JSONP Examples with the Dark Sky API - Script Codes JS Codes

"use strict";
function apiCall(apiURL) { /* -------------------------------------------------------- This codepen shows 3 different ways to use JSONP to work around cross-origin errors. The examples below call the Dark Sky Weather API. ** What is JSONP? ** Browser security usually prohibits you from accessing data on another page unless it has the same origin (domain name / web address). A common error we get when attempting to access data on a different origin is: "XMLHttpRequest cannot load http://external-domain/service. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://my-domain’ is therefore not allowed access." So, JSONP is one way to work around this restriction. To read more about it: https://www.sitepoint.com/jsonp-examples/ http://learn.jquery.com/ajax/working-with-jsonp/ https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS To use it in your application, check out the code below! TL;DR - $.getJSON: add ?callback=? (or &callback=?) to your URL - $.ajax: use dataType: 'jsonp' - no jQuery: append a script to the page with with its src=<<apiURL?callback=callbackFunction>> */ // Comment/Uncomment the functions below. They all give the same results. // See each section below for the code used. getJSON_JSONP(); // $.getJSON example //ajax_JSONP(); // $.ajax example //pure_JS_JSONP(); // pure JavaScript (no jQuery) /* ------------------------------------------------ $.getJSON example With $.getJSON, we request JSONP by simply adding `callback=?` to the end of the URL for our API request. The displayJSON() function is called when complete. Remember that a query string at the end of the url starts with a ? with additional parameters separated by ampersand & https://url?param1&param2 http://api.jquery.com/jquery.getjson/ ------------------------------------------------ */ function getJSON_JSONP() { $.getJSON(apiURL + "&callback=?").done(displayJSON); // show which method we used $("#method-used").text("$.getJSON"); } /* ------------------------------------------------ $.ajax example This function uses $.ajax - a JSONP request is made by adding dataType: 'jsonp' Once the request is complete, the displayJSON function is called to show the results. http://api.jquery.com/jquery.ajax/ ------------------------------------------------ */ function ajax_JSONP() { $.ajax({ url: apiURL, dataType: "jsonp" }).done(displayJSON); // show which method we used $("#method-used").text("$.ajax"); } /* ------------------------------------------------ Pure JavaScript JSONP Example (no jQuery) This function does not use jQuery and it works by appending a script element to the page with the API URL and a callback function as the src. The API is called - when a response comes back, the callback function is called. ------------------------------------------------ */ function pure_JS_JSONP() { // create a script element to append to our page var scriptEl = document.createElement("script"); // use the API URL as the src of our script element and append ?callback=<<function name>> // to the end to specify what function to call when the request is complete scriptEl.src = apiURL + "&callback=displayJSON"; // append the script to the last line of the <body> element document.body.appendChild(scriptEl); // show which method we used document.getElementById("method-used").textContent = "JavaScript (No jQuery)"; }
}
// This is the function we call in all the JSONP examples above to show the results of the API call
function displayJSON(data) { document.getElementById("json-data").innerHTML = JSON.stringify(data.currently, null, 2);
}
// Basic setup. You can ignore this line of code.
// It gets the location and builds the API URL required for the JSONP Examples above.
