Question

我使用jquery数据表加载数据，但是一旦调用成功，我将使用ajax调用删除行，然后必须重新加载数据。下面是附加的代码，在ajax调用部分中，一旦调用成功，我必须在其中插入刷新表逻辑。

/* Formatting function for row details - modify as you need */
function format ( d ) {
    // `d` is the original data object for the row
    return '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+
       '<tr>'+
            '<td>Full name:</td>'+
            '<td>'+d.lat+'</td>'+
        '</tr>'+
        '<tr>'+
            '<td>Extension number:</td>'+
            '<td>'+d.lon+'</td>'+
        '</tr>'+
        '<tr>'+
            '<td>Alert Type</td>'+
            '<td>'+d.alertExtraInformation1+'</td>'+

为了刷新表，我使用了table.ajax.reload();和table.fnDraw(false);，但是它不起作用。如何刷新数据表。

Answer 1

将.then()呼叫绑定到您的$.ajax()呼叫上。它比.done()或.fail()更可取，因为它可以同时捕获两者。您可以通过将响应记录到控制台来测试响应，也可以通过将其呈现到DOM或通过某种应用程序范围的状态（例如Vue，React / Redux或Angular）来使用响应。这是一个承诺，因此需要两个函数作为参数。

即。

$.get( "test.php" ).then(
  function() {
    alert( "$.get succeeded" );
  }, function() {
    alert( "$.get failed!" );
  }
);

或者，就您而言

$.ajax({
  type: "DELETE",
  contentType: "application/json; charset=utf-8",
  url: "http://localhost:9003/BPMNProcessInfo/1.0.0/delteAlert/"+row.id,
}).then(function() {
  alert( 'Success!' );
}, function() {
  alert( 'fail' );
})

Answer 2

$。ajax已完成调用函数的选项。在该函数中，您可以调用任何您想调用的东西：

$.ajax({
  type: "DELETE",
  contentType: "application/json; charset=utf-8",
  url: "http://localhost:9003/BPMNProcessInfo/1.0.0/delteAlert/"+row.id
 }).done(function() {
    table.ajax.reload();
 });

Answer 3

一般的本质是，在将请求执行到指定地址之后，如果请求成功，则成功回调将起作用：

     $.ajax({
        type: "DELETE",
        contentType: "application/json; charset=utf-8",
        url: "http://localhost:9003/BPMNProcessInfo/1.0.0/delteAlert/"+row.id,
        success: function(data_response){
            if(data_response.error <= 0 || data_response.error !== null){ //if you send data after query result
                //update all you need
            }
        },
        error: function(){
            //if error ajax
        }
    });
