如何正确收集数字并将其放入另一张表

使用此方法进行实验但未正确收集

   <script>

   // A
   $(function() {

var nums=[];
var tot=0;

 $(' .vis ').each(function(i){
var numTxt = $('.vis:eq('+i+') tr > td:eq(1)').text().match(/\d+/g)[0];

var num = (parseInt(numTxt ,10));
   nums.push(numTxt);
   tot+=num

});

  $("#ABS #A").html(tot); 


});

// B
   $(function() {

var nums=[];
var tot=0;

 $(' .vis ').each(function(i){
var numTxt = $('.vis:eq('+i+') tr > td:eq(1)').text().match(/\d+/g)[1];

var num = (parseInt(numTxt ,10));
   nums.push(numTxt);
   tot+=num

});

  $("#ABS #B").html(tot); 

});

//C
   $(function() {

var nums=[];
var tot=0;

 $(' .vis ').each(function(i){
var numTxt = $('.vis:eq('+i+') tr > td:eq(1)').text().match(/\d+/g)[2];

var num = (parseInt(numTxt ,10));
   nums.push(numTxt);
   tot+=num

});

  $("#ABS #C").html(tot); 

});

   </script>

但我想要

88.334 + 822 + 88.332 + 88.332 + 555 = 1531.666

然后将总数放在这里

$("#ABS #A").html(tot);

和..
30.665 + 303 + 30.665 + 30.665 + 220 = 584.33

$("#ABS #B").html(tot);

和..

20.453 + 20 + 20.453 + 20.453 + 110 = 191.359

$("#ABS #C").html(tot);

我只想要这个（1531.666）

和（584.33）

和（191.359）

我想要这个，怎么样？!!

Answer 1

您只获取数字并解析为整数，您需要获取句点和后面的数字，删除句点周围的空格，并将其解析为浮点数：

var numTxt = $('.vis:eq('+i+') tr > td:eq(1)').text().replace(/ \. /g, '.').match(/[\d.]+/g)[0];

var num = parseFloat(numTxt);

我怎样才能正确收集数字（jquery）
