我如何在javascript中解析URL到主机名和路径?

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"

当前回答

使用https://www.npmjs.com/package/uri-parse-lib进行此操作

var t = parserURI("http://user:pass@example.com:8080/directory/file.ext?query=1&next=4&sed=5#anchor");

其他回答

对于那些正在寻找在IE, Firefox和Chrome中工作的现代解决方案的人:

这些使用超链接元素的解决方案都不会在chrome中起同样的作用。如果你传递一个无效(或空白)的url给chrome，它总是会返回脚本被调用的主机。所以在IE中你会得到空白，而在Chrome中你会得到localhost(或其他什么)。

如果你试图看着推荐人，这是骗人的。你需要确保你返回的主机在原始url中，以处理这个问题:

    function getHostNameFromUrl(url) {
        // <summary>Parses the domain/host from a given url.</summary>
        var a = document.createElement("a");
        a.href = url;

        // Handle chrome which will default to domain where script is called from if invalid
        return url.indexOf(a.hostname) != -1 ? a.hostname : '';
    }

AngularJS的方法在这里:http://jsfiddle.net/PT5BG/4/

<!DOCTYPE html>
<html>
<head>
    <title>Parse URL using AngularJS</title>
</head>
<body ng-app ng-controller="AppCtrl" ng-init="init()">

<h3>Parse URL using AngularJS</h3>

url: <input type="text" ng-model="url" value="" style="width:780px;">

<ul>
    <li>href = {{parser.href}}</li>
    <li>protocol = {{parser.protocol}}</li>
    <li>host = {{parser.host}}</li>
    <li>hostname = {{parser.hostname}}</li>
    <li>port = {{parser.port}}</li>
    <li>pathname = {{parser.pathname}}</li>
    <li>hash = {{parser.hash}}</li>
    <li>search = {{parser.search}}</li>
</ul>

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.min.js"></script>

<script>
function AppCtrl($scope) {

    $scope.$watch('url', function() {
        $scope.parser.href = $scope.url;
    });

    $scope.init = function() {
        $scope.parser = document.createElement('a');
        $scope.url = window.location;
    }

}
</script>

</body>
</html>

今天我遇到了这个问题，我发现:URL - MDN Web api

var url = new URL("http://test.example.com/dir/subdir/file.html#hash");

这返回:

{ hash:"#hash", host:"test.example.com", hostname:"test.example.com", href:"http://test.example.com/dir/subdir/file.html#hash", origin:"http://test.example.com", password:"", pathname:"/dir/subdir/file.html", port:"", protocol:"http:", search: "", username: "" }

希望我的第一篇文章能帮助到你!

在这里找到:https://gist.github.com/jlong/2428561

var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";

parser.protocol; // => "http:"
parser.host;     // => "example.com:3000"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.hash;     // => "#hash"
parser.search;   // => "?search=test"
parser.origin;   // => "http://example.com:3000"

在acdcjunior解决方案上扩展了“searchParam”功能模仿URL对象，增加了“searchParam”来解析查询字符串适用于IE 6、7、8、9、10、11

用法- (JSFiddle Link)

// USAGE:
var myUrl = new ParsedUrl("http://www.example.com/path?var1=123&var2=abc#fragment");
console.log(myUrl);
console.log(myUrl.searchParam('var1'));
console.log(myUrl.searchParam('var2'));

输出- (JSFiddle链接)

{
  hash: "#fragment",
  host: "www.example.com:8080",
  hostname: "www.example.com",
  href: "http://www.example.com:8080/path?var1=123&amp;var2=abc#fragment",
  pathname: "/path",
  port: "80",
  protocol: "http:",
  search: "?var1=123&amp;var2=abc"
}

"123"
"abc"

CODE - (JSFiddle Link)

function ParsedUrl(url) {
    var parser = document.createElement("a");
    parser.href = url;
    
    // IE 8 and 9 dont load the attributes "protocol" and "host" in case the source URL
    // is just a pathname, that is, "/example" and not "http://www.example.com/example".
    parser.href = parser.href;
    
    // IE 7 and 6 wont load "protocol" and "host" even with the above workaround,
    // so we take the protocol/host from window.location and place them manually
    if (parser.host === "") {
        var newProtocolAndHost = window.location.protocol + "//" + window.location.host;
        if (url.charAt(1) === "/") {
            parser.href = newProtocolAndHost + url;
        } else {
            // the regex gets everything up to the last "/"
            // /path/takesEverythingUpToAndIncludingTheLastForwardSlash/thisIsIgnored
            // "/" is inserted before because IE takes it of from pathname
            var currentFolder = ("/"+parser.pathname).match(/.*\//)[0];
            parser.href = newProtocolAndHost + currentFolder + url;
        }
    }
    
    // copies all the properties to this object
    var properties = ['host', 'hostname', 'hash', 'href', 'port', 'protocol', 'search'];
    for (var i = 0, n = properties.length; i < n; i++) {
      this[properties[i]] = parser[properties[i]];
    }
    
    // pathname is special because IE takes the "/" of the starting of pathname
    this.pathname = (parser.pathname.charAt(0) !== "/" ? "/" : "") + parser.pathname;
  
  //search Params
  this.searchParam =  function(variable) {
    var query = (this.search.indexOf('?') === 0) ? this.search.substr(1) : this.search;
    var vars = query.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        if (decodeURIComponent(pair[0]) == variable) {
            return decodeURIComponent(pair[1]);
        }
    }
    console.log('Query variable %s not found', variable);
    return '';
    };
}
