完美解決 Cannot read property 'length' of undefined
easyUI 前端
easyui中datagrid執行loadData方法出現以下異常java
此時這裏的rows==undefined，因此報錯了，能夠在for循環前判斷rows是否大於0 ，但更好的辦法是在後臺解決，讓返回的json數據裏面包含rows屬性，設置其默認值爲0就好json
解決辦法：ui
這個問題迷惑了我兩三個小時，想一想均可怕。雖然是底層js報錯，可是隻要知道緣由，跟着具體緣由改改就行了。其實也沒那麼難，畢竟我是搞java的，今天老大讓我改前端，哎，心疼本身三秒鐘......blog
