Using jQuery to add and delete the input box group input-group based on Bootstrap_javascript skills
This article shares an example of using jQuery to implement the adding and deleting operations of the input box group input-group for your reference. The specific content is as follows
Note that this requires the use of the input box group of the Bootstrap framework, such as:
<div class="row"> <div class="col-lg-6"> <div class="input-group"> <span class="input-group-addon"> <input type="checkbox" aria-label="..."> </span> <input type="text" class="form-control" aria-label="..."> </div><!-- /input-group --> </div><!-- /.col-lg-6 --> <div class="col-lg-6"> <div class="input-group"> <span class="input-group-addon"> <input type="radio" aria-label="..."> </span> <input type="text" class="form-control" aria-label="..."> </div><!-- /input-group --> </div><!-- /.col-lg-6 --> </div><!-- /.row -->
Rendering of Demo case:
Here provides the self-made plug-in inputGroup.js
The parameter can set whether the middle control in the input box group is a text field or an input box; and set the content of the operation on the right side of the input box group.
To use inputGroup.js, just add a selector in the corresponding container, such as a div, then use jQuery to obtain the jQuery object corresponding to the selector, and call the initInputGroup method.
inputGroup.js
/** * Created by DreamBoy on 2016/4/29. */ $(function() { $.fn.initInputGroup = function (options) { //1.Settings 初始化设置 var c = $.extend({ 'widget' : 'input', 'add' : "<span class=\"glyphicon glyphicon-plus\"></span>", 'del' : "<span class=\"glyphicon glyphicon-minus\"></span>" }, options); var _this = $(this); //添加序号为1的输入框组 addInputGroup(1); /** * 添加序号为order的输入框组 * @param order 输入框组的序号 */ function addInputGroup(order) { //1.创建输入框组 var inputGroup = $("<div class='input-group' style='margin: 10px 0'></div>"); //2.输入框组的序号 var inputGroupAddon1 = $("<span class='input-group-addon'></span>"); //3.设置输入框组的序号 inputGroupAddon1.html(" " + order + " "); //4.创建输入框组中的输入控件(input或textarea) var widget = '', inputGroupAddon2; if(c.widget == 'textarea') { widget = $("<textarea class='form-control' style='resize: vertical;'></textarea>"); inputGroupAddon2 = $("<span class='input-group-addon'></span>"); } else if(c.widget == 'input') { widget = $("<input class='form-control' type='text'/>"); inputGroupAddon2 = $("<span class='input-group-btn'></span>"); } //5.创建输入框组中最后面的操作按钮 var addBtn = $("<button class='btn btn-default' type='button'>" + c.add + "</button>"); addBtn.appendTo(inputGroupAddon2).on('click', function() { //6.响应删除和添加操作按钮事件 if($(this).html() == c.del) { $(this).parents('.input-group').remove(); } else if($(this).html() == c.add) { $(this).html(c.del); addInputGroup(order+1); } //7.重新排序输入框组的序号 resort(); }); inputGroup.append(inputGroupAddon1).append(widget).append(inputGroupAddon2); _this.append(inputGroup); } function resort() { var child = _this.children(); $.each(child, function(i) { $(this).find(".input-group-addon").eq(0).html(' ' + (i + 1) + ' '); }); } } });
Demo case——InputGroupDemo
The directory structure is as follows:
index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>输入框组</title> <link rel="stylesheet" href="css/bootstrap.min.css" type="text/css"> <style> /*.input-group-add .input-group { margin: 10px 0; }*/ </style> <!--<link href="assets/font-awesome/css/font-awesome.css" rel="stylesheet" />--> <!--[if lt IE 9]> <script src="js/html5shiv.js"></script> <script src="js/respond.min.js"></script> <![endif]--> </head> <body> <div class="container"> <div class="input-group-add"> <!--<div class="input-group"> <span class="input-group-addon"> 1 </span> <!–<input type="text" class="form-control" aria-label="...">–> <textarea class="form-control"></textarea> <span class="input-group-addon"> <button class="btn btn-default" type="button"> + </button> </span> </div>--> </div> </div> <script src="js/jquery-1.11.1.min.js"></script> <script src="js/bootstrap.min.js"></script> <script src="inputGroup.js"></script> <script> $(function() { $('.input-group-add').initInputGroup({ 'widget' : 'textarea', //输入框组中间的空间类型 /*'add' : '添加', 'del' : '删除'*/ }); }); </script> </body> </html>
If the middle control in the input box group requires input, you can set:
$('.input-group-add').initInputGroup({ 'widget' : 'input', //输入框组中间的空间类型 /*'add' : '添加', 'del' : '删除'*/ });
Or do not set it, because the default middle control is input.
The effect of the middle control being input is as follows:
The above is the entire content of this article, I hope it will be helpful to everyone’s study.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

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.
