Is there any way to execute same code for different elements on the page?
$('.class1').click(function() {
some_function();
});
$('.class2').click(function() {
some_function();
});
instead to do something like:
$('.class1').$('.class2').click(function() {
some_function();
});

I normally use on
instead of click
. It allow me to add more events listeners to a specific function.
$(document).on("click touchend", ".class1, .class2, .class3", function () {
//do stuff
});

$('.class1, .class2').click(some_function);
Make sure you put a space like $('.class1,space here.class2') or else it won't work.

If you have or want to keep your elements as variables (jQuery objects), you can also loop over them:
var $class1 = $('.class1');
var $class2 = $('.class2');
$([$class1,$class2]).each(function() {
$(this).on('click', function(e) {
some_function();
});
});

$('.class1, .class2').on('click', some_function);
Or:
$('.class1').add('.class2').on('click', some_function);
This also works with existing objects:
const $class1 = $('.class1');
const $class2 = $('.class2');
$class1.add($class2).on('click', some_function);

Add a comma separated list of classes like this :
jQuery(document).ready(function($) {
$('.class, .id').click(function() {
// Your code
}
});

In addition to the excellent examples and answers above, you can also do a "find" for two different elements using their classes. For example:
<div class="parent">
<div class="child1">Hello</div>
<div class="child2">World</div>
</div>
<script>
var x = jQuery('.parent').find('.child1, .child2').text();
console.log(x);
</script>
This should output "HelloWorld".

We can code like following also, I have used blur event here.
$("#proprice, #proqty").blur(function(){
var price=$("#proprice").val();
var qty=$("#proqty").val();
if(price != '' || qty != '')
{
$("#totalprice").val(qty*price);
}
});

I have a link to an object containig many input fields, which requires to be handled by the same event. So I simply use find() to get all the inside objects, that need to have the event
var form = $('<form></form>');
// ... apending several input fields
form.find('input').on('change', onInputChange);
In case your objects are one level down the link children() instead find() method can be used.

Simply use $('.myclass1, .myclass2, .myclass3')
for multiple selectors. Also, you dont need lambda functions to bind an existing function to the click event.

Another alternative, assuming your elements are stored as variables (which is often a good idea if you're accessing them multiple times in a function body):
function disableMinHeight() {
var $html = $("html");
var $body = $("body");
var $slideout = $("#slideout");
$html.add($body).add($slideout).css("min-height", 0);
};
Takes advantage of jQuery chaining and allows you to use references.
