将列表项代码存储在数据库中

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，这些代码将在

中提供

$_POST["codes"];

Answer 2

$.post('url.php', {
      li1:$("li:eq(0)").text(),
      li2:$("li:eq(1)").text(),
      li3:$("li:eq(2)").text()}, function(){
   alert('done');
});
