How to change the Text of a IWebElement of Selenium in C#

Question

The Title pretty much explains everything. I'm searching for a way to change let's say

<h1 id="title">Title<h1>

to

<h1 id="title">Nothing<h1>

I'm kind of desperate since

driver.FindElement(By.Id("title")).Text;

doesn't allow assignment.

Answer 1

Quickly glanced over the properties and methods of IWebElement, doesn't look like they can set values. However, you can easily execute some javascript snippet to change HTML in your page.

IWebDriver driver;
IJavaScriptExecutor js = driver as IJavaScriptExecutor;
js.ExecuteScript("document.getElementById("title").innerHTML = "New text!";");

You might need to escape the inner quotation marks, haven't been able to run an actual test. Or use single apostrophes.

Answer 2

I did this on Selenium Vba and it worked fine:

attrScript00 = "document.getElementById('title').innerText = 'New text2!'"
driver.ExecuteScript attrScript00

attrScript00 = "document.getElementById('title').innerHTML = 'New text3!'"
driver.ExecuteScript attrScript00
