SweetAlert2 : Validation required for one of the fields - validation

Question

I am trying to perform validation on one of the fields in the form.
Only if the value for that field exists will I be able to invoke the API, if not an error message will be thrown.
I tried various examples from SweetAlert2's website. I just want the validation for one of the fields.
Swal.fire({
title: 'Are you sure you want to Save the Notes?',
type: 'info',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes'
}).then((result) => {
console.log('result.value',result.value);
if (result.value) {
Swal.fire( {
title: 'Download Notes',
html:"<div class='b'><p>ID</p></div><input id='swal-input2' class='swal2-input' required/><div class='b'><p>Notes</p></div><input id='swal-input1' class='swal2-input' autofocus minlength='500' >",
confirmButtonText: 'Save',
preConfirm: (login) => {
console.log('document.getElementById(swal-input2).value',document.getElementById('swal-input2').value);
request_string = {
"Request":
[
{
"Col1": "value1",
"Col1": "value2",
"Col1": document.getElementById('swal-input2').value,
"Col1": document.getElementById('swal-input1').value,
}
]
};
fetch('API_URL', {
headers: {
'Accept': 'application/json, text/plain, application/xml, */*',
'Content-Type': 'application/json',
'Access-Control-Allow-Headers': 'Content-Type',
},
method: 'POST',
body: JSON.stringify(request_string)
}
).then(response => {
if (response.status !== 200) {
return;
}
response.text().then(data => {
response_data = data;
response_jsonObj = JSON.parse(response_data);
});
}).catch(error => this.setState({ error }));
},
allowOutsideClick: () => !Swal.isLoading()
}).then((result) => {
swal({
title: " Your request is being processed!",
icon: "success",
confirmButtonText: 'OK'
}).then((okay) => {
if (okay) {
history.push('/page1');
history.push('/page2');
}
});
});
}
})

Answer 1

If you just want to make sure that the first input (i.e. swal-input2) is not null, then you simply need to add preConfirm like that:
preConfirm: () => {
if (document.getElementById('swal-input2').value) {
// Handle return value
} else {
Swal.showValidationMessage('First input missing')
}
}
You can find the working solution here

Answer 2

For those who try to get every inputs with a required attribute try this :
inputAttributes: {
input: 'number',
required: 'true'
}

Hi folks this as been fixed here is the code sample for the same :
Swal.fire({
title: 'Are you sure you want to Save the Notes?',
type: 'info',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes'
}).then((result) => {
console.log('result.value',result.value);
if (result.value) {
Swal.fire( {
title: 'Download Notes',
html:"<div class='b'><p>ID</p></div><input id='swal-input2' class='swal2-input' required/><div class='b'><p>Notes</p></div><input id='swal-input1' class='swal2-input' autofocus minlength='500' >",
confirmButtonText: 'Save',
preConfirm: () => {
if((document.getElementById('swal-input2').value == "") || (document.getElementById('swal-input2').value == '') || ((document.getElementById('swal-input2').value == null)) ){
Swal.showValidationMessage(
`ID is a required field`
)
}
}
}).then((result) => {
request-string = {
"Request":
[
{
"COL1": VALUE1,
"COL2": VALUE2,
"COL3": VALUE3,
"COL4": VALUE4,
"COL5" : VALUE5,
"COL6" : VALUE6,
"COL7": VALUE7
}
]
};
;
fetch('API_URL', {
headers: {
'Accept': 'application/json, text/plain, application/xml, */*',
'Content-Type': 'application/json',
'Access-Control-Allow-Headers': 'Content-Type',
},
method: 'POST',
body: JSON.stringify(request-string)
}
).then(response => {
if (response.status !== 200) {
return;
}
response.text().then(data => {
response_data = data;
response_jsonObj = JSON.parse(response_data);
this.setState({ state: response_jsonObj });
});
}).catch(error => this.setState({ error }));
swal({
title: "Request Submitted Successfully!",
icon: "success",
confirmButtonText: 'OK'
}).then((okay) => {
if (okay) {
history.push('/page1');
history.push('/page2');
}
});
});
