    document.getElementById("interactiveWebCompT").innerHTML = interactiveWebComp;
    document.getElementById("interactiveWebCompMaxT").innerHTML = interactiveWebCompMax;
}
setInterval(updateAll, 100);
setInterval(basicWebCodersWork, 2000);
setInterval(interactiveWebCodersWork, 2000);
</script>
</body>
</html>

请注意save和load功能

再次注意我已尝试HTMLxp = parseInt(localStorage.HTMLxp;)，HTMLxp = localStorage.HTMLxp * 1;等等。

如果需要，您可以查看脚本/页面here

Answer 1

尝试使用var x = parseInt(localstorage.numeric)

＆＃13;

function populateStorage() {
  var obj = {x:"sdfsd", y:"sdfsdf"};
  
  localStorage.setItem('image', JSON.stringify(obj));
  console.log(localStorage.getItem('image'));
  
  localStorage.bgcolor = 'blue'
  console.log(localStorage.bgcolor);
  
  //working with numeric values
  localStorage.numeric = 3;
  console.log( parseInt(localStorage.numeric) + 1);
}

//just calling calling the funtion
var x = populateStorage.call();

＆＃13;

Answer 2

你可以将一个对象存储在本地存储中，如下所示

  Storage.prototype.setObject = function(key, value) {
    this.setItem(key, JSON.stringify(value));
}

Storage.prototype.getObject = function(key) {
    var value = this.getItem(key);
    return value && JSON.parse(value);
};


    localStorage.setObject('x', {1: 2, 2: "s"})
    console.log(localStorage.getObject('x'));

Answer 3

将localStorage中任意数字数据从字符串转换为数字的最佳方式：

var a = localStorage['some_property'];

typeof a; // "string"

var b = +localStorage['some_property'];

typeof b; // "number"

将localStorage字符串设置为Integer
