Re: How we read the list<map;string>

Hi Yadid,

You can use is_hash_ex to find if the item is a map

Subject: [FreeMarker-user] How we read the list

Hello Freemarker Team,

There is one issue it confused me.

Eg: java code:

SimpleHash root = new SimpleHash();

List<Object> list =
new ArrayList<Object>();

list.add("red");

list.add("green");

list.add("blue");

SimpleHash mapColor =
new SimpleHash();

mapColor.put("c1",
"red");

mapColor.put("c2",
"green");

mapColor.put("c3",
"blue");

list.add(mapColor);

root.put("theList", list);

FTL file:

<#list theList as item>

<#if item_index =3> à
if I do not know the index=3, then how I read the map in the list.

<#assign keys = item?keys>

<#list keys as key>

${key} = ${item[key]}<br>

</#list>

<#else>

${item_index + 1}. ${item}<br>

</#if>

</#list>

Output:

+- theList

| |

+- 1. red

| |

+- 2. green

| |

+- 3. blue

| |

||

+- c1 = red

||

+- c2 = green

||

+- c3 = blue

Thanks & Best Regards,

Yadid
