问题 I am wondering how I would put information from my website in the URL on the first page of my site, and then on the next page, use $_GET to get the variables from the URL. I was just wanting to put it in a link like <a href="mywebsite.com/page?name=$name"></a> So would it work if I did it like that, and if it would, how would I get it from the URL? 回答1: do <a href="http://mywebsite.com/page?name=<?php echo $name; ?>"></a> And in your page, you could get the name as: $name = $_GET['name']; 回答2

Personally I find version 2 harder to understand, as to me setdefault is very tricky to grasp. If I understand correctly, it looks for the value of "key" in the

问题 how can i get the number from a div tag's id? example: <div id="button1"></div> how can i get the 1 and store it in a variable? 回答1: var id = $("div").attr('id').replace(/button/, ''); 回答2: Your "id" values cannot be purely numeric; they need to start with a letter or "_" like an identifier. ( Note : that's not true in HTML5 documents.) Once you've got a number in your "id" value like that, you would just use the jQuery attr() function to get the id: var theId = parseInt($('div.whatever')
