我想使用.each（）函数jQuery在（.pin_lists li）data-col中添加来自（pin_head＆gt; div）的文本。我在这里很难对数值进行编码。

请帮助我走好路。 :) 我是jQuery的新手。

我想您希望每列的标题都是每个单元格的属性data-col。

您可以这样做：

$(document).ready(function() {
  var list = $('.pin_lists li');
  $('.pin_head div').each(function(item) {
    var _this = this;
    list.each(function(element) {
      $($(this).children()[item]).attr('data-col', $(_this).find('strong').text())
    })
  })
})

使用以下jQuery根据data-col div的内容在li上动态创建pin_head元素：

$(".pin_lists div").each(function() {
    $(this).attr("data-col", $($(".pin_head").children()[$(this).index()]).find("strong").text());
});

现场演示： 

$(".pin_lists div").each(function() {
    $(this).attr("data-col", $($(".pin_head").children()[$(this).index()]).find("strong").text());
});

在jQuery中你可以这样做：

$("#yourElement").data("yourKeyName", "yourValue")

有关其他信息，请访问文档的this site

答案 3 :(得分：0)

你可以做这样的事情

 var array=[];
$('.pin_head > div').each(function (index,obj) { 

   array[index]= $(this).text();

});

$('li>div').each(function (index,obj) { 
    var data= $(this).attr("data-col",array[index]);
});
