Convery string to typescript object type-CodePudding

I need to store chart configuration in DB calling API. Next time I get that config as a string from DB and I need to convert it to object type. For some reason data conversion does not work, and I'm confused why.

The result in console is this:

But actually, result should be like this:

Does someone know some trick on how to convert string to type?

CodePudding user response：

Your string is not valid json syntax. Make sure your string is valid. After that you can parse it to typescript object using this:

JSON.parse("your valid string source")

Finnaly I found the way:

var obj = `{
      xAxis: {
        type: 'category',
        data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
      },
      yAxis: {
        type: 'value'
      },
      series: [
        {
          data: [150, 230, 224, 218, 135, 147, 260],
          type: 'line'
        }
      ]
    }`;
    obj = obj.replace(/'/g, '"');

    var jsonStr = obj.replace(/(\w :)|(\w  :)/g, function (matchedStr) {
      return '"'   matchedStr.substring(0, matchedStr.length - 1)   '":';
    });

    obj = JSON.parse(jsonStr); //converts to a regular object
    // After you have JSON you can cast it to your own object type
    console.log(obj);
