Question

我试图通过jQuery使用txt文件而不是数据库来提取选项。

如果文件保存在html文件下，一切正常，但是当我移动到PHP文件时，下拉菜单不会产生任何影响。

我首先调用了php中的代码

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" type="text/javascript"></script>

然后

<script>
$(function() {
    $("#pickup_location").change(function() {
    $("#drop_location").load("textdata/" + $(this).val() + ".txt");
    });
});
</script>

这是菜单

<div class="form-group col-sm-6">
    <label> <?php echo simontaxi_get_pickuppoint_title(); ?><?php echo simontaxi_required_field(); ?></label>
    <div class="inner-addon right-addon">
        <?php
        if ( 'predefined_place' === $predefined_place && 'dropdown' === $vehicle_places_display ) {
        $pickup_locations = simontaxi_get_locations( 'pickup_location' );
        $pickup_location = simontaxi_get_value( $booking_step1, 'pickup_location_new' );
        ?>
        <select name="pickup_location" id="pickup_location" class="selectpicker show-tick show-menu-arrow" data-width="100%" data-size="5">
            <option value=""><?php esc_html_e( 'Please select ' .simontaxi_get_pickuppoint_title() ) ?></option>
            <option value="416" >1</option>                                                                     
            <option value="532" >2</option>
            <option value="509" >3</option>
            <option value="505" >4</option>
        </select>
        <?php } else { 
        $plocation = simontaxi_get_value( $booking_step1, 'pickup_location' );
        if ( empty( $plocation ) ) {
            $plocation = simontaxi_get_value( $booking_step1, 'pickup_location_new' );
        }
        ?>

寻找你的帮助，这个问题让我陷入困境，因为它在html页面中运行良好

在PHP中删除菜单不起作用
