1-我写了什么代码来获取此代码中的所有"想要访问"元素，没有其他元素，例如"某些数据"，并且只想要在div类bestMFdtl2中具有的元素。
2-如果我想要根据选择如何执行此操作在此代码中使用一些特定元素，我正在使用 HTML Jerico解析器。请帮助我，那些在阅读代码时遇到问题的人我很抱歉，但你是程序员，我以为你喜欢这个。
3-如何从标签中获取href链接。

鉴于评论，我相信这就是你所追求的。
var x = document.getElementsByClassName("bestMFdt12");
for (var i = 0; i < x.length; i++){
var x2 = x[i].getElementsByClassName("b-12");
for (var j = 0; j < x2.length; j++) {
//Do something with the elements, access them with "x2[j]", these loops will go through every element within both classes and allow you to process them
//Example:
var current = x2[j];
}
}
这应该得到所有"bestMFdt12"元素的数组，并且对于每个元素，在里面搜索任何"b-12"元素。在我放置示例的位置，您可以添加代码来处理这些元素。
