如何清除文本框中的文本？

Question

webdriver clear() is not clearing the existing text

I have tried clear() and it's not working, so tried .sendKeys(Keys.chord(Keys.CONTROL, "a", Keys.BACK_SPACE)) but my senior doesn't want me to use the keys. So unsure how can i clear the text?

HTML of the element:

<input name="Quantity_110787" type="number" min="0" ng-model="invoiceLine.quantity" class="form-control ng-pristine ng-valid ng-not-empty ng-valid-min ng-touched" ng-keypress="$ctrl.preventKey($event)" aria-invalid="false">

Code trials:

public void sendText(String text) {
        for (String control : controls) { 
        if(getWebDriver().findElement(By.cssSelector(control)).getAttribute("type").contains("number")) {
                getWebDriver().findElement(By.cssSelector(control)).sendKeys(Keys.chord(Keys.CONTROL, "a", Keys.BACK_SPACE), text);
                break;
            }
        }

I want the text field to be cleared, so i can enter the new text. Please help.

Answer 1

This should work as @Dark Knight said,

driver.findElement("locator").clear();

try to click before

 driver.findElement("locator").click();
 driver.findElement("locator").clear();

else try using sendKeys

driver.findElement("locator").click();
driver.findElement("locator").sendKeys("");

else try JS:

WebElement wb = driver.findElement("locator");
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("arguments[0].value='';", wb);

Thanks,

尝试这样做。

driver.findElement("locator").clear();

The desired element is a Angular element so to invoke clear() method you need to induce WebDriverwait for the element to be clickable and you can use either of the following solutions:

• cssSelector :

   WebElement elem = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.form-control.ng-pristine.ng-valid.ng-not-empty.ng-valid-min.ng-touched[type='number'][name^='Quantity_']"))); elem.click(); elem.clear(); 

• xpath :

   WebElement elem = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='form-control ng-pristine ng-valid ng-not-empty ng-valid-min ng-touched' and @type='number'][starts-with(@name, 'Quantity_')]"))); elem.click(); elem.clear();
