想必大家对ajax调用有所熟悉，下面为大家介绍下iframe式ajax调用,需要的朋友可以参考下
1.新建 a.html代码如下:<!doctype html><html><head><meta charset='utf-8'><title>iframe式ajax调用</title></head><body><form action='b.php' method='post' name='' id='' target='formTarget'><input type='text' name='username' id='' placeholder='' value='' /><input type='submit' name='' value='提交' /><span id='msg'></span></form><iframe src='' name='formTarget' id='formTarget' style='display:none'></iframe></body></html>2.新建 b.php代码如下:<?phpecho "<script>parent.document.getElementById('msg').innerHTML = 'iframe式ajax调用成功!';alert('您输入的是：{$_POST['username']}');window.setTimeout(function(){parent.window.location.reload();},3000);</script>";3.访问: http://localhost/a.html
