插入位置到JEditorPane的html中 [英] caret position into the html of JEditorPane

问题描述

JEditorPane的getCaretPosition方法仅为html控件的文本部分提供索引。是否有可能将索引放入html文本？

The getCaretPosition method of JEditorPane gives an index into the text only part of the html control. Is there a possibility to get the index into the html text?

更具体地说，假设我有一个html文本（其中|表示插入位置）

To be more specific suppose I have a html text (where | denotes the caret position)

abcd<img src="1.jpg"/>123|<img src="2.jpg"/>

现在getCaretPosition给出8而我需要25才能读出图像的文件名。

Now getCaretPosition gives 8 while I would need 25 as a result to read out the filename of the image.

推荐答案

我认为您不能将您的插入符号转换为能够将标记计为字符。如果你的最终目的是读取图像文件名，你应该使用：

I don't think you can transform your caret to be able to count tags as characters. If your final aim is to read image filename, you should use :

HTMLEditorKit (JEditorPane.getEditorKitForContentType("text/html") );
