Add params to URL if page gets reloaded - javascript

Heyho, I want to add GET params like?USER_NAME=Max&USER_ID=01 to the URL if the page gets reloaded. I already got a few snippets for changing the URL / adding params. But I need something to detect the page reload and execute a function. Or a way to change the path of the Url directly if the page gets reloaded.
I tried several things like beforeunload and navigation types.
$(window).bind('beforeunload', function() {
// EDIT: vars like uname etc are defined
var newurlgetstring = "?USER_NAME=" + uname + "&USER_EMAIL=" + uemail + "&LAST_NAME=" + lname + "&PRE_NAME=" + fname + "&UTITEL=" + utitel + "&U_ID_T=" + uidt + "&MV=" + mv + "&V=" + uv ;
var newurl = window.location.protocol + "//" + window.location.host +window.location.pathname + newurlgetstring;
window.history.pushState({path:newurl},'',newurl);
});
But I want able to execute a function with beforeunload. I was just able to display a return question.

Send non executable script in body by mailto:

I want to prepare an email to send with mailto:
This email contains a few words and a js script. This script does not need to be executed. It's just for the receiver to copy and paste.
The script :
<script id="myID">var script = document.createElement("script");script.src="script-to-inject.js?id=myID&type=0&name=Name&size=120";document.head.appendChild(script); </script>
And my mailto:
window.location.href = "mailto:"+email+"?subject="+subject+"&body=FewWords"+ script;
When my mail isopen i have something like that :
<script id="myID">var script = document.createElement("script");script.src="script-to-inject.js?id=myID
The end of the script does not appear (after the first &)
How can i fix this ?
Thanks !
You forgot to encode the URL parameters, so the & starts the next parameter.
You can use the encodeURIComponent function:
window.location.href = "mailto:" + encodeURIComponent(email) +
"?subject=" + encodeURIComponent(subject) +
"&body=" + encodeURIComponent("FewWords" + script);
Another, cleaner, way would be to use URLSearchParams:
const url = new URL(`mailto:${encodeURIComponent(email)}`)
url.searchParams.set('subject', subject)
url.searchParams.set('body', 'FewWords' + script)
window.location.href = url
You need to be escaping email, subject, and script properly when setting the href attribute. What if these variables contain the & or the = characters? You can see how this would get misinterpreted.
Try this:
window.location.href = "mailto:"
+ encodeURIComponent(email)
+ "?subject="
+ encodeURIComponent(subject)
+ "&body=FewWords"
+ encodeURIComponent(script);
(I'm not sure that you can pass HTML in the body parameter, by the way, it might get interpreted as plain text.)
You can also use URLSearchParams:
const params = new URLSearchParams();
params.append('subject', subject);
params.append('body', 'FewWords' + script);
window.location.href = 'mailto:' + encodeURIComponent(email) + '?' + params.toString();

generating link using Url.Action with jquery href attr

I'm trying to generate a link using following
$(this).parent().attr('href', '#Url.Action("Create", "Home"' + '?clientId=' + clientId + '&clientName=' + clientName);
somewhere I read that I need to isolate this Url.Action with controller and action into variable so I tried with this
var a = '#Url.Action("Create", "Home"';
$(this).parent().attr('href', a + '?clientId=' + clientId + '&clientName=' + clientName);
But this still doesn't work.
In browser I'm getting
http://localhost:1328/Home/Index2/#Url.Action%28%22Create%22,%20%22Home%22?clientId=181&clientName=undefined
Another option is to store the url with data-* attributes and access them. In the View you can add the below attribute:
data-url='#Url.Action("Create", "Home")'
Now you can access this in the script with:
var base = $(this).data('url');
$(this).parent().attr('href', base + '?clientId='+ clientId +'&clientName=' + clientName);
Your script should be on Razor page in order to make #Url.Action helper work.
When you place it there this should work:
//this line should generate /Home/Create string
var urlNoParam = '#Url.Action("Create", "Home")';
//and here you just add params as you want
$(this).parent().attr('href', urlNoParam + '?clientId=' + clientId + '&clientName=' + clientName);

Open an URL followed by a hash sign using location.href or similar

There is a page with a "share at whatsapp" button. This creates and executes an URL like:
whatsapp://send?text=Some text followed by a link - http://link_to_this_page#something
The problem is that the browser (I've tested only with Chrome for now) automatically deletes from the hash sign to onwards.
I have tried the basic:
var href = 'whatsapp://send?text=Example text - ';
var uri = location.protocol + '//' + location.host + location.pathname + '#gm.';
location.href = href + uri;
I tried too with location.replace(), location.assign() and window.open() with no luck.
So the question is, how can I do? It's imperative to use the hash because it tells to the target page that it has to do some things in javascript (which could take more time to change).
You should be encoding anything that is in the query string.
location.href = href + encodeURIComponent(uri);
You probably should be doing:
var href = 'whatsapp://send?text=';
var text = 'Example text - ';
var uri = location.protocol + '//' + location.host + location.pathname + '#gm.';
location.href = href + encodeURIComponent(text + uri);

facebook share for custom parameters in a link

I am trying to share my custom link on facebook using this javascript function,
function postToFacebook(title, summary, image_url, U)
{
window.open('http://www.facebook.com/dialog/feed?app_id= ' + fb_app_id + '&display=popup&caption=' + title + '&description='+ summary + '&redirect_uri=' + encodeURIComponent('http://facebook.com') + '&link=' + encodeURI(U) + '&picture=' + image_url,'sharer','toolbar=0,status=0,width=548,height=325');
}
In my "U" parameter I have this link => "http://localhost:4000/rings/solitaire-rings/lst?utf8=%E2%9C%93&min_price=&max_price=&name=solitaire-rings&category=rings&fashion_type=false&search=&gallery_order=&new_arrival=&best_seller=&metal_white=on&commit=APPLY"
and when user clicks on the link which is shared on facebook , user should get redirected to this link. forget about root url i.e. localhost:4000, because on production environment its considering required url.
the problem is that whne i am sharing this url on facebook user is getting redirected to "http://localhost:4000/rings/solitaire-rings/lst?utf8", and its not taking care of further parameters which are "%E2%9C%93&min_price=&max_price=&name=solitaire-rings&category=rings&fashion_type=false&search=&gallery_order=&new_arrival=&best_seller=&metal_white=on&commit=APPLY"
basicaaly I supposed to get this URL "http://admin.velvetcase.com/rings/lst?utf8=%E2%9C%93&min_price=&max_price=&name=rings&fashion_type=false&search=&gallery_order=&new_arrival=&best_seller=&search_material_id[]=Diamond&commit=APPLY" , but when I am sharing mu URL on facebook I am getting this one "http://admin.velvetcase.com/rings/lst?utf8=%E2%9C%93&amp%3Bmin_price&amp%3Bmax_price&amp%3Bname=rings&amp%3Bfashion_type=false&amp%3Bsearch&amp%3Bgallery_order&amp%3Bnew_arrival&amp%3Bbest_seller&amp%3Bsearch_material_id[0]=Diamond&amp%3Bcommit=APPLY" , which is not giving e required output.
Here is what I did successfully
var sharingUrl = "https://www.facebook.com/dialog/feed?app_id="+ facebookAppID +
"&link=" + sharingUrl +
"&name=" + encodeURIComponent(title) +
"&caption=" + encodeURIComponent(caption) +
"&description=" + encodeURIComponent(content) +
"&picture=" + encodeURIComponent(thumb) +
"&redirect_uri=https://www.facebook.com";
window.open(sharingUrl);
For all parameters we need to use encodeURIComponent, but I try to not use encodeURIComponent for sharingUrl, it still works!

Replicating base_url in external JS file in CodeIgniter

I have a button in my external js file that, when clicked, I want to be sent to a controller that I have. When I have the on click function in JQuery with the url set to my localhost, it works fine, but how do I set it so that it would work similar to the way the base_url works in CodeIgniter, so that it would work in any environment? I've tried using window.location.origin, or window.location.host instead of the localhost, but neither work. Any ideas?
My external JS button:
var html = '<div class="alert alert-success" role="alert"><p class="instruction_text text-center">' + completedText + '</p></div><input id="next_task" class="btn btn-lg btn-default text-center" style="margin-top: 150px; font-weight: bold;" type="button" value="' + text[lang]['continue'] + '"data-url="http://localhost:8888/oda/sample/instructions/' + task_id + '/' + lang + '/' + type + '">';
$('#final_message').append(html);
$(document).on('click', '#next_task', function(e) {
e.preventDefault();
location.href = $(this).data('url');
});
Thanks!
You can leave that work to the browser. If the page is within the same domain you don't need to put it verbosely on your code, you can put something like that:
'"data-url="/oda/sample/instructions/' + task_id + '/' + lang + '/' + type + '"'
note that the / on the beginning says that it will always get to the same place, disregard the current url.
But, if you need for some reason to write the full url window.location.origin will not include the port part of your url, you would have to include window.location.port too to make it work with your environment. and it's not a necessary thing to do in production.
window.location.host should work if you put http:// and / on your string:
'"data-url="http://' + window.location.host + '/oda/sample/instructions/' + task_id + '/' + lang + '/' + type + '"'
You can define base_url value to the JS variable in view and include all external JS below that
Here, I am giving section of example head.php which is located at /your_root/application/views
<script>
var base_url = "<?php echo base_url(); ?>";
</script>
