Collect statistics on the use of open source

TOAST UI Placeholder applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI Placeholder is used throughout the world. It also serves as important index to determine the future course of projects. location.hostname (e.g. > “ui.toast.com") is to be collected and the sole purpose is nothing but to measure statistics on the usage. To disable GA, use the following usageStatistics option when creating the instance.

var options = {
    ...
    usageStatistics: false
};

placeholder.generate(targets, options);

Or, include tui-code-snippet(v1.5.0 or later) and then immediately write the options as follows:

tui.usageStatistics = false;

import placeholder from 'tui-placeholder'; /* ES6 */

Then you should call the generate method with options to create virtual placeholders.

var targets = document.getElementByTags('input');

placeholder.generate(targets, { ... });
