How to refresh a page with jQuery by passing a parameter to URL

I am refreshing my page using jQuery:

location.reload();

This is working great but I want to refresh the same page by passing a para开发者_JAVA技巧meter to URL.

How can I do this by using jQuery?

Ex:

If my url is www.myweb.com, I want to refresh this by passing a parameter like this

  www.myweb.com?single

Thank you

You should be able to accomplish this by using location.href

if(window.location.hostname == "www.myweb.com")
   window.location.href += "?single";

I would use REGEX with .replace like this:

window.location.href = window.location.href.replace( /[\?#].*|$/, "?single" );

You can use Javascript URLSearchParams.

var url = new URL(window.location.href);
url.searchParams.set('single','');
window.location.href = url.href;

[UPDATE]: If IE support is a need, check this thread:

SCRIPT5009: 'URLSearchParams' is undefined in IE 11

Thanks @john-m to talk about the IE support

Concision counts: I prefer window.location = "?single"; or window.location += "?single";

if window.location.hash is empty, you cant assign to location.href a new value without using a correct function (at least tested in chrome).

try the window.location.replace:

if (!window.location.hash) 
    {
        window.location.replace(window.location.href + "?single")
    }

You could simply have just done:

var varAppend = "?single";
window.location.href = window.location.href.replace(".com",".com" + varAppend);

Unlike the other answers provided, there is no needless conditional check. If you design your project properly, you'll let the interface make the decision making and calling that statement whenever an event has been triggered.

Since there will only be one ".com" in your url, it will just replace .com with .com?single. I just added varAppend just in case you want to make it easier to modify the code in the future with different kinds of url variables.

One other note: The .replace works by adding to the href since href returns a string containing the full url address information.

Click these links to see these more flexible and robust solutions. They're answers to a similar question:

• With jQuery and the query plug-in: window.location.search = jQuery.query.set('single', true);
• Without jQuery: Use parse and stringify on window.location.search

These allow you to programmatically set the parameter, and, unlike the other hacks suggested for this question, won't break for URLs that already have a parameter, or if something else isn't quite what you thought might happen.

var singleText = "single";
var s = window.location.search;

if (s.indexOf(singleText) == -1) {
    window.location.href += (s.substring(0,1) == "?") ? "&" : "?" + singleText;
}

I'm using Jquery Load to handels this, works great for me. check out my code from my project. I need to refresh with arguments to put Javascript variable into php

if (isset($_GET['language'])){
    $language = $_GET['language'];
}else{
    echo '<script>';    
    echo '  var userLang = navigator.language || navigator.userLanguage;';
    echo '  if(userLang.search("zh") != -1) {';
    echo '      var language = "chn";';
    echo '  }else{';
    echo '      var language = "eng";';
    echo '  }';
    echo '$("html").load("index.php","language=" + language);';
    echo '</script>';
    die;
}

I used this exact thing before, I have a custom function that I used for the if statement like mentioned by Mark Coleman aswell as submitted a shorter version of his answer but just for the kicks, here is my version

function isOfType(sParam) {
   var sPageURL = window.location.search.substring(1);
   var sURLVariables = sPageURL.split('&');
   var sParameterName = sURLVariables[0];
   return (sParameterName.toLowerCase() == sParam)
}

once you have that function you will use it like this

if(!isOfType('single'))
    window.location.href += '?single';
