按关键字或类检查相关复选框？

问题描述 投票：1回答：1

我有许多无序项目放在其他文件夹中（通过Web进行文件管理）每个元素都有一个名称和格式，每个格式都有一个类。 截图： Screenshot

在这里，我们看到文件是如何呈现的，正如我之前提到的，它们有一个名称和格式。还可以看到每种格式都显示有不同的类，音频类型，文本类型，平板电脑等。

HTML：

脚本如何运行所有文件，参与文本并检查它？

例如，如果我想选择包含关键字“MacOS”的所有元素，则选择包含“MacOS”一词或其格式的所有元素。我没有在扩展或用户脚本中看到过类似的内容。

你能创造出类似的东西吗？

如果你不能创造这样的东西，那么我猜你可以拿你的'课'并自动选择所有匹配的？

总结：脚本如何仅标记'.rar'文件，例如，在所有其他文件中？

首先标识指示所需文件的节点。对于.rar文件，它将像：

var zipFiles = document.querySelectorAll (".fileItemContainer > .filename.zip");

如果你真的只想要.rar而不是其他类型的压缩文件，那么：

zipFiles = Array.from (zipFiles).filter (node => /\.rar\b/i.test (node.querySelector (".downloadContext").textContent) );

然后，遍历DOM到相关的复选框：

zipFiles.forEach (node => {
    var theChckBox = node.previousElementSibling.querySelector ("input[type='checkbox']");
} );

并检查他们：

zipFiles.forEach (node => {
    var theChckBox = node.previousElementSibling.querySelector ("input[type='checkbox']");
    theChckBox.checked = true;
} );

jQuery中的所有内容：

$(".fileItemContainer > .filename.zip").has (".downloadContext:contains(.rar)").prev ().find ("input[type='checkbox']").prop ("checked", true);

- .has(...)位是可选的。

如果页面是AJAX（javascript）驱动的，请使用waitForKeyElements或MutationObserver。

演示：

// ==UserScript==
// @name     _Check select text boxes
// @match    *://YOUR_SERVER.COM/YOUR_PATH/*
// @require  https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// @grant    GM.getValue
// ==/UserScript==
// @grant    none
//- The @grant directives are needed to restore the proper sandbox.
/* global $, waitForKeyElements */
/* eslint-disable no-multi-spaces, */

waitForKeyElements (".fileItemContainer > .filename.zip", clickRelatedCheckbox);

function clickRelatedCheckbox (jNode) {
    var theChckBox = jNode.prev ().find ("input[type='checkbox']");
    theChckBox.prop ("checked", true);
}
