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
