Getting notified when a block is found on pool.sumokoin.ch

snippet.js

$('#poolLastBlockFound').on('DOMSubtreeModified', function(x) {
    var blockFoundText="1 minute";
    if (x.target.innerHTML.includes(blockFoundText)) {
        alert('Block found!');
    }
})

// OR

var elementId = "poolLastBlockFound";
var stringToFind = "1 minute ago";

function containsBlock(value) {
  return value.indexOf(stringToFind) != -1;
}

function blockFoundIn(elements) {
  for(var adjustedNode of elements) {
    if (containsBlock(adjustedNode.textContent)) {
      return true;
    }
  }
  return false;
}

var element = document.getElementById(elementId);
var config = { attributes: true, attributeOldValue: true,  childList: true };

// Callback function to execute when mutations are observed
var callback = function(mutationsList) {
  for(var mutation of mutationsList) {
    if (mutation.type == 'childList') {
      var blockFound = blockFoundIn(mutation.addedNodes);
      blockFound &= !blockFoundIn(mutation.removedNodes);
    }
    
    if (blockFound) {
      alert('We found a block!');
    }
  }
};

// Create an observer instance linked to the callback function
var observer = new MutationObserver(callback);

// Start observing the target node for configured mutations
observer.observe(element, config);
