.clearValue() Suggest edits


Clear a textarea or a text input element's value. Starting with v1.1 clearValue() will wait for the element to be present (until the specified timeout).

If the element is not found, an error is thrown which will cause the test to fail. Starting with v1.2 you can suppress element not found errors by specifying the suppressNotFoundErrors flag.

clearValue() will automatically wait for the element to be present (until the specified timeout). If the element is not found, an error is thrown which will cause the test to fail. Starting with v1.2 you can suppress element not found errors by specifying the suppressNotFoundErrors option.

Usage

.clearValue(selector, [callback])
.clearValue(using, selector, [callback])

Parameters

Name Type description
using
Optional		 string

The locator strategy to use. See W3C Webdriver - locator strategies
selector string|object

The selector (CSS/Xpath) used to locate the element. Can either be a string or an object which specifies element properties.
callback
Optional		 function

Optional callback function to be called when the command finishes.

Example

module.exports = {
  demoTest(browser) {
    browser.clearValue('#login input[type=text]');

    browser.clearValue('#login input[type=text]', function(result) {
      console.log('clearValue result', result);
    });

    // with explicit locate strategy
    browser.clearValue('css selector', '#login input[type=text]');

    // with selector object - see https://nightwatchjs.org/guide#element-properties
    browser.clearValue({
      selector: '#login input[type=text]',
      index: 1,
      suppressNotFoundErrors: true
    });

    browser.clearValue({
      selector: '#login input[type=text]',
      timeout: 2000 // overwrite the default timeout (in ms) to check if the element is present
    });
  }
}

Examples

The example below navigates to google.com, searches for the term "nightwatch.js", then clears the input using clearValue command and finally verifies if the results container is empty:


module.exports = {
  before : function(browser) {
    // see https://github.com/nightwatchjs/nightwatch/blob/main/examples/globalsModule.js#L12
    browser.globals.waitForConditionTimeout = 5000;
  },

  'clearValue example test' : function (browser) {

    browser
      .url('https://google.com')
      .waitForElementVisible('input[type=text]')
      .setValue('input[type=text]', 'nightwatch.js')
      .click('button[type=submit]')
      .expect.element('#rcnt').text.to.contain('nightwatchjs.org/');

    browser
      .clearValue('input[type=text]')
      .expect.element('#rcnt').text.to.equal('');
  },

  after : function(browser) {
    browser.end();
  }
};

Output
