jQuery - hide input if maxTags reached using tags.js

Using the tags() function, there is a parameter for maximum number of tags (maxTags) you can enter into each input.
I need to hide(); the tags-input when maxTags = 2 and then
show(); when the tag is removed / not at the max.
maxTags :1 isn't working but it should be. Only 2 or more is acceptable. I tried debugging the max tags parameter but couldn't find out why maxTags: 1 is
unacceptable.
How can I change the function to allow maxTags: 1 and also show/hide the tag-input when maxTags is reached?
// max tags in tags() function:
if (opts.maxTags) {
if ($self.val().split(",").length == opts.maxTags) {
otherCheck = false;
$input.val("");
$next.val("");
}
}
// Calling the tags() function:
$("#" + formId)
.find(".input--proj")
.tags({
unique: true,
maxTags: 2
})
.autofill({
data: autolist
});
(function($) {
$.fn.tags = function(opts) {
var selector = this.selector;
//console.log("selector",selector);
// updates the original input
function update($original) {
var all = [];
var list = $original.closest(".tags-wrapper").find("li.tag span").each(function() {
all.push($(this).text());

$original.val(all);

I've added code to test maxTags value from 1 to 3. Just replace it.
Removed a tag. Show input.
$wrapper.on("click", "li.tag a", function(e) {
e.preventDefault();
$(this).closest("li").remove();
$self.trigger("tagRemove", $(this).closest("li").find("span").text());
update($self);
$("[data-search]").keyup();
$input.show(); // show input on remove
});
If string has no content, return 0. Else use split to find number of elements.
if (opts.maxTags) {
var len = $self.val();
len = len.trim().length > 0 ? len.split(',').length : 0;

CSS/HTML/JS Line up divs with dropdown search preview

UPDATE WITH SOLUTION:
I moved the unordered list to go after the go button,
<div class="row">
<form class="navbar-form suggest-holder">
<input class="form-control input-lg suggest-prompt" type="text" placeholder="Search...">
<select class="form-control input-lg">
<option>All</option>
<option>one</option>
<option>two</option>
<option>three</option>
<option>four</option>
<option>five</option>
<button type="submit" class="btn btn-primary btn-lg">Go</button>
<ul></ul>
</form>
</div>
and added the following to my CSS:
.form-control {
float: left;
}
I have a search bar in my header that is using a JS function for autocomplete based on a small list of sample products.
My site has several categories that can be searched, similar to Amazon, so to the right of the search input box, there is a drop-down menu and a "go" button.
Before I added the autocomplete JS, these were horizontally aligned. Now, the category drop-down and the go button are being pushed below the search input box.
How can I get them horizontally aligned again? I have included a fiddle with the HTML/CSS

Try putting display: inline-block on all of the elements. E.g. form > * { display: inline-block;}. JSfiddle
You could also use float: left to not have the additional margins JSfiddle.
UPDATE:
Use:
.form-control {
float: left;
}
JSfiddle

There is a unordered list just before the select box which is causing the problem. It's defined as display:block and forcing the select box and the button to the next line.

You need another wrapper for the input and ul element which shows the results. Then you need elements with display-inline.
Here your jsfiddle: https://jsfiddle.net/sox0sxmz/8/
<div id-"my-container">
<input class="form-control input-lg suggest-prompt" type="text" placeholder="Search...">
<ul></ul>
</div>
Then apply a float:left to the container.
CSS:
form > * {
display: inline-block;
}
#my-container{
float: left;
}

Allow user to drop item in two different droppable areas inside loop

So I do have a loop of droppable areas where user is able to drop items. Size of the loop can be different. It depends on user's input. You can check fiddle here
Here is my droppable area:
$(".projLeader ol").droppable({
tolerance: 'pointer',
hoverClass: 'highlight',
drop: function(ev, ui)
{
var zz = ui.draggable.text()
var xyz = itm.includes(zz);
if (xyz === false)
{
var item = ui.draggable;
if (!ui.draggable.closest('.placeholder').length) item = item.clone().draggable();// if item was dragged from the source list - clone it
//this.innerHTML = ''; // clean the placeholder
item.addClass('dropClass').appendTo(this);
// append item to placeholder
//add to array
itm.push(zz);
var n = $(this).closest("div.proc").find(".dropClass").length;
$(this).closest("div.proc").find("h6").text("Items Dropped: " + n + ".");
}
else
{
alert('Name is Already Exist');
}
}
});
The problem is I got warning message for each field. For example if I drop item in box1 and then want to drop same item in box2 I got warning message. How can I fix it? Thanks for any help

I spent some time understanding your code and here's the solution. I added some code to detect if an existing box already exists.Hope it helps :)!
var itm = [];
$( "#savebutton" ).click(function() { LISTOBJ.saveList(); });
$("#myAccordion").accordion({heightStyle:"content", active: false, collapsible:true});
$("#myAccordion li").draggable({
appendTo: "body",
helper: "clone",
start: function(ev, ui){ ui.helper.width($(this).width()); }
});
$(".projLeader ol").droppable({
tolerance: 'pointer',
hoverClass: 'highlight',
drop: function(ev, ui)
{
var zz = ui.draggable.text()
var xyz = itm.includes(zz);
if (xyz === false)
{
var item = ui.draggable;
var map = {}, i , size;
var flag = false;
if (!ui.draggable.closest('.placeholder').length){
item = item.clone().draggable();// if item was dragged from the source list - clone it
//this.innerHTML = ''; // clean the placeholder
item.addClass('dropClass').appendTo(this);
// append item to placeholder
//add to array
var n = $(this).closest("div.proc").find(".dropClass").length;
$(this).closest("div.proc").find("h6").text("Items Dropped: " + n + ".");
var listOfElements = $(this).closest("div.proc").find("li").text();
var newarr = listOfElements.split('x');
newarr.shift();
var actualArrayLength = newarr.length;
for (i = 0, size = newarr.length; i < size; i++){
if (map[newarr[i]]){
xyz = true;
alert("Name is Already Exist");
$(this).closest("div.proc").find("h6").text("Items Dropped: " + (n - 1) + ".");
$(this).closest("div.proc").find("li:last-child").remove();
return false;
}
else{
map[newarr[i]] = true;
newarr[newarr.length - 1];
}
}
}
}
}
});
$(".projLeader").on('click', '.closer', function(){
var item = $(this).closest('.item');
itm.splice(item);
item.fadeTo(200, 0, function(){ item.remove(); })
});
var LISTOBJ = {
saveList: function() {
var listCSV = "";
$( ".projLeader li" ).each(function() {
if (listCSV === "") {
listCSV = $(this).text();
} else {
listCSV += ", " + $(this).text();
}
$("#output").text(listCSV);
$(".hiddenListInput").val(listCSV);
});

How to avoid first Character value is “-“from the Word entered in the Input box

I need to avoid only first character value is - symbol in text box.
$(document).on("keypress", "#form_name", function() {
if ($('#form_name').val().substr(0, 1) == "-") {
return true
} else {
return false
}
});
I am trying this method it is not working properly.
Kindly guide me to resolve the issue.

You need to swap what you have given:
$(document).on("keyup", "#form_name", function() {
if ($('#form_name').val().substr(0, 1) == "-") {
$('#form_name').val("");
return false;
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input id="form_name" />
I have also added a small error message with this. Check it out:
$(".error").hide();
$(document).on("keyup", "#form_name", function() {
if ($('#form_name').val().substr(0, 1) == "-") {
$('#form_name').val("");
$(this).next(".error").fadeIn();
return false;
} else
$(this).next(".error").fadeOut();
});
.error {display: inline-block; vertical-align: middle; padding: 2px; border: 1px solid #f00; background: #f66; color: #fff; font-weight: bold; font-size: 0.8em; border-radius: 3px;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input id="form_name" />
<span class="error">Cannot start with -.</span>

$(document).on("keyup", "#form_name", function() { //when a user types in input box
var formValue = this.value;
if ( formValue.charAt( 0 ) == '-' ) {
return false;
} else {
return true;
}
});

Event Handlers On Newly Created Elements

I have a web app with a number of textareas and the ability to add more if you wish.
When you shift focus from one textarea to another, the one in focus animates to a larger size, and the rest shrink down.
When the page loads it handles the animation perfectly for the initial four boxes in the html file, but when you click on the button to add more textareas the animation fails to accomodate these new elements... that is, unless you place the initial queries in a function, and call that function from the addelement function tied to the button.
But!, when you do this it queries as many times as you add a new element. So, if you quickly add, say 10, new textareas, the next time you lay focus on any textarea the query runs 10 times.
Is the issue in my design, or jQueries implementation? If the former, how better can I design it, if it is the latter, how can I work around it?
I've tried to chop the code down to the relevant bits... I've tried everything from focus and blur, to keypresses, the latest is on click.

You should use the following:
// New way (jQuery 1.7+) - .on(events, selector, handler)
$(document).on("click", "textarea", function () {
event.preventDefault();
alert('testlink');
});
Since the textarea is added dynamically, you need to use event delegation to register the event handler.

Try
$(document).on('click', 'textarea', function() {
// do something
});

The issue is you are binding the textareas only on the page load. I made a JSFiddle with working code: http://jsfiddle.net/VpABC/
Here's what I changed:
I wrapped:
$('textarea').on("click", function () {
//alert(this.id.substring(0,3));
if (this.id.substring(0, 3) == 'box') {
$('textarea').animate({
height: "51"
}, 1000);
$(this).animate({
height: "409"
}, 1000);
} else {
$('textarea').animate({
height: "51"
}, 1000);
}
});
in a function so it looked like this:
function bindTextAreas() {
$('textarea').unbind("click");
$('textarea').on("click", function () {
//alert(this.id.substring(0,3));
if (this.id.substring(0, 3) == 'box') {
$('textarea').animate({
height: "51"
}, 1000);
$(this).animate({
height: "409"
}, 1000);
} else {
$('textarea').animate({
height: "51"
}, 1000);
}
});
}
bindTextAreas();
What this does is it allows you to call this function, bindTextAreas, whenever you create a new textarea. This will unbind all the current events than rebind them. This will make it so your new textarea is has the click handler setup.
An place where this function is called is in the addele function like this:
function addele() {
var tops = document.getElementById('top');
var num = numb + 1;
var romu = romanise(num);
var newbox = document.createElement('textarea');
var newboxid = 'box' + num;
newbox.setAttribute('id', newboxid);
newbox.setAttribute('class', 'tecksd');
newbox.setAttribute('placeholder', '(' + romu + ')');
tops.appendChild(newbox);
numb = num;
onit();
bindTextAreas();
} //addele(), add element
Notice the bindTextAreas(); line near the bottom. This reloads all the click handlers.
