Executing the executeScript method in Microsoft Edge using Java and WebDriverWould you like a different version?

I'm currently attempting to execute the following code in Microsoft Edge using WebDriver

ExpectedCondition<Boolean> jsLoad = driver -> ((JavascriptExecutor) driver).executeScript("return 
document.readyState").toString().equals("complete");

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

An exception is being thrown:

Exception class:org.openqa.selenium.JavascriptException

The issue stems from:

org.openqa.selenium.JavascriptException: javascript error: Function is not a constructor

We've configured EdgeOptions as follows

DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
desiredCapabilities.setBrowserName("MicrosoftEdge");
EdgeOptions edgeOptions = new EdgeOptions();
edgeOptions.setCapability("ms:inPrivate", true);
edgeOptions.setCapability("prefs", edgePrefs);
edgeOptions.setCapability("useAutomationExtension", false);
edgeOptions.merge(desiredCapabilities);
edgeOptions.setPageLoadStrategy("eager");
edgeOptions.setCapability("ms:inPrivate", true);
edgeOptions.setCapability("useAutomationExtension", false);
edgeOptions.setCapability(CapabilityType.SUPPORTS_JAVASCRIPT, true);
edgeOptions.setCapability(CapabilityType.HAS_NATIVE_EVENTS, true);
driver = new EdgeDriver(edgeOptions);

Any recommendations or suggestions?

Answer №1

executeScript()

Executing JavaScript within the current frame or window context is the purpose of this method. The provided script fragment will be executed as an anonymous function's body. In the script, 'document' can be used to refer to the current document. Keep in mind that local variables won't be accessible once the script finishes running, while global variables will persist. If the script has a return value (i.e., contains a return statement), the following actions are taken:

When dealing with an HTML element, this method returns a WebElement

If the result is a decimal, a Double will be returned

For non-decimal numerical values, a Long is returned

A boolean results in a Boolean response

All other cases lead to a String being returned.

In the case of an array, a List is returned with each object following the mentioned rules. Nested lists are supported.

In the case of a map, a Map<String, Object> is returned with values adhering to the specified rules.

If the value is null or there is no return value, then null is ultimately returned.

The arguments accepted must be a number, boolean, String, WebElement, or a List containing any combination of those types. An exception will occur if the arguments do not meet these requirements. The arguments are then passed to the JavaScript through the "arguments" magic variable, simulating a call via "Function.apply".

This Scenario

If your scenario involves waiting for document.readyState to reach complete, you can achieve this using WebDriverWait in the following manner:

new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(d => ((IJavaScriptExecutor)d).ExecuteScript("return document.readyState").Equals("complete"));
