1.
Jstl用法:
所需jar包:jstl*.jar
头部引入:<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
代码:
<c:choose > <c:when test="${mapEl.agstatus == '布控待确认'}"> </c:when> <c:otherwise> </c:otherwise> </c:choose>
2.
关闭:window.close().
3.
request.getAttribute()获取的值是由request.setAttribute()设置的,并且要类型转换;
request.getParameter()获取的是请求中?ggg&hhh中的参数,不需要类型转换。
4.
相互库之间的数据导入:
insert into
mydatabase.mytable(xxx,yyyy,zzzz) select * from otherdatabase.othertable;
执行后之后再commit
5.
判断是否被选中:document.getElementById("outer").checked!=true
document.all("selAll").checked = true;等价于 document.all.selAll.checked
6.
js设置固定格式的日期字符串:
js获取 var now = new Date(); var oneMonthAgo = new Date(now.setMonth(now.getMonth()-1)); //year var datestr = oneMonthAgo.getFullYear(); //month temp = oneMonthAgo.getMonth()+1; if(temp<10) { datestr+= "-0"+temp; } else { datestr+= "-"+temp; } //day temp = oneMonthAgo.getDate(); if(temp<10) { datestr+= "-0"+temp; } else { datestr+= "-"+temp; }
