如何调用函数选定的次数？

Question

我正在尝试运行函数 getOrderData 用户在下拉列表中选择的次数，我该怎么做？

玉档：

p
strong Number of pieces:
select(id='numOfPieces')

Javascript 文件:

function getOrderData() {
      //this just creates the dropdown dynamically so I could get number that user selected by index value
      const dropdown = document.getElementById("numOfPieces"); 
      var options = ["1", "2", "3", "4", "5"]; 
      
      for(var i = 0; i < options.length; i++) {
          var opt = options[i];
          var el = document.createElement("option");
          el.textContent = opt;
          el.value = opt;
          dropdown.appendChild(el);
      }

    //checks selected number
    let times = dropdown.options[dropdown.selectedIndex].value;
}

  $("#yes").click(function () {
    
    getOrderData();
}

Answer 1

function getOrderData() {
  alert('Hallo!!');
}

$("#yes").click(function () {
  let value = $('#numOfPieces').val();
  value = value && value>0 ? parseInt(value) : 1;
  for (let i = 0;  i < value; i++) {
    getOrderData();
  }
});

Answer 2

您可以使用 30 seconds of code 中的 times() 方法。这是该网站的代码，加上一个示例：

const times = (n, fn, context = undefined) => {
  let i = 0;
  while (fn.call(context, i) !== false && ++i < n) {}
};

times(5, i => console.log(`Called ${ i } times.`));
