I’m struggling to find a good resource on how to execute this. I wanted to redirect the page base on user location. I know this required custom code but at the moment I’m stuck with it and most of the resources that I found are outdated. I’m using ipinfo.io to determine the user country.
Here’s the code that I’m using :
$.get(“https://ipinfo.io”, function(data) {
if(data.country !== “GB”){
console.log(“no gb”)
}else {
var test
test = ‘GB’
console.log(“THIS IS GB”)}
}, “jsonp”);
But then I’m stuck on how to use those value and redirect the page.
If anyone has any experience on this please guide me :pray:t3:
To redirect use location.href
$.get('https://ipinfo.io', function(data) {
if(data.country !== “GB”){
location.href = 'http://ADDRESS-TO-GB'
} else {
location.href = 'http://ADDRESS-TO-ANYWHERE'
}, 'jsonp');
$(function(){
$.get( "https://ipapi.co/json/", function( data ) {
switch(data.country){
case 'US':
window.location = 'http://www.google.us';
break;
case 'KR':
window.location = 'http://www.google.kr';
break;
default:
window.location = 'http://www.google.com';
break;
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.1/jquery.min.js"></script>
you can use a switch case to do redirection base on the callback received data.
try this one
$.getJSON('https://ipinfo.io', function(data) {
if(data.country == 'America'){
location = 'your_redirect_url';
return;
}else if(data.country == 'Beijing'){
location = 'your_redirect_url';
return;
}
})
you can use $.getJSON function then location.href to redirect.
$.getJSON( "https://ipapi.co/json/", function( data ) {
if(data.country !== "GB"){ location.href="your site url"}
if(data.country !== "US"){location.href="your site url"}
});
I am using casperJS to got ta a page and collect an id from the URL, this is what my start function is doing. I would then like to put the id in to a new url and go there.
This works for the user var, this is coming in from the terminal. However sid is undefined and not the value I updated it to.
Any help would be appreciated. I am wondering if I found a limitation with casperJS. please not that this is not the full code (as that is much longer), if you message me I can provide you the whole script.
var user = decodeURIComponent(casper.cli.get(0).replace(/\+/g, ' '))
var sid
casper.start('https://editor.storify.com/', function() {
sid = this.getCurrentUrl()
sid = sid.split('/')[3]
})
casper.thenOpen('https://storify.com/' + sid, function() {
console.log('lets view the posts')
console.log(token)
console.log(sid)
if (dev)
this.capture('storeheading.png')
})
you can solve this problem by warping the thenOpen inside of a then
casper.then(function() {
casper.thenOpen('https://storify.com/' + sid, function() {
console.log('lets view the posts')
console.log(token)
console.log(sid)
if (dev)
this.capture('storeheading.png')
})
})
I have searched extensively for the javascript code to redirect to a different page on the same site and in the same folder and I have tried numerous things. I'm unable to get it to work in localhost or on the web-server. This is what I've tried:
<script type="text/javascript">
function confirm_submit()
{
var con = confirm("Submit form and print invoice?");
var url = 'dashboard.php?del=no';
if (con == true) {
document.location.href = url;
/*I have also tried:
window.location = 'dashboard.php?del=no';
window.location.replace("dashboard.php?del=no");
window.location.href = "dashboard.php?del=no";
*/
}
else {
return false;
}
}
</script>
This is the code on the button :
onclick="return(confirm_submit())"
From everything I've read this should work but it is not working. Can someone please tell me why it is not working and what I need to do to make it work? Thank you in advance.
EDIT: I have answered the question below. It's a workaround, but it is doing the job.
this will work without submitting your form
var url = window.location.href;
splitUrl = url.split("/");
splitUrl[splitUrl.length-1]="your page";
url = splitUrl.join("/");
window.location.href = url;
I have spent too much time on this issue so I have decided to go a different route. I'm using javascript to change the value of a hidden field and then using PHP to redirect to the other page as a result of the posted value of the hidden field. Thanks to all who have given their time to this matter on my behalf. Cheers
<script type="text/javascript">
function confirm_submit()
{
var con = confirm("Submit form and print invoice?");
if (con == true) {
document.getElementById('bool').value = true;
$("#edit_workorder").submit();
}
else {
return false;
}
}
</script>
And the PHP is:
if($bool == true) {
header("Location:dashboard.php?del=no");
exit;
}
It's doesn't really answer the question, but it works and that is more important to me right now.
I've tried everything I can think of to get this "send" button to work, but I'm not very good at javascript :(

Prehaps someone here can tell me where i'm going wrong?
Many thanks

You are binding the submit before the element exists, move the code after the form or put it inside $(document).ready:
jQuery(document).ready(function () {
jQuery("#submit").click(function () {
console.log("button clicked");
// declare these vars
var name = jQuery("#name");
var email = jQuery("#email");
var message = jQuery("#message");
var human = jQuery("#human");
var success = jQuery("#success");
var error = jQuery("#error");
// reset these vars
success.html("");
error.html("");
// ajax call to script.php
jQuery.getJSON("mailer.php", {
name: name.val(),
email: email.val(),
message: message.val(),
human: human.val()
}, function (html) {
// if html from script.php == 1, happy days
if (html == '1') {
jQuery("#contact").hide()
success.html("Thank You, your message has been sent.")
error.show()
}
else {
error.html(html)
}
});
});
});
I'm making a web app that requires that I check to see if remote servers are online or not. When I run it from the command line, my page load goes up to a full 60s (for 8 entries, it will scale linearly with more).
I decided to go the route of pinging on the user's end. This way, I can load the page and just have them wait for the "server is online" data while browsing my content.
If anyone has the answer to the above question, or if they know a solution to keep my page loads fast, I'd definitely appreciate it.
I have found someone that accomplishes this with a very clever usage of the native Image object.
From their source, this is the main function (it has dependences on other parts of the source but you get the idea).
function Pinger_ping(ip, callback) {
if(!this.inUse) {
this.inUse = true;
this.callback = callback
this.ip = ip;
var _that = this;
this.img = new Image();
this.img.onload = function() {_that.good();};
this.img.onerror = function() {_that.good();};
this.start = new Date().getTime();
this.img.src = "http://" + ip;
this.timer = setTimeout(function() { _that.bad();}, 1500);
}
}
This works on all types of servers that I've tested (web servers, ftp servers, and game servers). It also works with ports. If anyone encounters a use case that fails, please post in the comments and I will update my answer.
Update: Previous link has been removed. If anyone finds or implements the above, please comment and I'll add it into the answer.
Update 2: #trante was nice enough to provide a jsFiddle.
http://jsfiddle.net/GSSCD/203/
Update 3: #Jonathon created a GitHub repo with the implementation.
https://github.com/jdfreder/pingjs
Update 4: It looks as if this implementation is no longer reliable. People are also reporting that Chrome no longer supports it all, throwing a net::ERR_NAME_NOT_RESOLVED error. If someone can verify an alternate solution I will put that as the accepted answer.
Ping is ICMP, but if there is any open TCP port on the remote server it could be achieved like this:
function ping(host, port, pong) {
var started = new Date().getTime();
var http = new XMLHttpRequest();
http.open("GET", "http://" + host + ":" + port, /*async*/true);
http.onreadystatechange = function() {
if (http.readyState == 4) {
var ended = new Date().getTime();
var milliseconds = ended - started;
if (pong != null) {
pong(milliseconds);
}
}
};
try {
http.send(null);
} catch(exception) {
// this is expected
}
}
you can try this:
put ping.html on the server with or without any content, on the javascript do same as below:
<script>
function ping(){
$.ajax({
url: 'ping.html',
success: function(result){
alert('reply');
},
error: function(result){
alert('timeout/error');
}
});
}
</script>
You can't directly "ping" in javascript.
There may be a few other ways:
Ajax
Using a java applet with isReachable
Writing a serverside script which pings and using AJAX to communicate to your serversidescript
You might also be able to ping in flash (actionscript)
You can't do regular ping in browser Javascript, but you can find out if remote server is alive by for example loading an image from the remote server. If loading fails -> server down.
You can even calculate the loading time by using onload-event. Here's an example how to use onload event.
Pitching in with a websocket solution...
function ping(ip, isUp, isDown) {
var ws = new WebSocket("ws://" + ip);
ws.onerror = function(e){
isUp();
ws = null;
};
setTimeout(function() {
if(ws != null) {
ws.close();
ws = null;
isDown();
}
},2000);
}
Update: this solution does not work anymore on major browsers, since the onerror callback is executed even if the host is a non-existent IP address.
To keep your requests fast, cache the server side results of the ping and update the ping file or database every couple of minutes(or however accurate you want it to be). You can use cron to run a shell command with your 8 pings and write the output into a file, the webserver will include this file into your view.
The problem with standard pings is they're ICMP, which a lot of places don't let through for security and traffic reasons. That might explain the failure.
Ruby prior to 1.9 had a TCP-based ping.rb, which will run with Ruby 1.9+. All you have to do is copy it from the 1.8.7 installation to somewhere else. I just confirmed that it would run by pinging my home router.
There are many crazy answers here and especially about CORS -
You could do an http HEAD request (like GET but without payload).
See https://ochronus.com/http-head-request-good-uses/
It does NOT need a preflight check, the confusion is because of an old version of the specification, see
Why does a cross-origin HEAD request need a preflight check?
So you could use the answer above which is using the jQuery library (didn't say it) but with
type: 'HEAD'
--->
<script>
function ping(){
$.ajax({
url: 'ping.html',
type: 'HEAD',
success: function(result){
alert('reply');
},
error: function(result){
alert('timeout/error');
}
});
}
</script>
Off course you can also use vanilla js or dojo or whatever ...
If what you are trying to see is whether the server "exists", you can use the following:
function isValidURL(url) {
var encodedURL = encodeURIComponent(url);
var isValid = false;
$.ajax({
url: "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22" + encodedURL + "%22&format=json",
type: "get",
async: false,
dataType: "json",
success: function(data) {
isValid = data.query.results != null;
},
error: function(){
isValid = false;
}
});
return isValid;
}
This will return a true/false indication whether the server exists.
If you want response time, a slight modification will do:
function ping(url) {
var encodedURL = encodeURIComponent(url);
var startDate = new Date();
var endDate = null;
$.ajax({
url: "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22" + encodedURL + "%22&format=json",
type: "get",
async: false,
dataType: "json",
success: function(data) {
if (data.query.results != null) {
endDate = new Date();
} else {
endDate = null;
}
},
error: function(){
endDate = null;
}
});
if (endDate == null) {
throw "Not responsive...";
}
return endDate.getTime() - startDate.getTime();
}
The usage is then trivial:
var isValid = isValidURL("http://example.com");
alert(isValid ? "Valid URL!!!" : "Damn...");
Or:
var responseInMillis = ping("example.com");
alert(responseInMillis);
const ping = (url, timeout = 6000) => {
return new Promise((resolve, reject) => {
const urlRule = new RegExp('(https?|ftp|file)://[-A-Za-z0-9+&##/%?=~_|!:,.;]+[-A-Za-z0-9+&##/%=~_|]');
if (!urlRule.test(url)) reject('invalid url');
try {
fetch(url)
.then(() => resolve(true))
.catch(() => resolve(false));
setTimeout(() => {
resolve(false);
}, timeout);
} catch (e) {
reject(e);
}
});
};
use like this:
ping('https://stackoverflow.com/')
.then(res=>console.log(res))
.catch(e=>console.log(e))
I don't know what version of Ruby you're running, but have you tried implementing ping for ruby instead of javascript? http://raa.ruby-lang.org/project/net-ping/
let webSite = 'https://google.com/'
https.get(webSite, function (res) {
// If you get here, you have a response.
// If you want, you can check the status code here to verify that it's `200` or some other `2xx`.
console.log(webSite + ' ' + res.statusCode)
}).on('error', function(e) {
// Here, an error occurred. Check `e` for the error.
console.log(e.code)
});;
if you run this with node it would console log 200 as long as google is not down.
You can run the DOS ping.exe command from javaScript using the folowing:
function ping(ip)
{
var input = "";
var WshShell = new ActiveXObject("WScript.Shell");
var oExec = WshShell.Exec("c:/windows/system32/ping.exe " + ip);
while (!oExec.StdOut.AtEndOfStream)
{
input += oExec.StdOut.ReadLine() + "<br />";
}
return input;
}
Is this what was asked for, or am i missing something?
just replace
file_get_contents
with
$ip = $_SERVER['xxx.xxx.xxx.xxx'];
exec("ping -n 4 $ip 2>&1", $output, $retval);
if ($retval != 0) {
echo "no!";
}
else{
echo "yes!";
}
It might be a lot easier than all that. If you want your page to load then check on the availability or content of some foreign page to trigger other web page activity, you could do it using only javascript and php like this.
yourpage.php
<?php
if (isset($_GET['urlget'])){
if ($_GET['urlget']!=''){
$foreignpage= file_get_contents('http://www.foreignpage.html');
// you could also use curl for more fancy internet queries or if http wrappers aren't active in your php.ini
// parse $foreignpage for data that indicates your page should proceed
echo $foreignpage; // or a portion of it as you parsed
exit(); // this is very important otherwise you'll get the contents of your own page returned back to you on each call
}
}
?>
<html>
mypage html content
...
<script>
var stopmelater= setInterval("getforeignurl('?urlget=doesntmatter')", 2000);
function getforeignurl(url){
var handle= browserspec();
handle.open('GET', url, false);
handle.send();
var returnedPageContents= handle.responseText;
// parse page contents for what your looking and trigger javascript events accordingly.
// use handle.open('GET', url, true) to allow javascript to continue executing. must provide a callback function to accept the page contents with handle.onreadystatechange()
}
function browserspec(){
if (window.XMLHttpRequest){
return new XMLHttpRequest();
}else{
return new ActiveXObject("Microsoft.XMLHTTP");
}
}
</script>
That should do it.
The triggered javascript should include clearInterval(stopmelater)
Let me know if that works for you

You could try using PHP in your web page...something like this:
<html><body>
<form method="post" name="pingform" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<h1>Host to ping:</h1>
<input type="text" name="tgt_host" value='<?php echo $_POST['tgt_host']; ?>'><br>
<input type="submit" name="submit" value="Submit" >
</form></body>
</html>
<?php
$tgt_host = $_POST['tgt_host'];
$output = shell_exec('ping -c 10 '. $tgt_host.');
echo "<html><body style=\"background-color:#0080c0\">
<script type=\"text/javascript\" language=\"javascript\">alert(\"Ping Results: " . $output . ".\");</script>
</body></html>";
?>
This is not tested so it may have typos etc...but I am confident it would work. Could be improved too...
