Passing 10 as the second argument to parseInt is to prevent it from trying to guess the radix based on the string.
In some older implementations, calling parseInt("010") would return 8, not 10. The 0 prefix on the string would be interpreted to mean that the string contains an Octal[^] number.
Even in modern implementations, parseInt("0x10") will return 16, because the 0x prefix denotes a Hexadecimal[^] number.
The isNaN method[^] determines whether the argument is Not a Number. This is a special value returned from parseInt / parseFloat when the input cannot be converted to a number.
So, for example, if the user types in "foobar" for the first number, parseInt will return NaN, and you need to ask the user to type the number again.

Hey abdul,
It works fine for me. Again check this program in some other IDE, it will surely execute.
Hope this helps you.

I've got this script which works out a users pension after they enter in their Total Years in the Scheme 'pensionYears' along with their salary. - This bit works fine - a function called doMath() works out lots of other financial stuff.
I've now put 2 calendars in there: 'dateStart' and 'dateEnd'.
I want to use the difference between these 2 dates to work out the user's total years in service instead of having the user enter in the total years. I've got part of this working - I've got a text box called 'diffYrs' which does work out the difference between the 2 dates.
What I can't do is grab the value from 'diffYrs' and use this in my doMath() function and make 'pensionYears' = 'diffYrs'. Not sure if this is to do with the fact that its outside the scope and needs to be declared as some kind of global variable? - I tried putting everything inside the same function but that didn't work (not sure if that's because one is more a jquery script and other javaScript?)
I was trying to use something like:
var pensionYears = $('#diffYrs');
here's a fiddle:

thanks for looking

Either read the value from the diffYrs input instead of the pensionYears input:
var pensionYears = $('#diffYrs').val();
or update both inputs when the end date changes:
$("#diffYrs, #pensionYears").val(custRound(years,2));
Here's an updated fiddle:

I am trying to write code for my calendar next and previous buttons. But after a lot of tries I still can't figure it out. Here is HTML:
<div class="calendar-container">
<div class="calendar-header">
<a href="#" class="arrows" id="prevArrow">
<div class="prev-arrow-container"></div>
</a>
<div class="year-month-selector">
<select id="year" class="select-properties"></select>
<select id="month" class="select-properties"></select>
</div>
<a href="#" class="arrows" id="nextArrow">
<div class="next-arrow-container"></div>
</a>
</div>
<div class="calendar-body" id="calendar-body">
<div class="day-names" id="dayNames"></div>
<div id="days-container"></div>
</div>
</div>
Here is some JS:
setHandlers() {
var prevButton = document.getElementById('prevArrow');
var nextButton = document.getElementById('nextArrow');
nextButton.addEventListener('click', function () {
this.next();
}.bind(this));}
next() {
var currentYear = this.currentDate.getFullYear();
var currentMonth = this.currentDate.getMonth();
if (currentYear === YEAR_END && currentMonth === 11) {
return;
}
this.currentDate.setMonth(currentMonth + 1);
this.setDate();}
setDate() {
var currentYear = this.currentDate.getFullYear();
var currentMonth = this.currentDate.getMonth();
this.yearSelector.selectedIndex = currentYear - YEAR_START;
this.monthSelector.selectedIndex = currentMonth;}
createDays() {
var daysContainer = document.getElementById('days-container');
var newDate = new Date(this.currentDate.getFullYear(), this.currentDate.getMonth() + 1, 0);
var lengthOfMonth = newDate.getDate();
var date = 1;
for (var i = 0; i < 42; i++) {
var day = daysContainer.children[i];
if(i < this.startingCell) {
day.innerText = "prev";
day.style.opacity = '.2'
} else if (i > this.startingCell + lengthOfMonth){
day.innerText = "next";
day.style.opacity = '.2'
} else {
day.innerText = date;
date++;
}
}}
The whole source can be found here. Any kind of help is appreciated. It would be okay that you give hints about how to link one of the buttons to the calendar-body, that is when of the prev/next is clicked the calendar-body content is changed respectively back and forward. Thanks in advance.

What is your question? I'm not sure many people are going to be willing to download all your code and try to figure out what you want it to do.
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.

Good day friends! I am working on a site and in this site there is HTML link. On click event of the link am calling JavaScript function which is running fine. but when I specify the href of the link the JS function is discarded.

There might be an exception, check your console for errors. F12 for development tools and then check Console for any messages.
Also, use event.preventDefault() to stop the browser from navigating away upon click on the link,
function onclickhandler() {
event.preventDefault();
}
This will do what you need.

thanks for the reply. the link button is Compose. what if person click on Inbox link and from Inbox page click on Compose link? For sure the person will be redirected to Compose page but the popup div appears and disappear after complete load of the page. Any help please.

Then, in such cases if you only want to dynamically update the content instead of having to manage events, I recommend using Single-page applications.
If not, then use my suggestion, that was the answer to disable the browser from navigating to that link itself, you can run the logic as needed.

That is simple, how are you telling JavaScript, where to look for WScript definition? It requires JScript by Microsoft and will only run on Windows, where you can execute wscript.exe executable.
For example, look here javascript - ReferenceError: WScript is not defined - Stack Overflow[^], or here, VBScript and CreateObject issue - Stack Overflow[^]. Then again, it would heavily require clients to have dependencies installed.
If the purpose is just to download, why can't you use native JavaScript, or a minimal C++ program?

The error would tell you what the problem is. Is there a reason you did not include the error?

Hi,
I was wondering if someone could please help me with the following code as it doesn't seem to be working and I cant work out why. Basically, I am attempting to create a document referrer so if a user on a website comes from X site (that site only) then they are redirected to A but if they come from Y they are redirected to B, while if they come from an internal source then they can continue.
The code is:
<pre lang="Javascript">
var regExp = /https:\/\/(anon.to)\/(xxxxxx)/g;
var dr = document.referrer;
if (dr == '') {
self.location='WebsiteExample1';
} else if (dr.match(regExp)) {
self.location ='Otherplaceonwebsite';
}
The code works if I just use var regExp = /https:\/\/(anon.to)/g; but that allows anyone from anon.to to access the link rather than just the users with the https://anon.to/xxxxxx link.
Hopefully this makes sense and someone can help.
Thanks,
|

Quote: Create a secure anonymous short link from your url which also hides http referer!
The service you're using deliberately hides the referrer information. Therefore, you can't use the referrer to detect whether the user came from your anon.to link.

I have deleted your other versions of this question, please post once only. Also, you need to explain what your problem is.

Even a device has active GPS it is possible that your JS code will not benefit from this, that because browsers will not let you know the location without permission from the user... The problem is that browsers remember the hoise for every site, so once the user voted 'no' you have no way to force him choose again...
But, there is one way may help you... Connect 'getCurrentPosition' - directly - to a button click, in this case it considered as an action by the user and will be permitted... Of course you have to exactly describe to the user what will happening what clicking the button...

Quote: How to find user device is gps is on or off Android or ios using js?
You are aware of the fact that GPS is a system feature in Android and not a browser feature, right? You can get the location, but to detect or determine you will have rely on the user, as browser won't be able to trigger changes itself.
Offline devices will return the most recent locations, not accurate or live locations. If you mean to say that location APIs are available then read here,
Common sources of location information include Global Positioning System (GPS) and location inferred from network signals such as IP address, RFID, WiFi and Bluetooth MAC addresses, and GSM/CDMA cell IDs, as well as user input. No guarantee is given that the API returns the device's actual location. So, you can simply request the users to enable GPS for better results.
Also, you should try to check for navigator.geolocation to be set to null or not, otherwise results may be generated.
if (navigator.geolocation) {
} else {
}
