Vue.js Two Way Binding Model Last Updated : 07 Jun, 2022 Comments Improve Suggest changes Like Article Like Report Vue.js is a progressive framework for building user interfaces. The core library is focused on the view layer only and is easy to pick up and integrate with other libraries. Vue is also perfectly capable of powering sophisticated Single-Page Applications in combination with modern tooling and supporting libraries. The v-model directive makes two-way binding between a form input and app state very easy to implement. One can bind a form input element and make it change the Vue data property when the content of the field changes. These concepts can be used in such cases where according to a field value we also want to update some other field values. After recent updates v-model can be used on the child components also, helping developers to make reusable inputs with completely different behaviors. The below examples demonstrate this concept. Example 1: Filename- index.html: HTML <html> <head> <script src= "https://cdn.jsdelivr.net/npm/vue@2/dist/vue.js"> </script> </head> <body> <div id='parent'> <h1 style="color: green;"> GeeksforGeeks </h1> <h3>Two Way Data Binding</h3> <p><Strong>{{text}}</Strong></p> <input v-model="text"> </div> <script src='app.js'></script> </body> </html> Filename- app.js: JavaScript const parent = new Vue({ el : '#parent', data : { text : "Hi" } }) Output: Example 2: Filename- index.html: HTML <html> <head> <script src= "https://cdn.jsdelivr.net/npm/vue@2/dist/vue.js"> </script> </head> <body> <div id='parent'> <h1 style="color: green;"> GeeksforGeeks </h1> <strong>Sex : </strong> <input type="radio" id="m" value="male" v-model="sex"> <label for="male">Male</label> <input type="radio" id="f" value="female" v-model="sex"> <label for="female">Female</label> <input type="radio" id="b" value="bi-sexual" v-model="sex"> <label for="bi-sexual">Bisexual</label> <p><strong>Your Sex: </strong>{{ sex }}</p> </div> <script src='app.js'></script> </body> </html> Filename- app.js: JavaScript const parent = new Vue({ el : '#parent', data : { address:'' } }) Output: Comment More infoAdvertise with us H hunter__js Follow Improve Article Tags : JavaScript Web Technologies Vue.JS Explore JavaScript Tutorial 8 min read JavaScript BasicsIntroduction to JavaScript 4 min read JavaScript Versions 2 min read How to Add JavaScript in HTML Document? 3 min read JavaScript Syntax 6 min read JavaScript Output 4 min read JavaScript Comments 2 min read JS Variables & DatatypesVariables and Datatypes in JavaScript 6 min read Global and Local variables in JavaScript 4 min read JavaScript Let 6 min read JavaScript const 5 min read JavaScript Var Statement 7 min read JS OperatorsJavaScript Operators 5 min read Operator precedence in JavaScript 2 min read JavaScript Arithmetic Operators 5 min read JavaScript Assignment Operators 5 min read JavaScript Comparison Operators 5 min read JavaScript Logical Operators 5 min read JavaScript Bitwise Operators 5 min read JavaScript Ternary Operator 4 min read JavaScript Comma Operator 2 min read JavaScript Unary Operators 4 min read JavaScript in and instanceof operators 3 min read JavaScript String Operators 3 min read JS StatementsJavaScript Statements 4 min read JavaScript if-else 3 min read JavaScript switch Statement 4 min read JavaScript Break Statement 2 min read JavaScript Continue Statement 1 min read JavaScript Return Statement 4 min read JS LoopsJavaScript Loops 3 min read JavaScript For Loop 4 min read JavaScript While Loop 3 min read JavaScript For In Loop 3 min read JavaScript for...of Loop 3 min read JavaScript do...while Loop 4 min read JS Perfomance & DebuggingJavaScript | Performance 4 min read Debugging in JavaScript 4 min read JavaScript Errors Throw and Try to Catch 2 min read JS ObjectObjects in Javascript 4 min read Object Oriented Programming in JavaScript 3 min read JavaScript Objects 6 min read Creating objects in JavaScript 5 min read JavaScript JSON Objects 3 min read JavaScript Object Reference 4 min read JS FunctionFunctions in JavaScript 4 min read How to write a function in JavaScript ? 4 min read JavaScript Function Call 2 min read Different ways of writing functions in JavaScript 3 min read Difference between Methods and Functions in JavaScript 3 min read Explain the Different Function States in JavaScript 3 min read JavaScript Function Complete Reference 3 min read JS ArrayJavaScript Arrays 7 min read JavaScript Array Methods 7 min read Best-Known JavaScript Array Methods 6 min read Important Array Methods of JavaScript 7 min read JavaScript Array Reference 4 min read Like
