EvaluateExpressionAsync(string)

Executes a script in browser context.

Task<JToken> EvaluateExpressionAsync(string script)

Parameters

script string

Script to be evaluated in browser context.

Returns

Task<JToken>

Task which resolves to script return value.

Remarks

If the script, returns a Promise, then the method would wait for the promise to resolve and return its value.

Type Parameters

T

The type to deserialize the result to.
