我想拿一根绳子
var a = "http://example.com/aa/bb/"
然后把它加工成一个物体
a.hostname == "example.com"
and
a.pathname == "/aa/bb"

第一个答案的简单破解
var getLocation = function(href=window.location.href) {
var l = document.createElement("a");
l.href = href;
return l;
};
即使没有参数,也可以使用它来计算当前的主机名 getLocation()。Hostname将给出当前主机名
其他回答
var loc = window.location; // => "http://example.com:3000/pathname/?search=test#hash"
返回当前turl。
如果你想传递你自己的字符串作为url(在IE11中不工作):
var loc = new URL("http://example.com:3000/pathname/?search=test#hash")
然后你可以这样解析它:
loc.protocol; // => "http:"
loc.host; // => "example.com:3000"
loc.hostname; // => "example.com"
loc.port; // => "3000"
loc.pathname; // => "/pathname/"
loc.hash; // => "#hash"
loc.search; // => "?search=test"
试试这个:
函数getUrlPath (str) { //fakepath当url没有路径 var fakepath = "/FakPath"; Var url = str+fakepath; Var reg = /.+?\:\/\/.+?(\/.+?)(?:#|\?|$)/; Var output = reg.exec(url); //检查"output" != null 返回(输出)?输出[1].replace(fakepath,""): fakepath; } Var myurl = "https://stackoverflow.com/questions/736513/"; const path = getUrlPath(myurl); Console.log (path); //output: /questions/736513/
怎么样?
'https://stackoverflow.com/questions/736513/how-do-i-parse-a-url-into-hostname-and-path-in-javascript'.split('//').pop() .split('/')[0]
结果:
“stackoverflow.com”
以下是我从https://gist.github.com/1847816复制的一个版本,但经过重写,以便于阅读和调试。将锚数据的值复制到另一个名为“result”的变量的目的是因为锚数据相当长,因此将有限数量的值复制到结果将有助于简化结果。
/**
* See: https://gist.github.com/1847816
* Parse a URI, returning an object similar to Location
* Usage: var uri = parseUri("hello?search#hash")
*/
function parseUri(url) {
var result = {};
var anchor = document.createElement('a');
anchor.href = url;
var keys = 'protocol hostname host pathname port search hash href'.split(' ');
for (var keyIndex in keys) {
var currentKey = keys[keyIndex];
result[currentKey] = anchor[currentKey];
}
result.toString = function() { return anchor.href; };
result.requestUri = result.pathname + result.search;
return result;
}
freddiefujiwara的答案很好,但我也需要在ie中支持相对url。我想出了以下解决方案:
function getLocation(href) {
var location = document.createElement("a");
location.href = href;
// IE doesn't populate all link properties when setting .href with a relative URL,
// however .href will return an absolute URL which then can be used on itself
// to populate these additional fields.
if (location.host == "") {
location.href = location.href;
}
return location;
};
现在使用它来获得所需的属性:
var a = getLocation('http://example.com/aa/bb/');
document.write(a.hostname);
document.write(a.pathname);
例子:
function getLocation(href) { var location = document.createElement("a"); location.href = href; // IE doesn't populate all link properties when setting .href with a relative URL, // however .href will return an absolute URL which then can be used on itself // to populate these additional fields. if (location.host == "") { location.href = location.href; } return location; }; var urlToParse = 'http://example.com/aa/bb/', a = getLocation(urlToParse); document.write('Absolute URL: ' + urlToParse); document.write('<br />'); document.write('Hostname: ' + a.hostname); document.write('<br />'); document.write('Pathname: ' + a.pathname);
