如何替换 livecode 中的 html 文本

Question

我正在使用此代码用相同的单词替换一个带有删除的单词。它工作正常。

replace Str[1] with  "<strike><font bgcolor=" & quote & "yellow" & quote & ">" & Str[1] & "</font></strike>" in myHtml

但是当我更换它时，反之亦然，它不起作用。我正在使用此代码替换

replace "<strike><font bgcolor=" & quote & "yellow" & quote & ">" & Str[1] & "</font></strike>" with Str[1] in myHtml

Answer 1

你的代码对我来说确实有效。它在第一个 answer 上击中并给 "def" 上色，但在第二个上恢复正常。也许您在转义 quotes?

时遇到了一些问题

 put "abc def"  into myHtml
 put "def" into Str[1]
replace Str[1] with  "<strike><font bgcolor=" & quote & "yellow" & quote & ">" & Str[1] & "</font></strike>" in myHtml
answer myHtml -- "def" is yellow and stroke
replace "<strike><font bgcolor=" & quote & "yellow" & quote & ">" & Str[1] & "</font></strike>" with Str[1] in myHtml 
answer myHtml -- "def" is back to normal text

Answer 2

具有两个按钮和一个文本字段的工作示例：

按钮 1：

on mouseUp
put the htmlText of field "MytextField" into myHtml 
put item 1 of myhtml into str[1]
replace Str[1] with "<strike><font bgcolor=" & quote & "yellow" & quote & ">" & Str[1] & "</font></strike>" in myHtml 
set the htmlText of fld "MytextField" to myHtml
end mouseUp

按钮 2：

on mouseUp
put the htmlText of field "MytextField" into myHtml 
 put "abc" into str[1]
replace "<strike><font bgcolor=" & quote & "#FFFF00" & quote & ">" & Str[1] & "</font></strike>" with Str[1] in myHtml 
set the htmlText of fld "MytextField" to myHtml
end mouseUp

以及我如何设置文本字段

set the htmltext of field "mytextfield" to "abc,def"
