Getting "prompt aborted by user" javascript exception
提问by Bhagwat Gurle
I am getting "Components.Exception("prompt aborted by user", Cr.NS_ERROR_NOT_AVAILABLE)"exception when I am using "windows.location.href" in javasacript. My Code is:
当我在 javasacript 中使用“windows.location.href”时，我收到“Components.Exception(“prompt aborted by user”, Cr.NS_ERROR_NOT_AVAILABLE)”异常。我的代码是：
function checkCookie(){
var value = null;
var cookieName='UserDetailsCookie';
value=ReadCookie(cookieName);
if(value != null){
var url='<%=request.getContextPath()%>/jsp/admin.jsp';
window.location.href = url;
}
document.loginForm.userName.focus();
}
}
function ReadCookie(name)
{
name += '=';
var parts = document.cookie.split(/;\s*/);
for (var i = 0; i < parts.length; i++)
{
var part = parts[i];
if (part.indexOf(name) == 0)
return part.substring(name.length);
}
return null;
}
}
and I am calling this method on onLoad event of body
我在 body 的 onLoad 事件上调用这个方法
<body onLoad="javascript:checkCookie();">
In anyone knows why this exception throws please?
有谁知道为什么会抛出这个异常？

I'm not 100% sure, but I think this is due to the line
我不是 100% 确定，但我认为这是由于线路
document.loginForm.userName.focus();
because this will cancel the loading of your URL done with the window.location.href = 'xxx'.
因为这将取消使用 window.location.href = 'xxx' 完成的 URL 加载。
Anyway, in general there should NOT be any line of code after setting the location.href property.
无论如何，通常在设置 location.href 属性后不应该有任何代码行。
Hope that helps, I know it's old but I answered for moomoochoo since his comment isn't "that" old.
希望有帮助，我知道它很旧，但我回答了 moomoochoo，因为他的评论不是“那么”旧。
