jQuery | From jQuery to native javascript - javascript

I'm looking for the way to translate this block of code from jQuery to pure javascript. Is it possible?
jQuery(".menu2").each(function(){
$menu = jQuery(this);
$menu.find("li").unbind('mouseenter mouseleave').filter(".deeper").children("span.separator").addClass("parent");
$menu.find("li.deeper>a.parent, li.deeper>span.separator").unbind('click').bind('click', function(e) {
e.preventDefault();
jQuery(this).parent("li").children("ul").animate({height: 'toggle'}, 300, "jswing");
});
$menu.find("li a.parent > span.linker").click(function(){
if((typeof jQuery(this).parent().attr("href") != 'undefined') && jQuery(this).parent().attr("href") != "#"){
jQuery(this).parent().unbind('click');
myLink = jQuery(this).parent().attr("href");
window.location.href = myLink;
}
});
}
Thanks!

Of course it's possible. Whether it's a good idea or not is debatable, but here...
[].forEach.call(document.querySelectorAll(".menu2"),function(menu){
[].forEach.call(menu.getElementsByTagName("li"),function(li) {
li.__events = li.__events || {};
if( li.__events.mouseenter) {
li.removeEventListener('mouseenter',li.__events.mouseenter);
delete li.__events.mouseenter;
}
if( li.__events.mouseleave) {
li.removeEventListener('mouseleave',li.__events.mouseleave);
delete li.__events.mouseleave;
}
if( li.className.match(/\bdeeper\b/)) {
[].forEach.call(li.querySelectorAll("span.separator"),function(span) {
if( !span.className.match(/\bparent\b/)) span.className += " match";
});
}
});
[].forEach.call(menu.querySelectorAll("li.deeper>a.parent, li.deeper>span.separator"),function(elem) {
elem.__events = elem.__events || {};
if( elem.__events.click) {
elem.removeEventListener('click',elem.__events.click);
delete elem.__events.click;
}
elem.addEventListener('click',elem.__events.click = function(e) {
[].forEach.call(this.parentNode.getElementsByTagName('ul'),function(ul) {
if( ul.style.height == "auto") ul.style.height = "0px";
else ul.style.height = "auto";
// TODO: Implement animation here
});
return false;
},false);
});
[].forEach.call(menu.querySelectorAll("li a.parent>span.linker"),function(elem) {
elem.__events = elem.__events || {};
if( elem.__events.click) {
elem.removeEventListener('click',elem.__events.click);
delete elem.__events.click;
}
elem.addEventListener('click',elem.__events.click = function(e) {
if( this.parentNode.getAttribute("href") != "#") {
window.location.href = this.parentNode.href;
}
return false;
},false);
});
});
... I think it's fairly obvious why people use jQuery. Of course, I would have my own toolbox to make a lot of this code easier to manage ;)

But when i compile it with ng build --prod it's gives TypeError: $(...).multiple_emails is not a function , if it's not working correctly any other tool to convert from JavaScript to typescript ?
i had convert js into typesript using online compiler but nothing happened.
solved!!!!
finally i figure out the problem. it is in angular-cli.json.when i place my multiple_email.js after jquery-3.1.1.min.js,jquery.validate.min.js then it works like charm...!!! #rajesh thanks

CSS Float Form Pattern for WooCommerce Forms

I'm attempting to implement the float label pattern (https://webdesign.tutsplus.com/articles/implementing-the-float-label-form-pattern--webdesign-16407) for my WooCommerce forms.
The checkout from is here - https://dev.joshkern.co/checkout/.
You'll first need to add a product/service from here - https://dev.joshkern.co/wordpress-maintenance/. You'll see the form isn't working as it should. What am I missing?
This is my javascript:
(function($) {
$(document).ready(function(){
// Test for placeholder support
$.support.placeholder = (function(){
var i = document.createElement('input');
return 'placeholder' in i;
})();
// Hide labels on page load if placeholders are supported
if ($.support.placeholder) {
$('.woocommerce form .form-row').each(function(){
$(this).addClass('js-hide-label');
});
$('.woocommerce form .form-row').find('input, textarea').on('keyup blur focus', function(e){
// Cache our selectors
var $this = $(this),
$parent = $this.parent();
// Add or remove classes
if (e.type == 'keyup') {
if ($this.val() == '') {
$parent.addClass('js-hide-label');
}
else {
$parent.removeClass('js-hide-label');
}
}
else if (e.type == 'blur') {
if( $this.val() == '' ) {
$parent.addClass('js-hide-label');
}
else {
$parent.removeClass('js-hide-label').addClass('js-unhighlight-label');
}
}
else if (e.type == 'focus') {
if( $this.val() !== '' ) {
$parent.removeClass('js-unhighlight-label');
}
}
});
}
});
})(jQuery);

Create a javascript object

I would say I am fairly decent with javascript and jQuery, well, enough to get the job done and done pretty well.
I do however lack a deep understanding of js.
I have created some functions for highlighting table elements.
ctrl+click toggles selections
shift+click+drag highlights selection
My question does not pertain to whether or not my implementation is the best way or not but ...
How do I abstract this functionality so I can add this functionality to any table. Like if I add more highlighting features and such and put this in its own .js file. How would I attach it to any html table?
Sorry if this has already been answered, but I could not think of what to search for.
Thank you.
****Newest Code****
This code is in its own .js file and is attached to my table.
All the current functionality is there. The only thing I am weary of is the .off() functions. In my case, I am reloading new tables.... as I type this, I realize I should just empty the tr's from the table instead of recreating a new table all the time, then I could get rid of the .off() calls.

you can wrap all this in a function since you have some local variables related to individual selection
$.fn.addEvents = function(obj) {
var properties = $.extend(true, {
shifting: false,
ctrling: false,
mousing: false,
mouseenter: 0,
mouseleave: 0,
trajectory: null
}, obj || {});
return $(this)
.off('click')
.off('contextmenu')
.on('click', function() {
.....
})
.on('mouseleave', function(e) {
//rename your local variables with `properties.` prefix
properties.mouseleave = e.clientY;
if (properties.shifting && properties.mousing) {
tmptrajectory = properties.mouseenter - properties.mouseleave < 0 ? 1 : -1;
}
if ($(this).hasClass('selected') && properties.shifting && properties.mousing && properties.trajectory != null && properties.trajectory != tmptrajectory) {
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
....
});
}
usage
$('#datatablebody tr').addEvents({ shifting: false, ctrling: true }); //custom settings
$('#someother tr').addEvents(); //default settings
you could add that functionality to a class and add that class to the tables you want to affect...
Here I create the class .myTableBeh and all tables with that class will have the behaviour you programmed.
var shifting = false;
var ctrling = false;
var mousing = false;
var mouseenter = 0;
var mouseleave = 0;
var trajectory = null;
$('.myTableBeh tr')
.off('click')
.off('contextmenu')
.on('click', function()
{
if(!ctrling)
{
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
else if(ctrling && $(this).hasClass('selected'))
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}

$(this).addClass('selected');

}
})
.on('contextmenu', function(ev)
{
ev.preventDefault();
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
showContextMenuTR($(this).closest('tr').attr('id'), ev.clientX, ev.clientY);
return false;
})
.off('mousedown')
.on('mousedown', function(e)
{
mousing = true;
multiselectrow($(this));
})
.off('mouseenter')
.on('mouseenter', function(e)
{
mouseenter = e.clientY;
multiselectrow($(this));
})
.off('mouseleave')
.on('mouseleave', function(e)
{
mouseleave = e.clientY;
if(shifting && mousing)
{
tmptrajectory = mouseenter - mouseleave < 0?1:-1;
}
if($(this).hasClass('selected') && shifting && mousing && trajectory != null && trajectory != tmptrajectory)
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
if(shifting && mousing && trajectory == null)
{

}

Thanks to the answer from #JAG I was able to create a nice add on to any HTML table that handles highlighting.
Check out the fiddle for the working version and please use it if you find it helpful or useful for your site.
You can even implement keys to move the tr position up or down in the table. I removed my implementation because it was specific to the project I am working on.
I made it so you have to mouse over the table in order to interact with it and mouse leave to un-focus it.
https://jsfiddle.net/kwj74kg0/2/
//Add the events simply by running this
$('#dtable tr').addEvents(0);
/**
* This add on can be applied and customized to any html tr set i.e. $('#tableid tr').addEvents()
* It will add highlighting capability to the table.
*
* Single click highlight tr
* Click -> Shift + click highlight/toggle range
* Shift+MouseDown+Drag highlight/toggle range
* Ctrl+Click toggle item

how to display "no result found" list search in jquery?

this is work fine..any idea about how to display "no result found"..
Here my code http://jsfiddle.net/UI_Designer/8p426fog/4/
$(".my-textbox").keyup(function() {
var val = $(this).val().toLowerCase()
$(".personsMenu li").each(function(i) {
var content = $(this).html();
if(content.toLowerCase().indexOf(val) == -1) {
$(this).hide()
} else {
$(this).show();
}
});
});
Thank You..
More elegant and the simplest way it to add extra variable and add <div class="no-results" style="display:none">no results found</div> into DOM, and then toggle visibility of the block jsFiddle
var $block = $('.no-results');
$(".my-textbox").keyup(function() {
var val = $(this).val();
var isMatch = false;
$(".personsMenu li").each(function(i) {
var content = $(this).html();
if(content.toLowerCase().indexOf(val) == -1) {
$(this).hide();
} else {
isMatch = true;
$(this).show();
}
});
$block.toggle(!isMatch);
});
Use the below code for no result found.
$(".my-textbox").keyup(function() {
var val = $(this).val();
$(".personsMenu li").each(function(i) {
var content = $(this).html();
if(content.toLowerCase().indexOf(val) == -1) {
$(this).hide();
$(".personsMenu").html("<ul><li><label> NO RESULT FOUND!</label></li></ul>");
}
else {
$(this).show();
}
});
});
Hope this fullfill your requirement.

Javascript Smooth Scrolling - Not working with second click

I use the following script for a smooth scroll effect minus an amount of pixel on one page. The problem is, i click on one anchor link, the scroll effects works as it should but then i scroll back to the top of the page where the links are and click on another page. It doesnt work. I just copied the script from a webpage my javascript is very bad.
Thx for your help.
function filterPath(string) {
return string
.replace(/^\//,'')
.replace(/(index|default).[a-zA-Z]{3,4}$/,'')
.replace(/\/$/,'');
}
var locationPath = filterPath(location.pathname);
var scrollElem = scrollableElement('html', 'body');
$('a[href*=#]').each(function() {
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath
&& (location.hostname == this.hostname || !this.hostname)
&& this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
var targetOffset = $target.offset().top - 70;
$(this).click(function(event) {
if(event != 'undefined') {
event.preventDefault();}
$(scrollElem).animate({scrollTop: targetOffset}, 400, function(e) {
e.preventDefault();
location.hash = target;
});
});
}
}
});
function scrollableElement(els) {
for (var i = 0, argLength = arguments.length; i <argLength; i++) {
var el = arguments[i],
$scrollElement = $(el);
if ($scrollElement.scrollTop()> 0) {
return el;
} else {
$scrollElement.scrollTop(1);
var isScrollable = $scrollElement.scrollTop()> 0;
$scrollElement.scrollTop(0);
if (isScrollable) {
return el;
}
}
}
}
There's an error in the code.
Where it says:
$(scrollElem).animate({scrollTop: targetOffset}, 400, function(e) {
e.preventDefault();
location.hash = target;
});
You are calling preventDefault() on nothing. Leave it as this and it will work:
$(scrollElem).animate({scrollTop: targetOffset}, 400, function() {
location.hash = target;
});
The error was at the beggining of the code. Instead of using an each loop, you should add a clickevent to the anchor elements. By using the each loop, you only add the click event once, and thus on the second click the event is undefined and the code runs into an error.
Here's your code rewritten as a click event:
$('a[href*=#]').click(function(e){
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath && (location.hostname == this.hostname || !this.hostname) && this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
var targetOffset = $target.offset().top - 70;
$(scrollElem).animate({scrollTop: targetOffset}, 400, function() {
if( e != 'undefined' ) {
e.preventDefault();
}
location.hash = target;
});
}
}
});
Hope this helps ;-)
