Js call weather forecast method

China Meteorological Observatory

The code is as follows: Copy code
<Iframe src = "http://m.weather.com.cn/m/pn12/weather.htm" width = "245" height = "110"
Marginwidth = "0" marginheight = "0" hspace = "0" vspace = "0" frameborder = "0"
Scrolling = "no"> </iframe>

The above uses the framework method, so it is difficult to change the format style.

Simplest method

The code is as follows: Copy code

<? Php
Header ("content-type: text/html; charset = utf-8 ");
$ Weather = file_get_contents ("http://www.weather.com.cn/data/sk/101280601.html ");
Echo $ weather;
?>

Html code

The code is as follows: Copy code

<Html>
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gbk"/>
<Style type = "text/css">
. All span {font: bold 30px/50px ""; color: red ;}
</Style>
<Title> weather forecast </title>
</Head>
<Body>
<Div class = "all">
Here is: <span class = "place"> City </span>,
The temperature is <span class = "temp"> temperature </span>,
Wind direction: <span class = "wind"> wind direction </span>,
Wind power: <span class = "windPower"> wind power </span>
</Div>
<Script type = "text/javascript" src = "http: // 127.0.0.1/jquery. js"> </script>
<Script type = "text/javascript">
$ (Function (){
$. Ajax ({
// Request address
Url: "http: // 127.0.0.1/weather. php ",
// The function executed after the request is successful
Success: function (data ){
// Parse the returned data with eval () and convert the string to JSON format
Var oD = eval (+ data + ));
// Get element with jquery-1.8.2
Var $ place = $ (". place "),
$ Temp = $ (". temp "),
$ Wind = $ (". wind "),
$ WindPower = $ (". windPower ");
// Place the returned data to the corresponding location
Using place.html (oD ["weatherinfo"] ["city"]);
$Temp.html (oD ["weatherinfo"] ["temp"] + "° ");
$Wind.html (oD ["weatherinfo"] ["WD"]);
Export windpower.html (oD ["weatherinfo"] ["WS"]);
}
});
})
</Script>
</Body>
</Html>

The above is the specified city. We can select a city on our website. For example:

The code is as follows: Copy code
<? Php
/**
* Php weather forecast code
* By www.111cn.net
*/
If (! Isset ($ _ GET ['Q']) {
// Query the location based on the IP address
$ P = file_get_contents ("http://www.jbxue.com/ip? Q = {$ _ SERVER ['http _ X_FORWARDED_FOR ']} ");
    }
Else {
$ P = $ _ GET ['Q'];
    }
$ K = 0;
$ Encoding = mb_detect_encoding () ($ p );
If ($ encoding! = "UTF-8 "){
$ P = mb_convert_encoding ($ p, "UTF-8", "gbk ");
    }
$ P_arr = array (
"01" => "Beijing ",
"02" => "Shanghai ",
"03" => "Tianjin ",
"04" => "Chongqing ",
"05" => "Heilongjiang ",
"06" => "Jilin ",

"30" => "Guangxi ",
"31" => "Hainan ",
"32" => "Hong Kong ",
"33" => "Macao ",
"34" => "Taiwan"
);
 
Function find (& $ item, $ key, $ data ){
Global $ k;
If (preg_match ("/$ item/u", $ data )){
$ K = $ key;
        }
    }
 
Function get_data_arr ($ key ){
If (! File_exists ("./data/city {$ key}. xml ")){
$ C = file_get_contents ("http://m.weather.com.cn/data5/city?#key=.xml ");
File_put_contents ("./data/city {$ key}. xml", $ c );
        }
Else {
$ C = file_get_contents ("./data/city {$ key}. xml ");
        }
$ Arr = explode (",", $ c );
Foreach ($ arr as $ v ){
$ Data = explode ("|", $ v );
$ Ret [$ data [0] = $ data [1];
       }
Return $ ret;
    }
 
Array_walk ($ p_arr, 'Find ', $ p );
Array_walk (get_data_arr ($ k), 'Find ', $ p );
Array_walk (get_data_arr ($ k), 'Find ', $ p );
$ Ccode = get_data_arr ($ k );
Echo file_get_contents ("http://m.weather.com.cn/data/?ccode=?k=#.html ");
?>
