html中的a标签用js来实现页面跳转的功能（php分页时做的页面跳转）

2012-03-02 13:09 1181 查看

当php在做分页时，有时候会要想做个指定跳转到某页的功能，而要跳转到某页就要涉及到js。因为必须通过js来找到用户输入的是什么，是哪一页。

所以，如果你用的是一个图片来做点击实现跳转的话，那么就可以通过在图片外面包裹一个a标签来实现点击并获取输入值。

现在问题是这样写：

<a href="" onclick=“page（）”>那么浏览器中是不能实现跳转的呢。因为page（）的js方法中不管你怎么写Windows.location.href="www.zhishuibei.com";都不能跳转，原因是a标签的href里面是空的，浏览器执行了这个地方。那么怎么办呢？

其实写程序久了就容易忘了html里面的一些常识。呵呵。那么问题怎么解决呢？看下面：

<a href="javascript:page();">现在去试试呢。或者：

<a href="javascript:;" onclick="page()">

也去试试呢。没有浏览器兼容的问题吧。呵呵。就这么简单。只是因为忘了一些HTML常识而已。

下面是我的页面源码，共享出来给大家：
