文本框...现在我想将两个价格加在一起，得到一个总额为
的bloank文本框..
我得到了这个关闭一个网站的示例..但它不显示
十进制数，它只显示整数
请帮助
var number1 = parseInt（document.forms [0] .CasesSellingPrice.value）;
var number2 = parseInt（document.forms [0] .AccessoriesSellingPrice.value）;
document.forms [0] .total.value = number1 + number2;
Right, ok, well I have designed a form that will display a price (22.34) in
a text box, and another price in the other text box... I also have a blank
text box... Now I want to add both the prices together and get a total in

I got this example off a website sumwhere.. But it does not display the
decimal number, it only displays the whole number
PLEASE HELP

阅读常见问题解答。全部，但特别是
http：// www .jibbering.com / faq / #FAQ4_21
var number1 = + document.forms [0] .CasesSellingPrice.value;
var number2 = + document.forms [0] .AccessoriesSellingPrice.value;
document.forms [0] .total.value = number1 + number2;
And，为什么你使用表单元素的混合访问器？尝试
保持统一：
var number1 = + document.forms [0] .elements [''CasesSellingPrice'']。value;
var number2 = + document.forms [0] .elements [''AccessoriesSellingPrice'']。value;
document.forms [0] .elements [''total'' ] .value = number1 + number2;
更好，但用表格名称/ id替换0会更好。

Read the FAQ. All of it, but especially
http://www.jibbering.com/faq/#FAQ4_21
var number1 = +document.forms[0].CasesSellingPrice.value;
var number2 = +document.forms[0].AccessoriesSellingPrice.value;
document.forms[0].total.value = number1 + number2;
And, why are you using mixed accessors for the form elements? Try to
keep it uniform:
var number1 = +document.forms[0].elements[''CasesSellingPrice''].value;
var number2 = +document.forms[0].elements[''AccessoriesSellingPrice''].value;
document.forms[0].elements[''total''].value = number1 + number2;
Is better but replacing the 0 with the forms name/id would be even better.

我发现它实际上很有趣。如果没有完整的脚本（它的内容很长），请仔细阅读前5或6行重要内容：
< script language =" javascript">
应该是type =" text / javascript"，但由于它似乎是在2001年修改的最后一个
，因此它无关紧要。
<！ - 从没有javascript的浏览器中隐藏。
也不需要HTML评论实体。我想如果你浏览一个10年的b
岁的浏览器，可能需要它。
函数FormatNumber（数字，小数，分隔符）
{
不确定我是否想要一个名为Number的变量（参数）。
NumToFormat似乎更好，更直观。

Decimals = Decimals.toString（）也许？不过可能是马车，我不记得了。

似乎要短得多（尽管它缺少一些上面的
功能）并且更容易理解。
这些都没有回答/解决OP的原始问题。在这个主题中看到我的
之前的回复。

I found it funny actually. Without going through the entire script (its
inherently long), lets go through the first 5 or 6 significant lines:
<script language="javascript">
Should be type="text/javascript", but since it appears to have been last
modified in 2001, its not relevant.
<!-- Hide from browsers without javascript.
Nor is the HTML comment entity needed. I guess if you browse with a 10
year old browser it might be needed.
function FormatNumber(Number,Decimals,Separator)
{
Not sure that I would want a variable (parameter) named Number.
NumToFormat seems better and more intuitive.
// ************************************************** ********

//
// October 28, 2001 -- Modified to provide leading 0 for fractional number
// less than 1.
//
// This function accepts a number to format and number
// specifying the number of decimal places to format to. May
// optionally use a separator other than ''.'' if specified.
//
// If no decimals are specified, the function defaults to
// two decimal places. If no number is passed, the function
// defaults to 0. Decimal separator defaults to ''.'' .
//
// If the number passed is too large to format as a decimal
// number (e.g.: 1.23e+25), or if the conversion process
// results in such a number, the original number is returned
// unchanged.
// ************************************************** ********
Number += "" // Force argument to string.
Decimals += "" // Force argument to string.
Separator += "" // Force argument to string.
Decimals = Decimals.toString() perhaps? Might be buggy though, I don''t
remember.
http://www.jibbering.com/faq/#FAQ4_6
Seems to be a heck of a lot shorter (although it lacks some of the
functionality in the above) and a lot easier to follow.
None of which answers/addresses the OP''s original problem. See my
previous reply in this thread.
