問題：怎樣修改資金余額小數位數
解決：后臺管理 >> 系統設置 >> 模板標簽管理 >> 標簽管理，找到并修改標簽“Ajax用戶登錄”，找到下面段代碼：
|
function GetUserInfo(xml)
{
var userInfo="<div class=\"u_login\">" xml.getElementsByTagName("username")[0].firstChild.data "，您好！您有：<br/>";
userInfo =userInfo "資金余額：" xml.getElementsByTagName("balance")[0].firstChild.data " 元<br/>";
userInfo =userInfo "經驗積分：" xml.getElementsByTagName("exp")[0].firstChild.data " 分<br/>";
userInfo =userInfo "待閱短信：" xml.getElementsByTagName("msg")[0].firstChild.data " 條<br/>";
userInfo =userInfo "登錄次數：" xml.getElementsByTagName("logintimes")[0].firstChild.data " 次<br/>";
userInfo =userInfo "可用點券：" xml.getElementsByTagName("point")[0].firstChild.data " " xml.getElementsByTagName("pointunit")[0].firstChild.data "<br/>";
userInfo =userInfo "待簽文章：" 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\">會員中心</a> | ";
userInfo =userInfo "<a href=\"{PE.SiteConfig.ApplicationPath /}User/Logout.aspx\" target=\"_top\">退出登錄</a></div>";
userInfo=userInfo "</div>";
return userInfo;
} |
改為：
|
function GetUserInfo(xml)
{
var userInfo="<div class=\"u_login\">" xml.getElementsByTagName("username")[0].firstChild.data "，您好！您有：<br/>";
userInfo =userInfo "資金余額：" xml.getElementsByTagName("balance")[0].firstChild.data " 元<br/>";
userInfo =userInfo "資金余額：" round(xml.getElementsByTagName("balance")[0].firstChild.data,2) " 元<br/>";
userInfo =userInfo "經驗積分：" xml.getElementsByTagName("exp")[0].firstChild.data " 分<br/>";
userInfo =userInfo "待閱短信：" xml.getElementsByTagName("msg")[0].firstChild.data " 條<br/>";
userInfo =userInfo "登錄次數：" xml.getElementsByTagName("logintimes")[0].firstChild.data " 次<br/>";
userInfo =userInfo "可用點券：" xml.getElementsByTagName("point")[0].firstChild.data " " xml.getElementsByTagName("pointunit")[0].firstChild.data "<br/>";
userInfo =userInfo "待簽文章：" 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\">會員中心</a> | ";
userInfo =userInfo "<a href=\"{PE.SiteConfig.ApplicationPath /}User/Logout.aspx\" target=\"_top\">退出登錄</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”，可以實現位數控制，0為無小數位，1為一位小數，2為二位小數，3為三位小數。
|
userInfo =userInfo "資金余額：" round(xml.getElementsByTagName("balance")[0].firstChild.data,2) " 元<br/>";
