[xwiki-users] Fw : Re: Need help with velocity+json (resolved) - xwiki-users@xwiki.org

28 Jul 2015

After one fastidious debuging day ;-)) , here some snippet to edit map with velocity with
put and/or velocity variable (with space character):

#set ($MyArray1={})
* $jsontool.serialize($MyArray1)
#set ($indexNiv1='Index 2')
##set ($discard=$MyArray1.put('Index2',{}))
#set ($MyArray1[$indexNiv1]={})
* $jsontool.serialize($MyArray1)
##set ($discard=$MyArray2.put('Index2',{'Field1':'Addon value'}))
#set ($field1='Field 1')
##set ($discard=$MyArray1.put($indexNiv1,{$field1:'Addon value'}))
#set ($MyArray1[$indexNiv1][$field1]='Addon value')
* $jsontool.serialize($MyArray1)
#set ($field2="Field 2")
##set ($discard=$MyArray1[$indexNiv1].put($field2,'Another value'))
#set ($MyArray1[$indexNiv1][$field2]='Another value')
* $jsontool.serialize($MyArray1)
#set ($discard=$MyArray1.put('Index 2',{'Field1':'Addon
value','field 2':'Another addon value'}))
* Values in one shot:  $jsontool.serialize($MyArray1)
$MyArray1.keySet()

 By the way, are there a
 "xwiki tricks" to pass a variable from velocity to
 javascript ?

 Anyways, this
 way working well (replace MyArray by MyMap ;-) ) :

 {{velocity}}
 {{html}}
 #set ($MyArray={

 'Index1':{'Field1':'value1','field2':'value2'},
   'Index3':{'Field1':'A
 value','field2':'Another value'}
 })
  <script
 type="text/javascript">
    var
 MaVariable=$jsontool.serialize($MyArray);

 </script>
 {{/html}}
 {{/velocity}}

 And in my XWiki.JavaScriptExtension object:

 function change_value(bouton,
 idTarget) {

 require(['jquery'], function ($) {
     // xxxxx
     var obj
 = MaVariable;

 alert(obj["Index2"]["field2"]);

     });
 };

  Thxs a lot:
  "put"
 is my new friend :-)

  Here
 the answer:
  #set

 ($MyArray={

 'Index1':{'Field1':'value1','field2':'value2'},

 'Index3':{'Field1':'A

 value','field2':'Another value'}
  })

 $MyArray.getClass().getName()
  *
  Original map

 $jsontool.serialize($MyArray)
  *
  I Modify the 'Index3' entrie:
  #set

 ($discard=$MyArray.put('Index3',{'Field1':'A
  modified
 value','field2':'Another modified
  value'}))

 $jsontool.serialize($MyArray)
  *
  I add the 'Index2' entrie:
  #set

 ($discard=$MyArray.put('Index2',{'Field1':'Addon
  value','field2':'Another
 addon
  value'}))

 $jsontool.serialize($MyArray)
