My website has a feature that activates the login button when a user enters their username and password. However, an issue arises when the browser autofills this information, as the login button does not get enabled in such cases. Is there a way to use JavaScript to detect when the browser fills in this information automatically?
One potential solution is to regularly check for it using the setInterval() function, although the rationale behind disabling it before entering details remains unclear.
This approach doesn't appear to be commonly used in practice.
Another approach could be to maintain the button in an active state and validate for a non-empty input upon activation. This method aligns with best practices, as many experts have mentioned.
I haven't personally experimented with this method yet, but one potential approach is to utilize the onchange event for the input fields.
Initially, it's unclear why the default setting wasn't enabled as others have pointed out. However, here is a solution to tackle this issue. Upon page load, simply check if there is any content in the fields. At times, browsers autofill login information when the fields are focused. In such cases, your script should be able to detect the input.
window.onload=function(){
var txt=document.getElementById('username');
if(txt!==''){showSubmit();}
//if you have a preset value you can always do txt!=='username'
}
