使用JSON和PHP创建天气小部件

标签: javascript php html json

我想要实现的是,一旦用户将城市放入输入中,它将为该特定城市加载Google地图,并在所选城市上显示天气数据。

我是" newish"并且我很难找到如何写出PHP以发送到HTML等的示例等等。

我已经注释掉了一个PHP文件,从我认为我想要实现的目标。这是get-map.js

// start with $(document).ready(...

// Declare the variables: >>geolocation<<, >>lt<<, >>lg<<. You will need them later in the code

// handle click on Get Map here:
// when the button >>#get-map<< is clicked:

    // Declare the variable >>city<<, fetch the value from text-field, trim it and pass it to variable >>city<<

    // if >>city<< is not empty:

        // send the ajax request for json to:
        // https://maps.googleapis.com/maps/api/geocode/json?address=" + city + "&key=yourAPIkey"

        // If request is successful call >>getCity<< otherwise call >>getError<<.
        // These are callback functions belonging to done() and fail() jQuery methods

        // if there is any error message inside the div with class >>.feedback<<, clear it.

    // close if
    // otherwise

        // print the error message to div with the class >>.feedback<< ("please enter the city name...")

    // end of else

// end of click handler



// declare the function >>getCity<< with parameter that stores the object created from json

    // get the value of >>formatted_address<< from the object and pass it to <h2> belonging to 
    // the div with class >>.map-container<<

    // get the values of >>lat<< and >>lng<< from the object and pass them to variables
    // that you declared at the beginning of this document (lt and lg)

    // call the function >>initialize<< and assign its parameters with >>lt<< and >>lg<< values
    // This function is a part of Google Maps JavaScript API. It will draw the map based on the settings 
    // inside the object >>mapOptions<< and based on the given latitude and longitude. This 
    // function will also create the marker

    // clear the input text-field

// end of getCity



// declare the function >>getError<< here (jqXHR, textStatus, errorThrown)

    // alert the eventual error

// end of getError




function initialize(latitude, longitude) {

    // basic setting only (this object has many other properties: 
    // https://developers.google.com/maps/documentation/javascript/controls)
    var mapOptions = {
        center: new google.maps.LatLng(latitude, longitude),
        zoom: 8
    };

    // Draws the map using Map()
    var createMap = new google.maps.Map(document.getElementById("map"), mapOptions);

    // Defines your marker position. Position property is the place where marker shows up
    var startPosition = new google.maps.Marker({
        position: mapOptions.center,
        map: createMap,
        icon: "img/go.png"
    });
}

//准备就绪

这是我的get-weather.js

// start with $(document).ready(...

// Declare the variables: >>geolocation<<, >>lt<<, >>lg<<. You will need them later in the code
// Declare the variable >>collectWeather<< and assign it with empty string. You will need this 
// variable to append weather data coming from json returned by php.


// handle click on Get Weather here:
// when the button >>#get-weather<< is clicked:

    // access div with >>.container<< class inside the div with >>.panel<< class AND display animated gif >>ajax-loader.gif<<

    // Declare the variable >>city<<, fetch the value from text-field, trim it and pass it to variable >>city<<

    // if >>city<< is not empty:

        // send the ajax request for json to:
        // https://maps.googleapis.com/maps/api/geocode/json?address=" + city + "&key=yourAPIkey"

        // If request is successful call >>callWeather<< otherwise call >>getError<<.
        // These are callback functions belonging to done() and fail() jQuery methods

        // if there is any error message inside the div with class >>.feedback<<, clear it.

    // close if
    // otherwise

        // print the error message to div with the class >>.feedback<< ("please enter the city name...")

    // end of else

// end of click handler 



// declare the function >>callWeather<< with parameter that stores the object created from json

    // get the value of >>formatted_address<< from the object and pass it to <h2> belonging to 
    // the div with class >>.weather-container<<

    // get the values of >>lat<< and >>lng<< from the object and pass them to variables
    // that you declared at the beginning of this document (lt and lg)
    // concatenate these 2 variables: lt + "," + lg and pass them to 
    // variable >>geolocation<< that is also declared at the beginning of this document

    // use ajax to request php file. Send >>geolocation<< to php file
    // php file will return the json from forecast.io based on >>geolocation<<
    // The ajax request will have 2 callbacks: >>getWeather<< if successful
    // and >>getError<< if it fails

    // clear the input text-field

// end of callWeather



// declare the function >>getWeather<< with parameter that stores php response

    // use variable >>collectWeather<< to append the values of: 
    // >>icon<<, >>temperature<<, >>humidity<< and >>summary<< (part of the json returned by php)
    // everything will need to be parsed in <ul>.

    // access the div with >>.container<< class inside the div with >>.panel<< class AND 
    // pass the value of >>collectWeather<< in it

    // empty >>collectWeather<<

// end of callWeather



// declare the function >>getError<< here (jqXHR, textStatus, errorThrown)

    // alert the eventual error

// end of getError

//准备就绪
