Javascript 使用多种形式舍入小数点后的两个空格

javascript php html

Javascript 使用多种形式舍入小数点后的两个空格,javascript,php,html,Javascript,Php,Html,我试图在文本框“76.50”中得到这样的答案，而不是“76.5”，仅供参考“distanceTotal”、“rateTotal”和“dimensionsTotal”分别属于不同的单独形式（共三种形式），并已成功转换为小数点后的两个空格 “hiddenTotal”和“ultimateTotal”来自（第四种形式），并且（未）成功地转换为小数点后的两个空格的四舍五入，这正是我们在这里需要的 function calculate() { "use strict"; setValues(); var

我试图在文本框“76.50”中得到这样的答案，而不是“76.5”，仅供参考“distanceTotal”、“rateTotal”和“dimensionsTotal”分别属于不同的单独形式（共三种形式），并已成功转换为小数点后的两个空格

“hiddenTotal”和“ultimateTotal”来自（第四种形式），并且（未）成功地转换为小数点后的两个空格的四舍五入，这正是我们在这里需要的

function calculate() {
"use strict"; setValues();

var a = document.getElementById('distanceTotal').value;
var b = document.getElementById('rateTotal').value;
var result = document.getElementById('hiddenTotal');
var myResult = (a * 1.00 * b * 1.00);
result.value = myResult;


var d = document.getElementById('dimensionsTotal').value;
var e = document.getElementById('hiddenTotal').value;
var result2 = document.getElementById('ultimateTotal'); 
var myResult2 = (d * 1.00 + e * 1.00);
result2.value = myResult2;

地址来自
从输入
中获取值
，将其解析为浮点
，最后使用toFixed
将解析值四舍五入并格式化为两位小数，如下所示：


函数格式（）{
让输入=document.querySelector（“输入”）；
input.value=parseFloat（input.value）.toFixed（2）；//设置两位小数
}
格式化
Tryvalue.toFiexd（2）
。这似乎不起作用也许我没有把它放在正确的位置我用来得到答案的值已经转换成小数点后的两个空格，所以可能是因为我试图将字符串中的值计算成另一个字符串？
