javascript - 在脚本中添加CSS，这可能吗？

Question

我有这个网站上的一个人帮我修复的脚本。

这是代码的第一部分，您可以在其中按标签选择和分隔博客文章。

是否可以在代码的第一部分添加 CSS，我们有标签 Terror、Shounen、Ação 并使每个标签具有不同的颜色？

例如:恐怖:蓝色 - 少年:黄色 - Ação:绿色

这个脚本通过标签拉取博主的内容，但是所有的列都是相同的颜色，我想在每个列中添加一个 css 来区分它们。

<div id="feed-list-container"></div>
<div style="clear:both;"></div>

<script type="text/javascript">
var multiFeed = {
    feedsUri: [
        {
            name: "Judul Widget 1",
            url: "https://elfenliedbrazil.blogspot.com/",
            tag: "Terror"
        },
        {
            name: "Judul Widget 2",
            url: "https://elfenliedbrazil.blogspot.com/",
            tag: "Shounen"
        },
        {
            name: "Judul Widget 1",
            url: "https://elfenliedbrazil.blogspot.com/",
            tag: "Ação"
        }
    ],
    numPost: 3,
    showThumbnail: true,
    showSummary: true,
    summaryLength: 80,
    titleLength: "auto",
    thumbSize: 200,
    containerId: "feed-list-container",
    readMore: {
        text: "Selengkapnya",
        endParam: "?max-results=20"
    }
};
</script>

This is the second part of the code.

<script>

    n, k, m, g;

    for(var e = 0, b = p[f].link.length; e < b; e++) {

Answer 1

扩展我的评论:

Might be worthwhile to explore using data attributes. Though you could also add a color code attribute to your json, and at a.innerHTML in your javascript section have it do inline css/set the background-color for the div.

但请务必注意，您的问题可能有很多解决方案，这就是我的做法。

您的 css 文件可能如下所示:

div[data-tag='Terror'] {
    background-color: blue;
}
div[data-tag='Shounen'] {
    background-color: yellow;
}
div[data-tag='Ação'] {
    background-color: green;
}

并且您将更新您的 javascript 以在您感兴趣的 html 元素上包含 data-tag="'+c.feedsUri[c.current].tag+'"。

anchor 标记可能不在您想要的位置，但这至少可以让您朝着我认为您尝试去的方向开始。

a.innerHTML = '<div data-tag="'+c.feedsUri[c.current].tag+'" +class="main-title"><h4>' + c.feedsUri[c.current].name + "</h4></div>" + d;
