用另一个链接替换默认链接(Replace a default link with another link)

用另一个链接替换默认链接(Replace a default link with another link)

我想用另一个链接改变现有链接的链接属性href 。 我怎样才能做到这一点？

链接在这里：

<a href="defaultlink.php?go=no">See more</a><a href="defaultlink.php?go=yes">See more</a><a href="defaultlink.php?go=why">See more</a>

我尝试了以下，但它不起作用：

var links = document.getElementsByTagName('a'); var len = links.replace; for(var i=0; i<replace; i++){ links[i].href = "newlink.php?+BLABLABAL"; }

I want change the link attribute href of an existing link with another link using JavaScript. How can I do this?

Here is the link:

<a href="defaultlink.php?go=no">See more</a><a href="defaultlink.php?go=yes">See more</a><a href="defaultlink.php?go=why">See more</a>

I have tried the following but it doesn't work:

var links = document.getElementsByTagName('a'); var len = links.replace; for(var i=0; i<replace; i++){ links[i].href = "newlink.php?+BLABLABAL"; }

最满意答案

替换links.replace by links.length ，因为您正在遍历链接数组。

工作代码：

// This is an array of links var links = document.getElementsByTagName('a'); // The length of the array var len = links.length; // Iterate over the array for(var i = 0; i < len; i++){ links[i].href = "https://twitter.com"; }

Replace links.replace by links.length, since you are iterating over the links array.

Working code:

// This is an array of links var links = document.getElementsByTagName('a'); // The length of the array var len = links.length; // Iterate over the array for(var i = 0; i < len; i++){ links[i].href = "https://twitter.com"; }
