如何编写一个程序，以确保在两个字段中输入的密码都匹配？

Question

I want the text "password set" to display if passwords in both fields match? What am i doing wrong? also what are the rules regarding having brackets within script? can i have two functions within the same script tag?

<p>First name:  <input type="text" id="fname" /></p>
<p>Surname: <input type="text" id="sname" /></p>
<p>Date of birth:   <input type="text" id="dob" /> (Please enter as dd/mm/yyyy)</p>
<button onclick="user()">Generate Username</button>
<p id="username"></p>
    <p id="match"></p>

<p>Please enter a password for your account.</p>
<p>Enter password:  <input type="text" id="password1" /></p>
<p>Re-enter password:   <input type="text" id="password2"/></p>
<button onclick="password()">Submit Password</button>

<script>
    function user() {
        document.getElementById("username").innerHTML = document.getElementById("fname").value+document.getElementById("sname").value+document.getElementById("dob").value.slice(-4)
    }

    function password() {
        if document.getElementById("password1").value = document.getElementById("password2").value
            document.getElementById("match").innerHTML = " Your password has been set "
    }
</script>

I hope this helps :)

 function password(){ var pass1 = document.getElementById("password1").value; var pass2 = document.getElementById("password2").value; if(pass1 == pass2){ alert("password match"); }else{ alert("password do not match"); } } 

 <p>Enter password: <input type="password" id="password1" /></p> <p>Re-enter password: <input type="password" id="password2"/></p> <button onclick="password()">Submit Password</button>
