如何设置摩纳哥编辑器上下文菜单的样式

Question

我需要更改默认上下文菜单的 css 样式，但我无法检查类因为它在失焦时关闭，所以如果有人知道类或知道如何使用 javascript 调整样式会有所帮助。

Answer 1

我有类似的问题，我需要替换出现在完成菜单中的图标。

我在浏览器的“网络”选项卡中打开了文件 editor.main.css。

在那里，您可以看到 css 选择器，以及图标的嵌入式 svg-xml。

例如，要替换完成菜单中用于 'methods' 或 'functions' 的图标，请将其添加到您的 html（加载 Monaco 样式表后）

.monaco-editor .suggest-widget .monaco-list .monaco-list-row .suggest-icon.method::before,
.monaco-editor .suggest-widget .monaco-list .monaco-list-row .suggest-icon.function::before

Answer 2

按 F12 显示控制台。输入代码并按回车键。

setTimeout(() => {debugger;}, 1000);

您可以在浏览器暂停前 1 秒打开上下文菜单。然后你可以检查元素。

.monaco-menu > .monaco-action-bar.vertical {
  color: red !important;
}

但自 0.12 起，上下文菜单位于 shadow-root 下，并且没有元素声明 part 属性。所以在host里面没办法改写style

Answer 3

实际上有一种方法可以覆盖上下文菜单的样式表，因为 Shadow DOM 仍处于模式 open.

这里有一小段代码可能会对您有所帮助。

function injectMonacoContextMenuStyle(editorElement) {
  const host = editorElement.querySelector(".shadow-root-host");

  // adds the custom stylesheet once per editor
  if (host && host.shadowRoot && !host.shadowRoot.querySelector(".custom")) 
  {
    const style = document.createElement("style");

    style.setAttribute("class", "custom");
    style.innerHTML = `
      .context-view.monaco-menu-container > .monaco-scrollable-element {
        border-radius: 8px;
      }
    `;
    host.shadowRoot.prepend(style);
  }
}
 
const editor = Editor.create(element, config);
    
editor.onContextMenu(() => injectMonacoContextMenuStyle(element));
