Question

我正试图在页面加载时调用fwre-sel-region_id的更改方法。通常，在选择id的选项select更改后调用此方法。这不适用于我，因为select id只有一个有效的选项。所以我想通过javascript更改select id后调用它。我现在成功地改变了选择id的索引，我希望它能调用fwre-sel-region_id的改变方法。

<script type="text/javascript">
setTimeout(function() {
    if ($('fwre-sel-region_id')) {
        $('fwre-sel-region_id').addEvent('change', function() {
            $('fwre-sel-city_id').options.length = 0;
            if (this.value == '(add-value)') return;
            var img = new Element('img', {
                'id': 'fwre-wait-region',
                'style' : 'margin:0;padding:0;',
                'src': '/administrator/components/com_fwrealestatelight/assets/images/spinner.gif'
            });
            img.inject($('fwre-sel-city_id'), 'after');
             new Request.JSON({
                url: '/properties?format=raw&task=loadDictionary',
                onSuccess: function(obj) {
                    if ($('fwre-wait-region')) $('fwre-wait-region').dispose();
                    if (obj.msg) {
                        alert(obj.msg);
                    } else if (obj.data) {
                        for (var i = 0; i < obj.data.length; i++) {
                            var op = new Element('option', {
                                'value': obj.data[i].id
                            });
                            op.inject($('fwre-sel-city_id'));
                            op.innerHTML = obj.data[i].name;
                        }
                    }
                    $('fwre-sel-city_id').fireEvent('change');
                }
            }).get({'parent_id':$('fwre-sel-region_id').value,'dname':'city_id'});
        });
    }
}, 500);

我正在尝试使用此脚本调用上面的方法

<script type="text/javascript" >
    window.addEvent('load', function(){
     var country = document.id('fwre-sel-country_id');
     var region = document.id('fwre-sel-region_id');
     $(country).selectedIndex = 1;
    region.fireEvent('change');
    });
    </script>

我的脚本都在文件和html的脚本下面，但是当region.fireEvent（'change'）;执行它不会让它回到第一种方法。为什么会这样？
