Answer 1

我决定的解决方案很简单，我添加了一个类来了解我当前正在编辑的是哪一段文本，然后将颜色 CSS 属性设置为颜色选择器对该所选类的选择。

所以你的 onclick 现在是:

var onclick = 'onclick="editTextColour(this)"';

我创建了一个新函数来处理基础知识，(this) 因为 onclick 的参数被视为调用它的元素:

function editTextColour(elem) {
    $('.editing').removeClass('editing');
    $(elem).addClass('editing');
    $('.edit-block').show();
}

然后颜色选择器的更改事件就是这样:

$(".color").on("change", function() {
    var colorValue = $(".color").val();
    $('.preview .editing').css('color', colorValue);
});
