Question

我需要在特定字符串之后和之前进行某些替换。示例：我需要＆＃34;用良好的字段替换错误＆＃34; MytextField＆＃34;＆＃34;。但是这个替换应该在begin {document}之后和end {document}之前完成。在开始{document}之前和结束{document}之后，没有任何单词替换。这怎么可能？。如果我使用这个代码＆＃34;用good in field＆＃34; MytextField＆＃34;＆＃34;所有坏的时刻都应该被取而代之。我不需要改变整个领域。

Answer 1

如果您的开始和结束标记只在字段中显示一次，那么这应该有效...

   put wordOffset("begin{document}",fld "MytextField") into tBegin
   put wordOffset("end{document}",fld "MytextField") into tEnd
   put replaceText(word tBegin to tEnd of fld "MytextField","bad","good") into word tBegin to tEnd of fld "MytextField"

如果标记出现多次，则需要重复循环来逐步执行每个标记。

将它放入一个字段：aa aa aa aa aa aa aa aa aa aa aa aa aa aa

将其放入按钮

local latest
    on mouseUp
       put 0 into latest
       startFinding fld 1,0
    end mouseUp

on startFinding tText,tOffset
   if the optionKey is down then exit to top --just in case...
   put wordOffset("red",fld 1,tOffset) into latest
   answer "Change word" && (latest + tOffset) && "?" with "Change" or   "Continue"
   If it = "change" then put "green" into word (latest + tOffset) of fld 1
    add latest to tOffset
    if tOffset < the number of words of fld 1 then startFinding fld 1,tOffset
end startFinding
