未捕獲的語法錯誤：意外的標識符錯誤

Question

每當我嘗試點擊以下鏈接時，我都會在Chrome開發人員工具控制檯中看到（未捕獲的SyntaxError：意外的標識符錯誤）。我的代碼中看不到任何錯誤，所以有人可以檢查它並告訴我我在這裏錯過了什麼嗎？

<a href="javascript:warningMsg('Are you sure you want to delete this User? This step can't be undone!','/invoicing/users/','2','delete-user')">Delete User</a> 

下面是warningMsg功能，遺憾的是它並不甚至稱，但包含它包含在HTML頁面上面的鏈接.js文件：

function warningMsg(warningMsgContent, url, id, actionType){ 
alert(url+actionType+"?id="+id); 
window.location.assign(url+actionType+"/?id="+id); 
} 

注：我試圖逃離「在不能這樣做它可以\'t，但我得到了同樣的錯誤

感謝您的時間和精力

Answer 1

這是因爲在這個詞的'的‘不能’ - 它的原因你的報價是不匹配的。

'Are you sure you want to delete this User? This step can't be undone!' 
^              ^  ^

要解決這個問題，你需要要麼逃避在' 「不能」 用一個反斜槓：

'Are you sure you want to delete this User? This step can\'t be undone!' 

Answer 2

嘗試This step can\'t be undone!

，而不是This step can't be undone!

Answer 3

在window.location.assign(url+actionType+"/?id="+id);您會得到類似於以下的結果：

/invoicing/users/?id=2 

由於此：url+actionType+"/?id="+id。

當然，除了引用別人提到的引用轉義問題外，這也是。

Answer 4

您在can't有未轉義的單引號。它應該是can\t。

<a href="javascript:warningMsg('Are you sure you want to delete this User? This step can\'t be undone!','/invoicing/users/','2','delete-user')">Delete User</a> 

但是，不應該使用內聯js（javascript在你的html中）（除非用於快速測試目的）。閱讀其中的一些結果：Why is inline js bad?

取而代之的是，將javascript附加到javascript！

<a id="delete-user">Delete User</a> 

的JavaScript：

var d = document.getElementById('delete-user'); 
d.addEventListener('click', function() { 
    warningMsg(
    "Are you sure you want to delete this User? This step can't be undone!", 
    '/invoicing/users/', 
    '2', 
    'delete-user' 
); 
}); 

Here's a live demo you can mess with.

Answer 5

取代：

<a href="javascript:warningMsg('Are you sure you want to delete this User? This step can't be undone!','/invoicing/users/','2','delete-user')">Delete User</a> 

到：

<a href="javascript:warningMsg('Are you sure you want to delete this User? This step can\'t be undone!','/invoicing/users/','2','delete-user')">Delete User</a> 

反正，我通常建議你使用事件處理程序的代替內嵌代碼（的onclick = ...）（逃避這個詞的'可以不需要）：

HTML：

<a id="btn_delete" href="#">Delete user</a> 

的javascript：

document.getElementById('btn_delete').addEventListener('click', function() { 
    warningMsg('Are you sure you want to delete this User? This step can\'t be undone!','/invoicing/users/','2','delete-user'); 
}); 

希望有幫助。
