https://idiotwu.me/understanding-es6-promise/
// returns an ordered-list of headers in page content
var toc = initTOC(options);
// then you can append it to anywhere you like
elem.appendChild(toc);// will append TOC list to target element
$(elem).initTOC(options);initTOC({
selector: 'h1, h2, h3, h4, h5, h6',
scope: 'body',
overwrite: false,
prefix: 'toc'
});String:selector: headers selector, default is'h1, h2, h3, h4, h5, h6'.String:scope: selector to specify elements search scope, default is'body'.Boolean:overwrite: whether to overwrite existed headers' id, default isfalse, which means plugin will preserve the existed id property and create a string liketoc-1for those don't have id assigned.String:prefix: string to prepend to id/href property, default is'toc', which generates a string liketoc-0. Set totrueto generate an automatic prefix based on the title.
