I am writing because i have an issue using vue.js,
this is my index.html code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js">
</script>
<h1> Prova VUE </h1>
<div id="app">
<p> Login:</p>
<button v-on : click="getInfo">OK</button>
</div>
<script>
var app = new Vue({
el: '#app',
data: {
cordocs: [],
docenti: [],
link : '/newProvaTweb/hello-servlet'
},
methods:{
getInfo:function(){
var self = this;
$.get(this.link,{
action: "initialization"
}, function (data) {
self.cordocs = data[0];
});
}
}
});
</script>
I have included the script but, working with intellij doesn't recognize the vue component like this,
and it doesn't work. Someone know how to solve this problem?

Hi i Have a problem with MathJax library. I want to display the mathjax formula on the screen, but when I use window.MathJax I get the error that it is undefined. Here is how I installed the MathJax in my html file:
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>Test</title>
<link rel="icon" href="/icons/favicon.ico" type="image/x-icon">
<link rel="shortcut icon" href="/icons/favicon.ico" type="image/x-icon">
<!-- inject:css -->
<!-- endinject -->
<script type="text/x-mathjax-config">
MathJax = {
options: {
renderActions: {
addMenu: []
}
},
};
MathJax.Hub.Config({
tex2jax: {
inlineMath: [ ['$','$'], ["\\(","\\)"] ],
processEscapes: true
}
});
</script>
<script async type="text/javascript" src="https://cdn.jsdelivr.net/npm/mathjax#3/es5/tex-mml-svg.js"></script>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no"/>
</head>
<body>
<div id="application-content">
</div>
</body>
<!-- inject:js -->
<!-- endinject -->
<script type="application/javascript">
EMBED.default.init();
</script>
</html>
And here is the component where I use the library:
import React, { Component } from 'react';
export default class MathBlock extends Component {
constructor(props) {
super(props);
this.state = {
open: false,
};
}
render() {
const text = this.props.block.getText();
const latexRegex = /\${2}(.*?)\${2}/;
const hasLatex = latexRegex.test(this.props.block.getText());
return (
<div>
<div
dangerouslySetInnerHTML={{
__html: hasLatex
? window.MathJax.tex2svg(text.replaceAll('$', '')).innerHTML
: window.MathJax.mathml2svg(text).innerHTML,
}}
/>
</div>
);
}
}
MathBlock.propTypes = {
block: React.PropTypes.object.isRequired,
};
Does anyone know what is the problem here?
Because the script tag that loads MathJax has the async attribute, it may not be loaded when your EMBED.default.init(); command likely will run before MathJax is loaded, and so before window.MathJax has been defined.
You could either remove the async attribute (which will mean your page will have to wait for MathJax to load and compile before the rest of the page is processed, slowing down your initial view of the page), or you could put the EMBED.default.init(); in MathJax's startup ready() function so that it is not performed until MathJax is loaded.
You are loading MathJax version 3, but your current configuration seems to be a mix of v2 and v3 configurations, and it is currently being ignored entirely by MathJax.
You could use
<script>
MathJax = {
options: {
renderActions: {
addMenu: []
}
},
tex: {
inlineMath: [ ['$','$'], ["\\(","\\)"] ],
processEscapes: true
},
startup: {
ready() {
MathJax.startup.defaultReady();
EMBED.default.init();
}
}
};
</script>
(a correct v3 configuration) in place of your current configuration script, and see if that avoids the problem.
I am trying to generate an iron-ajax request and run a test on its response in Polymer 2.x with using the Mocha test suite.
However, when running this test I get the following error:
Cannot read property 'generateRequest' of undefined Context. at my-test.html:25

How can I make an AJAX request and handle the response in this framework?
I would advice to use fetch for this. It also will send an ajax call and is native to your browser.

return res.json()

Hi I am new for AngularJs, I am trying to navigate from one page to another when tapped on button and I followed the below code for my requirement but it's not working.
Html files--->
index.html,main.html,london.html,paries.html,others.html
Js files-->
AngularFile.js,Others.js
I kept button on london.html file.
When I taped on it I wanted to navigate from london.html file to others.html file, but where did I make a mistake?
Can some on help me please?
index.html:-
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-route.js"></script>
<head>
<script src="angularFile.js"></script>
<script type="others.js"></script>
</head>
<body ng-app="myApp">
<p>main</p>
City 1
City 2
<p>Click on the links.</p>
<p>Note that each "view" has its own controller which each gives the "msg" variable a value.</p>
<div ng-view></div>
</body>
</html>
london.html:
{{msg}}
<input type="Button" ng-click="changeMe()" value="Go to other"/>
others.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1>Wel come to Others page</h1>
</body>
</html>
angularFile.js
var app = angular.module("myApp", ["ngRoute"]);
app.config(function($routeProvider) {
$routeProvider
.when("/main", {
templateUrl : "main.htm",
})
.when("/london", {
templateUrl : "london.htm",
controller : "londonCtrl"
})
.when("/paris", {
templateUrl : "paris.htm",
controller : "parisCtrl"
});
});
others.js:
app.controller("londonCtrl", function ($scope,$location) {
$scope.msg = "I love London";
$scope.changeMe = function(){
$location.path('/others')
};
})
;
You need to register the view in the $routeProvider setup
app.config(function($routeProvider) {
$routeProvider
.when("/main", {
templateUrl : "main.htm",
})
.when("/london", {
templateUrl : "london.htm",
controller : "londonCtrl"
})
.when("/others", {
templateUrl : "others.html"
})
.when("/paris", {
templateUrl : "paris.htm",
controller : "parisCtrl"
});
});
then go to it $location.path('/others');
Here's a sample plunker
I am relatively new to Angularjs, and am building a website. When I try to inject todo.html into the body tags of index.html nothing happens. I am not getting any errors in the console. I have read many of the similar posts to mine, and have already tried
Remove the ng-include from the body of index.html
Moved the links for angualrjs and bootstrap from the body of index.html to the head
Originally I used Ng-route but it did not work, so I implemented ui-router
I have tried both ng-route and ui-router,and both run without any errors. I don't think it has anything to do with either.
index.html

App.js
var todoApp = angular.module('todoApp', [
'ui.router'
]);
todoApp.config(function ($stateProvider, $urlRouterProvider) {
$stateProvider
.state('todo', {
url: "/",
templateUrl: 'views/todo.html',
controller: 'TodoController'
})});
todo.controller.js
todoApp.controller('TodoController', ['$scope', 'Todos', function TodoController($scope, Todos) {
$scope.formData = {};
console.log("in the TodoController");
// when landing on the page, get all todos and show them
Todos.get()
.success(function(data) {
$scope.todos = data;
});
// when submitting the add form, send the text to the spring API
$scope.createTodo = function() {
if(!$scope.todoForm.$valid) {
return;
}
Todos.create($scope.formData)
.success(function(data) {
$scope.formData = {}; // clear the form so our user is ready to enter another
$scope.todos.push(data);
});
};
// delete a todo after checking it
$scope.deleteTodo = function(id) {
Todos.delete(id)
.success(function(data) {
angular.forEach($scope.todos, function(todo, index){
if(todo.id == id) {
$scope.todos.splice(index, 1);
}
});
});
};
// when submitting the add form, send the text to the node API
$scope.saveTodo = function(todo) {
Todos.update(todo)
.success(function(data) {
$scope.editedTodo = {};
});
};
$scope.editedTodo = {};
$scope.editTodo = function(todo) {
$scope.editedTodo = todo;
}
$scope.revertTodo = function() {
$scope.editedTodo = {};
}
}]);
You should be using otherwise to force the first state to be loaded as below
app.config(function ($stateProvider, $urlRouterProvider) {
$stateProvider
.state('todo', {
url: "/",
templateUrl: 'todo.html',
})
$urlRouterProvider.otherwise('/');
});
Your index.html will look like
<div ng-include="'app/views/header.html'"></div>
<ui-view>
</ui-view>
LIVE DEMO
I added the code posted by #Aravind to my project which I belive was an improvement on my own and was correct. But the issue was the file path to the todo.html. The file path in the original was views/todo.html
the correct path is app/views/todo.html
My original code:
todoApp.config(function ($stateProvider, $urlRouterProvider) {
$stateProvider
.state('todo', {
url: "/",
templateUrl: 'views/todo.html',
controller: 'TodoController'
})});
Current Working Code
todoApp.config(function ($stateProvider, $urlRouterProvider) {
$stateProvider
.state('todo', {
url: "/",
templateUrl: 'app/views/todo.html',
})
$urlRouterProvider.otherwise('/');
});
I'm just starting out with Angular and most of programming in general. I'm trying to make a separate view1.html file appear on my index.html page but it won't, so I'm assuming it's a routing problem. I tried pasting the view1.html content in the body of my index.html to test it and it wasn't showing the controller content either. I'm sure they're simple mistakes but I can't find them. view.html is in a separate folder called views. I only have the javascript in the index.html page for convenience.

You need to include the script for angular's router.
<head>
<meta charset="UTF-8">
<title>First Angular App</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.11/angular.min.js"></script>

Also, looks like you're missing a closing </head> tag.
Here's a working version of your HTML file:
