Dashboard TextInput

[plainpylut]

I just started using Node-Red. I created a dashboard with text input. What is the best way to clear out msg.payload so the 'previous' input string is deleted?

New user! Unable to upload my flow; Sorry!

Thanks

To clear text input, send empty array

[{"id":"c162161.a3a32e8","type":"ui_button","z":"3dd56201.af994e","name":"","group":"5029d507.0459cc","order":1,"width":0,"height":0,"passthru":false,"label":"clear","tooltip":"","color":"","bgcolor":"","icon":"","payload":" []","payloadType":"json","topic":"","x":200,"y":130,"wires":[["f5ae66f8.419758"]]},{"id":"a5b23993.e20938","type":"debug","z":"3dd56201.af994e","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":520,"y":130,"wires":[]},{"id":"f5ae66f8.419758","type":"ui_text_input","z":"3dd56201.af994e","name":"Input Text","label":"","tooltip":"","group":"5029d507.0459cc","order":1,"width":"","height":"","passthru":false,"mode":"text","delay":"10","topic":"","x":350,"y":130,"wires":[["a5b23993.e20938"]]},{"id":"5029d507.0459cc","type":"ui_group","z":"","name":"flowtest","tab":"d7adc994.2273a8","order":1,"disp":true,"width":"6","collapse":false},{"id":"d7adc994.2273a8","type":"ui_tab","z":"","name":"Widgets","icon":"dashboard","order":1,"disabled":false,"hidden":false}]

Also you probably need to untick msg pass trough option.
