Yii remember tree state?

Question

JavaScript

There is such a task - to remember the state of the tree. I think to write in session. from here we have - you need js to find out the style of the object console.log(document.getElementById('13').classList.contains('open'));
and somehow pass it to the controller, and then save it to the array. very vague idea how to do it
on click

document.getElementById("tree").onclick = new Function("console.log(this)");

gives a
<ul id="tree" class="filetree treeview">
problem in what

<ul>
<li id="13" class="closed expandable">
<li id="45" class="closed expandable">
<li id="6" class="closed expandable">
<div class="hitarea closed-hitarea expandable-hitarea"></div>
<a class="" href="/proizvodstvo/site/page?view=frameset&frame=6">ЛАЦ</a>
<ul style="display: none;">
</li>
<li id="2" class="closed expandable lastExpandable">
<div class="hitarea closed-hitarea collapsable-hitarea lastCollapsable-hitarea"></div>
<a class="" href="/proizvodstvo/site/page?view=frameset&frame=2">страница</a>
<ul style="display: block;">

that is, the trickster does not have an id diva. but li has an id. How can you refer to an ancestor?

Answer 1

Try using jquery cookies

$('#tree').click(function(){
    if($(this).hasClass('treeview')){
        $.cookie('treeview', 'true');
    } else {
        $.cookie('treeview', 'false');
    }
})

When reloading the page, see the state of $_COOKIE['treeview']
