當您找到匹配值時,將它們存儲在臨時表中,例如, table.insert(temporaryTable, value)
而不是使用return
退出功能。您可以在下面找到一個示例函數,該函數收集並計算多維表格內的變量中查詢字符串的出現次數(或者在動作here中查看它)。
--data

function countStringOccurence(query, itemList)
query = string.lower(query)
--if query string is found, store index of the itemList in table searchResult
local searchResult = {}
for i, item in ipairs(itemList) do
local name = string.lower(item.name)
if string.find(name, query) then
table.insert(searchResult, i)
end
end
--return both the occurence count and the list of found item
return #searchResult, searchResult
end
--execute the function
count, foundItemList = countStringOccurence("thomas", itemList)
--print results
print(count) --> 2
for i, index in ipairs(foundItemList) do
print(index, itemList[index].name) --> 4 Thomas Hemming
--> 26 Thomas Brenner
end
注:請注意,如果你的表/列表條目可能圍繞移動(例如sort
),它可能不是最好只儲存數組索引,因爲在foundItemList
收集的引用/值可能會不正確。
