How to change css element using jquery

Question

I defined the CSS property as

#myEltId span{
  border:1px solid black;
}

When I click a button, I want to remove its border.

$('#button1').click(function() {
  // How to fetch all those spans and remove their border
});

Answer 1

Just use:

$('#button1').click(
    function(){
        $('#myEltId span').css('border','0 none transparent');
    });

Or if you prefer a long form:

$('#button1').click(
    function(){
        $('#myEltId span').css({
            'border-width' : '0',
            'border-style' : 'none',
            'border-color' : 'transparent'
        });
    });

And I highly recommend reading the API for css()(see links below).

Literature:

• css().

Answer 2

If you use this several times, you can also define a css class without a border:

.no-border {border:none !important;}

and then apply it using jQuery;

$('#button1').click(function(){
        $('#myEltId span').addClass('no-border');
});
