How to take element by javascript.

[Anton]

Hello,

Is it possible?
I try to use 

Actions.InvokeScript<HtmlSpan>(
                "$j('#rulesTree span.rf-trn-lbl')" +
                ".filter(function() " +
                "{return $j(this).text().trim() == 'er';})").Click();

But take exception:

• • • • • • Object reference not set to an instance of an object.

Hello Anton,

Unfortunately you can't do it in this direct way. InvokeScript is invoking functions.

Please implement your code in a function in the html application and call the Click() event in there.

Then call the functions using InvokeScript:

Actions.InvokeScript("myFunction()");

I recorded a short video as a demonstration.

Hope this helps.
Kind regards,

Hello Boyan.

Thanks for answer.

I think that it will be great if WebAii can take element by invoked javascript.

Hi Anton,

Unfortunately the types that can be returned are strictly typed and can only be basic C# types, bool, int, string, etc. 

Should you have any additional questions please do not hesitate to contact us again.

As i understand, it is limitation of WebAii? Because this feature is implemented in WebDriver (Selenium 2).
