Question

如何修改代碼以將每個單元格信息顯示到工具提示中？

http://datatables.net/release-datatables/examples/advanced_init/events_post_init.html

$(document).ready(function() { 
/* 
* First step is to create title attributes for the rows in the table 
* This isn't needed if the required 'title' attribute is already set in the HTML in the 
* DOM 
*/ 
$('#example tbody tr').each(function() { 
var sTitle; 
var nTds = $('td', this); 
var sBrowser = $(nTds[1]).text(); 
var sGrade = $(nTds[4]).text(); 

if (sGrade == "A") 
sTitle = sBrowser+' will provide a first class (A) level of CSS support.'; 
else if (sGrade == "C") 
sTitle = sBrowser+' will provide a core (C) level of CSS support.'; 
else if (sGrade == "X") 
sTitle = sBrowser+' does not provide CSS support or has a broken implementation. Block CSS.'; 
else 
sTitle = sBrowser+' will provide an undefined level of CSS support.'; 

this.setAttribute('title', sTitle); 
}); 

/* Init DataTables */ 
var oTable = $('#example').dataTable(); 

/* Apply the tooltips */ 
oTable.$('tr').tooltip({ 
"delay": 0, 
"track": true, 
"fade": 250 
}); 
}); 

Answer 1

你可以通過簡單的setAttribute每個TD

$('#example tbody tr td').each(function() { 
    this.setAttribute('title', $(this).text()); 
}); 

設置標題和呼籲TD

oTable.$('td').tooltip({ 
"delay": 0, 
"track": true, 
"fade": 250 
}); 

Answer 2

提示你可以做

{ "sTitle": "...", ... 
    'fnCreatedCell': function(nTd, sData, oData, iRow, iCol) { 
     nTd.title = 'Some more information'; 
    } 
} 

在您的列配置中。您可以像這樣輕鬆使用所有行數據。 原因，這一定不能錯過：

oTable.$('td').tooltip({ 
    "delay": 0, 
    "track": true, 
    "fade": 100 
});
