This article mainly introduces the use of jsonp by native JS and jQuery to obtain "current weather information". It has a certain reference value. Now I share it with you. Friends in need can refer to it

Required Skill points mastered:

jsonp, cross-domain correlation, etc.

The following two codes can be run directly.

1. Use native JS:

<!DOCTYPE html><html lang="en"><head>
    <meta charset="UTF-8">
    <title>Title</title></head><body>
    <p id="cur_year"></p>
    <p id="iciba_ds"></p></body></html><script type="text/javascript">
    document.getElementById("cur_year").innerHTML =new Date();    function data(data){        //遍历
        var description = "";        for(var i in data.result){            var property=data.result[i];
            description+=i+" = "+property+"<br />";
        }
        document.write(description);
    }</script><script type="text/javascript" src="http://api.k780.com:88/?app=weather.today&weaid=412&&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=json&jsoncallback=data"></script>

2. Use jquery:

<!DOCTYPE html><html lang="en"><head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script type="text/javascript" src="jquery-3.3.1.min.js"></script>
    <script>
        $(document).ready(function(){
            $.ajax({
                type          : &#39;get&#39;,
                async         : false,
                url           : &#39;http://api.k780.com/?app=weather.today&weaid=412&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=json&jsoncallback=data&#39;,
                dataType      : &#39;jsonp&#39;,
                jsonp         : &#39;callback&#39;,
                jsonpCallback : &#39;data&#39;,
                success       : function(data){                    if(data.success!=&#39;1&#39;){
                        alert(data.msgid+&#39; &#39;+data.msg);
                        exit;
                    }                    //遍历
                    var description = "";                    for(var i in data.result){                        var property=data.result[i];
                        description+=i+" = "+property+"<br />";
                    }
                    document.write(description);
                },
                error:function(){
                    alert(&#39;fail&#39;);
                }
            });
        });    </script></head><body></body></html>
