Question

我正在使用DSL，并尝试自定义webEditor。当使用“ Ctrl +空格”手动调用时，使用编辑器和自动补全功能一样好。现在，如果在任何键入之后都调用提示，将很方便。我在这里找到了几种可能的解决方案。不幸的是，没有显示弹出窗口（但显示了日志消息）。

这是我的代码：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta http-equiv="Content-Language" content="en-us">
<title>Example Web Editor</title>

<link rel="stylesheet" type="text/css" href="webjars/codemirror/5.41.0/lib/codemirror.css" />
<link rel="stylesheet" type="text/css" href="xtext/2.17.0/xtext-codemirror.css" />
<link rel="stylesheet" type="text/css" href="webjars/codemirror/5.41.0/addon/hint/show-hint.css" />

<script type="text/javascript" src="webjars/codemirror/5.41.0/lib/codemirror.js"></script>
<script type="text/javascript" src="webjars/codemirror/5.41.0/addon/hint/show-hint.js"></script>
<script src="webjars/requirejs/2.3.6/require.min.js"></script>

<script type="text/javascript"> 
    var baseUrl = window.location.pathname;
    var fileIndex = baseUrl.indexOf("index.html");
    if (fileIndex > 0)
        baseUrl = baseUrl.slice(0, fileIndex)
    require.config({
        baseUrl : baseUrl,
        paths : {
            "jquery" : "webjars/jquery/3.3.1-1/jquery.min",
            "xtext/xtext-codemirror" : "xtext/2.17.0/xtext-codemirror"
        },
        packages : [ {
            name : "codemirror",
            location : "webjars/codemirror/5.41.0",
            main : "lib/codemirror"
        } ]
    });

    require([ "xtext/xtext-codemirror" ], function(xtext) {
        var editor = xtext.createEditor();

        editor.on('inputRead', function onChange(editor, input) {
            console.log("hey");
            CodeMirror.commands.autocomplete(editor);
        });
    });
</script>


</head>
<body>
    <div class="content">
        <div id="xtext-editor" data-editor-xtext-lang="adv"></div>
    </div>
</body>
</html>

这里没有任何幻想，我只是尝试在进行任何键盘输入后获得自动完成功能。

Answer 1

就像@Christian Dietrich所建议的那样，我尝试了默认项目（进行了一些修改以显示可能的自动完成列表）。不幸的是，这导致了相同的结果。通过“ Ctrl +空格”调用自动完成功能会显示可能的自动完成功能的正确列表，但键入任何内容只会创建日志消息。

第一张图片显示自动完成功能有效：intended result。第二个显示键入任何内容时的日志消息：actual result。

Codemirror和Xtext-自动补全弹出窗口不显示
