AJAX请求不发送validate（）数据

Question

I want to receive the validate function output in my above PHP code. Except my AJAX, all things are working. Can anyone help me correct the problem?

$(document).ready(function(){
    $("#d").click(function(){
        validate();
    })

    function validate() { 
        var x;
        var text;
        var y, senddata;

        x = document.getElementById('t').value;
        y = x.length;

        if (isNaN(x) || y < 10 || y > 10) {
            document.getElementById('t').style.backgroundColor = "red";
        }
        // start AJAX in else case to receive validate data
        else {
            $.ajax({
                url: 'json.php',
                type: "POST",
                dataType:'json',
                data: ({ phone: x }),
                success: function(response){
                    alert ("success !");
                },
                error: function(response){
                    alert("fail!");
                }
            }); 
        }
    }
});

Need to make changes in config to set flag for CORS calls ...

<httpProtocol>
    <customHeaders>
        <!-- Enable Cross Domain AJAX calls -->
        <remove name="Access-Control-Allow-Origin" />
        <add name="Access-Control-Allow-Origin" value="*" />
    </customHeaders>
</httpProtocol>

Also for the AJAX to work please change the condition to go in "else" part
