Answer 1

Just try to cover most solutions:

1. use tb_show("", "media-upload.php?type=image&TB_iframe=true"); and window.send_to_editor

   • problem: has no standard wp.media UI

   • in js code:

     jQuery("#my_button").click(function() {
         tb_show("", "media-upload.php?type=image&TB_iframe=true");
         return false;
     });
     window.send_to_editor = function(html) {
         console.log(html);
         tb_remove();
     }
     

2. use wp.media({frame: 'post'})

   • problem: cannot custom UI elements, such as: title, button

   • in js code:

     function clearField(){
         #remove file nodes
         #...
     }
     
     var frame = wp.media({frame: 'post'});
     
     frame.on('close',function() {
         var selection = frame.state().get('selection');
         if(!selection.length){
             clearField();
         }
     });
     
     frame.on( 'select',function() {
         var state = frame.state();
         var selection = state.get('selection');
         if ( ! selection ) return;
     
         clearField();
     
         selection.each(function(attachment) {
             console.log(attachment.attributes);
         });
     });
     
     frame.open();
     

3. use wp.media.editor with wp.media.editor.open( editor_id )

   • problem: cannot custom UI elements, such as: title, button

   • in js code: https://wordpress.stackexchange.com/questions/75808/using-wordpress-3-5-media-uploader-in-meta-box#75823

4. use wp.media with rewrite wp.media.controller.Library and retrieve attachment in select

   • problem: complicated ..., but once you understand it, it all make sense, and it is my finial solution

   • in js code:

     /**
      * Please attach all the code below to a button click event
      **/
     
     //create a new Library, base on defaults
     //you can put your attributes in
     var insertImage = wp.media.controller.Library.extend({
         defaults :  _.defaults({
                 id:        'insert-image',
                 title:      'Insert Image Url',
                 allowLocalEdits: true,
                 displaySettings: true,
                 displayUserSettings: true,
                 multiple : true,
                 type : 'image'//audio, video, application/pdf, ... etc
           }, wp.media.controller.Library.prototype.defaults )
     });
     
     //Setup media frame
     var frame = wp.media({
         button : { text : 'Select' },
         state : 'insert-image',
         states : [
             new insertImage()
         ]
     });
     
     //on close, if there is no select files, remove all the files already selected in your main frame
     frame.on('close',function() {
         var selection = frame.state('insert-image').get('selection');
         if(!selection.length){
             #remove file nodes
             #such as: jq("#my_file_group_field").children('div.image_group_row').remove();
             #...
         }
     });
     
     
     frame.on( 'select',function() {
         var state = frame.state('insert-image');
         var selection = state.get('selection');
         var imageArray = [];
     
         if ( ! selection ) return;
     
         #remove file nodes
         #such as: jq("#my_file_group_field").children('div.image_group_row').remove();
         #...
     
         //to get right side attachment UI info, such as: size and alignments
         //org code from /wp-includes/js/media-editor.js, arround `line 603 -- send: { ... attachment: function( props, attachment ) { ... `
         selection.each(function(attachment) {
             var display = state.display( attachment ).toJSON();
             var obj_attachment = attachment.toJSON()
             var caption = obj_attachment.caption, options, html;
     
             // If captions are disabled, clear the caption.
             if ( ! wp.media.view.settings.captions )
                 delete obj_attachment.caption;
     
             display = wp.media.string.props( display, obj_attachment );
     
             options = {
                 id:        obj_attachment.id,
                 post_content: obj_attachment.description,
                 post_excerpt: caption
             };
     
             if ( display.linkUrl )
                 options.url = display.linkUrl;
     
             if ( 'image' === obj_attachment.type ) {
                 html = wp.media.string.image( display );
                 _.each({
                 align: 'align',
                 size:  'image-size',
                 alt:   'image_alt'
                 }, function( option, prop ) {
                 if ( display[ prop ] )
                     options[ option ] = display[ prop ];
                 });
             } else if ( 'video' === obj_attachment.type ) {
                 html = wp.media.string.video( display, obj_attachment );
             } else if ( 'audio' === obj_attachment.type ) {
                 html = wp.media.string.audio( display, obj_attachment );
             } else {
                 html = wp.media.string.link( display );
                 options.post_title = display.title;
             }
     
             //attach info to attachment.attributes object
             attachment.attributes['nonce'] = wp.media.view.settings.nonce.sendToEditor;
             attachment.attributes['attachment'] = options;
             attachment.attributes['html'] = html;
             attachment.attributes['post_id'] = wp.media.view.settings.post.id;
     
             //do what ever you like to use it
             console.log(attachment.attributes);
             console.log(attachment.attributes['attachment']);
             console.log(attachment.attributes['html']);
         });
     });
     
     //reset selection in popup, when open the popup
     frame.on('open',function() {
         var selection = frame.state('insert-image').get('selection');
     
         //remove all the selection first
         selection.each(function(image) {
             var attachment = wp.media.attachment( image.attributes.id );
             attachment.fetch();
             selection.remove( attachment ? [ attachment ] : [] );
         });
     
         //add back current selection, in here let us assume you attach all the [id] to <div id="my_file_group_field">...<input type="hidden" id="file_1" .../>...<input type="hidden" id="file_2" .../>
         jq("#my_file_group_field").find('input[type="hidden"]').each(function(){
              var input_id = jq(this);
             if( input_id.val() ){
                 attachment = wp.media.attachment( input_id.val() );
                 attachment.fetch();
                 selection.add( attachment ? [ attachment ] : [] );
             }
         });
     });
     
     //now open the popup
     frame.open();
     

Answer 2

I would like to add to ZAC's option 4 because when I used his code, the image src="" was missing.

Here is the fix

                if ( 'image' === obj_attachment.type ) {
                html = wp.media.string.image( display );
                _.each({
                align: 'align',
                size:  'image-size',
                alt:   'image_alt'
                }, function( option, prop ) {
                if ( display[ prop ] )
                    options[ option ] = display[ prop ];
                });
                html = wp.media.string.image( display, obj_attachment );
            }
