特别是进行财务相关的项目时,一般客户都希望会有大小写的转换功能. 现在提供一个js代码,
来源不详.
资源共享嘛,有现成的就没必要再自己去写了,呵呵!
我自己实验了一下,还可以,现在发布出来,以方便大家.

源代码如下:
<script>

}
</script>
<input id=up size=60 onkeypress="regInput(/^\d{0,12}(\.\d{0,2})?$/)"><button onclick="lw.value = chineseNumber(up.value)">转为大写</button><br>
<input id=lw size=60 value="壹仟壹佰壹拾壹圆整"><button onclick="up.value = aNumber(lw.value)">转为小写</button>
我自己在.net下测试了一下,小写转大写没问题,但大写转小写就有点问题了.
我把它写在了一个js文件里了.
