问题：怎样修改资金余额小数位数
解决：后台管理 >> 系统设置 >> 模板标签管理 >> 标签管理，找到并修改标签“Ajax用户登录”，找到下面段代码：
|
function GetUserInfo(xml)
{
var userInfo="<div class=\"u_login\">" xml.getElementsByTagName("username")[0].firstChild.data "，您好！您有：<br/>";
userInfo =userInfo "资金余额：" xml.getElementsByTagName("balance")[0].firstChild.data " 元<br/>";
userInfo =userInfo "经验积分：" xml.getElementsByTagName("exp")[0].firstChild.data " 分<br/>";
userInfo =userInfo "待阅短信：" xml.getElementsByTagName("msg")[0].firstChild.data " 条<br/>";
userInfo =userInfo "登录次数：" xml.getElementsByTagName("logintimes")[0].firstChild.data " 次<br/>";
userInfo =userInfo "可用点券：" xml.getElementsByTagName("point")[0].firstChild.data " " xml.getElementsByTagName("pointunit")[0].firstChild.data "<br/>";
userInfo =userInfo "待签文章：" xml.getElementsByTagName("signincontent")[0].firstChild.data " 篇<br/>";
userInfo =userInfo "<div style=\"text-align: center\"><a href=\"{PE.SiteConfig.ApplicationPath /}User/Default.aspx\" target=\"_top\">会员中心</a> | ";
userInfo =userInfo "<a href=\"{PE.SiteConfig.ApplicationPath /}User/Logout.aspx\" target=\"_top\">退出登录</a></div>";
userInfo=userInfo "</div>";
return userInfo;
} |
改为：
|
function GetUserInfo(xml)
{
var userInfo="<div class=\"u_login\">" xml.getElementsByTagName("username")[0].firstChild.data "，您好！您有：<br/>";
userInfo =userInfo "资金余额：" xml.getElementsByTagName("balance")[0].firstChild.data " 元<br/>";
userInfo =userInfo "资金余额：" round(xml.getElementsByTagName("balance")[0].firstChild.data,2) " 元<br/>";
userInfo =userInfo "经验积分：" xml.getElementsByTagName("exp")[0].firstChild.data " 分<br/>";
userInfo =userInfo "待阅短信：" xml.getElementsByTagName("msg")[0].firstChild.data " 条<br/>";
userInfo =userInfo "登录次数：" xml.getElementsByTagName("logintimes")[0].firstChild.data " 次<br/>";
userInfo =userInfo "可用点券：" xml.getElementsByTagName("point")[0].firstChild.data " " xml.getElementsByTagName("pointunit")[0].firstChild.data "<br/>";
userInfo =userInfo "待签文章：" xml.getElementsByTagName("signincontent")[0].firstChild.data " 篇<br/>";
userInfo =userInfo "<div style=\"text-align: center\"><a href=\"{PE.SiteConfig.ApplicationPath /}User/Default.aspx\" target=\"_top\">会员中心</a> | ";
userInfo =userInfo "<a href=\"{PE.SiteConfig.ApplicationPath /}User/Logout.aspx\" target=\"_top\">退出登录</a></div>";
userInfo=userInfo "</div>";
return userInfo;
}
function round(v,e)
{
var t=1;
for(;e>0;t*=10,e--);
for(;e<0;t/=10,e );
return Math.round(v*t)/t;
} |
修改下面的“2”，可以实现位数控制，0为无小数位，1为一位小数，2为二位小数，3为三位小数。

userInfo =userInfo "资金余额：" round(xml.getElementsByTagName("balance")[0].firstChild.data,2) " 元<br/>";
