Question

我需要在哪里设置.toFixed（2）方法才能为我的范围滑块输出设置固定格式？ 1.9 - ＆gt; 1.90 2 - ＆gt; 2.00

此外，是否可以有一个输入字段，用户将其价格（格式（GER）：0,00€）并将其转换为0.00€，并根据用户输入更改slidevalue？

非常感谢！

function outputUpdate(vol) {
	document.querySelector('#volume').value = vol;
}

function outputUpdate2(vol2) {
	document.querySelector('#volume2').value = vol2;
}


  function TKPJ(){
  		var Field1 = document.getElementById('Field1').value;
  		var Field2 = document.getElementById('Field2').value;
  		var Field3 = document.getElementById('Field3').value;
  		var Format = document.getElementById('Format').value;
  		var Slider1 = document.getElementById('Slider1').value;
  		var Slider2 = document.getElementById('Slider2').value;
			var vol = document.getElementById('volume').value;
			var vol2 = document.getElementById('volume2').value;
  		var Total = ((Field1*Field2*Field3*Format*vol*vol2)/100).toFixed(2);

  		Total = Total.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
  		document.getElementById('Total').innerHTML = "Cost per year = "+ Total +" €";





  }

 <p>Field1</p>
        			          <input type="number" name="Field1" id="Field1" onkeyup="TKPJ()">

        <output for="Preisliter" id="volume"> 1.50 </output>
                        <br>

                          <h3 id="Total">Cost per year = 0,00€</h3>

Answer 1

在致电.toFixed(2)之前，您必须解析编号为字符串的数字。解析后，您有数字对象，可以正确调用.toFixed()方法

function outputUpdate2(vol2) {
    document.querySelector('#volume2').value = parseFloat(vol2).toFixed(2);
}

价格格式和用户输入值以更改滑块
