JQuery驗證插件errorPlacement在需要字符串時傳遞錯誤對象

Question

我遇到了類似的問題。不應該「錯誤」是一個錯誤字符串？當我提醒錯誤時它是一個對象（[對象對象]），當我把「errorPlacement」塊取出時，它工作正常，我試着把errorPlacement塊放在最後，當我改變這樣的第6行： element .closest（「div」）。append（「test message」）; I do GET「test message」string in the form without error。所以問題是「error」是一個對象而不是字符串。問題的插件 我使用jQuery驗證插件1.7和jQuery 1.6ish

$("#student-set-form").validate({ 
     errorPlacement: function(error, element) {     
      console.log(error); 
      alert(error); 
      element.closest("div").append(error); 
     },

報價OP：

「不應該 「錯誤」 是一個錯誤的字符串時？我警告錯誤它是一個 對象（[object Object]）。「

不，它不應該是一個字符串。這的確是一個對象，它看起來是這樣的......

<label for="myfield" class="error">This field is required</label> 

如果你想提取從error對象的字符串，使用jQuery .text() method。

這會給你一個包含錯誤消息的字符串：

error.text() 

否則，目前還不清楚你與你的代碼有什麼問題。
