数字金额转换中文大写

Posted 2020-09-10 态度决定高度

<script type="text/javascript" language="javascript">

JS处理部分写好了，那么是如何调用呢？往下看，同样简单：假设要在下面的div中显示大写金额，可以这样调用：

1	<div><b>已付金额总额(大写):</b><script language="javascript">document.write(Arabia_to_Chinese("3,060.00"));</script></div>

也就是把需要转换大写金额的小写数字输入在Arabia_to_Chinese()函数中，然后用javaScript的document.write方法显示在网页上。
