本文介绍了如何使用JavaScript将数字金额转换为大写的中文格式，包括整数和小数部分，实现了金额之间的空格间隔。文章针对split(".")处理小数部分的问题进行了探讨，并提供了改进的代码示例。

 var rmbAmount = 356.400;
 var rmbAmount_ZH = "";//大写金额
 //分离整数位与小数位
 var rmbAmountArr = rmbAmount.toString().split(".");
 var inter = rmbAmountArr[0].split("");
 var decimal = rmbAmountArr[1].split("");
 //汉字的数字及单位
 var cnNums = new Array('零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖');
 var cnIntRadice = new Array('仟','佰','拾','万','仟','佰','拾','圆');
 var cnDecUnits = new Array('角','分','厘');
 //金额单位数组下标基准
 var benchmark = cnIntRadice.length - inter.length;
 //整数部分金额大写
 for(var i = 0; i < inter.length; i++){
	 rmbAmount_ZH = rmbAmount_ZH + cnNums[inter[i]] + " ";//金额
	 rmbAmount_ZH = rmbAmount_ZH + cnIntRadice[benchmark+i] + " ";//金额单位 
 }
 //小数部分金额大写
 for(var i = 0; i < decimal.length; i++){
     rmbAmount_ZH = rmbAmount_ZH + cnNums[decimal[i]] + " ";//金额
     rmbAmount_ZH = rmbAmount_ZH + cnDecUnits[i] + " ";//金额单位 
 }

最终效果就是金额大写，且间隔一个空格，下图为新建html中script中复制该代码的alert，原有运行环境是有“零分零厘”的，问题出在split(".")上，暂不处理
在这里插入图片描述
改进版***

			vm.amountTotal = amountTotal;
//			$("#amountTotal").html = amountTotal;
