javascript parseUrl函数(来自国外的获取网址url参数)

复制代码 代码如下:

function parseURL(url) {
var a = document.createElement('a');
a.href = url;
return {
source: url,
protocol: a.protocol.replace(':',''),
host: a.hostname,
port: a.port,
query: a.search,
params: (function(){
var ret = {},
seg = a.search.replace(/^\?/,'').split('&'),
len = seg.length, i = 0, s;
for (;i<len;i++) {
if (!seg[i]) { continue; }
s = seg[i].split('=');
ret[s[0]] = s[1];
}
return ret;
})(),
file: (a.pathname.match(/\/([^\/?#]+)$/i) || [,''])[1],
hash: a.hash.replace('#',''),
path: a.pathname.replace(/^([^\/])/,'/$1'),
relative: (a.href.match(/tps?:\/\/[^\/]+(.+)/) || [,''])[1],
segments: a.pathname.replace(/^\//,'').split('/')
};
}

复制代码 代码如下:

var myURL = parseURL('http://abc.com:8080https://img.qb5200.com/download-x/dir/index.html?id=255&m=hello#top');
myURL.file; // = 'index.html'
myURL.hash; // = 'top'
myURL.host; // = 'abc.com'
myURL.query; // = '?id=255&m=hello'
myURL.params; // = Object = { id: 255, m: hello }
myURL.path; // = 'https://img.qb5200.com/download-x/dir/index.html'
myURL.segments; // = Array = ['dir', 'index.html']
myURL.port; // = '8080'
myURL.protocol; // = 'http'
myURL.source; // = 'http://abc.com:8080https://img.qb5200.com/download-x/dir/index.html?id=255&m=hello#top'
