javascript弹出警告链接点击

Question

我需要一个JavaScript'确定'/'取消'警告一旦我点击一个链接。

我有报警代码：

<script type="text/javascript"> 
<!-- 
var answer = confirm ("Please click on OK to continue.") 
if (!answer) 
window.location="http://www.continue.com" 
// --> 
</script> 

但我怎么做起来很点击某个链接时，这只奔跑？

Answer 1

只是令其功能，

<script type="text/javascript"> 
function AlertIt() { 
var answer = confirm ("Please click on OK to continue.") 
if (answer) 
window.location="http://www.continue.com"; 
} 
</script> 

<a href="javascript:AlertIt();">click me</a> 

Answer 2

为了做到这一点，你需要将处理程序附加到页面上的特定锚。对于像这样的操作，使用标准框架如jQuery要容易得多。例如，如果我有以下HTML

HTML：

<a id="theLink">Click Me</a> 

我可以使用下面的jQuery来装一个事件的具体环节。

// Use ready to ensure document is loaded before running javascript 
$(document).ready(function() { 

    // The '#theLink' portion is a selector which matches a DOM element 
    // with the id 'theLink' and .click registers a call back for the 
    // element being clicked on 
    $('#theLink').click(function (event) { 

    // This stops the link from actually being followed which is the 
    // default action 
    event.preventDefault(); 

    var answer confirm("Please click OK to continue"); 
    if (!answer) { 
     window.location="http://www.continue.com" 
    } 
    }); 

}); 

Answer 3

可以使用onclick属性，只是return false如果你不想继续;

<script type="text/javascript"> 
function confirm_alert(node) { 
    return confirm("Please click on OK to continue."); 
} 
</script> 
<a href="http://www.google.com" onclick="return confirm_alert(this);">Click Me</a> 

Answer 4

单线工作得很好：

<a href="http://example.com/" 
onclick="return confirm('Please click on OK to continue.');">click me</a> 

添加另一条线与同一页面上的其他链接工作太细：

<a href="http://stackoverflow.com/" 
onclick="return confirm('Click on another OK to continue.');">another link</a> 

Answer 5

function alert() { 
    var answer = confirm ("Please click on OK to continue.") ; 

    if(answer){ 
     window.location="url"; 
    } 
}
