JEdi​​torPane中的可点击HTML链接但是使用replaceSelcetion方法 [英] Clickable HTML link in JEditorPane But using replaceSelcetion methode

问题描述

我搜索了如何在 JEditorPane 中制作可点击链接，我发现此问题

I searched of how to make clickable links in JEditorPane and i found this Question

是否可以用Java创建程序以创建要在Chrome中链接的文本？

这是非常有用但我的代码使用重复声明

It was very useful but my code use a Repetition Statement

JEditorPane jep = new JEditorPane();
jep.setContentType("text/html");
jep.setEditable(true);// Because .replaceSelection can't work with disabled edit
for ( int i = 1; i <= 3; i++ ){
    jep.replaceSelection(
        "Welcome to <a href='https://stackoverflow.com/'>StackOverflow i </a>.");
}
jep.setEditable(false);

现在它只显示没有可点击链接的文字，所以我将如何做到正确我真的需要 replaceSelection 方法

And now it show me just text without clickable links so how I'm going to make it right and I really need replaceSelection method

推荐答案

使用 HTMLDocument 上的replaceSelection（）插入原始字符串;您想要插入HTML锚标记。你可以，

Using replaceSelection() on an HTMLDocument inserts the raw string; you want to insert an HTML anchor tag. You can,

• 自己管理原始HTML文本，如下所示，并让 setText（） 处理解析。

使用现有的 HTMLEditorKit 嵌套操作。

Use one of the existing HTMLEditorKit nested actions.

使用此处中的一种自定义方法。

Use one of the custom approaches seen here.
