你指的是禁用默认事件看
<a href="baidu.com">百度</a>1.jQuery 阻止默认事件
$("a").click(function( event ) {
event.preventDefault() // 阻止默认事件
event.stopPropagation() // 阻止冒泡
})
2.javascript
var elem = document.getElementByTagName("a")
elem.addEventListener("click",function(event){
event.preventDefault() // 阻止默认事件
event.stopPropagation() // 阻止冒泡
},false)
说明:
preventDefault() // 阻止默认事件
stopPropagation() // 阻止冒泡
return false // 既阻止默认事件 也阻止冒泡

在html中要使a标签不可用,需要在onclick时返回false即可,具体代码如下所示:1、通过设置onclick属性使其不可用
<a href="http://mail.163.com" onclick="return false">HTML控制链接不可用</a>
2、通过js动态控制使其不可用
<a id="link" href="http://mail.163.com" onclick="return false">JS控制链接不可用</a>
<script>
document.getElementById("link").onclick=function(){return false}
</script>
