I'm new to web development in general but I'm trying to create my own Contact page on my website and I'm having trouble. I'm using React, Gatsby, and Emailjs. I have my form set up so that the inputs are passed into the state onChange. Then I have a "send message" button that should send an email using EmailJS using the tokens and the state vars. This does all work and the email sends successfully, but it's sending dozens of emails. I believe what's happening is it's calling sendEmail every time the state is set and the DOM re-renders, or basically once for each character that's input into the fields, but I don't know why.
Bonus points if you can help me figure out why pressing the send message button also sends me to a 404 /# route on my site.
import React from 'react'
import emailjs from 'emailjs-com
class Main extends React.Component {
constructor(){
super()
this.state = {
fromName:'',
message:'',
fromEmail:''
}
}
render() {
return (
<div ...
>
...
<article>
...
<form method="post" action="#">
<div className="field half first">
<label htmlFor="name">Name</label>
<input type="text" name="name" id="name" value={this.state.fromName} onChange={e => this.setState({fromName: e.target.value})}/>
</div>
<div className="field half">
<label htmlFor="email">Email</label>
<input type="text" name="email" id="email" value={this.state.fromEmail} onChange={e => this.setState({fromEmail: e.target.value})}/>
</div>
<div className="field">
<label htmlFor="message">Message</label>
<textarea name="message" id="message" rows="4" value={this.state.message} onChange={e => this.setState({message: e.target.value})}
placeholder = "..."></textarea>
</div>
<ul className="actions">
<li>
<input type="submit" value="Send Message" className="special" onClick={this.sendEmail()}/>
</li>
</ul>
</form>
</article>
</div>
)
}
sendEmail() {
const serviceId='...'
const templateId='...'
const userId='...'
emailjs.send(serviceId, templateId, this.state, userId)
}
}
export default Main
The issue is that you never followed the emailjs documentation well and you never prevented the default form action. According to the emailjs documentation you should have set the onClick function with the send email function (without invoking it) on the form's opening tag NOT on your submit button. (but the button is still necessary so that it can send the sign that the form needs to be submitted). You also invoked the sendEmail function which is inappropriate and leads to problems. You must also add event as a parameter in your sendEmail function when creating this function. Then inside the sendEmail function call the event.preventDefault() function .
import React from 'react'
import emailjs from 'emailjs-com
class Main extends React.Component {
constructor(){
super()
this.state = {
fromName:'',
message:'',
fromEmail:''
}
}
render() {
return (
<div>
<article>
<form method="post" onClick={this.sendEmail} action="#">
<div className="field half first">
<label htmlFor="name">Name</label>
<input type="text" name="name" id="name" value={this.state.fromName} onChange={e => this.setState({fromName: e.target.value})}/>
</div>
<div className="field half">
<label htmlFor="email">Email</label>
<input type="text" name="email" id="email" value={this.state.fromEmail} onChange={e => this.setState({fromEmail: e.target.value})}/>
</div>
<div className="field">

sendEmail(event) {
event.preventDefault();

emailjs.send(serviceId, templateId, this.state, userId)
.then((result) => {
console.log(result.text);
