通过jquery的$.getJSON做一个跨域ajax请求试验
jquery提供了$.getJSON的方法,让我们可以实现跨域ajax请求,但jqueryAPI上的内容实在太少,如何用$.getJSON,请求网站应该返回怎样的数据库才能让$.getJSON获取到,下面就用一个实际例子来说明下。
后端是用php的,以下代码主要实现的一个功能就是提供一个预约登记的接口,需要传入的数据分别有:用户姓名、联系电话和地址
/*预约登记 执行 接口*/
接着就是前端的处理了
/*预约登记 执行 接口*/
代码如下:
/*预约登记 执行 接口*/
case "yuyue_interface":
$name = trim($_GET['name']);
$phone = trim($_GET['phone']);
$addr = trim($_GET['addr']);
$dt = date("Y-m-d H:i:s");
$cb = $_GET['callback'];
if($name == "" || $name == NULL){
echo $cb."({code:".json_encode(1)."})";
}elseif($phone == "" || $phone == NULL){
echo $cb."({code:".json_encode(2)."})";
}elseif($addr == "" || $addr == NULL){
echo $cb."({code:".json_encode(3)."})";
}else{
$db->execute("insert into tb_yuyue (realname,telphone,danwei,dt,ischeck) values ('$name','$phone','$addr','$dt',0)");
echo $cb."({code:".json_encode(0)."})";
}
exit;
break;
接着就是前端的处理了
代码如下:
需要注意的是,在后端php代码里,必须把传递进来的“ &callback=? ”也输出来,如: $(document).ready(function(){
//以下3个为预约登记需要的参数
var name = "name"; //varchar类型,长度最多为8位(4个汉字)
var phone = "phone"; //varchar类型,长度为11位
var addr = "addr"; //varchar类型,长度最多为500位(250个汉字)
$.getJSON("Http://请求网站地址/data.php?ac=yuyue_interface&name="+name+"&phone="+phone+"&addr="+addr+"&callback=?", function(data){
if(data.code==1){
//自定义代码
alert("姓名不能为空");
}else if(data.code==2){
//自定义代码
alert("手机不能为空");
}else if(data.code==3){
//自定义代码
alert("所在单位不能为空");
}else{
//自定义代码
alert("预约成功");
}
});
});
代码如下:
以上就是一个简单的$.getJSON试验,通过这个试验,我们可以学到如何用$.getJSON,也能学到如何做一个接口让别人跨域请求。 $cb = $_GET['callback'];
echo $cb."({code:".json_encode(4)."})";
