Php 为什么我输入的值在失去焦点时总是消失？

我不擅长PHP

我有一个组合框，其中包含SQL查询中的下拉选项。每当我键入列表中没有的内容，然后将焦点切换到另一个对象时，我以前在该组合框中键入的内容总是消失。 但如果我键入的值包含在options/dropwdown列表中，则不会发生这种情况

如何使我在组合框中键入的任何内容不消失？如何获得它的价值

以下是创建组合框的脚本：

$form->addField("artikel", "artikel", "combobox", [
    "valueField"     => "ARTIKEL",
    "labelField"     => "ARTIKEL",
    "searchField"    => "ARTIKEL",
    "initialize"     => "load_Artikel",
    "placeholder"    => "",
    "label"          => "Artikel",
    "required"       => true,
    "onChange"       => "change_KDPenerimaan",
    "required_error" => "Article is required"
]);

这就是功能：

function addField($id, $name, $type, $options = array())
{
    $value = isset($options["value"]) ? $options["value"] : "";
    $placeholder = isset($options["placeholder"]) ? $options["placeholder"] : "";
    $required = isset($options["required"]) ? $options["required"] : false;
    $required_error = isset($options["required_error"]) ? $options["required_error"] : "";
    $label = isset($options["label"]) ? $options["label"] : "";
    if ($type == "general" || $type == "textarea" || $type == "number" || $type == "date") {
        $newfield = new InputForm_Field($id, $name, $type, $value, $label, $placeholder, $required, $required_error);
        if (isset($options['maxLength'])) {
            $newfield->setMaxLength($options["maxLength"]);
        }
    } else {
        if ($type == "hidden") {
            $newfield = new InputForm_Field($id, $name, $type, $value);
        } else {
            if ($type == "label") {
                $newfield = new InputForm_Field($id, $name, $type, $value, $label);
            } else {
                if ($type == "listbox") {
                    $keyField = isset($options["keyField"]) ? $options["keyField"] : "0";
                    $textField = isset($options["textField"]) ? $options["textField"] : "1";
                    $newfield = new InputForm_Field_ListBox($id, $name, $options["listType"], $keyField, $textField,
                        $options["options"], $value, $label,
                        $placeholder, $required, $required_error);
                    if (isset($options['listEmpty'])) {
                        $newfield->setListEmpty($options["listEmpty"]);
                    }
                } else {
                    if ($type == "combobox" || $type == "autocomplete") {
                        $newfield = new InputForm_Field_Combobox($id, $name, $type, $options);
                    } else {
                        if ($type == "radio") {
                            $newfield = new InputForm_Field_Radio($id, $name, $options["options"], $value, $label,
                                $required, $required_error);
                        } else {
                            if ($type == "inputbutton") {

                                    $value, $label, $placeholder, $required, $required_error);
                            } else {
                                if ($type == "file") {
                                    $buttonText = isset($options["buttonText"]) ? $options["buttonText"] : "Select File";
