我试图使特定列的单元格都具有与它们相关联的data-ip
属性,以便我可以在以后需要数据时使用jQuery读取它。我可以创建一个隐藏的单独列,其中包含ip
,但我想先尝试这个方法。
我正在尝试将更具可读性的hostname
列与ip
关联。以下是aoColumns
的列:
{"sTitle": "Hostname", sName: "host", sWidth: "30%", sClass: 'host', mData:
function (source) {
return source.hostname
}
}
正如你在代码中看到的,我有source.hostname
,它用JSON hostname
填充td
,但是我想应用包含source.ip
数据的data-ip
属性。这可能吗?
编辑整个jQuery元素:
$('#servicesTable').dataTable({
'aaData': servicesJson['registered_services'],
'aoColumns': [
{"sTitle": "Hostname", sName: "host", sWidth: "30%", sClass: 'host', mData:
function (source) {
return source.hostname
}
},
{"sTitle": "Service", sName: "service", sWidth: "30%", sClass: 'service', mData: "serviceName"},
{"sTitle": "Monitored?", sName: "monitored", sWidth: "10%", sClass: 'monitored', mData:
function (source) {
if (typeof source.active === 'undefined')
return '';
var monitor = source.active;
if (monitor == 1)
return "<input type='checkbox' class='monitor' name='monitored' checked />";
else
return "<input type='checkbox' class='monitor' name='monitored'/>";
}
},
{"sTitle": "Status", sName: "status", sWidth: "15%", sClass: 'status', mData: "status"},
{"sTitle": "URL", sName: "url", sWidth: "5%", sClass: 'url right', mData:
function (source) {
if (typeof source.url === 'undefined' || source.url == '')
return '';
return "<a class='ui-icon ui-icon-link' href='" + source.url + "'>NAGIOS</a>";
}
},
{"sTitle": "Add/Remove", sName: "add-remove-new", sWidth: "15%", sClass: 'add-remove-new', mData:
function (source, type, val) {
if (typeof source.addRemove === 'undefined')
return "<button class='add-remove-new' type='button'>Remove</button>";
else
return "<button class='add-remove-new' type='button'>Add</button>";
}
},
],
'bJQueryUI': true,
'bInfo': false,
'bPaginate': false,
'bSort': false,
'bFilter': true,
'iDisplayLength': 25,
"fnRowCallback": function (nRow, aData, iDisplayIndex, iDisplayIndexFull) {
//function that is called everytime an element is added or a redraw is called
//aData[] is an arraw of the values stored in datatables for the row
//to change a row's html use $('td:eq('+index+')', nRow).html( html here ); where index is the index of the td element in the row
}
});
当然。使用jQuery的.data()
来设置td
的data-ip
,如下所示:
$('#my-td').data('ip', source.ip);

Update:在你提供了更多关于你的代码的细节之后,我做了很多关于DataTables插件的阅读,它似乎确实是一个斗争,通过API直接做这种操作。我建议您按照自己的想法添加一个隐藏的额外列,或者按以下方式执行:
return source.hostname+'<span class="id-info">'+source.ip+'</span>';
span
当然会被隐藏,然后你的页面会有一些jQuery来选择表创建后的信息,并把它作为data-ip
给td
。
在代码丑陋方面没有太大区别,但至少它不会在页面上留下隐藏列,因为您的jQuery可以在将IP添加到data-ip
属性后删除span
。
