javascript - 使用 AJAX 调用搜索失败

问题描述

数据搜索适用于普通表数据。当我用 Ajax 调用填充表格主体时，搜索不起作用。

我正在使用 AJAX 调用来填充表格主体。如果有一些没有 Ajax 调用的虚拟数据，我的表搜索效果很好。在 Ajax 调用之后，搜索不起作用......

解决方案

The issue is not with your ajax calls 
rather it's with your data-table initializing

参考您的 codepen 链接： https ://codepen.io/jithendraathipatla/pen/JQMxvg?editors=1111

这样做：在 document.ready

$(document).ready(function() {
    $('#myTable').DataTable();
 function filterGlobal () {
    $('#myTable').DataTable().search(
        $('#global_filter').val(),

    ).draw();
}

function filterColumn ( i ) {
    $('#myTable').DataTable().column( i ).search(
        $('#col'+i+'_filter').val(),

    ).draw();
}

    $('input.global_filter').on( 'keyup click', function () {
        filterGlobal();
    } );

    $('input.column_filter').on( 'keyup click', function () {
        filterColumn( $(this).parents('tr').attr('data-column') );
    } );
} );

并在您的 js 文件中将您的代码替换为：

var waitlistTable=[];
waitlistdatashow();
function waitlistdatashow(){
    console.log("hi");
    var data = {"hosted_event_id": "testkonfhub-php-ban963c6ec2",
    "user_id" : "1548232247"
     };
// document.getElementById("userdetails").innerHTML = "<i class=\"fa fa-refresh fa-spin\" style=\"font-size:48px\"></i> ";
    $.ajax({
    url: "https://mr6akjmp7f.execute-api.us-east-2.amazonaws.com/default/konfhub_event_display_wailist_details",
    type: "POST",
    data: JSON.stringify(data),
    dataType: "json",
    async:false,
    success: function (data) {

        console.log(data);

        waitlistTable=data.participant_details;
        console.log(waitlistTable);
        //document.getElementById("event_name1").innerHTML = waitlistTable.event_name;
        for(var i=0; i < waitlistTable.length; i++){
            $("#userdetails1").append(
               //"<th>Date & Time of Purchase</th>" +
                "<tr>"+
                "<td style='cursor: default'>" + waitlistTable[i].name + "</td>" +
                "<td style='cursor: default'>" +
                "    <span class=\"block-email\" >" + waitlistTable[i].email_id.slice(0, 25) + "</span>" +
                "</td>" +
                "<td class=\"desc\">" + waitlistTable[i].phone_number + "</td>" +
                "<td class=\"desc\">" + waitlistTable[i].organisation + "</td>" +
                 "<td class=\"desc\"  id=\"waitlisttext\" style=\"color:orange\">" + waitlistTable[i].ticket_status + "</td>" +
                // "<td><textarea  id=" + "lead_text".concat(no_of_participant) + " rows=\"1\" cols=\"50\" type=\"text\" style=\"width:100%;border: 1px solid lightslategrey;padding: 4px;border-radius: 4px;\" placeholder=\"write comments here..\">" + returnLeadText(king[no_of_participant].misc) + "</textarea></td>" +
               // "<td><span id=" + "approve".concat(no_of_participant) + " class='fas fa-check-circle click-check' onclick=\"approveWaitlist(" + no_of_participant + ")\" style=\"cursor:pointer;font-size: 25px;color:green\" data-toggle=\"tooltip\" title=\"Approve\">&nbsp&nbsp</span>"+
                //"<div id=" + "delete-waitlist".concat(no_of_participant) + " class='far fa-times-circle click-check1' onclick=\"deleteWaitlistRecord(" + no_of_participant + ")\" style=\"cursor:pointer; font-size: 25px;color:red\" data-toggle=\"tooltip\" title=\"Reject\"></div></td>" +
                "<\tr>"+
                "<hr>"


            );
            // if(waitlistTable[i].status=="ACTIVE"){
            //     document.getElementById("refundbtn".concat(i)).style.display = "block";
            //     document.getElementById("cancelbtn".concat(i)).style.display = "block";
    }
    $('#myTable').DataTable();
}
    });
}
