If you know the class name of the loader, you just can add the below code snippet (for c#):
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(seconds));
var waiter = wait.Until(ExpectedConditions.InvisibilityOfElementLocated(By.ClassName(cssClass)));
return waiter;
You just need to wait for jquery to finish its job. Here's a sample java implementation of the solution that I have come up.
I don't use WebDriverWait as I must define a TimeOut. This script will wait for the jquery to finish its job even if it takes 10 minutes. I have tried this in a demo website where I preconfigured a hard coded wait of 7 minutes. And It worked for me.
//Wait for JQuery Load
public static void waitForJQueryLoad() {
//Wait for jQuery to load
ExpectedCondition<Boolean> jQueryLoad = driver -> ((Long) ((JavascriptExecutor) jsWaitDriver)
.executeScript("return jQuery.active") == 0);
//Get JQuery is Ready
boolean jqueryReady = (Boolean) jsExec.executeScript("return jQuery.active==0");
//Wait JQuery until it is Ready!
if(!jqueryReady) {
System.out.println("JQuery is NOT Ready!");
//Wait for jQuery to load
jsWait.until(jQueryLoad);
} else {
System.out.println("JQuery is Ready!");
}
}
If it's something other than JQuery. Just take a look at the sample provided in that web site(https://www.swtestacademy.com/selenium-wait-javascript-angular-ajax/). You may end up with Angular, JQuery and XHR request solutions also.
