I coded a template that pushes values from a SharePoint List into an array. I want to change the image inside the array depending on a value that is inside an array.

The value should function like a traffic light function. So if the value is "Green", the template should use a green traffic light image. If "Yellow" then a yellow image.

Here is my code so far:

public render(): React.ReactElement<IWebPartPoCswProps> {
    const {
    } = this.props;
    let project =[];
    this.state.ProjectFilterItem.forEach((item:IListItem)=> project.push(
      <div className={styles.containerGrid}>
        <div className={styles.ProjectTitleHeader}>item 1 {item.Title}</div>
        <div className={styles.ProjectStatusTrafficLight}>item 2 TrafficLight {item.TrafficLight?.Title}</div>
        <div className={styles.ProjectStartdate}>item 3 {item.StartDate}</div>
        <div className={styles.ProjectEnddate}> item 4 {item.EndDate}</div>
        <div className={styles.ProjectStatus}>item 5 {item.ProjectStatus?.Title}</div>
        <div className={styles.ProjectPhase}>item 6 {item.ProjectPhase?.Title}</div>

    return (
      <section className={`${styles.webPartPoCsw} ${hasTeamsContext ? styles.teams : ''}`}>
        <div className={styles.welcome}>
          <h2>Well done, {escape(userDisplayName)}!</h2>
          <div>Web part property value: <strong>{escape(description)}</strong></div>

I can't read the value of the TrafficLight array position. Maybe you can help me. e.g.

If (ValueTrafficlight =="Green"){
      valueLight="Green url"
  • Is TrafficLight of type array? Is it nested inside ProjectFilterItem? Sep 26, 2022 at 13:41
  • Yes. You can get the value from this line: {item.TrafficLight?.Title} here is the value Green, Yellow or Red

  • Then what is the problem exactly? Are you unable to use If (item.TrafficLight && item.TrafficLight.Title == "Green"){ }. From where the image URL will be coming, dynamically or static URLs hard coded? Sep 26, 2022 at 13:55
  • I don't know how to use conditional rendering in my template. That's my problem.

You can use conditional rendering in template like this:

    if (item.TrafficLight && item.TrafficLight.Title == "Green") {
        return <img src="green.jpg" />
    } else if (item.TrafficLight && item.TrafficLight.Title == "Yellow") {
        return <img src="yellow.jpg" />
    } else {
        return <img src="red.jpg" />

You can change the image URLs as per your requirements.

  • That's not working for me. I needs to be different, but still figure out how.

  • Can you explain in details how you want it? Reference links in my answer does not help you with conditional rendering? There are multiple ways to achieve conditional rendering in react, read the articles in above links once. Sep 27, 2022 at 7:29
  • Is it working for you now? You can also try switch or ternary operator approach from 3rd link in my answer. let me know if you still need help with this. Sep 27, 2022 at 13:54
  • Please update this thread, is it working for you now? Aug 3, 2023 at 11:52
