例子：
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>calc</title> <script> function calcResult() { var num1 = document.getElementById("id1").value; var calctag = document.getElementById("id2").value; var num2 = document.getElementById("id3").value; var result = 0; switch (calctag) { case "+": result = parseInt(num1) + parseInt(num2); break; case "-": result = parseInt(num1) - parseInt(num2); break; case "*": result = parseInt(num1) * parseInt(num2); break; case "/": if (parseInt(num2) == 0) { alert("数字2不能为0"); } else { result = parseInt(num1) / parseInt(num2); } break; default: alert("......"); } document.getElementById("id5").value = result; } </script> </head> <body> <form> 数字1:<input type="text" id="id1" name="num1" /> <select id="id2" name="calc"> <option value="+" selected="selected">加</option> <option value="-">减</option> <option value="*">乘</option> <option value="/">除</option> </select> 数字2:<input type="text" id="id3" name="num2" /> <input type="button" name="is" id="id4" value="=" onclick="calcResult()" /> 结果:<input type="text" id="id5" name="result" /> </form> </body> </html>
