#"包含了一个位置信息

默认的锚点是#top 也就是网页的上端

而javascript:void(0)  仅仅表示一个死链接

这就是为什么有的时候页面很长浏览链接明明是#可是跳动到了页首

而javascript:void(0) 则不是如此

所以调用脚本的时候最好用void(0)

或者

打开新窗口链接的几种办法

1.window.open('url')

2.用自定义函数

        <script><br>        function openWin(tag,obj)<br>        {<br>            obj.target="_blank";<br>            obj.href = "Web/Substation/Substation.aspx?stationno="+tag;<br>            obj.click();<br>        }<br>        </script>

LINK_TEST

window.location.href=""

如果是个# ,就会出现跳到顶部的情况,个人收藏的几种解决方法:

慎用JavaScript:void(0)

 

JavaScript中void是一个操作符,该操作符指定要计算一个表达式但是不返回值。
void 操作符用法格式如下:
1. javascript:void (expression)
2. javascript:void expression
expression是一个要计算的 JavaScript 标准的表达式。表达式外侧的圆括号是可选的,但是写上去是一个好习惯。我们可以使用 void 操作符指定超级链接。表达式会被计算但是不会在当前文档处装入任何内容。面的代码创建了一个超级链接,当用户点击以后不会发生任何事。当用户点击链接时,void(0) 计算为 0,但在 JavaScript 上没有任何效果。

单击此处什么也不会发生

In other words, if you want to perform certain processing without refreshing the page as a whole, you can use void(0), but if you need to refresh the page, you need to be careful.

In fact, we can use . This sentence will perform a submit operation. So under what circumstances is void(0) used more often? Without refresh, of course it is Ajax. If you look at the Ajax web page, you will generally see a lot of void(0), :), so when using void(0) ), it’s best to think about whether this page needs to be refreshed as a whole.
