Question

我有一个对象，其中一对具有逗号的值。我想删除对象中所有这些值的逗号，并返回修改后的对象。对象如下 -

var obj = [
            {
            id: 1,
            Product1: "Table",
            Phone1: "9878987",
            Price:"21,000"},
        {
            id: 2,
            Product1: "Chair",
            Phone1: "9092345",
            Price:"23,000"},
        {
            id: 3,
            Product1: "Cupboard",
            Phone1: "9092345",
            Price:"90,000"}    
        ];

alert(JSON.stringify(obj));

我想删除价格值中的逗号（例如23,000 ==＆gt; 23000）。怎么办呢？

Answer 1

您可以使用Array.prototype.forEach()来迭代所有商品并修改item.Price：

var obj = [{id: 1,Product1: "Table",Phone1: "9878987",Price:"21,000"},{id: 2,Product1: "Chair",Phone1: "9092345",Price:"23,000"},{id: 3,Product1: "Cupboard",Phone1: "9092345",Price:"90,000"}];

obj.forEach(function(item) {
  item.Price = item.Price.replace(/,/, '');
});      

console.log(obj);

试试这个会起作用：

var obj = [
            {
            id: 1,
            Product1: "Table",
            Phone1: "9878987",
            Price:"21,000"},
        {
            id: 2,
            Product1: "Chair",
            Phone1: "9092345",
            Price:"23,000"},
        {
            id: 3,
            Product1: "Cupboard",
            Phone1: "9092345",
            Price:"90,000"}    
        ];

for (var i in obj) {
  var Price = obj[i].Price.replace(',','');
  obj[i].Price = Price;
}        

  console.log(obj);

您可以使用RegEx进行替换。这适用于字符串中的任意数量的逗号。

＆＃13;

var obj = [{
  id: 1,
  Product1: "Table",
  Phone1: "9878987",
  Price: "1,21,000"
}, {
  id: 2,
  Product1: "Chair",
  Phone1: "9092345",
  Price: "23,000"
}, {
  id: 3,
  Product1: "Cupboard",
  Phone1: "9092345",
  Price: "90,000"
}];

var modifiedArray = obj.map(function(currentObj) {
  var replaceRegex = new RegExp(",", "g");
  currentObj.Price = currentObj.Price.replace(replaceRegex, "");
  return currentObj;
});
document.querySelector("#result").innerHTML =
  JSON.stringify(modifiedArray);

＆＃13;

<div id="result">
</div>

你可以使用正则表达式而不使用循环。

var obj= ... //your array
obj= JSON.stringify(obj);
obj= obj.replace(/(?=,(?!"))(,(?!{))/g,"");
obj= JSON.parse(obj) //you get you object without , in between your values
