翻译下面这段代码const options = this.$el.querySelector( ".el-picker-panel__body .el-picker-panel__content" ); this.dates.forEach((date) => { const option = options.querySelector( `td.available:not(.disabled) div[title="${date}"]` ); if (option) { option.style.position = "relative"; option.style.paddingRight = "12px"; // 防止圆点被遮挡 const dot = document.createElement("span"); dot.style.display = "block"; dot.style.position = "absolute"; dot.style.content = "' '"; dot.style.width = "6px"; dot.style.height = "6px"; dot.style.borderRadius = "50%"; dot.style.backgroundColor = "blue"; dot.style.left = "calc(100% - 10px)"; dot.style.top = "50%"; dot.style.transform = "translateY(-50%)"; option.appendChild(dot); } });

这段代码的功能是在日期选择器中的指定日期单元格上添加一个蓝色的圆点。以下是代码的翻译：

const options = this.$el.querySelector(".el-picker-panel__body .el-picker-panel__content");
// 找到日期选择器中所有日期单元格的父元素

this.dates.forEach((date) => {
  // 遍历需要添加圆点的日期列表

  const option = options.querySelector(`td.available:not(.disabled) div[title="${date}"]`);
  // 找到对应日期的单元格元素

  if (option) {
    // 如果单元格存在

    option.style.position = "relative";
    option.style.paddingRight = "12px"; // 防止圆点被遮挡

    const dot = document.createElement("span");
    // 创建一个 span 元素用于显示圆点

    dot.style.display = "block";
    dot.style.position = "absolute";
    dot.style.content = "' '";
    dot.style.width = "6px";
    dot.style.height = "6px";
    dot.style.borderRadius = "50%";
    dot.style.backgroundColor = "blue";
    dot.style.left = "calc(100% - 10px)";
    dot.style.top = "50%";
    dot.style.transform = "translateY(-50%)";
    // 设置 span 元素的样式

    option.appendChild(dot);
    // 将 span 元素添加到单元格中
  }
});
