我有以下javascript，它涉及大约6个元素。前三个打开一个thickbox进行媒体上传，而不是单击指定的按钮，后三个目标是该媒体的src也应该转储的输入元素。

我遇到的问题是，如果我点击按钮#upload-background-image-one 然后找到我想要的媒体，单击“发送到帖子”将其插入：#background-size-three 这是第三个输入。应将其置于：#background-size-one 但事实并非如此。事实上，任何点击打开厚盒媒体上传器的按钮都会将“发送到帖子”的内容放入第三个输入框。

那么，我如何针对每个可以打开的厚盒子的特定输入？（我以为我已经是了）

Js:

( function($) {
    $(document).ready(function() {

        // Show WP Thickbox with image uploader.
        $(\'#upload-background-image-one\').click(function() {
            formfield = $(\'#background-size-one\').attr(\'name\');
            tb_show(\'\', \'media-upload.php?type=image&TB_iframe=true\');
            return false;
        });

        // Take the selected image and insert only the src path into the text field.
        window.send_to_editor = function(html) {
            img_url = $(\'img\', html).attr(\'src\');
            $(\'#background-size-one\').val(img_url);
            tb_remove();
        }

        // Show WP Thickbox with image uploader.
        $(\'#upload-background-image-two\').click(function() {
            formfield = $(\'#background-size-two\').attr(\'name\');
            tb_show(\'\', \'media-upload.php?type=image&TB_iframe=true\');
            return false;
        });

        // Take the selected image and insert only the src path into the text field.
        window.send_to_editor = function(html) {
            img_url = $(\'img\', html).attr(\'src\');
            $(\'#background-size-two\').val(img_url);
            tb_remove();
        }

        // Show WP Thickbox with image uploader.
        $(\'#upload-background-image-three\').click(function() {
            formfield = $(\'#background-size-three\').attr(\'name\');
            tb_show(\'\', \'media-upload.php?type=image&TB_iframe=true\');
            return false;
        });

        // Take the selected image and insert only the src path into the text field.
        window.send_to_editor = function(html) {
            img_url = $(\'img\', html).attr(\'src\');
            $(\'#background-size-three\').val(img_url);
            tb_remove();
        }
    });

})(jQuery);
