jQuery中Datatables增加跳转到指定页功能
下面一段代码是关于datatable增加跳转到指定页功能，具体代码如下所示：
var
mytable=$('#datatables');
mytable.dataTable(
{
"sDom":
"<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>",
"sPaginationType":
"bootstrap",
"bProcessing":
true,
"bServerSide":
true,
"sAjaxSource":
"/user/list",
"aoColumns":
[
{
"mData":
"Id"
},
{
"mData":
"Username"
},
{"mData":function(obj){
return
obj.group;
}},
{"mData":"yiyuan"},
{"mData":function(obj){
return
obj.keshi;
}},
{"mData":function(obj){
if(obj.Status==1){
return
"使用中";
}else{
return
"禁用";
}
}},
{"mData":
function(obj){
var
del="";
if(isAdmin){
del='<a
data-title="'
+obj.Id+'"
class="btnbtn-danger"><iclass="icon-wrenchicon-white"></i>删除</a>';
}
return
'<adata-title="'
+obj.Id+'"
class="btnbtn-success"href="#"rel="externalnofollow"rel="externalnofollow"rel="externalnofollow"rel="externalnofollow"rel="externalnofollow"rel="externalnofollow"><iclass="icon-editicon-white"></i>修改</a>'
+' '+del;
},bSortable
:false}
],
"fnDrawCallback":
function(){
var
oTable=$("#datatables").dataTable();
$('#redirect').keyup(function(e){
if($(this).val()
&&$(this).val()>0){
var
redirectpage=$(this).val()-1;
}else{
var
redirectpage=0;
}
oTable.fnPageChange(
redirectpage);
});
}
});

好了，下面看下jQuerydatatable中加入双击跳转功能
$('#topicDgtbody').on('dblclick','tr',function(){
varself=$(this);
varid=self.find('.td-id').text();
varname=self.find('.td-name').text();
creatIframe("/post/postList.do?id="+id+"&name="+name,"帖子管理");
});
ps:点击话题列表中的一行，跳转到帖子列表中。
