This privacy notice provides an overview of our commitment to privacy and describes how we collect, protect, use and share personal information collected through this site. Pearson Education, Inc., 221 River Street, Hoboken, New Jersey 07030, (Pearson) presents this site to provide information about Peachpit products and services that can be purchased through this site. Once it reaches 4, the response is fully loaded and the callback method we set in GoogleAPI.onNewsSearched is triggered. Once the request has been made, the onreadystatechange callback method is triggered through each stage of the readyState. This method creates the request object as a property of GoogleAPI, sets the onreadystatechange callback method, opens the request to the gateway URL we are passing as the argument, and finally sends the request. With the gateway URL constructed, we can make our Ajax request to the Google Search API through a reusable method called GoogleAPI.makeRequest. The search query or q property can be changed to any value using the GoogleAPI.Query variable in the window.onload event where we are initiating all of the object properties. The required arguments v=1.0 and q, which is currently set to “Peachpit”are also included. The GoogleAPI.Index property will later be used to increase the starting point for the search in order to page through results. In this example, we are using rsz=small to retrieve four results, and as the start argument we’re also using the GoogleAPI.Index property to determine from what record to receive the search results. Editions are related to countries and can be defined as us, uk, fr_ca, etc. The value can be any of the following options:Īn optional argument that can be used to pull results from a specific edition. Order search results by relevance or date.Īn optional argument that can be used to get news results from a specific location.Īn optional argument that can be used to filter results to quote type results, instead of typical news type results.Īn optional argument that can be used to filter results to a particular topic. Table 3Google News Search Specific Arguments The optional news search specific arguments that can be used to filter results (Table 3). ![]() When supplied with the callback argument, the context alters the response format normally associated with the callback. This allows us to gather random news results, create controls to navigate through pages of news results, and so on.Īllows you to alter the response format and trigger a function call. However, if you want to retrieve additional news results, you can change the start to 4, which will retrieve news results 4-8. The referrer header is what we are passing in gateway.php.Ī powerful argument that allows you to retrieve pages of resultsfor example, the default is 0 therefore, if you request a small result set, you’ll receive news results 0-4. If this argument is supplied, it must match the passed referrer header in order to be validated. ![]() small retrieves four results, and large retrieves eight results. ![]()
