瀏覽器后台報錯，Vue組件的坑：property or method " " is not defined on the instance but referenced during render.Make sure that this property in reactive,either in the data,or for class-based

頁面那個很正常，但是瀏覽器后天一直報錯：property or method "組件名 " is not defined on the instance but referenced during render.Make sure that this property in reactive,either in the data,or for class-based 

以前也遇到過，這個是：有個方法或者屬性在數據data里沒定義，無法實現數據的響應式的樣式，提供觀察發現父組件里有個v-model“組件名”，確實在data里沒定義屬性，初始值給個

因為v-models=屬性名“”，是Vue雙向綁定，必須現在data里定義個初始值，在發福利改變值或狀態：所以

data（）{

v-model的綁定屬性：false；// 可以了

}
