怎样将钱数转换成汉字？

[yxxcrtd]

比如： 23.56 要转换成 二十三元零五十六分 元整

如何控制一个文本框中只能输入汉字？

上面是两个方法.请楼主参考下.
如何控制一个文本框中只能输入汉字？
如果是网页,那就用文本框的onChange()或onBlur()事件加上正则表达式来处理吧.

收藏一下 呵呵

谢谢黑哥了

另如果要做成js的，那你翻译下就OK了。

转个实例：
<script>
function regInput(reg)
{
var srcElem = event.srcElement
var oSel = document.selection.createRange()
oSel = oSel.duplicate()
oSel.text = ""
var srcRange = srcElem.createTextRange()
oSel.setEndPoint("StartToStart", srcRange)
var num = oSel.text + String.fromCharCode(event.keyCode) + srcRange.text.substr(oSel.text.length)
event.returnvalue = reg.test(num)
}

function chineseNumber(num)
{
if (isNaN(num) || num > Math.pow(10, 12)) return ""
var cn = "零壹贰叁肆伍陆柒捌玖"
var unit = new Array("拾佰仟", "分角")
var unit1= new Array("万亿", "")
var numArray = num.toString().split(".")
var start = new Array(numArray[0].length-1, 2)

function toChinese(num, index)
{
var num = num.replace(/\d/g, function ($1)
{

return num
}

}

}

Thanks： lydvqq(碧水情缘♀黑哥) ！

关于 金额转换，我是想用在页面中反映，就是当用户输入一个数字之后，后面的一个文本框中会马上出项转换后的汉字...

这能用 javascript 实现吗？

学习下，收藏！
