My code :

WebDriver driver = DriverFactory.getWebDriver()

WebElement c = driver.findElement(By.xpath(’//*[@id=“mobile”]’))

((JavascriptExecutor) DriverFactory.getWebDriver()).executeScript(“showMobileProductInfo()=” + device + “”,c)


"showMobileProductInfo()=" + device + ""

is not a legal JavaScript assignment expression. You are trying to assign the value of device to the result a call to a function, which is not possible (or even sensible).

In addition, you’ll find it easier to use webUI.executeJavaScript.

Finally, what does this have to do with onchange?

Hi Russ
thanks for the answer…

i tried webUI.executeJavaScript. but i got the error

This is my code:

WebElement element = WebUiCommonHelper.findWebElement(findTestObject(‘Sale/BindingPeriod’), 30)

WebUI.executeJavaScript(‘getAdditions(); getDeviceListPrice();’, element)


Test Cases/SE_DSL_Consumer FAILED because (of) groovy.lang.MissingMethodException: No signature of method: static com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords.executeJavaScript() is applicable for argument types: (java.lang.String, org.openqa.selenium.remote.RemoteWebElement) values: [getAdditions(); getDeviceListPrice();, [[CChromeDriver: chrome on XP (8ed90f1de16586732ff81a7fb02083c8)] -> xpath: //*[@class = ‘shortoptions’ and @name = ‘bindingPeriod’ and @id = ‘bindingPeriod’]]]

Possible solutions: executeJavaScript(java.lang.String, java.util.List), executeJavaScript(java.lang.String, java.util.List, com.kms.katalon.core.model.FailureHandling)

The second argument to executeJavaScript must be a list:

WebUI.executeJavaScript(‘getAdditions(); getDeviceListPrice();’, Arrays.asList(element))
