Javascript Question

Scrolling Page with jQuery not working

New to javascript, trying to create a simple program that scrolls to the div when navigation item is clicked. However, its not working, I can't figure out why.

Here is the snippet :



$(document).ready(function() {
alert("asda");

setBindings();
});

function setBindings() {
$("nav a").click(function(e) {
// stops the a tags for working.. i.e. clicking to another page. Functions stops the functionality.
var sectionID = e.currentTarget.id + "Section";
alert('button id ' + sectionID);

$("html body").animate({
scrollTop: $("#" + sectionID).offset().top
}, 1000)
})

})
}

<nav class="clearfix">
<div class="logo-container">
<i><h2><b>DELIVERY MOTION</b></h2></i>

</div>

<ul class="clearfix">
<li><a id="delivery" href="#">Delivery</a></li>
<li><a id="about" href="#">About Us</a></li>
<li><a href="#">Services</a></li>
<li><a href="#">FAQ</a></li>
<li><a href="#">Contact</a></li>

<li><a href="#">Login</a></li>

</ul>



<a href="#" id="pull">Menu</a>
</nav>


<div id="deliverySection">
<h1> Order anything from anywhere in Karachi instantly at your doorstep. </h1><hr>
<div id='fee-estimate-box'>
<form id='fee-estimate-form' action="#">
<legend id='delivery-text'>Delivery Fee Calculator</legend>
<span>FROM </span> <input type="text" name="firstname" value="PICKUP ADDRESS">

At first I thought the problem was with my jquery, however its working fine. The links to javascript is correct too. I've tried rechecking the animate function but I can't pin point the issue. Any ideas?

Answer

$("html body") has to be replaced by $("html,body") for the scroll to trigger. You also had an error in your javascript, one more '})'at the end. Now that's fine. Check your console for such errors, or use snippets, as in your question.

$(document).ready(function() {
    //  alert("asda");
    
        setBindings();
    });
    
    function setBindings() {
        $("nav a").click(function(e) {
  
        var sectionID = e.currentTarget.id + "Section";
       // alert('button id ' + sectionID+ $("#" + sectionID).offset().top);
    
        $("html,body").animate({
          scrollTop: $("#" + sectionID).offset().top
        }, 1000);
        })
    
      }
