chrome.storage.local.get() 获取存储处理并计数，内部计数正常，外部使用始终为0，百思不得其解。

如何在继续执行之前等待异步chrome.storage.local.get()完成-腾讯云开发者社区-腾讯云 (tencent.com)

原来我忽略了异步问题，最简单的方案就是一次取多个值，并在内部完成所有操作！

javascript">chrome.storage.local.get(['is_light', 'is_hide', 'keyword_light', 'keyword_hide'], function (result) {//console.log(result);if (result.is_light) {var s = result.keyword_light;var sl = s.split(';');var a = document.getElementsByTagName('a');for (var i = 0; i < a.length; i++) {for (var j = 0; j < sl.length; j++) {if (a[i].textContent.indexOf(sl[j]) != -1) {a[i].style.color = 'white';a[i].style.backgroundColor = '#DA3434';a[i].innerHTML = a[i].textContent;count_light++;}}}}if (result.is_hide) {var s = result.keyword_hide;var sl = s.split(';');var a = document.getElementsByTagName('a');for (var i=0; i<a.length; i++) {for (var j=0; j<sl.length; j++) {if (a[i].innerHTML.indexOf(sl[j]) != -1) {a[i].style.display = 'none';count_hide++;}}}}var s = count_light + '+' + count_hide;chrome.runtime.sendMessage({ badgeText: s }, function(response) {//console.log('return: ' + response.farewell);});});
