阅读更多关于 What's more efficient - storing logs in sql database or files?

问题 I have few scripts loaded by cron quite often. Right now I don't store any logs, so if any script fails to load, I won't know it till I see results - and even when I notice that results are not correct, I can't do anything since I don't know which script failed. I've decided to store logs, but I am still not sure how to do it. So, my question is - what's more efficient - storing logs in sql database or files?

问题 In a loop I append single words to an element using $(".somediv").append(wordArray[i]+" "); In the word array there are some <p> and </p> tags. And if they are added, jQuery seems to close them automatically with a </p> . How can I prevent it from doing that? 回答1: You don't append tags with jquery, you append nodes.
