硒不触发IE中的Onchange，并且不允许页面回发

Question

I have a web Application, where Once we select a drop down list the other one get loaded. Here with selenium once the drop down is selected, the page post back gets stopped and the second drop down does not get loaded. I have used the following codes. I even tried triggering the on 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+";");

Kindly tell how to go about that page postback process for loading the second drop down as Selenium i preventing the page postback.

The issue was with GZIP compression. You may disable it and work.

When in IE if I goto 'Tools', 'Internet Options', 'Advanced', then under 'HTTP 1.1 settings' uncheck both settings and run the page, it works.
