How does a browser automatically fill in email and password fields?

When using a text input and a password input in my single page app, Chrome often prompts to remember the information for autofill. However, I am encountering an issue where it doesn't actually autofill the information.

Does anyone know how to troubleshoot this and get it to work properly?

My application is a single page app and all requests are made via AJAX.

Here are my simple input fields:

<input type="text" placeholder="email" autocomplete="on" />
<input type="password" placeholder="password" autocomplete="on" />

I have tried adding autocomplete="on" but it seems like it may not be working due to my lack of form usage. Since I only use Ajax requests, what would be the best way to ensure autofill works correctly?

Answer №1

When using Chrome, it automatically fills in forms for you. To ensure this feature works properly, wrap your form fields in a <form> element without adding a submit input. This way, the form will not disrupt your autofill settings.

As mentioned in that response:

You can find all the regular expressions that Chrome uses to recognize common fields by referring to autofill_regex_constants.cc.utf8. Ensure that the names of your HTML fields match these expressions. Here are some examples:

  • First name: 
    "first.*name|initials|fname|first$"
  • Last name: 
    "last.*name|lname|surname|last$|secondname|family.*name"
  • Email: "e.?mail"
  • Address (line 1): 
    "address.*line|address1|addr1|street"
  • Zip code: 
    "zip|postal|post.*code|pcode|^1z$"
