我要做的是使用PHP生成一系列按钮，这些按钮对应于MySQL数据库中的名称。当用户选择按钮时，它将根据所选按钮在叠加弹出窗口中显示不同的文本。我是PHP，jQuery等新手，所以现在我想尝试一些更简单的工作（没有数据库部分）。这是我的代码：
<!DOCTYPE html>
<html>
<head>
<title>Title</title>
<link rel="stylesheet" type="text/css" href="styles/theme.css">
<script src="scripts/jquery-1.9.1.js"></script>
<script src="scripts/jquery.popupoverlay.js"></script>
</head>
<body>
<?php
echo "<form name=\"idpass\" method=\"post\">";
echo "<div>";
echo "<button name=\"button\" id=\"button1\" value=\"One\" class=\"One_open\" onchange=\"this.form.submit();\">User 1</button>";
echo "<button name=\"button\" id=\"button2\" value=\"Two\" class=\"Two_open\" onchange=\"this.form.submit();\">User 2</button>";
echo "</div>";
echo "</form>";
if(!isset($_POST["button"]))
{
echo "click something";
}
else
{
$buttonSelection = $_POST["button"];
echo "<div id=\"" . $buttonSelection ."\">";
echo "Hello, " . $buttonSelection;
echo "</div>";
}
?>
<script>
$(function()
{
$("button").click(function()
{
var me = $(this);
$('#'+me.val()).popup();
});
});
</script>
</body>
</html>
这将生成两个名为User 1和User 2的按钮。问题是如果我慢慢点击它们，文本（“Hello，One”或“Hello，Two”）只显示在页面上的按钮下方，而不是弹出窗口。如果我足够快地点击它们，它就可以了。所以我知道数据已经通过，但显然存在延迟，我不确定在哪里？
编辑：这是弹出窗口的代码（它不是由我开发的）：

答案 0 :(得分：2)
之前从未使用过这个，但是我看到插件正在修改div并创建新的包装等等。如果你正在修改/生成div，那么可能存在竞争条件。此外，我看不到您在popup()上设置任何选项的位置 - 您似乎想要{autoopen : true}
无论如何，这个小提琴没有竞争条件，因为我正在动态更新一个单独的div的内容，这个div仍然存在并用作模态，因此它似乎工作正常。
$('#modal').popup({autoopen : true});
该插件似乎有一个错误，它只能被实例化，所以我将它添加到克隆元素并在隐藏时将其销毁。如果它有重新打开方法，那么使用我看不到的那个bug。
$(function () {
var destroyModal = function(){
$(this).remove();
}
$("button").click(function () {
var me = $(this);
$('.modal').clone().text( me.val() )
.popup({autoopen : true, onclose : destroyModal});
return false;
}); // end click
}); // end ready
