建立一個標籤

創建標籤 " " 用於輸入

				
					{"blocks":"<xml xmlns=\"https://developers.google.com/blockly/xml\"><block type=\"Control_createLabel\"><value name=\"labelText\"><shadow type=\"text\"><field name=\"TEXT\"/></shadow></value></block></xml>"}

參數:

          • 顯示設定:字串
          • 螢幕項目(非輸入控制)

輸出: 螢幕項目
