CodePudding user response：

You need to drill down into the json object to get the value you're after.

var data = '{"data":[{"product_price":"3000"}]}'

var data_json = JSON.parse( data );
console.log( data_json.data );
console.log( data_json.data[0].product_price );
document.getElementById("demo").innerHTML = data_json.data[0].product_price;
