CloudSponge - Example React Component
import React from 'react'
// Simple React Component that manages adding the cloudsponge object to the page
// and initializing it with the options that were passed through.
// props:
// * cloudspongeKey (required): your widget key from your CloudSponge account https://app.cloudsponge.com/app
// * options (optional): any javascript options you wish to pass to configure the cloudpsonge object
//
// For example, you can use the component like so:
// import CloudSpongeWidget from './CloudSpongeWidget'
// // react boilerplate ...
// <CloudSpongeWidget
// cloudspongeKey="localhost-only"
// options={{
// selectionLimit: this.availableNewUserSlots.bind(this),
// afterSubmitContacts: this.addUsers.bind(this),
// }}
// >
// <a className="cloudsponge-launch" data-cloudsponge-source="gmail">
// Add your Gmail Contacts
// </a>
// <a className="cloudsponge-launch">
// Add From Address Book
// </a>
// </CloudSpongeWidget>
class CloudSpongeWidget extends React.Component {
// adds an async script tag to the page and invokes a callback when the script has loaded
addJavascript(src, id, callback) {
if (id && document.getElementById(id)) {
// the script is already loaded so just invoke the callback and return
callback & callback()
return
}
// create and add the scrpt tag
const scriptTag = document.createElement('script')
scriptTag.type = 'text/javascript'
scriptTag.async = 1
if (id) {
scriptTag.id = id
}
// set the script to invoke a callback after it loads
if (callback) {
if (scriptTag.readyState) { // IE7+
scriptTag.onreadystatechange = () => {
if (scriptTag.readyState == 'loaded' || scriptTag.readyState == 'complete') {
// clear the callback so it only ever executes once
scriptTag.onreadystatechange = null
callback()
}
}
}
else {
scriptTag.onload = () => { // Other browsers support the onload attribute \o/
callback()
}
}
}
// assign the src attribute
scriptTag.src = src
// add the script to the page
document.body.appendChild(scriptTag)
}
componentDidMount() {
this.addJavascript(`https://api.cloudsponge.com/widget/${this.props.cloudspongeKey}.js`, "__cloudsponge_widget_script", () => {
// calling init attaches the cloudsponge.launch action to any cloudsponge-launch links on the page
// we need to wait until the script has loaded so we aren't "bandwidthist"
if (window.cloudsponge) {
cloudsponge.init(this.props.options)
}
})
}
// just render the children, if any.
// typically the children will include at least one link decorated with
// class="cloudsponge-launch" so that the cloudsponge library will attach
// to its onClick handler to launch the widget
render() {
return this.props.children
}
}
export default CloudSpongeWidget

line 44 - 59:
I think that the else statement should be nested in the if(callback) block instead of outside of it.

if (callback) {
  if (scriptTag.readyState) { // IE7+
    scriptTag.onreadystatechange = () => {
      if (scriptTag.readyState == 'loaded' || scriptTag.readyState == 'complete') {
        // clear the callback so it only ever executes once
        scriptTag.onreadystatechange = null
        callback()
      }
    }
  }
  else {
      scriptTag.onload = () => { // Other browsers support the onload attribute \o/
      callback()
    }
  } 
}
