PHP做響應jsonp的操作。

我做跨域用到了vue-resource ，這個百度一下就能下載：

下面是HTML頁面ajax：

加上 v-model=" " 之後；js方法裡會檢查到裡面的 value 值

<script src="js/lib/jquery.js" type="text/javascript" charset="utf-8"></script>
<script src="js/lib/vue.js" type="text/javascript" charset="utf-8"></script> 

<script src="js/lib/vue-resource.js" type="text/javascript" charset="utf-8"></script>

<input class="name-input" type="text" name="" value="" v-model="name"/> 

<input class="password-input" type="password" name="" value="" v-model="password"/>

<span class="login-btn" @click="add()">登入</span>

<script>      
var vm = new Vue({
 el: ".main",
        data: {
            name: "",
            password: ""
        },
        methods: {
            add: function () {
                this.$http.jsonp("域名/login"
, {
name: this.name,
pass: this.password
}
                ).then(function (res) {
if (res.data.type == "1") {
window.location.href = "cg.html";
} else {
alert("賬號密碼錯誤")
}
}, function (res) {
alert("驗證失敗請重新登入")
});
            }
        }
    })
</script>
public function login(){
$callback = $_GET['callback'];  //這個很重要
$name = $_GET['name'];
$pass = $_GET['pass'];
 
if($name=='123456' and $pass=='123456'){
$json = array('type'=>1,'name'=>$name,'pass'=>$pass);  //登入值錯誤
} else {
$json = array('type'=>0,'name'=>$name,'pass'=>$pass);  //登入值正確
}
$date = json_encode($json);

echo $callback."($date)";
}


成功後則跳轉到cg.html頁面；
