javascript - 迭代对象文字并替换字符串

Question

有人可以帮助我了解如何使用 jQuery $.each 循环对象文字并替换每个项目中匹配的字符串的语法吗？

如果我有:

var foo = {
    item1: "Mary had a little lamb",
    item2: "Whose fleece was white as snow",
    item3: "Johnny ha a little lamb",
    item4: "What's the deal with lambs?"
}

我想用 lion 替换单词 lamb，我应该在 $.each 函数中的哪个位置替换该项目？

我已经尝试过:

$.each(foo, function(key, value){
     return value.replace(/lamb/, "lion");
}

但它并没有取代这些元素？

Answer 1

使用字符串replace替换文本并更新对象值的方法

var foo = {
  item1: "Mary had a little lamb",
  item2: "Whose fleece was white as snow",
  item3: "Johnny has a little lamb",
  item4: "What's the deal with lambs?"
}
$.each(foo, function(i) {
  foo[i] = foo[i].replace('lamb', 'lion')
});
console.log(foo)
