好的,我有这个PHP代码:
SELECT *
FROM vault
WHERE defendant_client LIKE (SELECT company FROM OpioidCompanies);
我用HTML调用这个脚本:
<!doctype html>
<html>
<body>
<?php
$q = intval($_GET['q']);
$con = mysqli_connect('localhost', 'root', '', 'testDB');
if(!$con){
die('Could not connect: '. mysqli_error($con));
}
mysqli_select_db($con, "testDB");
$query = "SELECT * FROM `aTable`;";
$result = mysqli_query($con,$query);
$row = mysqli_fetch_array($result);
echo $row[$q];
mysqli_close($con);
exit();
?>
</body>
</html>
为什么,控制台记录
if(window.XMLHttpRequest){
xmlhttp = new XMLHttpRequest();
} else {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function () {
if(this.readyState == 4 && this.status == 200){
var Response = this.responseText;
console.log(Response);
}
};
xmlhttp.open("GET", "script.php?q=1", true);
xmlhttp.send();
}
我不知道为什么,但它会返回这些我不想要的HTML标签(只有-3到-1的值[带逗号])
如何删除(未关闭的)HTML标记?
感谢所有答案!
答案 0 :(得分:0)
当您通过ajax调用script.php
时,响应将包含您文件中的所有html标记,请务必将其全部删除。此外,您可能希望使用json_encode函数将php对象作为字符串发送到客户端,这是一个示例:
<强>的script.php 强>
<?php
$q = intval($_GET['q']);
$con = mysqli_connect('localhost', 'root', '', 'testDB');
if(!$con){
die('Could not connect: '. mysqli_error($con));
}
mysqli_select_db($con, "testDB");
$query = "SELECT * FROM `aTable`;";
$result = mysqli_query($con,$query);
$row = mysqli_fetch_array($result);
echo json_encode($row[$q], true);
mysqli_close($con);
exit();
希望这有帮助
