<c:set>

You can assign a property value to a domain where the Value property supports an El expression and can also assign a value to a JavaBean property in a domain object, both target and value support El expressions

<c:set target= "${requestscope.cust}" property= "id" value= "${param.id}" ></c:set>

<c:remove>

Removes the specified attribute from the specified domain object

<c:remove var= "Date" scope= "Session"/>

Process Control

<c:if>

There's no else, but it's OK to store the results for later use.

<c:set value= "var=" "age" scope = "Request"/>

<c:if test = "&{param.age>18}" var= "Isadult" scope= "Request"/>

Isadult: <c:out value= "${requestscope.isadult}"/> at this time the output is true

Iterative operations

<c:forEach>

See http://www.cnblogs.com/wlc297984368/p/5431638.html

${status.first} is not the first one

${status.last} is not the last one

${status.index} index starting from 0

${status.count} count starting from 1

<c:forToken>

Split () method similar to string

<c:set value= "A,B,S:F:G:G.D" var= "test" scope= "request" ></c:set>

<c:fortokens items= "${requestscope.test}" delims= "," var= "s" >&{s}<br>

</c:forTokens>

The output result is

A

B

S:f:g:g.d

<c:import>

Can contain any page to the current page

<c:import url= "http://www.baidu.com" ><c:import>

<c:redirect> page Redirection

<c:redirect url= "/test.jsp" ></c:redirect> slash represents the root of the current Web application (given to the servlet container parsing tomcat), and the browser parses the site root directory

<c:url>

Generates a URL address that encodes parameters for a GET request based on whether the cookie can be used intelligently for URL rewriting

<c:url value= "/test.jsp" var= "Testurl" >

<c:param name= "name" value= "WLC" ></c:param> transcoding if name's value is Chinese

Url:${testurl},

Result: URL:/VIP/INDEX.JSP;JSESSIONID=4F5003EEC6CCBCD87262E10B44ADEC52?NAME=WLC

Result: URL:/vip/index.jsp? Name=%e7%8e%8b%e8%bf%9e%e8%87%a3
