("#policyName").val('Start');
$("#features").val('');
$('[name="startall"]').on('click', function() {
var $checkboxes = $('input[type="checkbox"]').not('[name="startall"], [name="stopall"]');
if (this.checked) {
$checkboxes.prop({
checked: true,
disabled: true
});
}
else{
$checkboxes.prop({
checked: false
});
}
});
$(".check").each(function(){
if($(this).prop('checked')){
$("#policyName").val($("#policyName").val() + $(this).val());
$("#features").val($("#features").val() + $(this).data('name'));
}
});
});
});
Any comments on this context will be welcome
You're code is broken in many ways. You are binding a click event inside a click event. You should take that outside and just make sure it's inside the document.ready function since your element is a static element.
$(document).ready(function() {
// cache features
var $features = $('#features');
// cache policyname
var $policy = $("#policyName");
// cache all/stopall
var $ss = $('[name="startall"],[name="stopall"]');
// cache all others
var $checkboxes = $('input[type="checkbox"]').not($ss);
// function to update text boxes
function updateText() {
var policyName = 'Start';
var features = '';
// LOOP THROUGH CHECKED INPUTS - Only if 1 or more of the 3 are checked
$checkboxes.filter(':checked').each(function(i, v) {
policyName += $(v).val();
features += $(v).data('name');
});
// update textboxes
$policy.val(policyName);
$features.val(features);
}
$checkboxes.on('change', function() {
updateText();
// check startall if all three boxes are checked
$('input[name="startall"]').prop('checked', $checkboxes.filter(':checked').length == 3);
});
$('input[name="startall"]').on('change', function() {
$checkboxes.prop({
'checked': this.checked,
'disabled': false
});
updateText();
});
$('input[name="stopall"]').on('change', function() {
$checkboxes.add('[name="startall"]').prop({
'checked': false,
'disabled': this.checked
});
updateText();
});
// updatetext on page load
updateText();
});​
FIDDLE
you are checking click function in click function. you should use if statement.
