这是我的 test.php 页面。我需要将 x 变量上的数据传递给 uid 变量。
当我运行代码时，它也会给我成功警报。但也给出了一个错误说，
Notice: Undefined variable: uid in C:\wamp64\www\FinalFinalFinalProject\test.php on line 47 Call Stack #TimeMemoryFunctionLocation 10.0012235232{main}( )...\test.php:0 ">
<?php
$user = "anuradha";
?>

请帮帮我。
最佳答案
正如我所看到的，您需要输入中的 data-id 值，您可以仅使用 JQuery 来完成此操作，为什么要执行 ajax?
<script type="text/javascript">
$(document).ready(function(){
$(".btn-info").click(function(){ // Click to only happen on announce links
var x = $(this).data('id');
$("#username").val(x);
});
});
</script>
