I am trying to see how to use reg expressions to replace a url up to the .com, with something like local host. I am not a guru with expressions, so having a lot of troubles doing this. It is so we can have a Chrome extension for our localhost, and swap all urls to point to local host for debugging. So the expression needs to find anything like the following:
*.com/ --> and beyond stays the same, but up to the .com is swapped with our temp string value.
Thanks in advance
if you want to use chrome extension then * is valid
chrome.webRequest.onBeforeRequest.addListener(
function(details) {
details.url = "http://localhost";
},
{urls: ["*://*.*.com/*"]}, //could also be urls: ["*://my.host.com/*"]
//also if you want to change all urls you can use ["<all_urls>"]
["blocking"]);
You should be able to accomplish it with this if you want to go the regex route:
.*?(?=\.com\b)

It uses a positive lookahead to match up until the .com.
here is the fiddle: https://jsfiddle.net/520zdnsL/
url = url.replace(/^.+?\.com\b/i, 'http://localhost');
