java - How to do for each in Struts 2 -
i trying build slider web page in html. gets values arraylist(named testlist) struts action. , want display 6 values list @ time in pattern.for ex:
if array of size 26, {0,1,2,3,4,5} {6,7,8,9,10,11} {11,12,13,14,15} .. , on upto {24,25} ,rest values if null ok.
something each loops: for(i=0;i<size;i+6){}
but values list in pattern :
{0,1,2,3,4,5} {1,2,3,4,5,6} {2,3,4,5,6,7} ..
which because index(#status.index)iterates in following pattern {0,1,2,3...} want index increment 6 everytime instead of 0 1 2 etc.
i added step="6" , not working.
here sample of code below:
<ul class="slider"> <s:iterator step="6" status="status" value="testlist" > <li> <!-- first slot of data --> <div class="rightsubcontainer"> <s:iterator value="testlist[#status.index]" > <table > <tr> <th> <p align="center"><b ><font color="#151b54"><s:property value="name" /></font></b></p> </th> </tr> </table> <!-- ...values --> </s:iterator> </div> <div class="rightsubcontainer"> <s:iterator value="testlist[#status.index+1] " > <table > <tr> <th> <p align="center"><b ><font color="#151b54"><s:property value="name" /></font></b></p> </th> </tr> </table> <!-- ...values --> </s:iterator> </div> <div class="rightsubcontainer"> <s:iterator value="testlist[#status.index+2]" > <table > <tr> <th> <p align="center"><b ><font color="#151b54"><s:property value="name" /></font></b></p> </th> </tr> </table> <!-- ...values --> </s:iterator> </div> <!-- ... , on.. upto 6 values -->
why 1 table each value ? why 1337 iterators instead of single 1 ? why <b>, <font> etc instead of using css ?
by way need use % (module operator) check if current position multiple of six; if is, need split <li>;
note iteratorstatus.count same iteratorstatus.index + 1, because 1-based;
ugly way:
<ul class="slider"> <li> <s:iterator status="status" value="testlist" > <table > <tr> <th> <p align="center"><b ><font color="#151b54"> <s:property value="name" /> </font></b></p> </th> </tr> </table> <s:if test="%{#status.count % 6 == 0}" > </li> <li> </s:if> </s:iterator> </li> </ul> better way:
<ul class="slider"> <li> <s:iterator status="status" value="testlist" > <p> <s:property value="name" /> </p> <s:if test="%{#status.count % 6 == 0}" > </li> <li> </s:if> </s:iterator> </li> </ul> and in css (or inside <style></style> block in <head> element)
ul.slider > li > p { text-align: center; color: #151b54; font-weight: bold; background-color: #ddd; }
