我遇到了这种情况,我正试图从数据表中获取特定行的数据。我是dataTable的新手。

所以这是情况,
下面是我的数据表内容显示在图片中。 data table

bellow是我的数据表的代码



$(document).ready(function() {

    var table =$('#example').dataTable({
    	
    	"processing": true,
  	  "ajax": {
  		  		"url":'/myWeb/Controller/getUserList',
  		  		"dataSrc":""
  	  		   },	  		   
  	  "columns": [
  	              { "data": "userName"},
  				  { "data": "roles" },
  				 
	  				
	  				
  			          {
	                  data:   "userName",
	                  render: function ( data, type, row ) {	
	                	 
	                      if ( type === 'display' ) {
	                          return '<button type="button" id='+data+' class="btn btn-default btn-sm"  data-toggle="modal" data-target="#editUser" data-whatever="@getbootstrap()" onclick="getUserName(this.id)" > <span class="glyphicon glyphicon-pencil"></span> Edit </button>';	                         
	                      }
	                      //alert(data);
	                      return data;
	                  }
	              },
	              {
	            	  data :	"userName",
	                      if ( type === 'display' ) {
	                          return '<button type="button" id='+data+' class="btn btn-default btn-sm" onclick="countUserRecord(this.id)"> <span class="glyphicon glyphicon-trash"></span> Delete </button>';	                         
	                      }
	                      //alert(data);
	                      return data;
	                  }
	              }
  	             	          
  	          	],
    "paging":   false,
    "info":     false,
    "filter":   false,
    "sort":		false
    
    });
} );
&#13;
&#13;
&#13;

在我传递userName的删除按钮上,我也想传递角色, 所以我试过这个

&#13;
&#13;
role = row.roles;
userName = row.userName;
status = row.status;
alert("username :"+userName+" role: "+role); 
	                
&#13;
&#13;
&#13;

但是当我这样做时,每个用户都会扮演不同的角色。它给了我错误的用户角色。

贝洛是我的Json结构,我从DB获得。

&#13;
&#13;
[
{"userName":"admin",
"password":null,
"roles":"Admin",
"status":"Active",
"email":"emailAdmin"},

{"userName":"varun",
"password":null,
"roles":"User",
"status":"Active",
"email":"emailVarun"},

{"userName":"bob",
"password":null,
"roles":"Admin",
"status":"Active",
"email":"undefined"}
]
&#13;
&#13;
&#13;

我想要做的是当我点击删除用户按钮时,它应该传递userName和角色,我该怎么做,

答案 0 :(得分:0)

这应该可以解决问题:

$('table').on('click','.addDeleteClassToDeleteBtns',function(){
     var containerRow = $(this).parents('tr');
     var userName    = containerRow.find('td:first-child').html();
     var role         = containerRow.find('td:nth-child(2)').html();
     alert(role+' '+userName);
});

function countUserRecord(deleteId){
     var containerRow = $('#deleteId').parents('tr');
     var userName    = containerRow.find('td:first-child').html();
     var role         = containerRow.find('td:nth-child(2)').html();
     alert(role+' '+userName);
}

您可以编辑选择器以更好地适合您的代码。
