单击列表项应显示与该列表项相关的表

Question

当用户选择列表项时,应显示与该列表项关联的表.我有脑筋,我想我已接近解决它或者至少是关于如何解决问题的想法.找到每个的长度,如果长度彼此相等,则创建显示/单击功能.答案应该是可以用于具有不同表的数百个列表项的答案.

JS

function count(){
    var list = jQuery('ul li')

    var table = jQuery('table tbody')

    if(table.length == list.length){
        jQuery(list).click(function(){
            //show the table length that is equal to the list length 

        })
    }
}

如果要根据列表中的位置将列表项关联到tbody元素,可以将该.index()方法与.eq()以下内容结合使用:

var list = jQuery('ul li a')
var table = jQuery('table tbody').hide()
    
list.click(function(e) {
  table.hide().eq(list.index(this)).show()
})
