I'm trying to select the list item above a button and change its parent's background-color
to red.
<li>red bg on click <input class="addtocart" value="press" name="button"></li>
<li>red bg on click <input class="addtocart" value="press" name="button"></li>
<li>red bg on click <input class="addtocart" value="press" name="button"></li>
<li>red bg on click <input class="addtocart" value="press" name="button"></li>
jQuery so far:
$(document).ready(function() {
$(".addtocart").click( function(){
$('li').parent().css('background-color', 'red');
});
});
From what I can see it looks correct, but it seems to be changing a different element's background-color
.
Thanks
用this
$(this).parent().css('background-color', 'red');
Try:
$(document).ready(function() {
$(".addtocart").click( function()
{
$(this).closest('li').css('background-color', 'red');
}
);
});
Your selector is wrong . Try to use this
for current element
When you use $('li')
it will apply to all li
elements
$(this).parent().c....
尝试更改为此:
$(this).parent().css('background-color', 'red');
