Issue with IE preventing Selenium from triggering Onchange event and causing page to fail to Postback

I am currently working on a web application where selecting an item from one drop-down list triggers the loading of another. However, when using Selenium to automate this process, I have encountered an issue where the page post back is prevented and the second drop-down does not get loaded. Below are the codes I have tried, including attempting to trigger the onchange event:

WebElement selectElement = driver.findElement(By.name("ctrlFundTransfer$dropDownListWrittingCompany"));

String change=selectElement.getAttribute("onchange");

System.out.println("List Item " + change);

Select selectw = new Select(selectElement);

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("alert(\"Executing\");"+change+";");

If anyone has insight into how to manage the page postback process in order to successfully load the second drop-down while using Selenium, your assistance would be greatly appreciated.

Answer №1

The problem was identified as being related to GZIP compression. Disabling it allowed the situation to be resolved.

For Internet Explorer users, navigating to 'Tools', 'Internet Options', 'Advanced', and then unchecking both settings under 'HTTP 1.1 Settings' helped in successfully running the page.
