我有一个数据表,每次单击按钮时都应该刷新。
通过单击此按钮,我将使用 ajax 从 API 加载 JSON 流。数据将被处理,然后设置为数据表中的数据源。
我无法使用数据表的 ajax 内置功能。</p>
代码如下(为简单起见,删除了数据处理函数):
function loadBulletins(categoryID) {
$.ajax({
url: '/api/bulletins.ashx',
type: "POST",
dataType: "json",
data: { method: "getbulletins", iso3: iso3, catid:categoryID },
success: function (response) {
if ($.fn.dataTable.isDataTable('#bulletins-table')) {
table = $('#bulletins-table').DataTable();
table.clear();
table.data(response.data); //it seems like the update here doesn't work
table.draw(); //Table is not updated!!
//table.ajax.reload(); //it only works with ajax builtin
}
else {
$('#bulletins-table').DataTable({
deferRender: true,
"bLengthChange": false,
responsive: true,
"autoWidth": false,
"bInfo": false,
"bFilter": false,
data: response.data
});
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
console.log("loadBulletins Status: " + textStatus, "Error: " + errorThrown);
}
});
}
当用户点击某些按钮时,会调用上述函数,传递不同的categoryID值,从而从API加载不同的数据。
API返回的数据如下:
{
"data": [
["8", "Emergency Assessment: Faryab Province", "2", "2018", "00065098/download/", "", "", "", ""],
["", "XXX/NRC Emergency Shelter Assessment: Khogiani", "12", "2017", "00050404/download/", "", "", "", ""],
["7", "Emergency Market Assessment: Sayad and Qush Tepa Districts", "9", "2017", "000022544/download/", "", "", "", ""],
["6", "Emergency Assessment Bulletin: Darz Ab District (Jawzjan) - Rapid Assessment", "7", "2017", "019342/download/", "", "", "", ""],
["5", "Emergency Flash Update: Bala Buluk District: Farah Province - Conflict Rapid Assessment", "3", "2017", "1236.pdf", "", "", "", ""],
["4", "Emergency Flash Update: Faryab Province - Conflict Rapid Assessment", "1", "2017", "754.pdf", "", "", "", ""],
["3", "Emergency Flash Update: Kohistan District (Faryab) - Conflict Rapid Assessment", "11", "2016", "8973.pdf", "", "", "", ""],
["2", "Emergency Flash Update: Farah Province - Conflict Rapid Assessment", "11", "2016", "88394.pdf", "", "", "", ""],
["1", "Emergency Flash Update: Kunduz Province - Conflict Rapid Assessment", "10", "2016", "88308.pdf", "", "", "", ""]
]
}
第一次加载时,数据表工作正常,我可以看到数据。
第二次单击时,ajax 调用起作用,因为我可以在网络选项卡中看到响应,但数据表未更新。我已经尝试了文档中的所有建议,但它们都不起作用,它们通常指的是数据表的 ajax 内置功能。</p>
最佳答案
尝试
table.rows.add(response.data);
而不是
table.data(response.data);
或者销毁并重新初始化数据表。
