JavaScript確實忽略了我的或陳述

Question

你好我有這種形式我想驗證，現在我寫了這個很好的小javascript/jquery組合，但我似乎卡住了這個特殊的如果聲明。

它在哪裏檢查名稱屬性，如果它包含「naam」。 如果我點擊並點擊它進行檢查，並且滿足默認值的條件，則將邊框設爲紅色。

現在我嘗試重新提交這個表單與更改的值，我鍵入我的名字到字段爲例。

它應該觸發其他並刪除紅色邊框或任何邊框。我在這裏錯過了什麼？

$(document).ready(function() { 

    function isValidEmailAddress(emailAddress) { 
    var pattern = new RegExp(/^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i);

     } 


     //alert("Empty Fields!!"); 
     } 
     i=i+1; 

    }); 

    }); 
}); 

形式：

<input type="text" name="naam" value="* Naam" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;"> 
<input type="text" name="bedrijfsnaam" value="Bedrijfsnaam" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;">

Answer 2

這是因爲.VAL（）==這個默認值

如果（$（本）第一檢查。 defaultValue）{

你沒有做任何事情在這個if語句的else語句中。 因此，當填寫與默認值不同的東西時，將不會執行任何操作，並且紅色邊框將永遠不會被刪除。
