如何使用javascript将div附加到另一个div？

Question

var contentofsel=$("#"+a).html().trim();
alert (contentofsel);

$('#temstoredivid').append(
  "<div class="maincover" id="maincov1">" + 
  "  <div class="subcover" id="subcover1"> </div>" +
  "  <div class="forclose" id="forcloseid1"> </div>" + 
  "</div>");

$('#temstoredivid .maincov1').html(contentofsel);

我需要在div class subcover和id =“subcover1”中打印contentofsel的值。我已经尝试了上面的代码但没有工作。先生，请帮帮我。

您的字符串文字未正确包含

var contentofsel = $("#" + a).html().trim();
alert(contentofsel);

var $el = $('<div class="maincover" id="maincov1">' +
    '  <div class="subcover" id="subcover1 "></div>' +
    '  <div class="forclose" id="forcloseid1"></div>' +
    '</div>').appendTo('#temstoredivid');
//but since you are going to override the contents of .maincover element why are you adding 2 div's inside it in the above segment

$el.html(contentofsel);
