I'm looking for a way to retrieve the HTML content of a webpage using JavaScript, even if it's on a different domain. Similar to what wget does but in JavaScript. I intend to use this for web crawling purposes.
Could anyone guide me on how to fetch and store the content of a webpage into a string using JavaScript, assuming I have the URL?
Give this a shot:
function retrieveData(data) { alert(data.results[0]); }
$.getScript('http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22' +
encodeURIComponent(url) + '%22&format=xml&diagnostics=true&callback=retrieveData');
To retrieve content via HTTP using JavaScript, the recommended approach is to utilize the XMLHttpRequest object. However, this method is restricted by the same origin policy, which means accessing data from different domains requires bypassing this security measure.
If you are executing JavaScript in a web browser (as indicated by "the page could be also on another domain"), alternative options may be available. For instance, if you are not limited to a browser environment, node.js provides the http client module for making HTTP requests.
To preserve the HTML tags, you may combine them with the html content in this way:
function getPageHTML() {
return "<html>" + $("html").html() + "</html>";
}
