Small problems with jquery each and splicing

selector + traversal

$('div').each(function (i){
  i就是索引值
  this 表示获取遍历每一个dom对象
});

$('div').each(function (index,domEle){
  index就是索引值
 domEle 表示获取遍历每一个dom对象
});

Another traversal method

1) First get a collection object

2) Traverse each element of the collection object

var d=$("div");
$.each(d,function (index,domEle){
 d是要遍历的集合
 index就是索引值
 domEle 表示获取遍历每一个dom对
});

For string splicing problems, you can use double quotes and single quotes, and use them when appropriate.

Code used this time:

$(function(){
    $('.shiting').each(function (i){
        $(this).html('<iframe frameborder="no" border="0" marginwidth="0" marginheight="0" width=330 height=86 src="//music.163.com/outchain/player?type=2&id='+ $(this).attr("data-songid") +'&auto=0&height=66"></iframe>')
    });
})

When writing a website to embed NetEase Cloud code, due to website optimization, the page needs to use less iframe framework, so I have to use jQuery to dynamically embed it.
