如何将任意小数位的点转换为逗号

Question

免费的 jqgrid 数据来自服务器的 json 字符串。它可以包含不同数量的小数位，例如

amount: "300.1", 
tax: "20.12", 
total: "320.123"

此数据应以逗号分隔的形式出现在 jqgrid 列中，如

300,1    20,12    320,123

为此创建了区域设置文件 grid.locale-et.js，内容为

formatter: {
    integer: {
        thousandsSeparator: " ",
        defaultValue: "0"
    },
    number: {
        decimalSeparator: ",",
        thousandsSeparator: " ",
        decimalPlaces: 2,
        defaultValue: "0,00"
    },

使用了 colmodel 中的

和 template: 'number' 选项。这显示了所有包含 2 位数字的列，如

300,10    20,12    320,12

如何解决此问题以便列显示正确的小数位数？

我试过colmodel

"template":"number",
"decimalPlaces":4

但它仍然显示两位小数。在不使用模板的情况下，显示正确的小数位数。

测试用例位于 http://jsfiddle.net/xssnr1gn/3/

它包含

 { id: "20",  invdate: "2007-10-02", name: "test2",  note: "note2",  amount: "300.1", tax: "20.12", closed: false, ship_via: "FE", total: "320.123" },

但是每列的输出都是小数点后两位。

更新

如果去掉decimalPlaces: 2,，jqgrid看起来像

问题：

小数点分隔符改为.
小数位数可变
无法理解的值7 146 2.8
对于某些数字 space 出现在小数点之前

来自服务器的数据包含固定的小数位数。如何显示与服务器数据中的小数位数完全相同的小数位数？

您需要应用格式化程序和格式选项

formatter: "number", formatoptions: {decimalSeparator:",", thousandsSeparator: " ", decimalPlaces: 4, defaultValue: '0.0000'}

完整代码：

$(function () {
    "use strict";
    var mydata = [
            { id: "10",  invdate: "2007-10-01", name: "test",   note: "note",   amount: "", tax: "", closed: true,  ship_via: "TN", total: "" },
            { id: "20",  invdate: "2007-10-02", name: "test2",  note: "note2",  amount: "300.1", tax: "20.12", closed: false, ship_via: "FE", total: "320.123" },
            { id: "30",  invdate: "2007-09-01", name: "test3",  note: "note3",  amount: "400.00", tax: "30.00", closed: false, ship_via: "FE", total: "430.00" },
