javascript - 防止按钮表单提交Javascript

Question

即使执行了返回值，这个表单仍然不断提交，我的代码有什么问题？

function formhash (form, password)
{
    var pass1 = document.getElementById("password").value;
    var pass2 = document.getElementById("cpassword").value;
    var ok = true;
    if (password != cpassword) {
        //alert("Passwords Do not match");
        document.getElementById("password").style.borderColor = "#E34234";
        document.getElementById("cpassword").style.borderColor = "#E34234";
        ok = false;
        return;
    }
    else
    {
        $.post('insert_home.php'
            {PRIMAID:PRIMAID,EDITCAP:EDITCAP,EDITIMG:EDITIMG,EB_TITLE:EB_TITLE}).done(function(data){
            alert ("Book Successfully Updated");
            location.reload();
        });


        var p = document.createElement("input");    
        form.appendChild(p);
        p.name="p";
        p.type="hidden";
        p.value=hex_sha512(password.value);
        password.value="";
        form.submit();
    }
}

您正在调用 form.submit();，将其删除，它将不会提交。
