function searchAppmenus() {
var input, filter, ul, li, a, i;
input = document.getElementById("txt_search");
filter = input.value.toUpperCase();
ul = document.getElementsByClassName("nav");
li = ul.getElementsByTagName("li");
for (i = 0; i < li.length; i++) {
a = li[i].getElementsByTagName("a")[0];
if (a.innerHTML.toUpperCase().indexOf(filter) > -1) {
li[i].style.display = "";
} else {
li[i].style.display = "none";
}
}
}
This code is not working. what's wrong with this code.
Please anyone there to Solve this..

Consider the following.
$(function() {
function filterMenu(term) {
var filter, input = term.toUpperCase();
$(".nav a").each(function(i, el) {
filter = $(el).text().toUpperCase();
if (filter.indexOf(input) < 0) {
$(el).parent().hide();
}
});
}
$("#txt_search").keyup(function(event) {
// Show all Items
$(".nav li").show();
// If Empty, do nothing
if ($(this).val() !== "") {
// Filter out items that do not match
filterMenu($(this).val());
}
});
});

This answer is offered in jQuery. It iterates all the anchors and looks for the term in the text of the item. If it's not found, it is hidden.

Multiple dropdown menus triggering on the same click event

I have the following code from this link which seems to trigger the slideToggle event for both drop-down menus. I can't seem to find a solution to triggering only the child drop-down menu of the clicked li element.
A jQuery solution would be best if possible!
var hi = $( '.header-item.has-sub' );
var hdd = hi.children( '.header-sub' );
hi.each(function() {
$(this).click(function() {
hdd.toggleClass( 'open' );
hdd.slideToggle( 'fast' );
});
});
ul li > ul {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul class="header-menu">
<li class="header-item">
<a href="#">
<i class="uil uil-cog"></i>
<span>Settings</span>
</a>
</li>
<li class="header-item has-sub">
<a href="#">
<i class="uil uil-bell"></i>
<span>Notifications</span>
</a>
<ul class="header-sub">
<li class="sub-item">
<a href="#">
<i class="uil uil-edit"></i>
<span>Details</span>
</a>
</li>
<li class="sub-item">
<a href="#">
<i class="uil uil-map-marker"></i>
<span>Address</span>
</a>
</li>
<li class="sub-item">
<a href="#">
<i class="uil uil-signout"></i>
<span>Log Out</span>
</a>
</li>
</ul>
</li>
<li class="header-item has-sub">
<a href="#">
<i class="uil uil-user"></i>
<span>Profile</span>
</a>
<ul class="header-sub">
<li class="sub-item">
<a href="#">
<i class="uil uil-edit"></i>
<span>Details</span>
</a>
</li>
<li class="sub-item">
<a href="#">
<i class="uil uil-map-marker"></i>
<span>Address</span>
</a>
</li>
<li class="sub-item">
<a href="#">
<i class="uil uil-signout"></i>
<span>Log Out</span>
</a>
</li>
</ul>
</li>
</ul>

You need to check in your click event
$('.header-item.has-sub').click(function() {
var hdd = $(this).find('ul.header-sub');
$(hdd).toggleClass('open').slideToggle('fast');
});
ul li > ul {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul class="header-menu">
<li class="header-item">
<a href="#">
<i class="uil uil-cog"></i>
<span>Settings</span>
</a>
</li>
<li class="header-item has-sub">
<a href="#">
<i class="uil uil-bell"></i>
<span>Notifications</span>
</a>
<ul class="header-sub">
<li class="sub-item">
<a href="#">
<i class="uil uil-edit"></i>
<span>Details</span>
</a>
</li>
<li class="sub-item">
<a href="#">
<i class="uil uil-map-marker"></i>

</a>
</li>
<li class="sub-item">
<a href="#">

</ul>
</li>

<a href="#">
<i class="uil uil-user"></i>

</a>
<ul class="header-sub">
<li class="sub-item">
<a href="#">
<i class="uil uil-edit"></i>

treeview expanding all elements that have children

I have a sidebar that has children on certain li elements, I have written some code in jQuery that should target each method, yet when I click on the list element, it slidetoggles all that have children.
my code:-
//dropdown toggle on treeview
const hasTree = $('.has-treeview'),
treeView = $('.nav-treeview');
$.each(hasTree,function(){
$(this).click(function(){
$(treeView).slideToggle();
});
});

so basically I just want to expand the treeview for the one that was clicked, not all of them. Where am I going wrong?
jsfiddle https://jsfiddle.net/xpvt214o/661999/

Try this:
//dropdown toggle on treeview
const hasTree = $('.has-treeview');
$.each(hasTree,function(){
$(this).click(function(){
$(this).children('.nav-treeview').slideToggle();
});
});
JSFiddle

//dropdown toggle on treeview
const hasTree = $('.has-treeview'),
treeView = $('.nav-treeview');
$(hasTree).click(function(){
$(this).find('.nav-treeview').slideToggle();
});
Only add listeners to elements with hasTree classes and than find their treeview and toggle it.

How to scroll a portion of my window using protractor-jasmine

I want to test by clicking an element which is only visible when the sidebar section is scrolled. The sidebar is in the left end of the website and the element is in the bottom portion of the sidebar. I used:
browser.executeScript('window.sidebar.scrollTo(0,0);').then(function ()
but it's not working.

Specify the position at what location you have to scroll, try this one.
browser.executeScript('window.scrollTo(0,1000);').then(function () {
browser.sleep(5000);
console.log('Window ScrollTo','Done');
}).then(function() {
//wait for element to be displayed
browser.driver.wait(function(){
return someElement.isDisplayed().then(function (isVisible){
return isVisible === true;
},50000, 'Element not present ' );
},50000)
});

I've been using this line for scrolling.
You can also try it on console before using it on protractor.
e.g. $(".sidebar").scrollLeft(1000)
strPixels = 1000 //value in pixel
strClass = '.sidebar' //class of the element with scrollbar
browser.executeScript('$("' + strClass + '").scrollLeft(' + strPixels + ')');
Note: you can use scrollLeft or scrollTop to scroll horizontally or vertically.

var filter = theSwitch.pageBar;
var scrollIntoView = function () {
arguments[0].scrollIntoView();
};
browser.executeScript(scrollIntoView, filter);
theSwitch.pageBar.click();

How to add nav-active class in in navigation using jquery only one time

Please help me to sort out this problem. I want to add nav-active class in li element only one time means if child element is selected then parent li should not have nav-active class. I am using following code but it is not working according to my requirements.
Thanks in advance.
Here is my code:
$('ul li').find('li').click(function(){
var $this = $(this);
$('li').removeClass('nav-active');
$this.addClass('nav-active');
});

In you current example if you will do a console.log($(this), it will show you 2 elements in the console if you have clicked a child element. One for the child element and one for its parent li element. This is called event bubbling. You need to take care of event bubbling by stop propagating the event.
Try this.
$('li').click(function(event){
event.stopPropagation()
var $this = $(this);
$('li').removeClass('nav-active');
$this.addClass('nav-active');
});
.nav-active a
{
color:red;
}

The main idea is to run the click function only once because when you click child element the parent element also gets clicked automatically right after that so $(this) ends up selecting parent item, everytime the child element gets clicked.
I added css for .nav-active class to show the code working. Try this.
$(document).ready(function(){
$('nav li').one("click",function(){
$('nav li').removeClass('nav-active');
$(this).addClass('nav-active');
})
})
.nav-active>a>span{
font-size:20px;
color:red;
}
