Wait for an element to exist on the page with jQuery

wait-el.js

var waitForEl = function(selector, callback) {
  if (jQuery(selector).length) {
    callback();
  } else {
    setTimeout(function() {
      waitForEl(selector, callback);
    }, 100);
  }
};

waitForEl(selector, function() {
  // work the magic
});

Works very well! Thank you! You are a life saver to my project

Thank you!
I set maxTimes to 100. After 100 tries, it will stop.

jQuery(document).ready(function () {
    var selector = '#element';
  
    var waitForEl = function (selector, callback, maxTimes = false) {
      if (jQuery(selector).length) {
        callback();
      } else {
        if (maxTimes === false || maxTimes > 0) {
          maxTimes != false && maxTimes--;
          setTimeout(function () {
            waitForEl(selector, callback, maxTimes);
          }, 100);
        }
      }
    };
  
    waitForEl(selector, function () {
        jQuery(selector); // do something with selector
    }, 100);
});
