金额小写转换为大写脚本

1.脚本

<script type="text/jscript">
    $(function () {
        $("#<%=txtFundingEstimatesUpper.ClientID %>").val(ConvertMoney($("#<%=txtFundingEstimates.ClientID %>").val()));
        //金额变化时转为大写    
        $("#<%=txtFundingEstimates.ClientID %>").bind("input propertychange", function () {
            var upperMoney = ConvertMoney($(this).val());
            $("#<%=txtFundingEstimatesUpper.ClientID %>").val(upperMoney);
        });
    });

    function ConvertMoney(strg) {
        strg = strg.replace(/,/g, "");
        var number = Math.round(strg * 100) / 100;
        number = number.toString(10).split(".");
        var a = number[0];
        if (a.length > 12)
            return "数值超出范围！";
        var e = "零壹贰叁肆伍陆柒捌玖";
        var num1 = "";
        var len = a.length - 1;
        for (var i = 0; i <= len; i++)
            num1 += e.charAt(parseInt(a.charAt(i))) + [["圆", "万", "亿"][Math.floor((len - i) / 4)], "拾", "佰", "仟"][(len - i) % 4];
        if (number.length == 2 && number[1] != "") {
            var a = number[1]; for (var i = 0; i < a.length; i++)
                num1 += e.charAt(parseInt(a.charAt(i))) + ["角", "分"][i];
        }
        num1 = num1.replace(/零佰|零拾|零仟|零角/g, "零");
        num1 = num1.replace(/零{2,}/g, "零");
        num1 = num1.replace(/零(?=圆|万|亿)/g, "");
        num1 = num1.replace(/亿万/, "亿");
        num1 = num1.replace(/^圆零?/, "");
        if (num1 != "" && !/分$/.test(num1))
            num1 += "整";
        return num1;
    }
</script>

2.页面控件

<table>
<tr>
        <td class="EditBox_TD" width="15%">经费概算<font class="red">*</font></td>
        <td class="EditBox_TD1" width="35%">
            <asp:TextBox ID="txtFundingEstimates" runat="server" Width="80%" data-options="required:true,validType:'money'"></asp:TextBox>元</td>
        <td class="EditBox_TD" width="15%">大写</td>
        <td class="EditBox_TD1" width="35%">
            <asp:TextBox ID="txtFundingEstimatesUpper" runat="server" Width="80%" ReadOnly="true"></asp:TextBox>
        </td>
    </tr>
</table>
