What is the best way to ensure an element is clickable in WebDriverJS before proceeding?

Is there a way to wait for a WebElement to be clickable in WebDriverJS? I am familiar with waiting for the element to be "visible", but need it to be "clickable". Is there an equivalent of expected conditions in Python binding available in Webdriver Js API?

Answer №1

Python's

selenium.webdriver.support.expected_conditions.element_to_be_clickable
does not have an equivalent condition in this context. However, upon examining the source code of that condition, it appears to perform two checks:

  1. Checking if the element is visible.

  2. Verifying if the element is enabled.

In order to achieve a similar functionality, one can wait for both of these conditions to be met. The provided code snippet demonstrates how this can be implemented. It involves making an element invisible and disabled initially, setting timeouts to make it visible and enabled, and then waiting for the desired conditions.

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
   withCapabilities(webdriver.Capabilities.chrome()).
   build();

driver.get('http://www.google.com');

// The following script showcases testing the wait operation. Initially, we make the element invisible
// and disable it. Subsequently, we set timeouts to ensure its visibility and enablement.
driver.executeScript("\
var q = document.getElementsByName('q')[0];\
q.style.display = 'none';\
q.disabled = true;\
setTimeout(function () {\
    q.style.display = '';\
}, 2000);\
setTimeout(function () {\
    q.disabled = false;\
}, 3000);\
");
driver.findElement(webdriver.By.name('q')).then(function (element) {
    driver.wait(function () {
        return element.isDisplayed().then(function (displayed) {
            if (!displayed)
                return false;

            return element.isEnabled();
        });
    });
    element.sendKeys('webdriver');
});
driver.findElement(webdriver.By.name('btnG')).click();
driver.wait(function() {
 return driver.getTitle().then(function(title) {
   return title === 'webdriver - Google Search';
 });
}, 1000);

driver.quit();

The structure of the code may appear unfamiliar due to the asynchronous nature of promises. While promises are not inherently complex, they might require some time for adaptation especially for those accustomed to working with Python.

Answer №2

If you have no interest in clicking the object once it becomes available, here is an alternative approach:

function clickWhenClickable(locator, timeout){
  driver.wait(function(){
    return driver.findElement(locator).then(function(element){
      return element.click().then(function(){
        return true;
      }, function(err){
        return false;
      })
    }, function(err){
      return false;
    });
  }, timeout, 'Timeout waiting for ' + locator.value);    ;
}

If your goal is simply to verify if the element is clickable without actually clicking it, then this code may not be suitable for your needs. As of now, WebDriver JS may not offer a direct method for achieving this functionality. (If there are any insights on this matter, they are welcome)
