Set Up the Project Structure

In this step, you will set up the project files and structure. Follow the steps below to complete this step:

Open the project folder. The directory structure is as follows:

├── element-ui.css
├── element-ui.js
├── index.html
└── vue.js

Click on Go Live button in the bottom right corner of WebIDE, to run the project.

Next, open "Web 8080" on the top of the VM and refresh it manually and you will see the page.

In this step, you will implement the functionality to convert between dates and timestamps.

  1. Locate the handleTransform() method in the Vue.js instance.

  2. Inside the handleTransform() method, you need to add the logic to convert between dates and timestamps.

  3. If the formInline.date is not empty and the formInline.timeStamp is empty, you should convert the date value to a 13-digit timestamp and update the formInline.timeStamp accordingly.

    let date = this.formInline.date;
    let timeStamp = this.formInline.timeStamp;
    if (date && !timeStamp) {
      let newValue = new Date(date);
      this.formInline.timeStamp = newValue.getTime();
    }
  4. If the formInline.date is empty and the formInline.timeStamp is not empty, you should convert the timestamp value to a date string in the format YYYY-MM-DD hh:mm:ss and update the formInline.date accordingly.

    if (!date && timeStamp) {
      timeStamp = new Number(timeStamp);
      let d = new Date(timeStamp);
      var Y = d.getFullYear() + "-";
      var M =
        (d.getMonth() + 1 < 10 ? "0" + (d.getMonth() + 1) : d.getMonth() + 1) +
        "-";
      var D = d.getDate() < 10 ? "0" + d.getDate() + " " : d.getDate() + " ";
      var H = d.getHours() + ":";
      var M2 =
        (d.getMinutes() < 10 ? "0" + d.getMinutes() : d.getMinutes()) + ":";
      var S = d.getSeconds() < 10 ? "0" + d.getSeconds() : d.getSeconds();
      this.formInline.date = Y + M + D + H + M2 + S;
    }
  5. The full code is below:

    handleTransform() {
       // TODO
       let date = this.formInline.date;
       let timeStamp = this.formInline.timeStamp;
       if (date && !timeStamp) {
         let newValue = new Date(date);
         this.formInline.timeStamp = newValue.getTime();
       }
       if (!date && timeStamp) {
         timeStamp = new Number(timeStamp);
         let d = new Date(timeStamp);
         var Y = d.getFullYear() + "-";
         var M =
           (d.getMonth() + 1 < 10
             ? "0" + (d.getMonth() + 1)
             : d.getMonth() + 1) + "-";
         var D =
           d.getDate() < 10 ? "0" + d.getDate() + " " : d.getDate() + " ";
         var H = d.getHours() + ":";
         var M2 =
           (d.getMinutes() < 10 ? "0" + d.getMinutes() : d.getMinutes()) +
           ":";
         var S =
           d.getSeconds() < 10 ? "0" + d.getSeconds() : d.getSeconds();
         this.formInline.date = Y + M + D + H + M2 + S;
       }
    }
  6. Save the index.html file and refresh the web page. Test the conversion functionality by entering or selecting a date and time, and then clicking the "convert" button.

Verify the Conversion Results

In this step, you will verify that the conversion between dates and timestamps is working as expected.

  1. Open the web page and observe the conversion results.
  2. When you enter or select a date and time in the date-time picker, the timestamp input box should display the corresponding 13-digit timestamp.
  3. When you enter a 13-digit timestamp in the timestamp input box, the date-time picker should display the correct date and time.
  4. Ensure that the date format is displayed as YYYY-MM-DD hh:mm:ss and the timestamp is 13 digits long.
  5. Test the conversion in both directions to ensure it's working correctly.
