Actionscript 3 如何在不丢失Flex格式的情况下替换RichTextEditor文本

在我的ActionScript代码中，我使用richTextEditor执行以下操作

protected function createEmailTemplateContent(subRecord:String = null):void{
var index:int = emailTemplateContent.selection.beginIndex;
if(subRecord != null){
    emailTemplateContent.text = emailTemplateContent.text.substring(0,index) + '{[' + fieldTypeDD.selectedItem + '].[' + insertFieldDD.selectedItem.toString().substring(0,insertFieldDD.selectedItem.toString().indexOf('(+)')-1) +  '].[' + subRecord + ']}' + emailTemplateContent.text.substring(index,emailTemplateContent.text.length);
}else{
    emailTemplateContent.text = emailTemplateContent.text.substring(0,index) + '{[' + fieldTypeDD.selectedItem + '].[' + insertFieldDD.selectedItem + ']}' + emailTemplateContent.text.substring(index,emailTemplateContent.text.length);
}
}

<component:RichTextEditorWithAllControls id="emailTemplateContent" dropShadowVisible="false" creationComplete="emailTemplatesContentInit()" headerHeight="0" width="100%" height="100%" htmlText="@{emailTemplateObject.emailContent}" showControlBar="false" verticalScrollPolicy="auto"/>

当用户从下拉列表中选择项目时，将实现上述方法。然后，该特定项将填充在富文本编辑器的文本区域内

我的问题是，如果用户已经对文本进行了一些格式化（使用RichTextEditor中的格式化选项），那么当用户选择一个项目并填充文本区域时，这些内容也会被替换

在这里，“emailTemplateContent”是指RichTextEditor。我已将RichTextEditor代码包含在以下内容中

protected function createEmailTemplateContent(subRecord:String = null):void{
var index:int = emailTemplateContent.selection.beginIndex;
if(subRecord != null){
    emailTemplateContent.text = emailTemplateContent.text.substring(0,index) + '{[' + fieldTypeDD.selectedItem + '].[' + insertFieldDD.selectedItem.toString().substring(0,insertFieldDD.selectedItem.toString().indexOf('(+)')-1) +  '].[' + subRecord + ']}' + emailTemplateContent.text.substring(index,emailTemplateContent.text.length);
}else{
    emailTemplateContent.text = emailTemplateContent.text.substring(0,index) + '{[' + fieldTypeDD.selectedItem + '].[' + insertFieldDD.selectedItem + ']}' + emailTemplateContent.text.substring(index,emailTemplateContent.text.length);
}
}

<component:RichTextEditorWithAllControls id="emailTemplateContent" dropShadowVisible="false" creationComplete="emailTemplatesContentInit()" headerHeight="0" width="100%" height="100%" htmlText="@{emailTemplateObject.emailContent}" showControlBar="false" verticalScrollPolicy="auto"/>

我假设发生这种情况是因为当我在richTextEditor中填充“text”值时，“htmlText”值也会被替换

有人知道克服这个问题的方法吗

提前感谢。

首先将连接的文本存储在字符串中，然后将其替换为html文本。像下面这样

protected function createEmailTemplateContent(subRecord:String = null):void{
  var index:int = emailTemplateContent.selection.beginIndex;
  var newText:String;
  if(subRecord != null){
    newText = emailTemplateContent.text.substring(0,index) 
    + '{[' + fieldTypeDD.selectedItem + '].[' + insertFieldDD.selectedItem.toString().substring(0,insertFieldDD.selectedItem.toString().indexOf('(+)')-1) +  '].[' + subRecord + ']}' + emailTemplateContent.text.substring(index,emailTemplateContent.text.length);
  }else{
    newText = emailTemplateContent.text.substring(0,index) + '{[' + fieldTypeDD.selectedItem + '].[' + insertFieldDD.selectedItem + ']}' + emailTemplateContent.text.substring(index,emailTemplateContent.text.length);
  }
  emailTemplateContent.htmlText = emailTemplateContent.htmlText.replace(emailTemplateContent.text, newText);
}

您是否可以添加显示格式化文本的屏幕截图，以及从下拉列表中选择项目后会发生什么情况？
