Focus on a field

@IwawaApr 30.2020

I need help with a JS function.
In a PHP form I have a field and, when the focus is lost (moving to another field), it is immediately validated by an onBlur event which in case of error opens a sweet alert.
So far everything Ok.
I would like, however, that when the alert is closed (click OK) the focus returns to the invalid field.
To do this I was suggested to create a small javascript function; as I’m not js expert, can someone help me with an example?
Thanks and best regards.

Please don't. A screenshot is not searchable and copy&paste is not possible when one intends to make a test site. Please copy the text and post it inside code tags: `your code here`

I searched for an onclose event for sweetalert but didn't find any. Instead the same can be done by promises as explained here:

Then you can set the focus by use of the function focus() to the input field again.

Ok, this is the code used in the event onBlur.

$login={fld_login};
 $sql_command =
 "select fld_login from tb_users where fld_login = '{fld_login}'";
 sc_lookup(ds_user, $sql_command);
 if ({ds_user} != false)
 {
 $params = array(
 'title' =&gt; "Error",
 'type' =&gt; "error",
 'width' =&gt; '350px',
 'confirmButtonText' =&gt; 'OK');
 $desc="The entered login: ".$login." "."already used!";
 sc_alert($desc, $params);
 // focus function????
 }  else {
 $params = array(
 'title' =&gt; "Error",
 'type' =&gt; "error",
 'width' =&gt; '350px',
 'confirmButtonText' =&gt; 'OK');
 $desc="This field cannot be empty!";
 sc_alert($desc, $params);
 // focus function ???
 }

When I leave the field, this code validates the field and works properly. If an error occurs the sc_alert function opens a popup for the warning.

When the popup is closed I would return the focus on the same invalid field.

However you are using script case. Unfortunately I don't have any knowledge about this. Maybe someone else can assist you.
