Example Scripts
Example json data:
//this demo script parse the json data
sailjson json, ljson
string ls_json, ls
ls_json = ‘{“version”:”1001″,”header”:{“count”:3,”comment”:”itemscount”},”data”:[{“colid”:1,”colname”:”aaaaaa”,”coladdr”:””},{“colid”:2,”colname”:”bbbbbbbb”,”coladdr”:null},{“colid”:3,”colname”:”cccccc”}],”creattime”:”20150213.084829″}‘
json = create sailjson
json.parse( ls_json )
//get version
ls = json.getattribute( ‘version‘)
//get header, header is an object in json data
ljson = json.getattribute(‘header‘)
ls = string(ljson.getattribute(‘count‘))
ls = ljson.getattribute(‘comment‘)
integer i,li_count
any larray[]
//get data, data is array of objects
li_count = json.getarray( ‘data‘, larray)
for i = 1 to li_count
ljson = larray[i]
ls = string(ljson.getattribute( ‘colid‘))
ls = ljson.getattribute( ‘colname‘)
if isnull(ljson.getattribute( ‘coladdr‘) ) then
ls = ‘null‘
else
ls = ljson.getattribute( ‘coladdr‘)
end if
next
ls = json.getattribute( ‘createtime’)
//to display json format in treeview
integer handle
handle = tv_1.insertitemfirst(0, ‘root’, 2)
json.buildtree( tv_1, handle, 2,3,1)
tv_1.expanditem( handle)
destroy json
