Tree using ul li and javascript without plugin

I try to make a simple tree using javascript without plugin in here
Here is my html

<ul class="tree">
    <li>First Child
        <ul>
            <li>First Child
                <ul>
                    <li>First Child</li>
                    <li>Second Child</li>
                    <li>Third Child</li>
                    <li>Fourth Child</li>
                </ul>
            </li>
            <li>Second Child</li>
            <li>Third Child</li>
            <li>Fourth Child</li>
        </ul>
    </li>
    <li>Second Child</li>
    <li>Third Child</li>
    <li>Fourth Child</li>
</ul>

and my js

$( "li" ).on( "click", function() {
    if ($(this).children('ul').css('display') == 'none') {
        $(this).children('ul').css("display", "");
    } else {
        //alert( $( this ).text() );
        $(this).children('ul').css("display", "none");
    }
});

but it only working with first level. How to do that thanks.

Event bubbling is happening out there. use e.stopPropagation() to block that. And by the way you don't need to change/check the display property to make any element visible/hidden, just use .toggle().

Try,

$("li").on("click", function (e) {
    e.stopPropagation();
    $(this).children('ul').toggle();       
});
