Parameters

expression

Type: SystemString
Expression to evaluate.

objectGroup (Optional)

Type: SystemString
Symbolic group name that can be used to release multiple objects.

includeCommandLineAPI (Optional)

Type: SystemNullableBoolean
Determines whether Command Line API should be available during the evaluation.

silent (Optional)

Type: SystemNullableBoolean
In silent mode exceptions thrown during evaluation are not reported and do not pauseexecution. Overrides `setPauseOnException` state.

contextId (Optional)

Type: SystemNullableInt32
Specifies in which execution context to perform evaluation. If the parameter is omitted theevaluation will be performed in the context of the inspected page.

returnByValue (Optional)

Type: SystemNullableBoolean
Whether the result is expected to be a JSON object that should be sent by value.

generatePreview (Optional)

Type: SystemNullableBoolean
Whether preview should be generated for the result.

userGesture (Optional)

Type: SystemNullableBoolean
Whether execution should be treated as initiated by user in the UI.

awaitPromise (Optional)

Type: SystemNullableBoolean
Whether execution should `await` for resulting value and return once awaited promise isresolved.

throwOnSideEffect (Optional)

Type: SystemNullableBoolean
Whether to throw an exception if side effect cannot be ruled out during evaluation.This implies `disableBreaks` below.

timeout (Optional)

Type: SystemNullableInt64
Terminate execution after timing out (number of milliseconds).

disableBreaks (Optional)

Type: SystemNullableBoolean
Disable breakpoints during execution.

replMode (Optional)

Type: SystemNullableBoolean
Setting this flag to true enables `let` re-declaration and top-level `await`.Note that `let` variables can only be re-declared if they originate from`replMode` themselves.

allowUnsafeEvalBlockedByCSP (Optional)

Type: SystemNullableBoolean
The Content Security Policy (CSP) for the target might block 'unsafe-eval'which includes eval(), Function(), setTimeout() and setInterval()when called with non-callable arguments. This flag bypasses CSP for thisevaluation and allows unsafe-eval. Defaults to true.
