How to change default “please fill out this field” in two field

I would like two different messages in two field, for example, the username and password field that contain messages like \"username cannot be blank\" and \"password cannot be b

Answer 1

you make a loop on all your input elements that's why you obtain the same result in each element. Give an id to your input for example username and password, then try :

$(document).ready(function() {
var msg="";
var elements = document.getElementsByTagName("INPUT");
for (var i = 0; i < elements.length; i++) {
    elements[i].oninvalid = function(e) {
        e.target.setCustomValidity("");

        switch(e.target.id){
            case "password" :
            msg="Bad password";
            case "username" :
            msg="Username cannot be blank";
        }

        if (!e.target.validity.valid) {
            e.target.setCustomValidity(msg);
        }
    };
    elements[i].oninput = function(e) {
        e.target.setCustomValidity("");
    };
} })

You can use this code.

   <input type="text"  required="" name="username" placeholder="Username" oninvalid="this.setCustomValidity('Username cannot be blank')">
   <input type="password"  required="" name="password" placeholder="Password" oninvalid="this.setCustomValidity('Password cannot be blank')">

sorry, some mistakes in my code. Try that, that works for me :

$(document).ready(function() {
var msg="";
var elements = document.getElementsByTagName("INPUT");

for (var i = 0; i < elements.length; i++) {
   elements[i].oninvalid =function(e) {
        if (!e.target.validity.valid) {
        switch(e.target.id){
            case 'password' : 
            e.target.setCustomValidity("Bad password");break;
            case 'username' : 
            e.target.setCustomValidity("Username cannot be blank");break;
        default : e.target.setCustomValidity("");break;

        }
       }
    };
   elements[i].oninput = function(e) {
        e.target.setCustomValidity(msg);
    };
} 
})

You may add an id attribute to both your username and password input elements:

<input placeholder="Username" required id="username" />
<input type="password" placeholder="Password" required id="password" />

Then you may use a switch statement to add the custom validation message according to the target of the event:

$(document).ready(function () {
    var elements = document.getElementsByTagName("INPUT");
    for (var i = 0; i < elements.length; i++) {
        elements[i].oninvalid = function (e) {
            e.target.setCustomValidity("");
            if (!e.target.validity.valid) {
                switch (e.srcElement.id) {
                    case "username":
                        e.target.setCustomValidity("Username cannot be blank");
                        break;
                    case "password":
                        e.target.setCustomValidity("Password cannot be blank");
                        break;
                }
            }
        };
        elements[i].oninput = function (e) {
            e.target.setCustomValidity("");
        };
    }
})

Here's a demo.
