Question

我正在制作简单的编辑器。我想要的是，当我写任何文本时，让我们写一下将无色文本替换为RichEditableText中的彩色文本。

例如： PHP - ＆gt; <s:span color="#FF0000">PHP<s:span>

此代码不起作用：

editorum.text = editorum.text.replace('PHP','<s:span color="#FF0000">php<s:span>');

Editorum是：<s:RichEditableText id="editorum" ></s:RichEditableText>

        <!-- Place non-visual elements (e.g., services, value objects) here -->

    <fx:Script>

            import spark.events.TextOperationEvent;
            import spark.utils.TextFlowUtil;
            protected function editorum_changeHandler(event:TextOperationEvent):void
            {
                editorum.text = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>');
            }
        ]]>
    </fx:Script>
    <s:RichEditableText id="editorum" x="10" y="28" width="299" height="159"
                        change="editorum_changeHandler(event)">

    </s:RichEditableText>
    <s:Label x="10" y="10" width="119" text="Write 'melon' :"/>
</s:Application>

另一个问题;如何在结尾发送指针？当我按任意键时，指针就会处理。尝试：http://samed.us/samples/ops3.swf

感谢您的帮助......

Answer 1

而不是这一行：

editorum.text = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>');

尝试这样的事情：

var text : String = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>')
editorum.textFlow = TextConverter.importToFlow(text, TextConverter.TEXT_FIELD_HTML_FORMAT);

基本上，您需要将HTML转换为TLF Framework将理解的内容。 textFlow上的Read some docs和TextConverter
