<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<script type="text/javascript" src="jquery-1.8.2.min.js"></script>
<script type="text/javascript">
$(function(){
$("#send").click(function(){
var cont = $("input").serialize();
$.ajax({
url:'ab.php',
type:'post',
dataType:'json',
data:cont,
success:function(data){
var str = data.username + data.age + data.job;
$("#result").html(str);
}
});
});
});
</script>
</head>
<body>
<div id="result">一会看显示结果</div>
<form id="my" action="" method="post">
<p><span>姓名：</span> <input type="text" name="username" /></p>
<p><span>年龄：</span><input type="text" name="age" /></p>
<p><span>工作：</span><input type="text" name="job" /></p>
</form>
<button id="send">提交</button>

php page:

header("Content-type:text/html;charset=utf-8");
$username = $_POST['username'];
$age = $_POST['age'];
$job = $_POST['job'];
$json_arr = array("username"=>$username,"age"=>$age,"job"=>$job);
$json_obj = json_encode($json_arr);
echo $json_obj;
?>
Use post method
<script type="text/javascript">
$(function(){
$("#send").click(function(){
var cont = {username:$("input")[0].value,age:$("input")[1].value,job:$("input")[2].value};
var url = 'ab.php';
$.post(url,cont,function(data){
var res = eval("(" + data + ")");//转为Object对象
var str = res.username + res.age + res.job;
$("#result").html(str);
});

php字符串有没有下标Apr 24, 2022 am 11:49 AMphp字符串有下标。在PHP中，下标不仅可以应用于数组和对象，还可应用于字符串，利用字符串的下标和中括号“[]”可以访问指定索引位置的字符，并对该字符进行读写，语法“字符串名[下标值]”；字符串的下标值（索引值）只能是整数类型，起始值为0。
