我有以下网址:

其中bi
是特定图书的标识符。
如何从链接中提取图书ID?
谢谢!

您可以使用此正则表达式:
var address = "http://www.abebooks.com/servlet/BookDetailsPL?bi=1325819827&...";
var bi = /[\?&]bi=(\d+)/.exec(address)[1]
alert(bi)

function getBookId()
{
var query = document.location.split("?")[1];
var values = query.split("&");
for(var i = 0; i < values.length; i++)
{
a = values[i].split("=");
if(a[0] === "bi")
return a[1];
}
//some error occurred
return null;
}

您可以通过正则表达式(和分组)提取图书ID(假设只是数字)。
var s = "http://www.abebooks.com/servlet/BookDetailsPL?\
bi=1325819827&searchurl=an%3DLofting%252C%2BHugh.\
%26ds%3D30%26sortby%3D13%26tn%3DDOCTOR%2BDOLITTLE\
%2527S%2BGARDEN."
var re = /bi=([0-9]+)&/; // or equally: /bi=(\d+)&/
var match = re.exec(s);
match[1]; // => contains 1325819827

address.split( “BI =”)[1] .split( “&安培;”)[0]
答案 4 :(得分:0)
试试这个
var bookId
var matcher = location.search.match(/(?:[?&]bi=([^&]+))/); // Assuming window.location
if (null !== matcher) {
bookId = matcher[1];
}

我曾经遇到过同样的问题 我创建了一个小功能来帮助我。不知道它在哪里,但我设法重新创建它:
function get(item,url) {
if (url == undefined)
url = window.location.href;
var itemlen = item.length
var items = url.split('?')[1].split('&');
for (var i = 0, len = items.length;i<len;i++) {
if (items[i].substr(0,itemlen) == item)
return items[i].split('=')[1];
}
return null;
}
所以你会像使用它一样:
get('bi');
如果您提供的网址是您当前的网址,如果不是,您可以这样做:
get('bi','http://www.abebooks.com/servlet/BookDetailsPL?bi=1325819827&searchurl=an%3DLofting%252C%2BHugh.%26ds%3D30%26sortby%3D13%26tn%3DDOCTOR%2BDOLITTLE%2527S%2BGARDEN.')
希望我没有留下任何错误:)
