Question

有人可以帮助我使用jQuery $.each循环访问对象文字的语法，并替换每个项目中匹配的字符串吗？

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lamb替换单词lion，在$ .each函数中我替换项目吗？

我试过了：

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

但它不能替换这些物品吗？

使用字符串replace方法替换文字＆amp;更新对象的值

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)
