I have a javascript method that has 2 parameters, the first is the ID of a tr element, the other is an actual div. My add/remove class jQuery method works fine for the first item (which I get with a jQuery selector). However it throws a javascript error when I use it on the passed in Div.
onclick="ToggleTicketDetails('ticketDetails_#(ticket.TicketID)', this);"
I can obviously use a jQuery selector on the div to fix this, however I would like to know why it behaves this way.
function ToggleTicketDetails(detailsId, divSender) {
//alert(divSender);
var element = $('#' + detailsId);
//alert(element);
if (element.hasClass("TicketDetailsOff")) {
element.removeClass("TicketDetailsOff").addClass("TicketDetailsOn");
divSender.removeClass("DivAsExpand").addClass("DivAsCollapse");
}
else {
element.removeClass("TicketDetailsOn").addClass("TicketDetailsOff");
divSender.removeClass("DivAsCollapse").addClass("DivAsExpand");
}
}
divSender is DOM element. Use jquery object $(divSender) to apply removeClass and addClass on this like below.
function ToggleTicketDetails(detailsId, divSender) {
var element = $('#' + detailsId);
if (element.hasClass("TicketDetailsOff")) {
element.removeClass("TicketDetailsOff").addClass("TicketDetailsOn");
$(divSender).removeClass("DivAsExpand").addClass("DivAsCollapse");
}
else {
element.removeClass("TicketDetailsOn").addClass("TicketDetailsOff");
$(divSender).removeClass("DivAsCollapse").addClass("DivAsExpand");
}
}

How to can we add/Remove :after class to div using jQuery
let say I have following class
.vignetteC1:after { ... }
.vignetteC2:after { ... }
.vignetteC3:after { ... }
.vignetteC4:after { ... }
.vignetteC5:after { ... }
if we want to add after class to a dive using jQuery how can we do so. ?
I have googled a lot but I am only getting an example of .after function and so on.
I have tried the following but it not working
var VignetteVal = 'vignetteC' + value + ':after';
for (var i = 1; i <= 5; i++) {
Img.parent().removeClass(('vignetteC' + i + ':after'));
}
Img.parent().addClass(VignetteVal);
But the above code add vignetteC2: after class to div
like
<div class="vignetteC2: after">
You are very confused about what :after is. It's a pseudo-element. It is NOT a class and not part of the DOM structure so it cannot be edited or added with javascript.
Read more here > https://www.w3schools.com/css/css_pseudo_elements.asp
:after pseudo-element adds content after the content of an element. It is not a class. To add content after an element you can use insertAfter() or you can use append to add content at the end of the current element. Also, there is an after() method
insertAfter()
append()
after()
As you can see below $(nextDiv + ' > div').eq(i).fadeIn('slow'); does not work as it seems to be malformed. nextDiv is on inspection the div below the anchor, how do I achieve getting the two divs that sit inside it?
HTML:
Sub Click
<div>
<div>I want this to fade in on the click</div>
<div>Followed by this etc.</div>
</div>
Javascript:
function subClick(myAnchor)
{
var nextDiv = $(myAnchor).next();
function showDiv(i) {
if (i > 2) return;
setTimeout(function () {
$(nextDiv + ' > div').eq(i).fadeIn('slow');
showDiv(++i);
}, 50);
}
showDiv(0);
}
You are trying to concatenate a string with jQuery, that won't provide a valid selector. The concatenation would provide something like "[object Object] > div" which doesn't select any elements in your code.
Instead, get the div children using children() method on the jQuery nextDiv object.
nextDiv.children('div').eq(i).fadeIn('slow');
If there are only two divs then you can reduce the code using delay() method.
function subClick(myAnchor) {
var nextDivs = $(myAnchor).next().children();
// if you want to do the animation after the first then
// use the below code, where second animation initializing within
// the first animation success callback, which also provides a 50ms
// delay for second animation(avoid .delay(50) if you dont nedd that delay)
// nextDivs.eq(0).fadeIn('slow', function() {
// nextDivs.eq(1).delay(50).fadeIn('slow');
// });
// in case you just want to provide a 50ms delay
// between animation then use, your code does this
nextDivs.eq(0).fadeIn('slow');
nextDivs.eq(1).delay(50).fadeIn('slow');
}
var nextDiv = $(myAnchor).next(); then nextDiv is an object not a selector. If you want to access its div children use this:
nextDiv.children('div').eq(i).fadeIn('slow');
EDIT: I cleaned up the code a bit and narrowed down the problem.
So I'm working on a Wordpress site, and I'm trying to incorporate drop-downs into my menu on mobile, which means I have to use jQuery to assign classes and id's to my already existing elements. I have this code that already works on premade HTML, but fails on dynamically created id's.
Here is the code:
...
var menuCount = 0;
var contentCount = 0;
//find the mobile menu items
var submenus = $('[title="submenu"]');
if (submenus.length && submenus.parent('.fusion-mobile-nav-item')) {
console.log(submenus);
submenus.addClass('dropdown-title').append('<i id="dropdown-angle" class="fa fa-angle-down" aria-hidden="true"></i>');
submenus.each(function() {
$(this).attr("href", "#m" + menuCount++);
})
var content = submenus.parent().find('ul.sub-menu');
content.addClass('dropdown-content');
content.each(function() {
$(this).attr("id", "m" + contentCount++);
})
}
$(document).on('click', '.dropdown-title', function(e) {
var currentAttrValue = $(this).attr('href');
if ($(e.target).is('.d-active') || $(e.target).parent('.dropdown-title').is('.d-active')) {
$(this).removeClass('d-active');
$(currentAttrValue).slideUp(300).removeClass('d-open');
} else {
$('.dropdown-title').removeClass('d-active');
$('.dropdown-content').slideUp(300).removeClass('d-open');
$(this).addClass('d-active');
console.log($(currentAttrValue));
//THIS LINE FAILS
$(currentAttrValue).slideDown(300).addClass('d-open');
}
e.preventDefault();
});
I've registered the elements with the class dropdown-title using $(document).on(...) but I can't figure out what I need to do to register the elements with the custom ID's. I've tried putting the event callback inside the .each functions, I've tried making custom events to trigger, but none of them will get the 2nd to last line of code to trigger. There's no errors in the console, and when I console log the selector I get this:
[ul#m0.sub-menu.dropdown-content, context: document, selector: "#m0"]
0
:
ul#m0.sub-menu.dropdown-content
context
:
document
length
:
1
selector
:
"#m0"
proto
:
Object[0]
So jQuery knows the element is there, I just can't figure out how to register it...or maybe it's something I'm not thinking of, I don't know.
If you are creating your elements dynamically, you should be assigning the .on 'click' after creating those elements. Just declare the 'on click' callback code you posted after adding the ids and classes instead of when the page loads, so it gets attached to the elements with .dropdown-title class.
Check this jsFiddle: https://jsfiddle.net/6zayouxc/
EDIT: Your edited JS code works... There also might be some problem with your HTML or CSS, are you hiding your submenus? Make sure you are not making them transparent.
You're trying to call a function for a attribute, instead of the element. You probably want $(this).slideDown(300).addClass('d-active'); (also then you don't need $(this).addClass('d-active'); before)
Inside submenus.each loop add your callback listener.
As you are adding the class dropdown-title dynamically, it was not available at dom loading time, that is why event listener was not attached with those elemnts.
var menuCount = 0;
var contentCount = 0;
//find the mobile menu items
var submenus = $('[title="submenu"]');
if (submenus.length && submenus.parent('.fusion-mobile-nav-item')) {
console.log(submenus);
submenus.addClass('dropdown-title').append('<i id="dropdown-angle" class="fa fa-angle-down" aria-hidden="true"></i>');
submenus.each(function() {
$(this).attr("href", "#m" + menuCount++);
// add callback here
$(this).click( function(e) {
var currentAttrValue = $(this).attr('href');
if ($(e.target).is('.d-active') || $(e.target).parent('.dropdown-title').is('.d-active')) {
$(this).removeClass('d-active');
$(currentAttrValue).slideUp(300).removeClass('d-open');
} else {
$('.dropdown-title').removeClass('d-active');
$('.dropdown-content').slideUp(300).removeClass('d-open');
$(this).addClass('d-active');
console.log($(currentAttrValue));
$(currentAttrValue).slideDown(300).addClass('d-active');
}
e.preventDefault();
});
})
var content = submenus.parent().find('ul.sub-menu');
content.addClass('dropdown-content');
content.each(function() {
$(this).attr("id", "m" + contentCount++);
})
}
Turns out my problem is that jQuery is adding to both the mobile menu and the desktop menu, where the desktop menu is being loaded first when I search for that ID that's the one that jQuery finds. So it turns out I was completely wrong about my suspicions.
Since I want to use classes instead of id's in these functions(I have three of the same function with different things I want to .append) I am sure I need to put $(this) in those functions somewhere to only trigger only ONE function on button click and not all three of them. but I am not sure because I am a total beginner in jquery/js, so I would appreciate some help.
$(document).ready(function () {
$(".onclick").click(function () {
$('#favorites').append('<div data-role="main"class="ui-content"><div class="ui-grid-b"><div class="ui-block-a">Arrow</div><div class="ui-block-b">More Info</div><div class="ui-block-c">Unfavorite</div></div></div>');
});
});
http://codepen.io/anon/pen/JYxqEw - HTML And the Jquery Code
$('.onclick') selects all the elements with a class of onclick. That means that, whenever something with class="onclick" is clicked, that function will fire.
If you want all of those elements to append that exact HTML to the #favorites element, then you can leave your code as-is.
However, if what you're trying to do is append that html to the clicked element, that is when you'd use $(this) -- that selects the element you clicked with jQuery, then you can append directly to that element ie:
$(document).ready(function () {
$(".onclick").click(function () {
// this will append the HTML to the element that triggered the click event.
$(this).append('<div data-role="main"class="ui-content"><div class="ui-grid-b"><div class="ui-block-a">Arrow</div><div class="ui-block-b">More Info</div><div class="ui-block-c">Unfavorite</div></div></div>');
});
});
EDIT
so to insert the contents of each .onclick into #favorites, you'll need to use the innerHTML value of the DOM node. example fiddle:
http://jsbin.com/qazepubuzu/edit?html,js,output
When you select something with jQuery, you're actually getting back not just the DOM node, but a jQuery object -- this object contains both a reference to the actual DOM node ([0]), as well as a jquery object ([1]).
So to select the DOM node with $(this), you target the node: $(this)[0]. Then you can use .innerHTML() to grab the HTML contents of the node and do as you like.
Final result:
$(function () {
$('.onclick').click(function () {
$('#favorites').append( $(this)[0].innerHTML );
});
});
So the building blocks are not that complex, but I think you're a novice jQuery developer and so you may not be clear on the difference between jQuery and JS yet.
$(selector, context) allows us to create a jQuery collection for a CSS selector which is the child of a current context DOM node, though if you do not specify one there is an automatic one (which is document.body, I think). Various functions iterating over jQuery collections make the particular element available as this within the JavaScript. To get to the strong element from the .onclick element in the HTML fragment you need to travel up in the hierarchy, then to the appropriate element. Then, we can collect the text from the element. We can do this in either JS or jQuery.
To do this with simply jQuery:
// AP style title case, because Chicago is too crazy.
var to_title_case = (function () { // variable scope bracket
var lower_case = /\b(?:a|an|the|and|for|in|so|nor|to|at|of|up|but|on|yet|by|or)\b/i,
first_word = /^(\W*)(\w*)/,
last_word = /(\w*)(\W*)$/;
function capitalize(word) {
return word.slice(0, 1).toUpperCase() + word.slice(1).toLowerCase();
}
function capitalize_mid(word) {
return lower_case.exec(word) ? word.toLowerCase() : capitalize(word);
}
return function to_title_case(str) {
var prefix = first_word.exec(str),
str_minus_prefix = str.slice(prefix[0].length),
suffix = last_word.exec(str_minus_prefix),
center = str_minus_prefix.slice(0, -suffix[0].length);
return prefix[1] + capitalize(prefix[2]) + center.replace(/\w+/g, capitalize_mid)
+ capitalize(suffix[1]) + suffix[2];
};
})();
$(document).ready(function() {
$(".onclick").click(function () {
var text = $(this).parents('.ui-grid-a').find('.ui-block-a').text();
var html = '<div data-role="main"class="ui-content">'
+ '<div class="ui-grid-b"><div class="ui-block-a">'
+ to_title_case(text) + '</div><div class="ui-block-b">More Info</div>'
+ '<div class="ui-block-c">Unfavorite</div></div></div>';
$("#favorites").append(html);
});
});
I found a response in a jquery forum and they made a function to do this but the result is not the same.
Here is an example that I created for an image button:
var buttonField = $('<input type="image" />');
buttonField.attr('id', 'butonFshi' + lastsel);
buttonField.val('Fshi');
buttonField.attr('src', 'images/square-icon.png');
if (disabled)
buttonField.attr("disabled", "disabled");
buttonField.val('Fshi');
if (onblur !== undefined)
buttonField.focusout(function () { onblur(); });
buttonField.mouseover(function () { ndryshoImazhin(1, lastsel.toString()); });
buttonField.mouseout(function () { ndryshoImazhin(0, lastsel.toString()); });
buttonField.click(function () { fshiClicked(lastsel.toString()); });
And I have this situation:
buttonField[0].outerHTML = `<INPUT id=butonFshi1 value=Fshi src="images/square-icon.png" type=image jQuery15205073038169030395="44">`
instead the outer function I found gives buttonField.outer() = <INPUT id=butonFshi1 value=Fshi src="images/square-icon.png" type=image>
The function is:
$.fn.outer = function(val){
if(val){
$(val).insertBefore(this);
$(this).remove();
}
else{ return $("<div>").append($(this).clone()).html(); }
}
so like this I loose the handlers that I inserted.
Is there anyway to get the outerHTML with jquery in order to have it cross-browser without loosing the handlers ?!
You don't need convert it to text first (which is what disconnects it from the handlers, only DOM nodes and other specific JavaScript objects can have events). Just insert the newly created/modified node directly, e.g.
$('#old-button').after(buttonField).remove();`
after returns the previous jQuery collection so the remove gets rid of the existing element, not the new one.
Try this one:
var html_text = `<INPUT id=butonFshi1 value=Fshi src="images/square-icon.png" type=image jQuery15205073038169030395="44">`
buttonField[0].html(html_text);
:)
Check out the jQuery plugin from https://github.com/darlesson/jquery-outerhtml. With this jQuery plugin you can get the outerHTML from the first matched element, replace a set of elements and manipulate the result in a callback function.
Consider the following HTML:
<span>My example</span>
Consider the following call:
var span = $("span").outerHTML();
The variable span is equal <span>My example</span>.
In the link above you can find more example in how to use .outerHTML() plug-in.
This should work fine:
var outer = buttonField.parent().html();
