如何从jquery向div附加文本？

Question

我已经使用jquery附加了它，但它永远不会显示在下拉列表中

for (var key in data)
 {
    //alert(data[key]["type"] + data[key]["id"] + data[key]["message"]);
    //$str = $str+;
    $(".notiDiv").append('<div class="row" style="margin: 1px">\n\<div class="col - sm - 8">\n\<a href="#">' user have created a meeting'</a>\n\</div>\n\<div class="form - group col - sm - 4 text - right"  >\n\<a><span class=" glyphicon glyphicon - ok"></span></a>\n\<a><span class=" glyphicon glyphicon - remove"></span></a>\n\</div>\n\</div>\n');
 }
<div class="dropdown-menu dropdown-menu-custom " >
    <div class="notiDiv">

    </div>
</div></li>

Answer 1

您已经在类名和\\ n中使用了一些意外的空格，应该删除那些空格

您的代码将像

    $(".notiDiv").append('<div class="row" style="margin: 1px"><div class="col-sm-8"><a href="#!">user have created a meeting</a></div><div class="form-group col-sm-4 text-right"  ><a href="#!"><span class=" glyphicon glyphicon-ok"></span></a><a href="#!" ><span class=" glyphicon glyphicon-remove"></span></a></div></div>');

一旦您修复了所有Satpal建议的JS错误（如有）； 您将需要以编程方式初始化bootstrap下拉列表，如下所示：

for (var key in data)
 {
    //alert(data[key]["type"] + data[key]["id"] + data[key]["message"]);
    //$str = $str+;
    $(".notiDiv").append('<div class="row" style="margin: 1px">\n\<div class="col - sm - 8">\n\<a href="#">' user have created a meeting'</a>\n\</div>\n\<div class="form - group col - sm - 4 text - right"  >\n\<a><span class=" glyphicon glyphicon - ok"></span></a>\n\<a><span class=" glyphicon glyphicon - remove"></span></a>\n\</div>\n\</div>\n');
 }
 $(".notiDiv").dropdown(); //re-init dropdowm once all options has been appended

您可以在此处检查代码，我为您创建了一个示例

http://plnkr.co/edit/seRGvP?p=preview

$( document ).ready(function() {
  var data = {
    "flammable": "inflammable",
    "duh": "no duh"
  };
  $.each(data, function( key, value ) {
    //alert( key + ": " + value );
    $(".notiDiv").append('<div class="row" style="margin: 1px">\n\<div class="col - sm - 8">\n\<a href="#">' + value + '</a>\n\</div>\n\<div class="form - group col - sm - 4 text - right"  >\n\<a><span class=" glyphicon glyphicon - ok"></span></a>\n\<a><span class=" glyphicon glyphicon - remove"></span></a>\n\</div>\n\</div>\n');
  });
});

或与数组

$( document ).ready(function() {
   var data = ['aaaaaaaaaaaa','bbbbbbbbbbbbbb','ccccccccccccc','dddddddddddd','eeeeeeeeeeee','ffffffffffffff','ggggggggggg','jjjjjjjjjjjj'];
   $(data).each( function( index, value ) {
      //alert( index + ": " + value );
       //$( ".notiDiv" ).append( value );
       $(".notiDiv").append('<div class="row" style="margin: 1px">\n\<div class="col - sm - 8">\n\<a href="#">' + value + '</a>\n\</div>\n\<div class="form - group col - sm - 4 text - right"  >\n\<a><span class=" glyphicon glyphicon - ok"></span></a>\n\<a><span class=" glyphicon glyphicon - remove"></span></a>\n\</div>\n\</div>\n');
    });
});
