AJAX仅适用于1个文本框

Question

所以我有这个带有文本框的表单，当您在文本框中键入时，您会从AJAX输出的表格中获得搜索结果。

这适用于1个文本框，但我似乎无法使用其他文本框。

我还在学习如何编程，所以我的代码并不完美，但最重要的是它首先应该有效。

我希望你们能帮助我。

所以这基本上是我的代码如何工作，我省略了包含文本框的HTML部分。

AJAX

<script>

function makeTable(data) {
    var tbl_body = "";
    $.each(data, function() {
        var tbl_row = "";
        $.each(this, function(k , v) {
            tbl_row += "<td>"+v+"</td>";
        })
        tbl_body += "<tr>"+tbl_row+"</tr>";
    })
    return tbl_body;
}

function getEmployeeFilterOptions(){
    var opts = [];
    $checkboxes.each(function(){
        if(this.checked){
            opts.push(this.name);
        }
    });
    return opts;
}   

function updateEmployees(opts){
    $.ajax({
    type: "POST",
    url: "submit.php",
    dataType : 'json',
    cache: false,
    data: {filterOpts: opts},
    success: function(records){
        $('#employees tbody').html(makeTable(records));
    }
});
}

var $checkboxes = $("input:checkbox");
$checkboxes.on("change", function(){
    var opts = getEmployeeFilterOptions();
    updateEmployees(opts);
});

updateEmployees();

$('#boekingsnummer_1').keyup(function(){        
    updateEmployeesText($(this).val());        
});

$('#huiscode_1').keyup(function(){        
    updateEmployeesText($(this).val());        
});

function updateEmployeesText(val){        
    $.ajax({
    type: "POST",
    url: "submit.php",
    dataType : 'json',
    cache: false,
