If the parameter is omitted the evaluation will be performed in the context of the inspected page. | | [disableBreaks](./puppeteer.protocol.runtime.evaluaterequest.disablebreaks.md) | boolean | Disable breakpoints during execution. | | [expression](./puppeteer.protocol.runtime.evaluaterequest.expression.md) | string | Expression to evaluate. | | [generatePreview](./puppeteer.protocol.runtime.evaluaterequest.generatepreview.md) | boolean | Whether preview should be generated for the result. | | [includeCommandLineAPI](./puppeteer.protocol.runtime.evaluaterequest.includecommandlineapi.md) | boolean | Determines whether Command Line API should be available during the evaluation. | | [objectGroup](./puppeteer.protocol.runtime.evaluaterequest.objectgroup.md) | string | Symbolic group name that can be used to release multiple objects. | | [replMode](./puppeteer.protocol.runtime.evaluaterequest.replmode.md) | boolean | 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. | | [returnByValue](./puppeteer.protocol.runtime.evaluaterequest.returnbyvalue.md) | boolean | Whether the result is expected to be a JSON object that should be sent by value. | | [silent](./puppeteer.protocol.runtime.evaluaterequest.silent.md) | boolean | In silent mode exceptions thrown during evaluation are not reported and do not pause execution. Overrides setPauseOnException state. | | [throwOnSideEffect](./puppeteer.protocol.runtime.evaluaterequest.throwonsideeffect.md) | boolean | Whether to throw an exception if side effect cannot be ruled out during evaluation. This implies disableBreaks below. | | [timeout](./puppeteer.protocol.runtime.evaluaterequest.timeout.md) | [TimeDelta](./puppeteer.protocol.runtime.timedelta.md) | Terminate execution after timing out (number of milliseconds). | | [userGesture](./puppeteer.protocol.runtime.evaluaterequest.usergesture.md) | boolean | Whether execution should be treated as initiated by user in the UI. |
