我想在$ value更改时向价格范围添加一个类。添加产品时为客户提供更好的视觉线索。
尝试:
$(document).ready(function() {
$('.cart-price').bind('DOMCharacterDataModified', function() {
$('.cart-price').addClass('change');
var delay = setTimeout(function(){
$('.cart-price').removeClass('change');
}, 1100)
});
});
CSS:
.cart-price.change
{
color:#F00;
}
答案 0 :(得分:2)
最好使用mutation observers因为mutation events已被弃用。但要注意browser compatibility - IE< 11不支持
$(document).ready(function () {
var $cartprice = $('.cart-price');
if ('MutationObserver' in window) {
var observer = new MutationObserver(highlight);
observer.observe($cartprice[0], {
childList: true
});
} else {
//for browsers which does not support MutationObserver
$cartprice.on('DOMSubtreeModified', highlight)
}
function highlight() {
$cartprice.addClass('change');
var delay = setTimeout(function () {
$cartprice.removeClass('change');
}, 1100)
}
});
