ui.util.debounce
Stay organized with collections
Save and categorize content based on your preferences.
Wraps a function to allow it to be called, at most, once for each sequence of calls fired repeatedly so long as they are fired less than a specified interval apart (in milliseconds). This can be used to reduce the number of invocations of an expensive function while ensuring it eventually runs.
Example use: For the callback to a change event on a ui.Checkbox. If the user clicks the checkbox repeatedly, only the last click of the checkbox will run the callback.
Returns the debounced function.
| Usage | Returns | ui.util.debounce(func, delay, scope) | Function |
| Argument | Type | Details | func | Function | The function to debounce. |
delay | Number | After the function is called once, the number of milliseconds to delay for an additional invocation of the function before allowing it to run. |
scope | Object, optional | Object in whose scope to call the function. |
