For Loop tag, for tag

Function: loop tag

Objects (schoolbags) can be recycled from small to large, or from large to small

If the object (schoolbag) parameter is not specified, a default cyclic object (schoolbag) is generated)

Nested loops

　　Usage:

<For bags = [schoolbag 1 | schoolbag 2 |...] [start = start value] [end = end value] [step = step value]>

<Cyclic tag>... </cyclic tag>

</For>

· Bags

· Start: start value. The default value is 0.

· End: the end value. The default value is 10.

· Step: step size. The default value is 1.

· Cyclic tags: WebEasy Language tags or html tags, which cannot be blank

chtml><for><b>@{for:getSuffix}-</b></for></chtml>

From 0 to 10, the last digit is less than 10,

Example above: A big data application example of Traffic Analysis

List name

<Ul> <li style = "width: 917px; border-top: 0px; border-left: 0px "> <B> Real-time Data </B> </li> </ul> <li style =" width: 171px; background-color: # 008B8B; "> time </li> <li style =" width: 70px; background-color: # 008B8B; "> guest </li> <li style =" width: 120px; background-color: # 008B8B; "> ip </li> <li style =" width: 280px; background-color: # 008B8B; "> from </li> <li style =" width: 280px; background-color: # 008B8B; border-right: 1px # B4B4B4 solid; "> access address </li> </ul>

Query real-time traffic records (vertica database)

<esql module=vertica id=list>select ts,uid,client_ip,case when ref_protocol='' then '' else ref_protocol||'://'||ref_host||ref_uri || (case when ref_para='' then '' else '?' || ref_para end) end as ref,case when page_protocol='' then '' else page_protocol||'://'||page_host||page_uri||(case when page_para='' then '' else '?'||page_para end) end as page from roi.visit_log @{pPage:where} order by ts desc limit 100;</esql>

Use For tag LoopOutput custom list (Note: bags = list)

<For bags = list end = "@ {list: getLength}"> <ul> <li style = "width: 171px" >@{ intLeft :@{ list: ts} (19)} </li> <li style = "width: 70px" >@{ list: uid} </li> <li style = "width: 120px ">@{ list: client_ip} </li> <if x =" {list: ref} "else = 1> <li style =" width: 280px "> direct access </li> <li style =" width: 280px "> <a href =" @ {list: ref} "target = _ blank >@{ intleft: @ {list: ref} (30) }</a> </li> </if> <li style = "width: 280px; border-right: 1px # B4B4B4 solid; "> <a href =" @ {list: page} "target = _ blank >@{ intleft :@{ list: page} (30 )} </a> </li> </ul> </for>
