javascript error: Cannot read properties of undefined (reading 'element')-CodePudding

I am trying to run the following code:

WebElement body = driver.findElement(By.xpath("/html/body"));
js.executeScript("var injector = window.angular.element(argument[0]).injector(); var $http = injector.get('$http'); return ($http.pendingRequests.length === 0);",body);

I however get the following error:

Can you please let me know how i could resolve this issue?

CodePudding user response：

Since you want to get arguments list element by index try to replace

argument[0]

with

arguments[0]

CodePudding user response：

@suhail shaik You can try the following, assuming you want to check if all the pending $http requests are served by Angular in the background.

  String angularReady = "return angular.element(document).injector().get('$http').pendingRequests.length === 0";

  boolean isAngularReady = (boolean)js.executeScript(angularReady);
