Question

任何人都可以告诉以下代码中的问题...当我在浏览器中运行程序时出现一个空白的白色屏幕...我不知道为什么它不起作用...我不是很确定语法...
我不想通过任何事件调用该函数..我只想编写一个函数并通过手动调用来调用它...

    <html>
    <head>
        <script language="javascript" type="text/javascript">
            function salin()
            {
                var sal = prompt("Enter your current salary - ","");
                var in = prompt("Enter the increment % - ","");

                sal = parseInt(sal);
                in = parseInt(in);

                var nsal = sal +( sal*(in /100));

                alert("Your new salary is - " + nsal);
            }

         salin();
      </script>
    </head>

    <body>
    </body>
    </html>

Answer 1

问题似乎出在这一行in = parseInt(in);

in是javascript中的保留关键字，用于返回布尔值。将其替换为其他变量名称

Answer 2

我创造了这个小提琴......

它的工作。您使用的是保留的javascript关键字

function salin()
            {
                var sal = prompt("Enter your current salary - ","");
                var values = prompt("Enter the increment % - ","");

                sal = parseInt(sal);
                values = parseInt(values);

                var nsal = sal +( sal*(values /100));

                alert("Your new salary is - " + nsal);
            }

         salin();

Answer 3

请改为尝试：

function salin()
        {

                            var sal = prompt("Enter your current salary - ","");
            var income = prompt("Enter the increment % - ","");

            sal = parseInt(sal);
            income = parseInt(income);

            var nsal = sal +( sal*(income /100));

            return "Your new salary is - " + nsal;
        }

     alert(salin());

注意我添加了return并将alert()放在函数调用上。我也将“in”改为“income”

＆＃39;在＆＃39;是保留关键字。将其更改为其他变量名称

       <body>

    <script language="javascript" type="text/javascript">
        function salin()
        {
            var sal = prompt("Enter your current salary - ","");
            var in1 = prompt("Enter the increment % - ","");

            sal = parseInt(sal);
            in1 = parseInt(in1);

            var nsal = sal +( sal*(in1 /100));

            alert("Your new salary is - " + nsal);
        }

     salin();
  </script>



</body>

函数没有在javascript中调用
