This time I will bring you detailed instructions for using jointjs in vue. What are the precautions for using jointjs in vue? The following is a practical case, let's take a look.
After reading this article, you should at least have a rough idea of how to do it. Let’s take a look at it in detail:
First run npm install jointjs --save
## in the vue project #Then add the following two lines to theentry file, mine is main.js, or it may be app.js, and use joint.js and jquery as global variables
window.$ = require('jquery'); window.joint = require('jointjs');You need to pay attention here What's interesting is that joint.js relies on backbone, jquery and lodash. When introducing it through script, you need to import these files one by one, but it is not necessary when using npm of vue. The joint.js introduced by npm has already encapsulated these files by default. It is not enough to introduce it in this way. You may encounter the problem that the diagram can be loaded normally, but cannot be dragged. When encountering these problems, it is usually caused by the conflict between joint.js and the environment in your own vue project, resulting in the inability to read. Fetch or read error. I installed element, iview, axios, vuex, and jquery in my original project. After installing joint.js, jointjs could not be loaded normally. Later, I rebuilt a project and only installed element, axios, and vuex. , in order to avoid conflicts between jquery and jquery in joint.js, jquery was not installed later. Is this enough? Can I run the example in the link above? Like this:
<template> <p> </p> <h1 id="Home">Home</h1> <p></p> </template> <script> export default { created() { let graph = new joint.dia.Graph; let paper = new joint.dia.Paper({ el: $('#myholder'), width: 600, height: 200, model: graph, gridSize: 1 }); let rect = new joint.shapes.basic.Rect({ position: { x: 100, y: 30 }, size: { width: 100, height: 30 }, attrs: { rect: { fill: 'blue' }, text: { text: 'my box', fill: 'white' } } }); let rect2 = rect.clone(); rect2.translate(300); let link = new joint.dia.Link({ source: { id: rect.id }, target: { id: rect2.id } }); graph.addCells([rect, rect2, link]); } } </script>NoNoNo, notice that the rendering is placed in the In other words, the code will become like this:
<template> <p> </p> <p></p> </template> <script> export default { methods:{ click_joint() { let graph = new joint.dia.Graph; let paper = new joint.dia.Paper({ el: $('#myholder'), width: 600, height: 200, model: graph, gridSize: 1 }); let rect = new joint.shapes.basic.Rect({ position: { x: 100, y: 30 }, size: { width: 100, height: 30 }, attrs: { rect: { fill: 'blue' }, text: { text: 'my box', fill: 'white' } } }); let rect2 = rect.clone(); rect2.translate(300); let link = new joint.dia.Link({ source: { id: rect.id }, target: { id: rect2.id } }); graph.addCells([rect, rect2, link]); } } } </script>To point out, just install jointjs when introduced through npm Yes, there is no need to install lodash, backbone, jquery, or import the joint.css file into the page. The author previously introduced joint.js through script. I tried many times without success. I kept getting errors when reading the joint.js file. If other friends try successfully, please feel free to share. I believe you have mastered the method after reading the case in this article.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
