javascript - 带有CSS效果的JQuery Ui .effect不起作用

问题描述

此表的行有 2 个元素。一种是文本，另一种是隐藏的。如果这些元素的值是different.jQuery-Ui框架，则会突出显示背景颜色（红色）。

$(function() {

  $('table tr').each(function(i, val) {
    var nprice = $(this).children('.unit-price').find("input[type='text']").val();
    var oprice = $(this).children('.unit-price').find("input[type='hidden']").val();

    console.log("nprice: " + nprice);
    console.log("oprice: " + oprice);
    if (nprice != oprice) {
      console.log(i);
      console.log("nprice: " + nprice + "!=" + "oprice: " + oprice);
      var blink = setInterval(function() {
        $('.cart tr:eq(' + i + ') ').effect('highlight', {
          color: 'red'
        }, 1000);
      }, 1000);
      setTimeout(function() {
        clearInterval(blink);
      }, 10000);
    }
  });

突出显示背景颜色效果的功能“效果”不起作用。如何修改 JavaScript 代码或 CSS？

解决方案

尝试callback如下调用。

let i = 2; //I set i for demo purpose. Your i comes from loop, so no need to declare .
$('.cart tr:eq(' + i + ') ').effect('highlight', {
  color: 'red'
}, 1000, callback);

function callback() {
  setTimeout(function() {
    $('.cart tr:eq(' + i + ') ').removeAttr("style").hide().fadeIn();
  }, 1000);
};
.cart td {
  min-width: 50px;
  border-width: 1px;
  border-style: solid;
  border-color: transparent #ddd #ddd;
  padding: 20px;
}
