我找到了一个 JQuery 脚本，它允许您通过单击突出显示文本中的单词。
无论如何，是否可以修改只能通过单击突出显示一个单词的代码？因此，如果用户点击第二个词，第一个颜色编码的词将恢复正常。
var words = $( "p" ).first().text().split( /\s+/ );
var text = words.join( "</span> <span>" );
$( "p" ).first().html( "<span>" + text + "</span>" );
$( "span" ).on( "click", function() {
$( this ).css( "background-color", "red" );
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

最佳答案
第一通电话$("span").css("background-color", "");重置所有颜色 <span> s 在设置被点击元素的颜色之前:
var words = $("p").first().text().split(/\s+/);
var text = words.join("</span> <span>");
$("p").first().html("<span>" + text + "</span>");
$("span").on("click", function() {
$("span").css("background-color", "");
$(this).css("background-color", "red");
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p>

</p>您还可以将点击的元素保存在变量中:
var words = $("p").first().text().split(/\s+/);
var text = words.join("</span> <span>");
$("p").first().html("<span>" + text + "</span>");
let highlighted;
$("span").on("click", function() {
$(highlighted).css("background-color", "");
$(this).css("background-color", "red");
highlighted = this;
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
