A Step-by-Step Guide: Implementing SweetAlert in Your Projects
Let's walk through a practical example of implementing SweetAlert in a web application.
Step 1: Include the SweetAlert Library:
The first step is to include the SweetAlert library in your HTML file. You can download the library from the official SweetAlert website or include it directly from a CDN:
<script src="https://cdn.jsdelivr.net/npm/sweetalert2@11"></script>
Step 2: Display a Basic SweetAlert:
// Display a basic success alert
Swal.fire({
icon: 'success',
title: 'Success!',
text: 'Your data has been saved successfully.',
});
// Display an error alert
Swal.fire({
icon: 'error',
title: 'Oops...',
text: 'Something went wrong!',
});
Step 3: Customize SweetAlert Appearance:
// Customize alert appearance
Swal.fire({
title: 'Are you sure?',
text: 'You won\'t be able to revert this!',
icon: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!',
cancelButtonText: 'Cancel'
}).then((result) => {
if (result.isConfirmed) {
Swal.fire(
'Deleted!',
'Your file has been deleted.',
'success'
)
}
})
Step 4: Implement Input Fields:
// Prompt for user input
Swal.fire({
title: 'Enter your name',
input: 'text',
inputPlaceholder: 'Enter your name',
inputAttributes: {
'aria-label': 'Type your name'
},
showCancelButton: true,
confirmButtonText: 'Submit',
cancelButtonText: 'Cancel'
}).then((result) => {
if (result.isConfirmed) {
Swal.fire(
'Hello, ' + result.value + '!',
'You entered: ' + result.value,
'info'
)
}
})
Step 5: Utilize Progress Bars:
// Display a progress bar
let timerInterval
Swal.fire({
title: 'Auto close in 5 seconds',
html: 'I will close in <strong></strong> seconds.',
timer: 5000,
timerProgressBar: true,
didOpen: () => {
Swal.showLoading()
const b = Swal.getHtmlContainer().querySelector('b')
timerInterval = setInterval(() => {
b.textContent = Swal.getTimerLeft()
}, 100)
},
willClose: () => {
clearInterval(timerInterval)
}
}).then((result) => {
/* Read more about handling dismissals below */
if (result.dismiss === Swal.DismissReason.timer) {
console.log('I was closed by the timer')
}
})
