我正在尝试将多个图像上载到媒体库，然后我可以获取图像的URL并将其插入网站上的自定义页面，但由于某些原因，当我单击其他输入按钮时，它不起作用，也不会显示媒体库上载下拉列表并选择第一个输入文本字段。我不明白为什么我不能使用其他输入同时上传多个图像。

有人能看出我做错了什么吗？

这是JS：

<script language="JavaScript">
    jQuery(document).ready(function() {
    jQuery(\'#upload_image_button\').click(function() {
    formfield = jQuery(\'#upload_image\').attr(\'name\');
    tb_show(\'\', \'media-upload.php?type=image&TB_iframe=true\');
    return false;
    });

    window.send_to_editor = function(html) {
    imgurl = jQuery(\'img\',html).attr(\'src\');
    jQuery(\'#upload_image\').val(imgurl);
    tb_remove();
    }

    });
    </script>

<tr valign="top">
        <td>Upload Ad for Position 1</td>
        <td><label for="upload_image">
            <input id="upload_image" type="text" size="36" name="upload_ad1_doc" value="<?php echo $gearimage; ?>" />
            <input id="upload_image_button" type="button" value="Upload Image" />
            <br />Enter an URL or upload an image for the ad.
            </label>
        </td>
    </tr><br /><br />
    <tr valign="top">
        <td>Upload Ad for Position 2</td>
        <td><label for="upload_image">
            <input id="upload_image" type="text" size="36" name="upload_ad2_doc" value="<?php echo $gearimage; ?>" />
            <input id="upload_image_button" type="button" value="Upload Image" />
            <br />Enter an URL or upload an image for the ad.
            </label>
        </td>
    </tr><br /><br />
    <tr valign="top">
        <td>Upload Ad for Position 3</td>
        <td><label for="upload_image">
            <input id="upload_image" type="text" size="36" name="upload_ad3_doc" value="<?php echo $gearimage; ?>" />
            <input id="upload_image_button" type="button" value="Upload Image" />
            <br />Enter an URL or upload an image for the ad.
            </label>
        </td>
    </tr>
