按关键字或 class 检查相关复选框？

Question

我有很多未排序的项目放在其他文件夹中（通过网络进行文件管理）每个元素都有一个名称和格式，每个格式都有一个 class。
截图：

这里我们看到文件是如何呈现的，正如我之前提到的，它们有名称和格式。还可以看出，每种格式都显示了不同的class，即音频类型、文本类型、平板电脑等

脚本如何运行遍历所有文件，提取部分文本并进行检查？

例如，如果我想select所有包含关键字的元素 'MacOS'，然后是 select 所有包含单词 'MacOS' 或者它的词的那些格式。我在扩展程序或用户脚本中都没有看到这样的东西。

你能创造出类似的东西吗？

如果你不能创建类似的东西，那么我想你可以使用你的 'class' 并自动 select 所有匹配的？

总结：脚本如何只标记'.rar'文件，例如，在所有其他文件中？

DEMO on JSFiddle

Answer 1

首先确定指示您想要的文件的节点。对于 .rar 个文件，它就像：

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

如果您真的只想要 .rar 而不需要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']");
} );

然后检查它们：

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

在jQuery中的所有内容：

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

-- 其中 .has(...) 位是可选的。

如果页面由 AJAX (javascript) 驱动，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);
}
