jss 文件中的 Javascript 警报功能

发布于 2024-12-09 13:19:37 字数 1106 浏览 0 评论 0原文

我有一个问题，当我单击网页上的按钮时，我想在警报框中显示一堆变量。

我不想在 XHTML 文件中创建一堆变量然后输出这些变量，因为我已经计算了 javascript 文件中的所有内容。我将 Javascript 文件引用到我的 XHTML 文件，如果我只是做一个普通的 document.write ，变量就会显示出来。

变量只是我根据一系列值计算的数字。当我单击网页本身上的按钮时，我想将它们显示在警报框中。现在，当我访问网页时，我可以在警报框中显示它们，但是当我单击按钮时，我不知道如何显示它们。

例如：

我的 .jss 文件包含以下内容：

var num5 = 5;
var num6 = 6;
var num7 = 7;
var num8 = 8;
var num9 = 9;
var num10= 10;

我的 xhtml 文件：

<?xml version = "1.0" encoding = "utf-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http://www.w3.org/TR/xhtmll/DTD/xhtmll-strict.dtd">

 <html xmlns = "http://www.w3.org/1999/xhtml">
    <head>
        <title>ShowNums.html</title>
    </head>
    <body>
        <script type = "text/javascript" src = "test.js">
        </script>
        <input type="button" onclick="show_alert()" value="Click" />    
    </body>
</html>

我将 .jss 文件引用到 XHTML 文件并希望显示这些数字。我可以轻松地将它们编码到警报中，但我宁愿有一个弹出警报框，当用户单击按钮（即“单击”按钮）时会显示它们。我该怎么做？我尝试寻求帮助，但似乎找不到：\

I have a problem where I want to show a bunch of variables in an alert box when I click on a button on the webpage.

I don't want to create a bunch of variables in a XHTML file and then output those since I already calculated everything in my javascript file. I referenced the Javascript file to my XHTML file and the variables show up if i just do a plain document.write

The variables are just numbers I calculated on a range of values. I want to display them in an alert box when I click on a button on the webpage itself. Now I can display them in an alert box when I go to the webpage, but I can't figure out how to display them when I click on a button.

For example,:

My .jss file contains the following:

var num5 = 5;
var num6 = 6;
var num7 = 7;
var num8 = 8;
var num9 = 9;
var num10= 10;

My xhtml file:

<?xml version = "1.0" encoding = "utf-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http://www.w3.org/TR/xhtmll/DTD/xhtmll-strict.dtd">

 <html xmlns = "http://www.w3.org/1999/xhtml">
    <head>
        <title>ShowNums.html</title>
    </head>
    <body>
        <script type = "text/javascript" src = "test.js">
        </script>
        <input type="button" onclick="show_alert()" value="Click" />    
    </body>
</html>

I referenced my .jss file to my XHTML file and want to display those numbers. I can easily encode them into an alert but I would rather have a popup alert box that would display them when the user clicks on a button(i.e. the Click button). How would I do this? I tried looking for help but I can't seem to find it :\

您只是在寻找这个 show_alert() 函数吗？

function show_alert() {
    var msg = num5 + ", " + num6 + ", " + num7 + ", " + num8 + ", " + num9 + ", " + num10;
    alert(msg);    // shows "5, 6, 7, 8, 9, 10"
}

Are you just looking for this show_alert() function?

function show_alert() {
    var msg = num5 + ", " + num6 + ", " + num7 + ", " + num8 + ", " + num9 + ", " + num10;
    alert(msg);    // shows "5, 6, 7, 8, 9, 10"
}
