i have been downloading bootstrap tree list snippet from google.
it have javascript function which look like this
<script>$(function () {
$('.tree li').on('click', function (e) {
var children = $(this).find('> ul > li');
if (children.is(":visible")) children.hide('fast');
else children.show('fast');
e.stopPropagation();
});
});</script>because i need the tree list only show the active list, so i need to trigger it from my list, and check whether this list active or not
i had convert it to become like this, but still didnt work
function showHide(){
var children = $(this).find('> ul > li');
if (children.is(":visible")) children.hide('fast');
else children.show('fast');
e.stopPropagation();
};and also could you explain to me what is the function of e, in function(e),and e.stopPropagation()
this is the complete code, in case someone was asking
