A站(),有个form表单,ajax提交到 B站(),还附带个验证码
A站上的表单代码如下
<script type="text/javascript" src=http://www.dede58.com/"http:/apps.bdimg.com/libs/jquery/1.6.4/jquery.min.js"></script>
<script>
function send(){
$.ajax({
cache:true,
type:"POST",
url:"",
data:$('#diyform').serialize(),
xhrFields:{withCredentials: true}, //ajax跨域提交需要
crossDomain:true, //ajax跨域提交需要
success: function(data){
if(data=="success"){
alert('发送成功!');
}else{
alert('发送失败!');
}
}
});
}
</script>
<form action="" enctype="multipart/form-data" method="post" id="diyform">
<input type="hidden" name="action" value="post" />
<input type="hidden" name="diyid" value="2" />
<input type="hidden" name="do" value="2" />
<input type="hidden" name="dede_fields" value="name,text" />
<input type="hidden" name="dede_fieldshash" value="c2be5bb5ec45d9d01ca9f60dc469b3fb" />
<p>
姓名:
<input type='text' name='name' id='name' />
</p>
<p>
验证码:
<input type="text" name="validate"><img src=http://www.dede58.com/"http:/www.b.com/include/vdimgck.php" align="absmiddle" onclick="this.src='?tag='+Math.random();" style="cursor:pointer;">
</p>
<div onclick="send()">提交</div>
</form>
1、提交到
2、验证码
3、ajax 跨域必需js代码
xhrFields:{withCredentials: true}, crossDomain:true,
B站上的 /plus/diy.php 文件上面加入 header("Access-Control-Allow-Credentials:true"); header("Access-Control-Allow-Origin:");
