之前几乎没有JavaScript,但我尝试了几种方法将尖号(结束)放置在JavaFX HTMLEditor中,但没有成功。

例如,我已经尝试过:contenteditable, set caret at the end of the text (cross-browser)通过在placeCaretAtEnd(el)部分中添加函数<script>,如下所示(我在这里省略了<script>部分):

<html>
<head>
<style>
</style>
</head>
<body onLoad='document.body.focus();' onfocus='placeCaretAtEnd(document.body);' contenteditable='true'>
</body>
</html>


(我通过HTMLEditor.setHtmlText进行了设置)

但是,插入符号始终停留在开头。是否有人成功将插入符号放置在JavaFX HTMLEditor中?

最佳答案

好吧,我终于开始工作了。我不确定onfocus为什么不起作用。

public void requestFocus() {
        HTMLEditorSkin skin = (HTMLEditorSkin) editor.getSkin();
        try {
            Field f = skin.getClass().getDeclaredField("webView");
            f.setAccessible(true);
            WebView wv = (WebView) f.get(skin);
            Platform.runLater(() -> {
                wv.requestFocus();
                wv.getEngine().executeScript("document.body.focus()");
                wv.getEngine().executeScript(
                                "var el = document.body;\n" +
                                "if (typeof window.getSelection != \"undefined\"\n" +
                                "            && typeof document.createRange != \"undefined\") {\n" +
                                "        var range = document.createRange();\n" +
                                "        range.selectNodeContents(el);\n" +
                                "        range.collapse(false);\n" +
                                "        var sel = window.getSelection();\n" +
                                "        sel.removeAllRanges();\n" +
                                "        sel.addRange(range);\n" +
                                "    } else if (typeof document.body.createTextRange != \"undefined\") {\n" +
                                "        var textRange = document.body.createTextRange();\n" +
                                "        textRange.moveToElementText(el);\n" +
                                "        textRange.collapse(false);\n" +
                                "        textRange.select();\n" +
                                "    }");
            });
        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }
