时间/距离转换器帮助（ptII） [英] Time/distance converter help (ptII)
问题描述
继我最近在这个新闻组发表的帖子中，我得承认我是b $ b挣扎。我没有使用javascript或它的工作经验。我想要的是一个简单的转换器，允许用户输入行进的距离
以英里为单位的
以及以小时和分钟为单位的时间，结果是平均值
速度。我会感激的是有人为我写剧本，如果可能的话，请在这里发布
。我愿意学习，但不知道从哪里开始
，我找不到任何能帮助我的教程！
谢谢.. .Andre
Further to my recent post in this newsgroup i''ve got to admit i''m
struggling. I''ve no experience with javascript or it''s workings. What i''d
like is a simple converter to allow a user to input the distance travelled
in miles and the time in hours and minutes, the result being an average
speed. What i''d appreciate is for someone to write the script for me and
post here if possible. I am willing to learn but don''t know where to start
and i''ve found no tutorial that will help me!
Thanks...Andre

假设您想在网页中运行此脚本：
< html>
< head>
< title>将距离和时间转换为速度< / title>
< script type =" text / javascript">
函数Calculate（）{
var theDistance = new Number（document.forms [''theForm''] .txtDistance.value）;
var theTimeUsed = new Number（document.forms [''theForm'']。txtTimeUsed.value）;
if（！NaN（theDistance） ）&&！NaN（theTimeUsed）&&（theTimeU sed> 0））{
document.forms [''theForm'']。txtResult =（theDistance /（theTimeUsed / 60） ））;
返回true;
}
返回false;
}
< / script>
< / head>

< form name =" theForm" ID = QUOT; theForm"行动= QUOT;＃" onsubmit =" Calculate（）;返回

Assuming you want to run this script in a web page:

<head>
<title>Converting distance and time into speed</title>
<script type="text/javascript">
function Calculate() {
var theDistance = new
Number(document.forms[''theForm''].txtDistance.value);

if(!NaN(theDistance)&&!NaN(theTimeUsed)&&(theTimeU sed>0)) {
document.forms[''theForm''].txtResult = (theDistance /
(theTimeUsed/60));
return true;
}
return false;
}
</script>
</head>
<body>
<h1>Converting distance and time into speed</h1>
<form name="theForm" id="theForm" action="#"
onsubmit="Calculate();return false;">
<fieldset><legend>Enter information:</legend>
