Vue router
const router = new VueRouter({
routes: [
{ path: '/home', component: load('home') },
{ path: '/insert', component: load('insert') },
{ path: '/update/:id', component: load('update') },
{ path: '/feedback', component: load('feedback') },
{ path: '*', redirect: '/home' }
]
});
File name and type: _home.html, _insert.html, _update.html, _feedback.html
Can help me see the problem, thank you
I don't think you should edit directly to index.html as Vue is Single Page Application (SPA) framework. Instead, you should use Vue Component for each page.
This video might help you to figure out how to use Vue and Vue Router properly: https://youtu.be/nnVVOe7qdeQ
Edit:
For sake of clarity, Let me build simplified diagram of Vue project for you.
First of all, make sure you create the project via vue cli. It guides you to build your new vue project better.
Let's say we have 3 pages:
Home
About
Another
Each page has its own CSS, HTML (we call it template), and JavaScript in one file, the .vue file. To connect them, we need a first entrance, main.js. Inside of it, we can configure the router.
Inside main.js
import Vue from "vue";
import VueRouter from "vue-router";
import App from "./App.vue";
import HomePage from "./HomePage.vue";
import AboutPage from "./AboutPage.vue";
import AnotherPage from "./AnotherPage.vue";
// This is your router configuration
Vue.use(VueRouter);
const router = new VueRouter({
[
{ path: "/", component: HomePage },
{ path: "/about", component: AboutPage },
{ path: "/another", component: AnotherPage },
],
mode: "history",
});
// Initialize Vue App
new Vue({
router,
render: h => h(App),
}).$mount("#app");
Then, we need to create App.vue and put <router-view /> inside of it.
Inside App.vue source file
<template>
<div id="app">
<router-view />
</div>
</template>
<script>
export default {
// Keep this empty. Except if you
// need to add sidebar or any else.
}
</script>
Now you're ready to create those three pages
Every pages looks like this:
<style scoped>
// Your CSS here
</style>
<template>
<div>
<!-- Your HTML here -->
</div>
</template>
<script>
export default {
data() {
return {
// Your reactive data here
}
},
mounted() {
// Your script here
},
methods: {
// Your functions here
},
}
</script>
That's all I can explain, hope it helps. If I missed something, please don't hesitate to tell me. Thank you!
I want to do a common thing - include dynamically an svg HTML in Vue Nuxt application which I will able to style. To do this, I created a component but instead of image, I get a text data:image/svg+xhtml....
How to make it work?
<template>
<div v-html="src"></div>
</template>
<script>
export default {
name: 'Icon',
props: {
name: {
type: String,
required: true
}
},
computed: {
src() {
const src = require(`assets/icons/${this.name}.svg`)
return src
}
}
}
</script>
It seems like #nuxtjs/svg will do what you're trying to do. After installing it, try:
<template>
<div v-html="src"></div>
</template>
<script>
export default {
name: 'Icon',
props: {
name: {
type: String,
required: true
}
},
computed: {
src() {
const src = require(`assets/icons/${this.name}.svg?raw`)
return src
}
}
}
</script>
It's not easy and I tried a bunch of different solutions that "seemed" like they should work.
My understanding is that it comes down to how Webpack deals with "image" assets and using them inline vs stand-alone sort of changes the definition.
I've got a library of SVG icons that needed code access (eg change colors after run time) so I had to have the SVG inline. Here's where I landed, It's not ideal but it works.
Create a new component with a prop slot for SVG name. Inside that component add all your svg's as code. Wrap each in a v-if.
<template>
<div class="svgIcon">
<svg v-if="icon == 'name1'">...</svg>
<svg v-if="icon == 'name2'">...</svg>
<svg v-if="icon == 'name3'">...</svg>
<svg v-if="icon == 'name4'">...</svg>
</div>
</template>
<script>
export default {
props: ['icon']
}
</script>
Then use the component by filling the name you want in the slot
<template>
<div>
<svgIcons :icon="name1"></svgIcons>
</div>
</template>
<script>
import svgIcons from '../path/to/iconsComponent.vue'
export default {
components: { svgIcons },
...
}
</script>
vue-router works well, but <router-link to="/path">Link</router-link> element isn't rendering to Link but just to plain text Link. Let me show you my code:
index.html
<div id="wrapper">
<!-- Content -->
<router-view></router-view>
</div>
app.js
const Vue = require('vue');
import VueRouter from 'vue-router';
Vue.use(VueRouter);
//routing stuff
import GMap from './components/g-map.vue';
import Home from './components/home.vue';
const router = new VueRouter({
routes: [
{ path: '/', component: Home },
{ path: '/g-map', component: GMap }
]
});
new Vue({
router
}).$mount('#wrapper');
home.vue
<template id="home">
<div>
<!-- some stuff -->
<router-link to="/g-map">Link</router-link>
Another link
</div>
</template>
<script>
export default {
methods: {
testVueRoute() {
this.$router.push({ path: "g-map" });
}
}
};
g-map.vue
<template id="g-map">
<div>SOME CONTENT FROM G-MAP</div>
</template>
<script>
export default {};
</script>
home component is rendered at start (because has a path / in routing) and on the loaded site I can see text "Link" and clickable link "Another link". Source of the site looks like this:
<div>
<!-- some stuff -->
Link
Another link
</div>
Clicking on the text "Link" does nothing, cliking on the "Another link" call successfull testVueRoute method and content of g-map component appear.
Vue-route do a job because this.$router.push({ path: "g-map" }); works well, but why the <router-link to="/path">Link</router-link> element is not rendering to a tag?
According to this topic the solution is updating vue and vue-router package to newest version (probably you have to update vue-template-compiler too).
Include the tag attribute within your router link - like so: <router-link tag="a" to="/g-map">Link</router-link>
Try like this. <router-link :to="{ name: 'your name here' }" class="btn btn-primary">Create Catgeory</router-link>
And in app js add name like this.
{
name: 'home',
path: '/',
component: HomeComponent
}
I am trying to use multiple UI-views in my AngularJS app and it is not working as expected. The app is a dashboard.
My directory structure is as follows:
index.html
app/
app.js
dashboard/
dashboard.html
dashboard.js
partials/
business.html
items.html
orders.html
sales.html
login/
login.html
login.js
The problem that I am having is that my index.html file has the following line of code:
<div ui-view></div>
The above line enables my application to show the login.html page and dashboard.html page. Now I want to be able to have partial views in my dashboard.html page and so I have also put the same line of code
<div ui-view></div>
in order to be able to embed partial views in my dashboard page. Instead of embedding though, the page instead just redirects. So for example if I am in my dashboard.html and click on a navigation item such as 'business', I am redirected to partials/business.html instead of the content being embedded.
1) Can I have multiple ui-views embedded within each other?
2) Am I correctly embedding the partial views?
I have scoured the internet but cannot find a solution. Thanks in advance for the help!
You can definitely have multiple embedded views.
Check out these AngularJS UI-Router tutorials: Nested Views and Multiple Named Views.
Let me know if you still have issues after looking them over.
You can define a ui-view inside another ui-view. I have implemented it in the following manner and its pretty straight forward.
Inside index.html I have code:
<div ui-view=""></div>
Then inside user.html I have code
<div ui-view=""></div>
And I have defined a config for displaying my views as
.config(function($urlRouterProvider, $stateProvider) {
var users = {
//Name must be in format Parent.Child
name: 'users',
url: '/user',
templateUrl: 'users/user.html',
controller: 'usersHandler',
data: {
pageTitle: 'Welcome to Users'
},
},
createUsers = {
name: 'users.createUsers',
url: '/createUser',
templateUrl: 'users/createUser.html',
data: {
pageTitle: 'Create Users'
}
},
listUsers = {
name: 'users.listUsers',
url: '/listUsers',
templateUrl: 'users/userLists.html',
data: {
pageTitle: 'Users listing'
}
},
getUserDealer = {
name: 'users.getUserDealer',
url: '/getUserDealer',
templateUrl: 'users/getUserDealer.html',
data: {
pageTitle: 'Users dealer listing'
}
},
editUser = {
name: 'users.editUser',
url: '/editUser',
templateUrl: 'users/editUser.html',
data: {
pageTitle: 'Edit User'
}
};
//Similarly define all the combination you want to separate
//add routes to stateProvider
$stateProvider
.state('users', users)
.state('users.createUsers', createUsers)
.state('users.listUsers', listUsers)
.state('users.getUserDealer', getUserDealer)
.state('users.editUser', editUser);
$urlRouterProvider.otherwise('/user/listUsers');
});
Whats happening is this that user.html is my parent file which is loaded inside index.html and editUser.html, getUserDealer.html and userLists.html etc are its children which I load within user.html using ui-view.
And I provide the links for nested pages as:
<ul class="nav navbar-nav">
<li>NEW USER</li>
<li>GET USER</li>
</ul>
This can be extended to additional parents and their children as per the need.
Hope it helps!!
Is it possible to create an HTML fragment in an AngularJS controller and have this HTML shown in the view?
This comes from a requirement to turn an inconsistent JSON blob into a nested list of id: value pairs. Therefore the HTML is created in the controller and I am now looking to display it.
I have created a model property, but cannot render this in the view without it just printing the HTML.
Update
It appears that the problem arises from angular rendering the created HTML as a string within quotes. Will attempt to find a way around this.
Example controller :
var SomeController = function () {
this.customHtml = '<ul><li>render me please</li></ul>';
}
Example view :
<div ng:bind="customHtml"></div>
Gives :
<div>
"<ul><li>render me please</li></ul>"
</div>
For Angular 1.x, use ng-bind-html in the HTML:
<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
At this point you would get a attempting to use an unsafe value in a safe context error so you need to either use ngSanitize or $sce to resolve that.
$sce
Use $sce.trustAsHtml() in the controller to convert the html string.
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml(someHtmlVar);
ngSanitize
There are 2 steps:
include the angular-sanitize.min.js resource, i.e.:
<script src="lib/angular/angular-sanitize.min.js"></script>
In a js file (controller or usually app.js), include ngSanitize, i.e.:
angular.module('myApp', ['myApp.filters', 'myApp.services',
'myApp.directives', 'ngSanitize'])
You can also create a filter like so:
var app = angular.module("demoApp", ['ngResource']);
app.filter("trust", ['$sce', function($sce) {
return function(htmlCode){
return $sce.trustAsHtml(htmlCode);
}
}]);
Then in the view
<div ng-bind-html="trusted_html_variable | trust"></div>
Note: This filter trusts any and all html passed to it, and could present an XSS vulnerability if variables with user input are passed to it.
Angular JS shows HTML within the tag
The solution provided in the above link worked for me, none of the options on this thread did. For anyone looking for the same thing with AngularJS version 1.2.9
Here's a copy:
Ok I found solution for this:
JS:
$scope.renderHtml = function(html_code)
{
return $sce.trustAsHtml(html_code);
};
HTML:
<p ng-bind-html="renderHtml(value.button)"></p>
EDIT:
Here's the set up:
JS file:
angular.module('MyModule').controller('MyController', ['$scope', '$http', '$sce',
function ($scope, $http, $sce) {
$scope.renderHtml = function (htmlCode) {
return $sce.trustAsHtml(htmlCode);
};
$scope.body = '<div style="width:200px; height:200px; border:1px solid blue;"></div>';
}]);
HTML file:
<div ng-controller="MyController">
<div ng-bind-html="renderHtml(body)"></div>
</div>
Fortunately, you don't need any fancy filters or unsafe methods to avoid that error message. This is the complete implementation to properly output HTML markup in a view in the intended and safe way.
The sanitize module must be included after Angular:
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular-sanitize.js"></script>
Then, the module must be loaded:
angular.module('app', [
'ngSanitize'
]);
This will allow you to include markup in a string from a controller, directive, etc:
scope.message = "<strong>42</strong> is the <em>answer</em>.";
Finally, in a template, it must be output like so:
<p ng-bind-html="message"></p>
Which will produce the expected output: 42 is the answer.
I have tried today, the only way I found was this
<div ng-bind-html-unsafe="expression"></div>
ng-bind-html-unsafe no longer works.
This is the shortest way:
Create a filter:
myApp.filter('unsafe', function($sce) { return $sce.trustAsHtml; });
And in your view:
<div ng-bind-html="customHtml | unsafe"></div>
P.S. This method doesn't require you to include the ngSanitize module.
on html
<div ng-controller="myAppController as myCtrl">
<div ng-bind-html-unsafe="myCtrl.comment.msg"></div>
OR
<div ng-bind-html="myCtrl.comment.msg"></div
on controller
mySceApp.controller("myAppController", function myAppController( $sce) {
this.myCtrl.comment.msg = $sce.trustAsHtml(html);
works also with $scope.comment.msg = $sce.trustAsHtml(html);
I found that using ng-sanitize did not allow me to add ng-click in the html.
To solve this I added a directive. Like this:
app.directive('htmldiv', function($compile, $parse) {
return {
restrict: 'E',
link: function(scope, element, attr) {
scope.$watch(attr.content, function() {
element.html($parse(attr.content)(scope));
$compile(element.contents())(scope);
}, true);
}
}
});
And this is the HTML:
<htmldiv content="theContent"></htmldiv>
Good luck.
Just did this using ngBindHtml by following angular(v1.4) docs,
<div ng-bind-html="expression"></div>
and expression can be "<ul><li>render me please</li></ul>"
Make sure you include ngSanitize in the module's dependencies.
Then it should work fine.
Another solution, very similar to blrbr's except using a scoped attribute is:
angular.module('app')
.directive('renderHtml', ['$compile', function ($compile) {
return {
restrict: 'E',
scope: {
html: '='
},
link: function postLink(scope, element, attrs) {
function appendHtml() {
if(scope.html) {
var newElement = angular.element(scope.html);
$compile(newElement)(scope);
element.append(newElement);
}
}
scope.$watch(function() { return scope.html }, appendHtml);
}
};
}]);
And then
<render-html html="htmlAsString"></render-html>
Note you may replace element.append() with element.replaceWith()
there is one more solution for this problem using creating new attribute or directives in angular.
product-specs.html
<h4>Specs</h4>
<ul class="list-unstyled">
<li>
<strong>Shine</strong>
: {{product.shine}}</li>
<li>
<strong>Faces</strong>
: {{product.faces}}</li>
<li>
<strong>Rarity</strong>
: {{product.rarity}}</li>
<li>
<strong>Color</strong>
: {{product.color}}</li>
</ul>
app.js
(function() {
var app = angular.module('gemStore', []);
app.directive(" <div ng-show="tab.isSet(2)" product-specs>", function() {
return {
restrict: 'E',
templateUrl: "product-specs.html"
};
});
index.html
<div>
<product-specs> </product-specs>//it will load product-specs.html file here.
</div>
or
<div product-specs>//it will add product-specs.html file
or
<div ng-include="product-description.html"></div>
https://docs.angularjs.org/guide/directive
you can also use ng-include.
<div class="col-sm-9 TabContent_container" ng-include="template/custom.html">
</div>
you can use "ng-show" to show hide this template data.
here is the solution make a filter like this
.filter('trusted',
function($sce) {
return function(ss) {
return $sce.trustAsHtml(ss)
};
}
)
and apply this as a filter to the ng-bind-html like
<div ng-bind-html="code | trusted">
and thank to Ruben Decrop
Use
<div ng-bind-html="customHtml"></div>
and
angular.module('MyApp', ['ngSanitize']);
For that, you need to include angular-sanitize.js,
for example in your html-file with
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular-sanitize.js"></script>
Here's a simple (and unsafe) bind-as-html directive, without the need for ngSanitize:
myModule.directive('bindAsHtml', function () {
return {
link: function (scope, element, attributes) {
element.html(scope.$eval(attributes.bindAsHtml));
}
};
});
Note that this will open up for security issues, if binding untrusted content.
Use like so:
<div bind-as-html="someHtmlInScope"></div>
Working example with pipe to display html in template with Angular 4.
1.Crated Pipe escape-html.pipe.ts
`
import { Pipe, PipeTransform } from '#angular/core';
import { DomSanitizer } from '#angular/platform-browser';
#Pipe({name : 'keepHtml', pure : false})
export class EscapeHtmlPipe implements PipeTransform{
constructor(private sanitizer : DomSanitizer){
}
transform(content){
return this.sanitizer.bypassSecurityTrustHtml(content);
}
}
`
2. Register pipe to app.module.ts
import {EscapeHtmlPipe} from './components/pipes/escape-html.pipe';
declarations: [...,EscapeHtmlPipe]
Use in your template
<div class="demoPipe" [innerHtml]="getDivHtml(obj.header) | keepHtml">
getDivHtml() { //can return html as per requirement}
Please add appropriate implementation for getDivHtml in associated component.ts file.
Just simple use [innerHTML], like below:
<div [innerHTML]="htmlString"></div>
Before you needed to use ng-bind-html...
