A script to select multiple history entries (in Chrome) that match against a given string — handy for bulk deletions

chrome-history-select-bulk.js

// Go to chrome://history-frame and run the following script from the console:

var url = window.prompt('Enter a URL to match');
var entries = document.querySelectorAll('.entry');
Array.prototype.forEach.call(entries, function (entry) {
  var test = new RegExp(url)
  if (test.exec(entry.querySelector('.title a').attributes.getNamedItem('href').value)) {
    entry.querySelector('input[type="checkbox"]').checked = true;
  }
});
