一款jquery实现简单计算器代码。该jquery计算器使用 Bootstrap 4进行布局，并结合math.js数学库，实现简单的加减乘除和平方，开方等数学计算。在页面中引入bootstrap 4，jquery和math.min.js文件。以及计算器的样式文件style.css和main.js文件。<link href="path/to/bootstrap-4.0.0-beta.min.css" rel="stylesheet"> <link href="path/to/font-awesome.min.css" rel="stylesheet"> <link href="path/to/style.css" rel="stylesheet"><script src="path/to/jquery.js"></script><script src="path/to/bootstrap-4.0.0-beta.min.js"></script><script src="path/to/math.min.js"></script><script src="path/to/main.js"></script>该jquery计算器的HTML结构如下：<div class="container"> <!-- Rounded switch --> <label class="switch"> <input type="checkbox"> <span class="slider"></span> </label> <form> <input readonly id="display1" type="text" class="form-control-lg text-right"> <input readonly id="display2" type="text" class="form-control-lg text-right"> </form> <div class="d-flex justify-content-between button-row"> <button id="left-parenthesis" type="button" class="operator-group">(</button> <button id="right-parenthesis" type="button" class="operator-group">)</button> <button id="square-root" type="button" class="operator-group">√</button> <button id="square" type="button" class="operator-group">x2</button> </div> <div class="d-flex justify-content-between button-row"> <button id="clear" type="button">C</button> <button id="backspace" type="button">?</button> <button id="ans" type="button" class="operand-group">Ans</button> <button id="divide" type="button" class="operator-group">÷</button> </div> <div class="d-flex justify-content-between button-row"> <button id="seven" type="button" class="operand-group">7</button> <button id="eight" type="button" class="operand-group">8</button> <button id="nine" type="button" class="operand-group">9</button> <button id="multiply" type="button" class="operator-group">×</button> </div> <div class="d-flex justify-content-between button-row"> <button id="four" type="button" class="operand-group">4</button> <button id="five" type="button" class="operand-group">5</button> <button id="six" type="button" class="operand-group">6</button> <button id="subtract" type="button" class="operator-group">?</button> </div> <div class="d-flex justify-content-between button-row"> <button id="one" type="button" class="operand-group">1</button> <button id="two" type="button" class="operand-group">2</button> <button id="three" type="button" class="operand-group">3</button> <button id="add" type="button" class="operator-group">+</button> </div> <div class="d-flex justify-content-between button-row"> <button id="percentage" type="button" class="operand-group">%</button> <button id="zero" type="button" class="operand-group">0</button> <button id="decimal" type="button" class="operand-group">.</button> <button id="equal" type="button">=</button> </div></div>
