Implement this, Its working for many of us including me. It includes Web Page wait on JavaScript, Angular, JQuery if its there.

If your Application is containing Javascript & JQuery you can write code for only those,

By define it in single method and you can Call it anywhere:

          // Wait for jQuery to load
          {             
            ExpectedCondition jQueryLoad = driver -> ((Long) ((JavascriptExecutor) driver).executeScript("return jQuery.active") == 0);

            boolean jqueryReady = (Boolean) js.executeScript("return jQuery.active==0");

            if (!jqueryReady) {
                // System.out.println("JQuery is NOT Ready!");
                wait.until(jQueryLoad);
            }
            wait.until(jQueryLoad);
          }

          // Wait for ANGULAR to load
          {               
            String angularReadyScript = "return angular.element(document).injector().get('$http').pendingRequests.length === 0";

            ExpectedCondition angularLoad = driver -> Boolean.valueOf(((JavascriptExecutor) driver).executeScript(angularReadyScript).toString());

            boolean angularReady = Boolean.valueOf(js.executeScript(angularReadyScript).toString());

            if (!angularReady) {
                // System.out.println("ANGULAR is NOT Ready!");
                wait.until(angularLoad);
            }
          }

          // Wait for Javascript to load    
          {             
            ExpectedCondition jsLoad = driver -> ((JavascriptExecutor) driver).executeScript("return document.readyState").toString()
                    .equals("complete");

            boolean jsReady = (Boolean) js.executeScript("return document.readyState").toString().equals("complete");

            // Wait Javascript until it is Ready!
            if (!jsReady) {
                // System.out.println("JS in NOT Ready!");
                wait.until(jsLoad);
            }
          }

Let me know if you stuck anywhere by implementing.

It overcomes the use of Thread or Explicit Wait.
