Question

将CONTENT中的网址转换为可点击并缩短。

例如：

转换内容

Balabala The link is http://www.google.com/?aaaaabefaaaaaaaaaaaafeeafaeff3asefffffffffff

到

Balabala The link is <a href=http://www.google.com/?aaaaabefaaaaaaaaaaaafeeafaeff3asefffffffffff>http://www.google.com/?aa...</a>

Answer 1

这样的事情可能有所帮助：

<div id='result'>
</div>
<script>
var content = "The link is http://www.google.com/?q=hello visit it!";
var result = content.replace(/(http:\/\/(www\.)?([^(\s)]+))/, "<a href='$1'>$3</a>");
document.getElementById('result').innerHTML = result;
</script>

Answer 2

这是一个用锚点替换字符串中的任何URL的函数：

function linkify(str){
    var url = 'http://www.google.com/?aaaaabefaaaaaaaaaaaafeeafaeff3asefffffffffff';
    return str.replace(/https?\:\/\/\S+/, function(url){
        var shortUrl = url.substring(0, 20) + '...';
        return shortUrl.link(url)
    })
}

linkify("Balabala The link is http://www.google.com/?aaaaabefaaaaaaaaaaaafeeafaeff3asefffffffffff")
// "Balabala The link is <a href="http://www.google.com/?aaaaabefaaaaaaaaaaaafeeafaeff3asefffffffffff">http://www.google.com/?aaaaabe...</a>"

“cut”长度可以作为第二个参数传递。

Answer 3

类似的东西：

len = 15; //set how long of a string you would like to show

url = "http://www.google.com/?aaaaabefaaaaaaaaaaaafeeafaeff3asefffffffffff";

//if the original url is smaller than or equal to the length than do nothing
//otherwise take the len number of chars and append ... after
shorturl = (url.length <= len) ? url : url.substr(0,len) + "..."; 

link = "<a href='" + url + "'>" + shorturl + "</a>";
