Adding password visibility to html page in esp32 wifi manager

Postby PRO_GRAMMAR » Thu Apr 13, 2023 1:30 pm

I'm running the wifi manager wifiConnect_Lite https://github.com/smurf0969/WiFiConnect on my esp32 so I don't have to hardcode my wifi credentials. The problem I have is that the html webpage it launches to input your wifi credentials doesn't have the "eye" option next to the password box to toggle visibility to verify input. Does anybody know how to do this. I'm a young coder but willing to try. I'm ok with password being always visible if toggle is problematic to implement. See html code below.

Code: Select all

Quick hack that probably does what you want: change

Code: Select all

<input id=\"p\" name=\"p\" length=64 type=\"password\" placeholder=\"Password123\">
to

Code: Select all

<input id=\"p\" name=\"p\" length=64 type=\"text\" placeholder=\"Password123\">

My God that code is hard to read!

I'm surprised that your browser doesn't add this automatically and would be inclined to investigate this, instead.

Anyways, you could add a Javascript function to reveal the password, switching the password field for a text field:

Code: Select all

<!-- in the HTML -->
<input id="p"  type="password" placeholder="Password123">
<input type="checkbox" onclick="revealPass()">Show Password
<!-- obviously you could do some nice CSS here to place it in the input, or whatever -->

/* in your <script> tag.. */
function revealPass() {
  var x = document.getElementById("p");
  if (x.type === "password") {
    x.type = "text";
  } else {
    x.type = "password";
  }
}

Wasn't quite sure where in code to copy this. Thanks.
