将列表项代码存储在数据库中

Question

我有以下结构:

<ul>
<li code=12>C++</li>
<li code=5>Java</li>
<li code=17>PHP</li>
</ul>

当用户点击保存按钮时,表单将提交给PHP函数.
我想将12,5,17(列表项代码)作为数组传递给PHP函数(带有$ _POST数组)以将其存储在数据库中.
做这个的最好方式是什么？

Answer 1

// Event handler for when you click the button
$("button.save").click(function () {
    var codes = [];

    // For each of your li's with a code attribute
    $("li[code]").each(function () {

        // Stuff the code into an array
        codes.push($(this).attr("code"))
    });

    // You can't post an array, so we turn it into a comma separated string
    codes = codes.join();

    // Do a post request to your server resource
    $.post("/path-to-your-php-code/", {"codes" : codes}, function (response) {
        // Handler for successful post request

        alert("The ajax request worked!");
    });

});

您还需要解析php中的代码字符串,该字符串将在

$_POST["codes"];
