您可以尝试以下脚本：

var MEDIAmedia_library: function() {
     var formfield = null;

     var wireframe;

     $(\'body\').on(\'click\', \'#click-event-selector\',function(e) {
         e.preventDefault();
         if (wireframe) {
             wireframe.open();
             return;
         }

         wireframe = wp.media.frames.wireframe = wp.media({
             title: \'Media Library Title\',
             button: {
                 text: \'Media Library Button Title\'
             },
             multiple: false
         });

         wireframe.on(\'select\', function() {
             attachment = wireframe.state().get(\'selection\').first().toJSON();
             console.log(attachment);
             $(\'#input-field-selector\').val(attachment.url);
         });

         wireframe.open();
     });
    }

#input-field-selector 用于插入选定对象属性的输入字段值

您还可以将此函数包装在任何jquery模式中
