Question

在Select2 Box中，根据选择的ID，系统必须相互比较一些数据。例如：在市场中，客户可以为其物业购买一些套餐。每个属性都有一个包。在Property Package中具有packagePosition数据。从SelectBox中选择属性时，如果选择了Property Package的packagePosition>任何Package的packagePosition，则系统必须给出如下错误：该属性不适用于此软件包。如何在Ajax或Javascript中做到这一点？

查看代码：

    <?php
        foreach($all_packs as $get) { ## This is showing All Packages in Market. ?>
    <fieldset class="mb-3" <?php if($get->packageType == 2){echo'hidden';}?>>
                                <legend class="text-uppercase font-size-sm font-weight-bold"></legend>
                                <div class="form-group">
                                    <label><?php echo $this->lang->line('packages_package_choose_property'); ?>:</label>
                                    <select id="propertyDetector" class="form-control select-search" name="estateId" data-fouc>
                                        <optgroup label="<?php echo $this->lang->line('dashboard_properties'); ?>">
                                            <option value=""><?php echo $this->lang->line('general_select'); ?></option>
                                            <?php foreach ($estateList as $estate) { if ($estate->estateStatus == 1) { ## This is showing All Properties of Customer in Market for buying available Package to his Property. ?>
                                                <option value="<?php echo $estate->estateId; ?>" <?php if($estate->packagePosition < $get->packagePosition && $estate->estatePackage != '') {echo 'disabled';}?>><?php if($this->session->userdata('people_lang') == 'en') {echo $estate->estateTypeEng;} elseif($this->session->userdata('people_lang') == 'ar') {echo $estate->estateTypeAr;} ?> | <?php echo $estate->cityName. ' | ' .$estate->estateAddress ?></option>
                                            <?php } } ?>
                                        </optgroup>
                                    </select>
                                </div>
                            </fieldset>


    <span id="error">This Package Not Available to your Property</div>


<?php } ?>

我的Javascript代码：

$(document).ready(function(){
  $('#propertyDetector').addClass('input_error');
  $('#error').show();

  $('#propertyDetector').change(function () {
    var selectedValue = $(this).val();
    if (selectedValue == <?php echo $get->packagePosition < $estate->packagePosition) {
      $(this).addClass('input_error');
      $('#error').show();
    }else{
      $(this).removeClass('input_error'); //remove class
      $('#error').hide();//hide error message
    }
  });
});

Codeigniter-选择框比较过程如何完成？
