How to get DOM element by JavaScript GetElementsByClassName in Playwright-Sharp?

[zydjohnHotmail]

Hello: I am rather new to Playwright-Sharp, I need to run some very simple JavaScript in Playwright-Sharp. document.getElementsByClassName('class1')[0].click(); sleep 1 second; document.getElementsByClassName('class2')[0].value = 1; then move focus from document.getElementsByClassName('class2')[0] to other DOM elements. For sleeping 1 second, I can use some JavaScript Promise, but how to move focus after setting an input element value, I don’t know yet. Please show me how I can do this by Playwright-Sharp (version 0.192.0) I searched around, I only see something like for select DOM element: page.WaitForSelectorAsync('#id1'); But this code doesn’t work in my case, as there is no ID# in the whole web page. I have to use getElementsByClassName. By the way, there is no example code on how to set value for an input element. Please advise,

Class names can be used in the CSS selector: https://playwright.dev/dotnet/docs/selectors Input can be set as follows:

await page.EvalOnSelectorAsync<string>("class-name", "(i, value) => i.value = value", "VALUE");
