Page is getting reloaded automatically on click event. Cannot determine why? - javascript

Have got an button in nav, which on click event is supposed to display:block an ul which is initially set to display:none
HTML -
<i class="mdi-navigation-menu small right" id="lines3"></i>
</nav>
<ul class="collection center" id="drop-navv" style="display:none">
<li class="collection-item">Alvin</li>
<li class="collection-item">Alvin</li>
<li class="collection-item">Alvin</li>
<li class="collection-item">Alvin</li>
</ul>
Js -
$(document).ready(function() {
$('#lines3').on('click', function() {
$("#drop-navv").css("display", "block");
});
// other click event
});
But as soon as I click button it works, but immediately page get reloaded! Its been hours but still cannot figure out why its happening!! PS: Am using materialize framework. And other click event as mentioned in comment is working.

You're going to need to prevent the default on your click handler.
So, first I'd change the href to be href='#' and then add this.
$('#lines3').on('click', function(e) {
e.preventDefault();
//your other code here
});
This will prevent the link from going anywhere when someone clicks it.

close menu toggle after click link

I'm having one problem is:
I've one javascript running on all pages and I want to keep it active even if you change pages inside of the website (not refresh) but the problem is that I've one menu toggle and every time that I changed the page, the script starts again. so I changed my code menu and added an attribute to link rel="history".
After doing that, the script works without interrupts, but every time I click on the menu link, the menu toggle doesn't close... remains open when I change the page. and cannot know why. anyone can help me? Thanks in advance.
<a class="toggle-menu">
<i></i>
<i></i>
<i></i>
</a>
<div class="menu-drawer">
<ul>
<li>main</li>
<li>Press</li>
<li>Contacts</li>
</ul>
</div>
$(function() {
$(".toggle-menu").click(function() {
$(this).toggleClass("active");
$('.menu-drawer').toggleClass("open");
});
});

Bootstrap - How to keep drop-down menu open when sub-menu is open

I am having difficulty trying to keep my drop-down menu open when i click on a sub menu. You would think that Bootstrap would do this right out the box. But i cant find any documentation on it.
here is what i found as a solution:
https://www.bootply.com/rgvY6oPO1J
In my HTML i have this:
<div class="btn-group" id="myDropdown">
<a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
Menu
<span class="caret"></span>
</a>
<ul class="dropdown-menu">
<li>Choice1</li>
<li>Choice2</li>
<li>Numbers
<ul class="nav collapse" id="mynumbers" role="menu" aria-labelledby="btn-mynumbers">
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>
</li>
<li>Choice3</li>
<li class="divider"></li>
<li>Choice..</li>
</ul>
</div>
And here is whats in my JavaScript:
$("#btn-mynumbers").on("click", function (e) {
e.stopPropagation();
$("#mynumbers").slideToggle("fast");
});
for the most part it works. But I'm going to have a lot of menu items and i don't want to make a on click caller for every sub-menu i create.
So i tried putting
onclick="Toggle(this);"
in
id="btn-mynumbers"
and creating the function:
function Toggle(element) {
event.stopPropagation();
var parentid = element.id;
var childid = $(parentid).children("ul").attr("id");
$(childid).slideToggle("fast");
}
so i can give every sub-menu click the ability to stay open. but the event stopped ALL propagation, even the slideToggle. I don't know how to keep the drop down open when a sub-menu slides down.
It seems like there was an error with the function you made since event would probably be undefined. I changed it to something like below. But you can see it in action with the codepen link below.
$(".submenu").on("click", function (event) {
event.stopPropagation();
var target = event.currentTarget;
$(target).siblings('ul').slideToggle("fast");
});
The best approach if you don't want to put an id for every possible menu item that has a sub-menu, then work with classes. That way you don't need to recode.
I made you a codepen that shows how to use classes instead of ids as identifiers. I added a sample of another menu item with a sub-menu for you to play around with.
Hope that helps!

How can I close the sidebar menu? (Bootstrap)

I have a side-menu on my bootstrap webpage which is open by default.
If the screen is too small there is a button placed behind it to open the menu again.
When a user clicks on a link I would like the menu to close automatically.
The button I already have opens the menu perfectly, but I have no way of closing it?
<div id="wrapper">
<div id="sidebar-wrapper">
<ul class="sidebar-nav">
<li class="sidebar-brand"><img src="/content/img/AAA.png" width="27px" />Menu</li>
<li data-ng-hide="!authentication.isAuth">Welcome {{authentication.userName}}</li>
<li data-ng-hide="!authentication.isAuth">Page1</li>
<li data-ng-hide="!authentication.isAuth">Logout</li>
<li data-ng-hide="authentication.isAuth"><span class="glyphicon glyphicon-user"></span> Login</li>
<li data-ng-hide="authentication.isAuth"><span class="glyphicon glyphicon-log-in"></span> Sign Up</li>
</ul>
</div>
</div>
<a href="#menu-toggle" class="btn btn-default" id="menu-toggle">
Menu
</a>
<script>
$("#menu-toggle").click(function (e) {
e.preventDefault();
$("#wrapper").toggleClass("toggled");
});
</script>
You could add in another event handler for the a elements.
$(".sidebar-nav li a").click(function() {
$("#wrapper").removeClass("toggled");
});
Here are a few things that you could do:
You could use hide/show with jQuery(I can see you are already using it).
Instead of makeing a "toggled" class, Bootstrap has a built in "hidden" class that you could use.
You could also toggle it's css "display" value.
You could use the "animate" class to slide the menu on and off the screen.
You could have a variable to store the state of the menu("true" for out, "false" for in), and change it when the toggle button is clicked.
I had a similar issue, and I placed a close button on the menu, and added a seperate click handler that would close the menu. The close button would then hide with the menu, leaving just the button to open the menu again.

Jquery Dynatree plugin using clicks in id

Using Firebug I have found that the Dynatree plugin changes the following code:
<li id="id3.1" class="expanded">Menu 1
<ul>
<li id="id3.1.1">Sub-menu 1</li>
</ul>
</li>
To this:
<li class="">
<span class="dynatree-node dynatree-exp-c dynatree-ico-c">
<span class="dynatree-connector"></span>
<span class="dynatree-icon"></span>
<a class="dynatree-title" href="#">Sub-menu 1</a>
</span>
</li>
So when I try to make a click event on the id="id3.1.1" nothing happens because this id doesn't exist anymore.
I made a search here and found the onActivate option that will make my click happen on the menu:
$("#treeMenu").dynatree({
onActivate: function(node){
var menuTitle = node.data.title;
alert(menuTitle);
}
});
My question: Is this the only way to do the click event using Dynatree?
Well I think that is the best option, because it uses the API of the plugin, but of course you could still attach an event to the <a> like this:
$('a.dynatree-title').live('click', function(e){
//here e.target is the link you have clicked
});

jQuery .click event not registering with class

I'm trying to register a click event for a menu list button identified by a class, but it doesn't seem to be firing. My code is as follows:
<body>
<!-- jQuery Simple Drop-Down Menu http://javascript-array.com/scripts/jquery_simple_drop_down_menu/# -->
<div id="dropDownDiv" style="width: 908px; height: 24px; margin: auto auto; background: #324143;">
<ul id="jsddm">
<li>Item 1
<ul>
<li><a class="btn myOtherClass" href="#">Button 1</a></li>
<li><a class="btn myOtherClass"href="#">Button 2</a></li>
</ul>
</li>
<li>Item 2
<ul>
<li><a class="btn myOtherClass" href="#">Button 3</a></li>
<li><a class="btn myOtherClass" href="#">Button 4</a></li>
</ul>
</li>
</ul>
</div>
</body>
And in my script I have the following:
/* Register the click event for menu buttons */
$('.btn').click(function () {
alert("You clicked a button");
});
The alert never fires and I'm not sure why, any help is appreciated.
UPDATE:
The code in the link works for me to, not sure why it's not working in my project. I'm in an Eclipse PHP Project environment with Java resources enabled. I tried my project in Chrome and Firefox, not working for either. I'll check the rest of my script.
UPDATE 2:
Looks like Shef's recommendation about wrapping in a .ready function did the trick. I still don't understand why it needs that to work, "c=smiles"'s link worked without it.
Works fine for me, check it out. Maybe you didn't include jQuery? Or, you are not wrapping your event listener bind code inside a document ready like this:
$(document).ready(function(){
$('.btn').click(function () {
alert("You clicked a button");
});
});
are you using stopPropagation or return false in another click event that may have prevented the click event from happening?
Is the jQuery used after jQuery has been loaded?
Is the in the DOM at the time of binding? (use delegate instead of click if not, or bind after loading)
