出现错误

new_ Uncaught ReferenceError: get_class_sections is not defined(…)

在ajax的onchange函数中，我如何解决这个问题，目前为止看到的分辨率不适用于我。

<div class="form-group">
    <label class="col-sm-3 control-label">State</label>
    <div class="col-sm-5">
        <select name="state" class="form-control select2" style="width:100%;" data-validate="required" id="State" 
        data-message-required="State Required" onchange="return get_state_cities(this.value)">
        <option value="">Select</option>
            <?php 
            $notarray = DataDB::getInstance()->select_from('state');
            foreach($notarray as $row):
            ?>
                <option value="<?php echo $row['state'];?>"> <?php echo $row['state'];?> </option>
            <?php
            endforeach;
            ?>
        </select>
    </div>
</div>

ajax函数

<script type="text/javascript">
function get_state_cities(state) {
    $.ajax({
        url: 'func.php',
        data: { param1: state, action: city}
        success: function(response)
        {
            jQuery('#city_selector_holder').html(response);
        }
    });
}

对于遇到同样问题的人，您的ajax函数应该是这样的

script type="text/javascript">
function get_state_cities(state) {
    $.ajax({
        url: 'func.php',
        data: {stat: state},
        success: function(data)
        {
            jQuery('#city_selector_holder').html(data);
        }
    });
}
