import React, { Component } from 'react'
import { render } from 'react-dom'

class OkButton extends Component {
  componentWillMount() {

    const scriptOk = document.createElement('script')
    
    scriptOk.innerHTML = `
      !function (d, id, did, st, title, description, image) {	
        var js = d.createElement("script");
        js.src = "https://connect.ok.ru/connect.js";
        js.onload = js.onreadystatechange = function () {
        if (!this.readyState || this.readyState == "loaded" || this.readyState == "complete") {
          if (!this.executed) {
            this.executed = true;
            setTimeout(function () {
              OK.CONNECT.insertShareWidget(id,did,st, title, description, image);
            }, 0);
          }
        }};
        d.documentElement.appendChild(js);
      }(document,"ok_shareWidget","https://todayme.ru",'{"sz":30,"st":"oval","ck":1}',"","","");
    `

    document.head.append(scriptOk)
  }

  render() {
    return <div id="ok_shareWidget"></div>
  }
}

class App extends Component {
  render() {
    return <div>
      OK example
      <OkButton></OkButton>	
    </div>
  }
}

render(
  <App />,
  document.querySelector('#mount_place')
)
