Create a block from Context menu

[Julia]

Hi!

I use Blockly v.7.20211209

How can I add a block to workspace by clicking a context menu option?

I tried this: 

Blockly.Blocks['some_block'] = {

    ... 

    customContextMenu(options) {

        const option = {

            enabled: true,

            callback() {

                Blockly.serialization.blocks.append({

                    'type': 'text',

                    'fields': { 'TEXT': 'Now there is a block' }

                })

            },

        }

        const name = this.getFieldValue('NAME')

        option.text = Blockly.Msg.PROCEDURES_CREATE_DO.replace('%1', name)

        options.push(option)

     }

}

But it didn't work.

Actually,  by pressing the context menu button I need to add a block for the function with the ability to enter parameters.

In some previous version we used something like goog.dom.createDom('field', null, name)

Hi Julia,

 

How can I add a block to workspace by clicking a context menu option?

I tried this: 

Blockly.Blocks['some_block'] = {

    ... 

    customContextMenu(options) {

        const option = {

            enabled: true,

            callback() {

                Blockly.serialization.blocks.append({

                    'type': 'text',

                    'fields': { 'TEXT': 'Now there is a block' }

                })

It looks like you have supplied only one argument to append(); it has a second required argument which is the workspace you want to append the block to.

            },

        }

        const name = this.getFieldValue('NAME')

        option.text = Blockly.Msg.PROCEDURES_CREATE_DO.replace('%1', name)

        options.push(option)

     }

}

But it didn't work.

 Could you be a bit more specific about what you mean by "it didn't work"?  Were there some error messages in the console, for example?

Actually,  by pressing the context menu button I need to add a block for the function with the ability to enter parameters.

Then you will need to create a block with type: 'procedures_callnoreturn' (rather than type: 'text' as given in your example code).

In some previous version we used something like goog.dom.createDom('field', null, name)

I'm not sure what that would have done or how it could possibly have worked to add blocks to the workspace!

Best wishes,

Christopher

Hi Christopher!

Thanks for the answer. I'll try to figure it out some more.
