I have a website with a language selector. It works great, except that whenever I do change language, it always redirects back to the root page as opposed to staying on whichever current page the user is on.
How can I go about fixing this?
Here is my code:
function checkLanguage() {
let lang = localStorage.getItem('lang');
let urlLang = window.location.pathname.split('/')[1];
if(isNullOrWhitespace(urlLang)) {
if (!lang) {
lang = navigator.language.toLocaleLowerCase();
}
if (lang) {
let userLang = languageDictionary[lang];
changeLanguage(userLang);
}
}
else {
localStorage.setItem('lang', urlLang);
}
var windowWidth = $(window).width();
if (windowWidth < 500 && lang === 'th-th') {
$('.integrations-container').css('display', 'none');
};
};
function isNullOrWhitespace( input ) {
return !input || !input.trim();
}
checkLanguage();
// Changing language
function changeLanguage(lang) {
if (languageOptions.indexOf(lang) === -1) {
return;
}
localStorage.setItem('lang', lang);
window.location.href = '/' + lang;
}
languageOptions = ['en', 'zh-cn', 'zh-hk', 'jp-jp', 'ko-kr', 'th-th'];
languageDictionary = {
'en': 'en',
'en-gb': 'en',
'en-us': 'en',
'zh-cn': 'zh-cn',
'zh-hk': 'zh-ch',
'ko-kr': 'ko-kr',
'th-th': 'th-th',
'jp-jp': 'jp-jp',
}
Thank you kindle in advance! Also I am very new, so laymens terms is always appreciated :)
window.location.href = '/' + lang;
I think this line is always redirecting back to top page when language is changed.
It would be helpful if you can provide the example url of the page.
Try change it to below to redirect to current page when language is changed. I think it should work in top page too.
// Changing language
function changeLanguage(lang) {
if (languageOptions.indexOf(lang) === -1) {
return;
}
localStorage.setItem('lang', lang);
var urlData = window.location.pathname.split('/'); // /en/detail/test.html -> ["", "en", "detail", "test.html"]
urlData.splice(0, 2).join('/'); //cut out ["", "en"]
var newPath = urlData.join('/'); // detail/test.html
window.location.href = '/' + lang + '/'+ newPath; // /jp-jp/detail/test.html
}

I have a code (listed below) that checks if your browser language is set to "de". If your browser is "de" it will send you to the adress "de.html". If it's not "de" you will be sent to "en.html". This works fine but here is the problem:
This is for a Webflow website and they have a editor witch is url/?edit. The code still try to check your language when going to that adress. It just prints out url/?editenenenenenenenenen.. and so on. Is there a way to check if the user is on url/?edit and if so, do nothing?
var lang = window.navigator.language;
var userLang = window.navigator.userLanguage;
if (lang == "de" || userLang == "de") {
window.location.href = window.location.href + "de.html";
}
else {
window.location.href = window.location.href + "en.html";
}
Wrap another if statement around your current if like this:
if (!window.location.href.includes('/?edit')) { ... }
This will check if the user is on url/?edit and if so, does nothing.
As a whole:
var lang = window.navigator.language;
var userLang = window.navigator.userLanguage;
if (!window.location.href.includes('/?edit')) {
if (lang == "de" || userLang == "de") {
window.location.href = window.location.href + "de.html";
} else {
window.location.href = window.location.href + "en.html";
}
}
If the URL is www.somedomain.com/editor?edit, then you can get the ?edit part using :
window.location.search // '?edit'
Using that :
if(window.location.search === '?edit') return;
or more loosely :
if(window.location.search.includes('?edit')) return;
I'm using backbone to manage my routing. I need to implement multi-language on my website as following :
in french : www.example.com
in english : www.example.com/en
Moreover I have an additional root on my url on production, so it gives www.example.com/dev or www.example.com/dev/en
The root is provided through my web server (node). It's retrieved through the <%- prefix %> variable in the example below.
It works well on localhost, but as soon as I pass on my server with a url with the additional root, the pages are not found. I'm looking for a generic solution to manage both situations (with or without root).
<!DOCTYPE html>
<html>
<head>
...
</head>
<body>
<script type="text/javascript">
window.onload = function()
{
let prefix = '<%- prefix %>'.substr(1);
var BaseRouter = Backbone.Router.extend({
routes: {
[prefix + 'imgfocus/:imgid'] : 'imgfocus',
[prefix + 'skymap/:obsids'] : 'skymap',
// ...
},
imgfocus : function(imgid)
{
navservice.loadScreen({page : 'imgfocus', imgid : imgid});
},
skymap : function(obsids, stateid, tourid)
{
navservice.loadScreen({page : 'skymap', obsids : parseInt(obsids) === 0 ? undefined : obsids, stateid : stateid, tourid : tourid});
},
/// ...
});
let br = new BaseRouter();
for (let i = 0; i < navservice.languages.length; i++)
{
if (navservice.languages[i] !== '')
{
for (let key in br.routes)
{
br.routes[navservice.formatUrl(key, navservice.languages[i]).substr(1)] = br.routes[key];
}
}
}
// language retrieval
var language = navservice.getUserLanguage();
Backbone.history.start({pushState : true, root: '/' + (language ? language : '')});
}
$(document).on("click", "a:not([data-bypass])", function (evt) {
var href = { prop: $(this).prop("href"), attr: $(this).attr("href") };
var root = location.protocol + "//" + location.host + Backbone.history.options.root;
if (href.prop && href.prop.slice(0, root.length) === root) {
evt.preventDefault();
var route = href.attr;
// language retrieval
var lang = navservice.getUserLanguage(route);
if(lang && route.slice(0,lang.length+1) === "/" + lang) {
route = route.slice(lang.length+1);
}
Backbone.history.navigate(route, {trigger : true});
}
});
}
</script>
Create differents templates, then use history root option:
Backbone.history.start({pushState: true, root: "/en/"})
More info backbone history start.
Actually I managed to fix it by adding log inside backbone.js and checking what was going on.
The real issue was in the usage of 'prefix' variable in the routes definition. I removed it and most of the fix was done.
I developed a web application and deployed into the server and my security team come up with the below security remidiation issue.
Reflected HTML Parameter Pollution (HPP) is an injection weakness vulnerability that occurs when an attacker can inject a delimiter and change the parameters of a URL generated by an application. The consequences of the attack depend upon the functionality of the application, but may include accessing and potentially exploiting uncontrollable variables, conducting other attacks such as Cross-Site Request Forgery, or altering application behavior in an unintended manner. Recommendations include using strict validation inputs to ensure that the encoded parameter delimiter “%26” is handled properly by the server, and using URL encoding whenever user-supplied content is contained within links or other forms of output generated by the application.
Can any one have the idea about how to prevent HTML parameter pollution in asp.net

As per OWASP Testing for HTTP Parameter pollution, ASP.NET is not vulnerable to HPP because ASP.NET will return all occurrences of a query string value concatenated with a comma (e.g. color=red&color=blue gives color=red,blue).
See here for an example explanation.
That said, your code appears to be vulnerable to XSS instead:
var querystrActivityId = "<%=Request.QueryString["activityId"]%>";
If the query string parameter activityId="; alert('xss');" (URL encoded of course), then an alert box will trigger on your application because this code will be generated in your script tag.
var querystrActivityId = ""; alert('xss');"";
I need to fire piece of jQuery code only if it is home page.
URL probability are
http://www.example.com
http://www.example.com/
http://www.example.com/default.aspx
How can i run code if it is any of the above url i can use
var currenturl = window.location
but then i have to change this every time i move my code to server as on local host my url is like
http://localhost:90/virtualDir/default.aspx
in asp.net we can get the it using various
HttpContext.Current.Request.Url.AbsolutePath
or
HttpContext.Current.Request.ApplicationPath
I am not sure what are the equivalent in jQuery
reference of asp.net example
UPDATE:
I have taken a simple approach as i could not find other easy way of doing it
var _href = $(location).attr('href').toLowerCase()
var _option1 = 'http://localhost:51407/virtualDir/Default.aspx';
var _option2 = 'http://www.example.com/Default.aspx';
var _option3 = 'http://www.example.com/';
if (_href == _option1.toLowerCase() || _href == _option2.toLowerCase() || _href == _option3.toLowerCase()) {
$(".bar-height").css("min-height", "689px");
// alert('aa');
}
else
{ //alert('bb'); }
Could you only include the script on the page where it's needed? i.e. only use <script type="text/javascript" src="homepage.js"></script> from default.aspx ?
If not, then, as dfsq said - use window.location.pathname .
var page = window.location.pathname;
if(page == '/' || page == '/default.aspx'){
// -- do stuff
}
You could just get the part after the last slash, to account for folder differences...
var page = window.location.toString();
page = page.substring(page.lastIndexOf('/'));
... but this would be true for both example.com/default.aspx and example.com/folder1/default.aspx.
Remember, this Javascript is client-side, so there's no equivalent to the C# example you linked.
You could use my approch to know exactly the page (also with urlrouting) to use it in javascript:
I use the body id to identify the page.
javascript code:
$(document).ready(function () {
if (document.body.id.indexOf('defaultPage') == 0) {
/*do something*/
}
});
Asp.net code:
in masterpage or page (aspx):
...
<body id="<%=BodyId %>">
...
code behind:
private string _bodyId;
public string BodyId
{
get
{
if (string.IsNullOrWhiteSpace(_bodyId))
{
var path = GetRealPagePath().TrimStart('/','~');
int index = path.LastIndexOf('.');
if (index > -1)
{
path = path.Substring(0, index);
}
_bodyId = path.Replace("/", "_").ToLower();
}
return string.Concat(_bodyId,"Page");
}
}
public string GetRealPagePath()
{
string rtn = Request.Path;
if (Page.RouteData != null && Page.RouteData.RouteHandler!= null)
{
try
{
if (Page.RouteData.RouteHandler.GetType() == typeof(PageRouteHandler))
{
rtn=((PageRouteHandler)Page.RouteData.RouteHandler).VirtualPath;
}
else
{
rtn = Page.Request.AppRelativeCurrentExecutionFilePath;
}
}
catch (Exception ex)
{
Logger.Error(string.Format("GetRealPagePath() Request.Path:{0} Page.Request.AppRelativeCurrentExecutionFilePath:{1}", Request.Path, rtn), ex);
}
}
return rtn;
}
I am stuck with Social login (Facebook, Google and twitter) through Phonegap.
I have googled and found so many solutions, but they don't work on either platform (i.e: android or iOS).
Does any one have implemented social login in his/her app using phonegap?
If any one could provide me the running code, that would be appreciated.
Thanks,
Sabir
I know it's probably late to answer your particular question but I have had the same issue - all of the current (September 2016) scripts, snippets and libraries for social login in PhoneGap/Cordova that I have tried did not work so I made some simple functions from scratch which may still be useful to people ending up here. You can use them to log the user in with LinkedIn, Facebook and Google(+). I have also made some simple functions that retrieve some basic user information from the access token that is returned by logging the user in with the given network. You can examine the functions but they usually save the token or/and the user data to localStorage for later usage. They have been tested in September 2016 and work perfectly. I hope that this would help other people who also land on failing snippets around the web.
You can just insert the code and use the functions whenever you want. It requires jQuery and PhoneGap's InAppBrowser (besides having made apps/clients in the social media in order to fill the app id and app secret).
As a side note, it is not the best move to store the client secret directly in the PhoneGap application as the source can be viewed by malevolent people.
The code can be refactored at many places, so feel free to do that, but it does the trick. You may also have to handle cases where the user cancels the login process.
