点击链接后,我需要一个javascript'确定'/'取消'提醒。
我有警报代码:
<script type="text/javascript">
<!--
var answer = confirm ("Please click on OK to continue.")
if (!answer)
window.location="http://www.continue.com"
// -->
</script>
但是我如何才能这样做只在点击某个链接时运行?

如果您不想继续,可以使用onclick
属性,return false
;
<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>

让它发挥作用,
<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>

单行工作正常:
<a href="http://example.com/"
onclick="return confirm('Please click on OK to continue.');">click me</a>
在同一页面上添加另一个具有不同链接的行也可以正常工作:
<a href="http://stackoverflow.com/"
onclick="return confirm('Click on another OK to continue.');">another link</a>

为此,您需要将处理程序附加到页面上的特定锚点。对于这样的操作,使用像jQuery这样的标准框架要容易得多。例如,如果我有以下HTML
HTML:
<a id="theLink">Click Me</a>
我可以使用以下jQuery将事件连接到该特定链接。
// 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"
}
});
});
