javascript将url中的某些参数替换的需求:
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('http://www.cuoxin.com/')
};
}
用法：
var myURL = parseURL('http://www.***.com/default.aspx?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; // = '/dir/index.html'
myURL.segments; // = Array = ['dir', 'index.html']
myURL.port; // = '8080'
myURL.protocol; // = 'http'
myURL.source; // = 'http://www.***.com
取得URL的参数，以对象形式返回！
var getParam = function(path){
var result = {},param = /([^?=&]+)=([^&]+)/ig,match;
while((match = param.exec(path)) != null){
result[match[1]] = match[2];
}
return result;
}
Object.keys = Object.keys || function(obj){
var result = [];
for(var i in obj){
if(obj.hasOwnProperty(i)){
result.push(i)
}
}
return result;
}
var path = "***.com/f?ct=318767104&tn=baiduKeywordSearch&sc=1&pn=0&rn=50&lm=4&rs4=2&rs3=2&word=%D0%C2%BE%D3%D5%D1%C4%CB&frs=jpq";
var r = getParam(path);
alert(Object.keys(r))//ct,tn,sc,pn,rn,lm,rs4,rs3,word,frs
