It has how to set focus to the element?

HasFocus know there's more I would have to declare another variable just that this screen will still be more un 15 objects and not like to declare many variables

There is a possibility I set this?

A snippet of code

HTML

<div>
 <input type="text" id="email_log" maxlength="50"  data-bind="value: email_log" name="email_log">                                
 <input type="password" id="password_log" maxlength="10" data-bind="value: senha_log" name="password_log">
                                
<button id="btn_login" data-bind="click: login" >
    <span class="label">OK</span>
</button>
     
</div>                         

JAVASCRIPT
function LoginViewModel() {
    
    this.email_log = ko.observable();
    this.password_log = ko.observable();
 
    this.login= function () {
 
        if (isNullOrWhiteSpace(this.email_log()))
        {
            //to set focus on element here
            alert("Enter the e-mail");            
            return false;
        }
         
            jQuery.ajax({
                url: '/Home/',
                cache: false,
                type: 'POST',
                contentType: 'application/json;charset=utf-8',
                data: '{"email": "' + this.email_log() + '","password": "' + this.password_log() + '"}',
                success: function (data) {                   
                    
                }
            }).fail(function (h, t, e) {
                alert(e);
            });
        
    };
 
}
