js
element.waitFor(condition, optionsOrTimeout?)Arguments
| Argument | Type | Meaning |
|---|---|---|
condition | function | Synchronous callback receiving this query client. Return a truthy value when ready; do not return a Promise or perform actions. |
optionsOrTimeout | object | number | Optional milliseconds, or {timeout:5000, interval:100, throwOnTimeout:true}. Interval is at least 10 ms. |

Example
js
const panel = UIHelper.waitForElement({id: "panel"}, 5000);
const child = panel.waitFor(q => q.findElement({id: "ready", visible: true}), 5000);Notes
The parent must still be valid. See the matching UIHelper method for options. Placeholder panel/child identifiers require inspection.
