remove url parameters with javascript or jquery

问题:

I am trying to use the youtube data api to generate a video playlist.

However, the video urls require a format of:

youtube.com/watch?v=3sZOD3xKL0Y

but what the api generates is:

youtube.com/watch?v=3sZOD3xKL0Y&feature=youtube_gdata

So what I need to do is be able to select everything after and including the ampersand(&) and remove it from the url.

Any way to do this with javascript and some sort of regular expression?

回答1:

Simple:

var new_url = old_url.substring(0, old_url.indexOf('?'));

Modified: this will remove all parameters or fragments from url

var oldURL = [YOUR_URL_TO_REMOVE_PARAMS]
var index = 0;
var newURL = oldURL;
index = oldURL.indexOf('?');
if(index == -1){
    index = oldURL.indexOf('#');
}
if(index != -1){
    newURL = oldURL.substring(0, index);
}

回答2:

What am I missing?

Why not:

url.split('?')[0] 

回答3:

Hmm... Looking for better way... here it is

var onlyUrl = window.location.href.replace(window.location.search,'');

Example: http://jsfiddle.net/SjrqF/

var url = 'youtube.com/watch?v=3sZOD3xKL0Y&feature=youtube_gdata';

url = url.slice( 0, url.indexOf('&') );

or:

Example: http://jsfiddle.net/SjrqF/1/

var url = 'youtube.com/watch?v=3sZOD3xKL0Y&feature=youtube_gdata';

url = url.split( '&' )[0];

//user113716 code is working but i altered as below. it will work if your URL contain "?" mark or not
//replace URL in browser
if(window.location.href.indexOf("?") > -1) {
    var newUrl = refineUrl();
    window.history.pushState("object or string", "Title", "/"+newUrl );
}

function refineUrl()
{
    //get full url
    var url = window.location.href;
    //get url after/  
    var value = url = url.slice( 0, url.indexOf('?') );
    //get the part after before ?
    value  = value.replace('@System.Web.Configuration.WebConfigurationManager.AppSettings["BaseURL"]','');  
    return value;     
}

回答6:

Use this function:

var getCleanUrl = function(url) {
  return url.replace(/#.*$/, '').replace(/\?.*$/, '');
};

// get rid of hash and params
console.log(getCleanUrl('https://sidanmor.com/?firstname=idan&lastname=mor'));

If you want all the href parts, use this:

var url = document.createElement('a');
url.href = 'https://developer.mozilla.org/en-US/search?q=URL#search-results-close-container';

console.log(url.href); // https://developer.mozilla.org/en-US/search?q=URL#search-results-close-container
console.log(url.protocol); // https:
console.log(url.host); // developer.mozilla.org
console.log(url.hostname); // developer.mozilla.org
console.log(url.port); // (blank - https assumes port 443)
console.log(url.pathname); // /en-US/search
console.log(url.search); // ?q=URL
console.log(url.hash); // #search-results-close-container
console.log(url.origin); // https://developer.mozilla.org

You could use a RegEx to match the value of v and build the URL yourself since you know the URL is youtube.com/watch?v=...

http://jsfiddle.net/akURz/

var url = 'http://youtube.com/watch?v=3sZOD3xKL0Y';
alert(url.match(/v\=([a-z0-9]+)/i));

Well, I am using this:

stripUrl(urlToStrip){
        let stripped = urlToStrip.split('?')[0];
        stripped = stripped.split('&')[0];
        stripped = stripped.split('#')[0];
        return stripped;
    }

or:

    stripUrl(urlToStrip){
        return urlToStrip.split('?')[0].split('&')[0].split('#')[0];
    }

回答9:

This worked for me:

window.location.replace(window.location.pathname)

回答10:

For example we have:

example.com/list/search?q=Somethink

And you need use variable url like this by window.location.href:

example.com/list/edit

From url:

example.com/list/search?q=Somethink
example.com/list/

var url = (window.location.href);
    url = url.split('/search')[0];
    url = (url + '/edit');

This is simple solution:-)
