问题描述
如何在drawCallback中更改单元格中具有特定值的行的背景？
How can I change the background of a row that has a specific value in a cell inside a drawCallback?
$(table_id).DataTable({
//...
"drawCallback": function (settings) {
// here for each row, if row['type'] != "" then row.bgcolor ="yellow"
},
这是呈现我的表格的完整代码段：
This is the complete snippet that render my table:
$(table_id).DataTable({
"order": [[0, "desc"]],
serverSide: true,
"processing": true,
rowId: 'MessageID',
ajax: {
url: '/Controller/myRoute',
type: 'POST',
data: {table_id: table_id},
},
"initComplete": function( settings, json ) {
},
"createdRow": function (row, data, index) {
console.log("data is" + data);
},
columns: [
{
data: "Date",
"sortable": true,
"render": function (data) {
var formatted = data;
if (data.indexOf("/Date(") !== -1) {
var date = new Date(parseInt(data.replace("/Date(", "").replace(")/", ""), 10));
formatted = date.toString('dd/MM/yyyy HH:mm:ss');
}
return formatted;
}
},
{ data: "Message_id"},
{ data: "From_id"},
{ data: "Message_text" },
]
});
}
});
Inside / Controller / MyRoute我有一个代码可以从数据库中检索10个对象并将其作为JSON返回。
Inside /Controller/MyRoute I have code that retrieves 10 object from a DB and return them as JSON.
推荐答案
使用 createdRow callback：
Use createdRow callback:
$(document).ready(function() {
$('#example').dataTable({"sPaginationType": "full_numbers",
"createdRow": function (tr, tdsContent) {
if(tdsContent[4] === 'A') {
tr.style.backgroundColor = 'red';
}
}});
});
