I want my website to have the ability to send an email without refreshing the page. So I want to use Javascript. Here is how I want to call the function, but I'm not sure what to put into the javascript function. From the research I've done I found an example that uses the mailto method, but my understanding is that doesn't actually send directly from the site.

So my question is where can I find what to put inside the JavaScript function to send an email directly from the website. Another solution would be to do an ajax call to your server, so that the server sends the email.

Be careful not to allow anyone to send any email through your server. Your server can call the 3rd Party API after proper authentication and authorization. The API Keys are not exposed to client. Send an email using only JavaScript. Note: Keep in mind that your API key is visible to anyone, so any malicious user may use your key to send out emails that can eat up your quota.

It's called PostMailand you can simply post a form, use Javascript or jQuery. Here are some examples:. Based on the context of the OP's question, my answer above does not hold true anymore as pointed out by KennyEvitt in the comments. So, I can neither encourage nor discourage you to use it.

Use at your own risk. I know I am wayyy too late to write an answer for this question but nevertheless I think this will be use for anybody who is thinking of sending emails out via javascript.We are always striving to improve our documentation quality, and your feedback is valuable to us.

How could this documentation serve you better? Ready to implement user account verification in your application? Here's how it works at a high level:. Our first order of business is to create a model object for a user of our application. We will borrow a lot of the code from the User model in the 2FA tutorial that uses Authy as well.

This application uses MongoDB for persistence, but in our code we will primarily interface with Mongoosea higher-level object modeling tool which is backed by MongoDB. You'll notice an authyId property on the model - this is required to support integration with the Authy API. We won't use this property right away but we'll need it later for the Authy integration. One of the properties on the User model is the password. It is not in scope for this tutorial, but take note: you'll probably want it later for logging in a returning user.

When we create a new user, we ask for a name, e-mail address, password and mobile number including country code. In order to validate the user account we use Authy to send a one-time password via SMS to this phone number. Now the user is logged in but not verified. In the next steps we'll learn how to verify the user using Authy. In config.

Most are pulled in from system environment variables, which is a helpful way to access sensitive values like API keys.

JavaScript | Program to generate one-time password (OTP)

This prevents us from accidentally checking them in to source control. Now, we need our Authy production key sign up for Authy here. Once you create an Authy application, the production key is found on the dashboard:. Next, we need to jump over to the User model to configure the Authy client and create an instance method to send a one-time password. When it comes time to actually send the user a verification code, we do that in a User model function.

Before sending the code, an Authy user needs to exist and correlate to our User model in the database. Once the user has an authyIdwe can send a verification code to that user's mobile phone using the Authy API client. After the user receives the verification code, they will pass it to the application using this form.

This controller function handles the form's submission. It's a little longer than the others, but it has a lot to do. It needs to:. Take a look at the User model to see the instance method that handles verifying the code with Authy.

This instance function is a thin wrapper around the Authy client function that sends a candidate password to be verified. We call Authy's built-in verify function, and then immediately call a passed callback function with the result. This is a great start, but what if your code never reaches the end user's handset?

Authy can help us to re-send a missing code. This controller function loads the User model associated with the request and then uses the same instance function we defined earlier to resend the code.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

So, when we have to start the node server, we just need to write the following command. If we change the file, then it will restart the server automatically. Create one directory in the root folder called the public. What is process. In the root folder, we also need to create one more folder called views.

In that create one file called index. We have used bootstrap CSS class here, so the first thing we need to do is include the library inside the public folder.

Also, create one route for the home page by typing the following code. Now, if you have not started the server yet, please initiate the server by the following command. It will start at the port Create one bootstrap form to send the email. We are going to put that form in the index. Our primary form will look like this. Now, set the post action of the form.
