(function () {

var input = document.getElementsByTagName('input')[0]

var origin = document.getElementsByClassName('markdown-body')[0].innerHTML;

input.addEventListener('keyup', function () {

var searchKey = input.value

console.log('keyup', searchKey)

document.getElementsByClassName('markdown-body')[0].innerHTML =

origin.replace(searchKey, '' + searchKey + '')

})

}())
