I am using MaterializeCSS and React to render a simple dropdown based on whether the user is logged in or not.
The idea is that if the user is logged in, to show the dropdown menu and if they are not, to only show a logout link.
<nav className="transparent black-text" role="navigation">
<ul id="dropdown" className="dropdown-content">
<li>My Profile</li>
<li>My Documents</li>
<li className="divider"></li>
<li>
<a href="/#"> Logout
</a>
</li>
</ul>
<div className="nav-wrapper container">
<a className="brand-logo brand-logo-small" href="/">
<img alt="Logo" id="header-logo" src="../../images/favicon.png"/>
{'My Document'}
</a>
<ul className="right hide-on-med-and-down" id="nav-mobile">
<li>
{this.state.loggedIn == 'true'
? <a className="dropdown-button"
data-activates="dropdown"
data-beloworigin="true"
data-constrainwidth="false"
href="/#">{'User'}
<i className="material-icons right">arrow_drop_down</i>
</a>
: Login
}
</li>
</ul>
</div>
</nav>
In the above snippet, if the loggedIn flag equals true, I expect that the dropdown should be displayed, but it isn't.
However, when I add className="dropdown-button" data-activates="dropdown" attributes to the second <a> tag, the dropdown gets displayed.
Additionally, if I remove the className="dropdown-button" data-activates="dropdown" attributes from the first link, the dropdown is still displayed.
What could I be doing wrong here? Why is the dropdown on the first <a> tag only displayed when I set the attributes on the second <a> tag?
Thanks in advance.

I need help setting a link as active upon clicking on my html top nav bar.
The nav bar looks like this
<div class="collapse navbar-collapse pull-left" id="navbar-collapse">
<ul class="nav navbar-nav">
<li>
Home <span class="sr-only">(current)</span>
</li>
<li class="dropdown">
Clients <span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li>Add New Client</li></i></a></li>
</ul>
</li>
</ul>
</div>
So when i click Home it must highlight Home when i click on Clients it must highlight Clients. I really don't know how to achieve this so any help will be very much appreciated.
// when any a link click
$('a').click(function(){
// if already any element in active status remove it
$('a').removeClass('active');
// add active status to this one only
$(this).addClass('active');
})
.active{
background-color:red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="collapse navbar-collapse pull-left" id="navbar-collapse">
<ul class="nav navbar-nav">
<li>
Home <span class="sr-only">(current)</span>
</li>
<li class="dropdown">
Clients <span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li>Add New Client</li></i></a></li>
</ul>
</li>
</ul>
</div>
Setting via JS is pretty pointless, since as soon as it redirects and loads the new page, that setting will be forgotten. What you want to do is have PHP check your current route, and assign a class based on that. This can be done via the request()->is() check:
If navigating to myapp.com/home, use the following:
<li class="{{ request()->is('home') ? 'active': '' }}">
<a href="{{ route('home') }}">
Home
#if(request()->is('home'))
<span class="sr-only">(current)</span>
#endif
</a>
<li>
This demonstrates how to use via a ternary operator (best used for in-line statements) and the #if()#endif blade syntax. Just ensure your is() check is matching your route, so ->is("") for Route::get("/", ...);, etc. etc. and PHP will automatically assign the active class and (current) SR element.
Note; there is likely a way to handle this for named routes (like route('home')), but I haven't used named routes much, so I'm not positive on that. Also, might be best to assign the result of request()->is('home') to a variable to avoid repeating code.
I have a sample login page which directs to a dashboard. The login page is set as the initial redirect page and this routes to the dashboard. The dashboard contains a dropdown menu with some links. Everytime a link is clicked it keeps redirecting to the login page. However, when the dashboard page is reloaded the dropdown menu works completely fine.
I am thinking of using the "event.preventDefault()" for the links but I hope there is a workaround.
Dashboard Menu - HTML
<div class="navbar-default sidebar" role="navigation">
<div class="sidebar-nav navbar-collapse">
<ul class="nav" id="side-menu">
<li>
<i class="fa fa-calendar fa-fw"></i> Manage Events<span class="fa arrow"></span>
<ul class="nav nav-second-level collapse">
<li>
Lorem Ipsum
</li>
<li>
Lorem Ipsum
</li>
</ul>
<!-- /.nav-second-level -->
</li>
</ul>
</div>
<!-- /.sidebar-collapse -->
</div>
Edit: After getting some replies, I would like to clarify my main problem.The problem exists in the link being a null link and that Angular 2 takes it as a null link and causes it to redirect it. If I could find a workaround to tell Angular, don't take this link as a null link it will be ideal.
If you don't want any redirection when clicking on your link(s), check out these solutions:
Different methods to make a null link?
Or you can put <a> tag without href attribute.
<div class="sidebar-nav navbar-collapse">
<ul class="nav" id="side-menu">
<li>
<i class="fa fa-calendar fa-fw"></i> Manage Events<span class="fa arrow"></span>
<ul class="nav nav-second-level collapse">
<li>
<a [routerLink]="['ManageEvents/LoremIpsum']">Lorem Ipsum</a>
</li>
<li>
<a [routerLink]="['ManageEvents/LoremIpsum']>Lorem Ipsum</a>
</li>
</ul>
<!-- /.nav-second-level -->
</li>
</ul>
</div>
export const routes: Routes = [
{ path: 'ManageEvents/LoremIpsum', component: ManageEventsLoremIpsum }
];
This works for me!!
link
hope this helps link also working by this way
For me I used the routerLink and set it to empty:
<a [routerLink]="" (click)="onClickPage()">Click me</a>
try to remove href, setting cursor: pointer with css and handle click on th a element like <a (click)=yourFunction()></a>. it should work ;)
Just simply use <a href>Lorem Ipsum</a>.
I had a situation after parent received events from child component, it redirect to homepage. I solved the problem in parent
receiveMessage($event) { //do something this.router.navigateByUrl('/parent-route'); }
even the parent route are supposed to accept parameters.
For me it javascript:void(0); works. Angular 14
Last Page // HTML file
I am working on designing a page by looking at the image I have. I am stuck on the menu bar design as I am not able to figure out how can I design the menu bar like I have in my image. It should exactly match with what I have in my image.
Here is my jsfiddle and here is my image which I am trying to replicate.
I tried creating horizontal menu bar as shown in that image but somehow my menus are not showing at all. It looks like they are hidden somewhere. Here is my HTML code:
<div class="topnav">
<img src="https://s4.postimg.org/ojd13poal/northman_wordmark_CMYK.png">
<nav>
<ul>
<li class="dropdown">
<b>PROGRAMS</b> <i class="fa fa-angle-down"></i>
<ul class="dropdown-content">
<li><i>INDIVIDUAL</i>
</li>
<li><i>CORPORATE</i>
</li>
</ul>
</li>
<li class="dropdown">
<b>WORLD OF NORTHMAN</b> <i class="fa fa-angle-down"></i>
<ul class="dropdown-content">
<li><i>BE EXTRODINARY</i>
</li>
<li><i>RISK & REWARD</i>
</li>
<li><i>BLOG</i>
</li>
<li><i>OUR STORY</i>
</li>
</ul>
</li>
</ul>
</nav>
</div>
<div class="header"> <img class="header-background" src="https://s3.postimg.org/yr4kr8v0j/kaestle-chris-davenport-antarktis-2009-04.png"> <img class="orange-bar" src="https://s23.postimg.org/od4umnehn/orange-bar.png">
<h1 class="text-inside-orange">INSURANCE FOR THE WILD</h1>
</div>
What is wrong I am doing here? Also I need to make Log in | Sign up using font aswesome (and I have already imported its css in my jsfiddle) and GET COVERED button as well.
The first 2 problems are:
.dropdown {
display: none; /* get rid of this */
}
and you need your img to float: left.
I have a side bar menu collapsible submenu in my Angular project. I used isActive comment for showing active state. When i refresh any page it should show the particular menu with active state. it works on when i refresh submenu's first link. If i click submenu's second link, it doesn't work.
I dont know how to declare active more than a link. ng-class="{show:isActive('/create-workorder')}"
My code is below
<ul>
<li>Work
<ul class="second_level" ng-class="{show:isActive('/create-workorder')}">
<li>
<a href="#/create-workorder" class="" ng-class="{active_sub:isActive('/create-workorder')}">
<div class="create_wo"></div>Create WO</a>
</li>
<li>
<a href="#/workorder-all" class="" ng-class="{active_sub:isActive('/workorder-all')}">
<div class="overall_queue"></div>Overall all</a>
</li>
</ul>
</li>
<li>Status
<ul class="second_level" ng-class="{show:isActive('/history')}">
<li>
<a href="#/history" class="" ng-class="{active_sub:isActive('/history')}">
<div class="status"></div>History</a>
</li>
<li>
<a href="#/recent" class="" ng-class="{active_sub:isActive('/recent')}">
<div class="recent"></div>Recent</a>
</li>
</ul>
</li>
</ul>
A common technique to use to determine active menu is to use the URL itself.
On page refresh you can check the URL and highlight corresponding menu.
For parent-child menu, you can choose to code the relationship, e.g. specify that you should also highlight "status" when you highlight "history".
Or you can use URL itself for the structure, e.g. #/status/history instead of #/history.
I tried to implement a dropdown list that is only visible when the user is signed in. The dropdown list works when outside the "if" statement but not inside. The buttons "Foo" and dropdown button are shown, however it doesn't "dropdown".
header.html
<!-- Header -->
<template name="header">
<nav>
<div class="nav-wrapper">
<a class="brand-logo" href="{{pathFor 'home'}}">Logo</a>
<ul id="nav-mobile" class="right hide-on-med-and-down">
{{#if currentUser}}
<!-- dropdown1 trigger -->
<li>
<a class="dropdown-button" href="#!" data-activates="dropdown1">
<i class="mdi-navigation-more-vert"></i>
</a>
</li>
<li>Foo</li>
{{else}}
<li>Sign in</li>
{{/if}}
<li>About</li>
</ul>
</div>
</nav>
<!-- dropdown1 structure -->
<ul id="dropdown1" class="dropdown-content">
<li class="signout">Sign out</li>
</ul>
</template>
header.js
Template.header.rendered = function () {
$(".dropdown-button").dropdown({
belowOrigin: true // Displays dropdown below the button
});
};
What could be the problem?
When your Template.header.onRendered lifecycle event is first fired, the dropdown HTML elements are not yet inserted into the DOM because the condition {{#if currentUser}} is not yet met (it takes a small amount of time before being actually logged in a Meteor app, that's why Meteor.user being reactive is handy !).
This is why your jQuery dropdown initialization fails : the DOM is not yet ready ! The solution is quite simple thoug : refactor your Spacebars code to put the dropdown markup in its own separate template :
<template name="dropdown">
<li>
<a class="dropdown-button" href="#!" data-activates="dropdown1">
<i class="mdi-navigation-more-vert"></i>
</a>
</li>
<li>Foo</li>
</template>
Then insert the child template inside your header template :
{{#if currentUser}}
{{> dropdown}}
{{else}}
{{! ... }}
{{/if}}
This way the dropdown will have its own onRendered lifecycle event that will get triggered only after the user is logged in, and at this time the dropdown DOM will be ready.
Template.dropdown.onRendered(function(){
this.$(".dropdown-button").dropdown({
belowOrigin: true // Displays dropdown below the button
});
});
Sometimes refactoring your code into smaller subtasks is not just a matter of style, but it makes things work the way intended.
