如何使用selenium设置"value"来输入web元素？

Question

我的代码中的元素看起来像这样:

<input id="invoice_supplier_id" name="invoice[supplier_id]" type="hidden" value="">

我想设置它的值,所以我用它的xpath创建了一个web元素:

 val test = driver.findElements(By.xpath("""//*[@id="invoice_supplier_id"]"""))

但现在我没有看到设置值的选项......

Answer 1

用findElement而不是findElements

driver.findElement(By.xpath("//input[@id='invoice_supplier_id'])).sendKeys("your value");

要么

WebElement element = driver.findElement(By.xpath("enter the xpath here")); // you can use any locator
 JavascriptExecutor jse = (JavascriptExecutor)driver;
 jse.executeScript("arguments[0].value='enter the value here';", element);

要么

(JavascriptExecutor) driver.executeScript("document.evaluate(xpathExpresion, document, null, 9, null).singleNodeValue.innerHTML="+ DesiredText);

希望它能帮到你:)

Answer 2

driver.findElement(By.id("invoice_supplier_id")).setAttribute("value", "your value");
