Question

我有一个使用jQuery的脚本来计算货币。它可以正常工作，但是当我写一个大于999,99的值时，当我使用掩码并将结果转换为money格式时，它会返回错误的值。我该如何解决？

已更新

$(document).ready(function() { 
    $('.money').mask("#.##0,00", {reverse: true});
});

accounting.settings = {
  currency: {
    symbol : "",   // default currency symbol is '$'
    format: "%s%v", // controls output: %s = symbol, %v = value/number (can be object: see below)
    decimal : ",",  // decimal point separator
    thousand: ".",  // thousands separator
    precision : 2   // decimal places
  },
  number: {
    precision : 0,  // default precision on numbers is 0
    thousand: ".",
    decimal : ","
  }
}


function calc(){
  var plano = parseFloat($("#regimento").val().replace(/,/g, '.'));
  var gasto = parseFloat($("#gasto_contabilidade").val().replace(/\./g, ',').replace(/,/g, '.'));
  var meses = parseInt( $("#meses").val());

  var resultado_gasto = parseFloat(gasto * meses);
  var resultado_plano = parseFloat(plano * meses);

  var result = resultado_gasto - resultado_plano;
  result = accounting.formatMoney(result);
  console.log(result)
}

Answer 1

您需要记住，从.val()获取select时，它以字符串形式出现，您应该在进行一些计算之前对其进行解析。

此外，我不知道您为什么使用input type="tel"作为数字，使用type="number"

下面的代码正在工作，并且没有显示NaN ...我只是不知道计算结果是否正是您要寻找的，

OBS ：您不能像#gasto_contabilidade那样使用1.234,55中的值，它必须是1234.55或1234,55（这仅仅是因为您将替换,。

function calc(){
  var plano = parseFloat($("#regimento").val().replace(/,/g, '.'));
  var gasto = parseFloat($("#gasto_contabilidade").val().replace(/\./g, ',').replace(/,/g, '.'));
  var meses = parseInt( $("#meses").val());

  var resultado_gasto = parseFloat(gasto * meses);
  var resultado_plano = parseFloat(plano * meses);

  var result = resultado_gasto - resultado_plano;
  console.log(result)
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="" id="regimento" class="select">
  <option value="19,90">MEI</option>
  <option value="85,90">SIMPLES SERVIÇO</option>
  <option value="199,90">SIMPLES COMÉRCIO E INDÚSTRIA</option>
</select>

<input id="gasto_contabilidade" type="number" class="valor" value="1000">

<select id="meses" class="select">
  <option value="12">12</option>
  <option value="13">13</option>
</select>
<input type="button" onclick="calc()" value="Calculate">

Answer 2

您没有使用meses变量
在将.replace与字符串一起使用时，它仅替换单个匹配项。与正则表达式一起使用时，它会替换所有出现的内容
```
 gasto.replace(/,/gi,'.').replace(/ /gi,'')
```

那样字符串可以正确替换

太好了，谢谢，但是如果我用accounting.js格式化值，效果会不太好，请看：

$(document).ready(function() { 
    $('.money').mask("#.##0,00", {reverse: true});
});

accounting.settings = {
  currency: {
    symbol : "",   // default currency symbol is '$'
    format: "%s%v", // controls output: %s = symbol, %v = value/number (can be object: see below)
    decimal : ",",  // decimal point separator
    thousand: ".",  // thousands separator
    precision : 2   // decimal places
  },
  number: {
    precision : 0,  // default precision on numbers is 0
    thousand: ".",
    decimal : ","
  }
}


function calc(){
  var plano = parseFloat($("#regimento").val().replace(/,/g, '.'));
  var gasto = parseFloat($("#gasto_contabilidade").val().replace(/\./g, ',').replace(/,/g, '.'));
  var meses = parseInt( $("#meses").val());

  var resultado_gasto = parseFloat(gasto * meses);
  var resultado_plano = parseFloat(plano * meses);

  var result = resultado_gasto - resultado_plano;
  result = accounting.formatMoney(result);
  console.log(result)
}

FIX：

我解决了在计算点之前删除点的问题

var gasto = $("#gasto_contabilidade").val().replace(".", '');

谢谢大家的帮助！

$(document).ready(function() { 
    $('.money').mask("#.##0,00", {reverse: true});
});

accounting.settings = {
  currency: {
    symbol : "",   // default currency symbol is '$'
    format: "%s%v", // controls output: %s = symbol, %v = value/number (can be object: see below)
    decimal : ",",  // decimal point separator
    thousand: ".",  // thousands separator
    precision : 2   // decimal places
  },
  number: {
    precision : 0,  // default precision on numbers is 0
    thousand: ".",
    decimal : ","
  }
}


function calc(){
  var gasto = $("#gasto_contabilidade").val().replace(".", ''); // FIX
  plano = parseFloat($("#regimento").val().replace(/,/g, '.'));
  gasto = parseFloat(gasto.replace(/\./g, ',').replace(/,/g, '.'));
  var meses = parseInt( $("#meses").val());

  var resultado_gasto = parseFloat(gasto * meses);
  var resultado_plano = parseFloat(plano * meses);

  var result = resultado_gasto - resultado_plano;
  result = accounting.formatMoney(result);
  console.log(result)
