Question

我正在尝试将javascript对象文字输出到HTML表中。由于我需要遍历对象，因此我将表头的创建分为一个函数，与从对象中迭代的表行相同，最后还有一个用于构建表脚的函数。然后，一个具有三行的自我执行函数执行这三个函数来构建我的完整表。

但是，问题是页脚的内部HTML放置在表的外部（在表的后面），并且根本不生成页脚元素。我已经遍历了多次代码，并且在合并中也看不到任何语法错误。我是否在代码中或执行本身中缺少某些内容（某些我不知道的经验法则或其他内容）？我的代码：

Javascript：

    prop2: ['<span class="mainItem">Item 2</span>', 100, 'show', 'count'],
    get prop3() { //access with my_object.handledareutbildning

Answer 1

通过仅合并topRow()和sumRow()函数，而是使用由tableElement()和{中的两个字符串组成的一个HTML字符串创建一个topRow()函数来解决此问题{1}}函数（ 就是这样！ ）：
