Sidebar menu treeview not working after redirection in Angular 4

mb00110101 commented 7 years ago

Hi,

I'm using AdminLTE theme (2.4.0-rc) in Angular4 project. Dashboard with the sidebar menu is on url "http://host/". When I enter this address in browser address field, everything is working correct. Problem is when app is on other url, i.e. "http://host/login" and there is link to main page or redirection in code used one of methods: this.router.navigateByUrl('/') or <a routerLink="/">. After redirection to the Dashboard by one of these methods, sidebar menu "treeview" option does not open. Therefore after redirection by <a href="/"> everything works correct. There isn't any errors in dev console. It seems like some AdminLTE js function not see "treeview" element after redirection by Angular 4 methods. Is it any solution to make Angular 4 works as expected?

Hi i have same problem in using vue2. Refreshing page fixes this but this its not a solution.

XpamAmAdEuS commented 7 years ago

I replaced $(window).on('load', function () with $( document ).ready(function() in // Tree Data API and now all good.

// $(window).on('load', function () { // $(Selector.data).each(function () { // Plugin.call($(this)) // }) // }) $( document ).ready(function() { $(Selector.data).each(function () { Plugin.call($(this)) }) });

Hello @mb00110101, i had the same problem in a Angular 4 application.

In my case, i have the loginPage and the homePage

When i reload the homePage, everything is ok. But, if i navigate from loginPage to "homePage" the treeview menu was not working.

In my analysis i see that adminlte.js file initializes treeview plugin in the document.load function, but, in this momment, the DOM will not have the treeview elements. So, in the homePage ngOnInit method i put a code to initialize the treeview.

ngOnInit() {
    $(document).ready(() => {
      const trees: any = $('[data-widget="tree"]');
      trees.tree();
    });
  }

and, of course my treeview in HTML has the attribute data-widget=tree like the following

<ul class="sidebar-menu" data-widget="tree">
  <li class="header">Menu</li>
  <li class="treeview link-pointer" routerLinkActive="active menu-open">
      <a>
        <i class="fa fa-linux"></i> <span>Item</span>
         <span class="pull-right-container">
            <i class="fa fa-angle-left pull-right"></i>
         </span>
       </a>
      <ul class="treeview-menu">
            <li class="" routerLinkActive="active"><a [routerLink]="['/main']"><i class="fa fa-linux"></i> Sub Item</a></li>
      </ul>
   </li>        
</ul>

I hope it can help you. Bye

Hi, the solution by @mateusduraes did not work. Error: tree is not a function

mateusduraes commented 7 years ago

Hello @thiagoreis, your HTML and TSC looks like mine? Do you have the [data-widget="tree"] in HTML of the component? And. please make sure of call this code below

ngOnInit() {
    $(document).ready(() => {
      const trees: any = $('[data-widget="tree"]');
      trees.tree();
    });
  }

in the component that has the HTML properties. If you can share the code, i can try to help you.

What version of AdminLTE you're using? You can see my solution working in this project if you want

thiagoreis commented 7 years ago

Thanks @mateusduraes! when check you project i found my problem. I was import the files adminlte.js and AdminLTE.css in my index.html file. changing the import for angular-cli.json work fine:

"styles": [
    "styles.css",
    "../node_modules/admin-lte/dist/css/AdminLTE.css",
    "../node_modules/admin-lte/dist/css/skins/_all-skins.css"
],
"scripts": [
    "../node_modules/admin-lte/dist/js/adminlte.js"
],

Thank you! Your solution works and the sidebar turns normal.

viniciuslj commented 6 years ago

This problem in Angular 6 and AdminLTE 3 was solved as follows:

Note: I have a Sidebar component that contains the treeview.

Import jquery and AdminLTE

import * as $ from 'jquery';
import * as AdminLte from 'admin-lte';

...

In ngAfterViewInit:

ngAfterViewInit() {
    $('[data-widget="treeview"]').each(function() {
        AdminLte.Treeview._jQueryInterface.call($(this), 'init');
    });
}

I do not know if this is the best solution, but it worked.

lterfloth commented 6 years ago

I tried @mateusduraes solution but I can't seem to get it to work. It always tells me that trees() is not a function. I included all the styles and scripts as @thiagoreis suggested.

When trying @viniciuslj suggestion I get the error that _jQueryInterface can't be found.

Any idea?

lterfloth commented 6 years ago

I got it working. You have to make sure to install and import jquery-ui-dist. "scripts": [ "../node_modules/jquery-ui-dist/jquery-ui.js" ],

iyilm4z commented 5 years ago

Hi @mateusduraes , thanks for sharing your source code with us. It worked for me. But now i have another problem that maybe you can help me with. I try to implement dynamically generated tree menu. I'm about to finish it but i have an annoying problem which took my hours.

Tree menu nodes which have childs keep opened when they should be closed/collapsed after i click another nodes in the tree menu. There is also an open issue here but i'm not sure if my code is correct. I also tried it on your code but it produces the same unwanted result. Have you ever tried to create three/multi level menu?

Here are screenshots. Yours. err1

Mine. err2

how to do it in admin lte 3

You got it?

dnzbrkyrk commented 4 years ago

Hello,

I faced the same problem on AdminLTE 3 with React. This is how I solved it.

Create a JavaScript file with the content below :

const $ = window.$; export function loadTree() {


  const trees: any = $('[data-widget="treeview"]');
         trees.Treeview('init');

}

And on the react component which contains the menu items invoke this function inside componentDidMount()

import { loadTree } from "./js/MenuTreeHelper.js";


export default class Menu extends Component {

componentDidMount() { loadTree(); }

Thank you dnzbrkyrk it's work correctly

mh7777777 commented 4 years ago

For anyone who is struggling with this. I'm using AdminLTE 3.0 with React. Same situation, redirecting user from Login to Dashboard.

useEffect(() => { const trees = window.$('[data-widget="treeview"]'); trees.Treeview('init'); }, []);

or you can set in componentDidMount() if you are using class-based component. Spend 2 days investigating this.

Hope it helps.

oscarlofwenhamn commented 4 years ago

@mh7777777 At what level are you adding this effect? I've been struggling with this for some time but I keep getting TypeError: window.$ is not a function no matter what level I add it, it seems. My project is heavily based on the erdkse/adminlte-3-react repo, could it be a version problem? With that said, I am very new at working with React, so I may very well be missing something obvious.

Make sure you add it on top level component where your children or JSX from that component contain Sidebar menu and all of these features from Dashboard. useEffect will be called after everything is rendered. With that said, that's the right moment when this snippet of code needs to run because everything is in DOM right now.

TypeError: window.$ is not a function is simple. You are missing jQuery in project. Make sure you insert it since AdminLTE is using it.

oscarlofwenhamn commented 4 years ago

Edit: I missed it before, but now saw the import * as $ from 'jquery'; line above, I will give it a try.

Thanks for the explanation, it is much appreciated. I seem to be stuck on what I'm guessing is another low level issue - I still can't get the window.$ right. I've added jquery via npm install jquery --save, and tried import $ from 'jquery;, but it doesn't connect $ to window.$. I found an SO-page where the following snippet could be found, do I need to "initialize" it in this way, in lack of a better word, or am i way off?

import $ from 'jquery';
window.jQuery = $;
window.$ = $;
global.jQuery = $;

oscarlofwenhamn commented 4 years ago

I suspect something is off with my project; I either keep getting TypeError: window.$ is not a function or (when trying it with just $ instead of window.$): TypeError: trees.Treeview is not a function.

Are jQuery and admin-lte required to be devDependencies or regular dependencies?

Any tips on how you correctly insert jQuery would be greatly appreciated, and if you have a guess as to why the Treeview function isn't present (though I understand that might be a tough guess without knowing the project).

Thank you brother, it worked here for me. I'm using angular 8.0.3 and admin lte 3.0.5

danielsa97 commented 4 years ago

I believe it is a problem of the circle of life, as @mateusduraes said.

The solution proposed by @viniciuslj worked fine with me, in my case i are using vuejs. i imported the AdminLte in script's area how to global window.AdminLte = require('admin-lte'); in mounted() i cloned the code

mounted() { $('[data-widget="treeview"]').each(() => { AdminLte.Treeview._jQueryInterface.call($(this), 'init'); }); }

Sorry for the mistakes in my english, I'm learning.

this really worked for me thanks a lot. one other thing make sure you call useEffect in the component which has the navbar HTML or has the data-widget otherwise calling it in another component wont work unless the component with the widget is in the rendered component tree.

It worked for me but now the topbar toggle button to hide the sidebar is not working, any idea?

Hello, to those who cannot close the treeview is due to it is init more than once. One possible solution

import * as $ from 'jquery';

export function loadTreeview() {
    $('[data-widget="treeview"]').each(function () {
        if ($(this).data('treeview-init') === undefined) {
            $(this).Treeview('init');
            $(this).data('treeview-init', true);

MikhaelMounay commented 5 months ago

I'm facing the same issue. I working on a web application with AdminLTE 3 and React.js 18 on Vite 5. The sidebar works fine without adding any code on Google Chrome and Brave. However, this error persists on Microsoft Edge (Chromium based) where the buttons of the tree view are not working.

If I use this snippet,

export function loadTreeview() {
    $('[data-widget="treeview"]').each(function () {
        if ($(this).data('treeview-init') === undefined) {
            $(this).Treeview('init');
            $(this).data('treeview-init', true);
        }
    });
}

MS Edge works fine, but Google Chrome & Brave don't work as expected where the menus expand only but don't collapse.

Anyone has an idea ?!
