货币输入框
第二步：引用JavaScript(moneyinput.js)文件<script src="moneyinput.js" type="text/javascript" ></script>
第二步：在需要输入框处，加入以下代码就可以了。
<input type="text"id="price"name="price" style="text-align:right"onKeyUp="nst(this,'ccc')" value="￥0"title="请输入产品价格"/><!-- 处input用于显示大写人民币 如不想显示，直接将type="hidden",显示type="text" --><input name="ccc" type="hidden" size="55" readonly/>
