javascript - 将数组对象连接成一个字符串

Question

我有一个这样的数组

var Data = [{
"words": [
    "dolor",
    "sit",
    "amet",
    "consectetur"
],
    "description": "Lorem Ipsum."
}, {
"words": [
    "adipisicing",
    "elit",
    "sed",
    "do"
],
    "description": "Lorem Ipsum."
}];

如何将所有单词连接成一个字符串，用单竖线符号“|”分隔？所需的输出应如下所示:(dolor|sit|amet|consectetur|adipisicing|elit|sed|do)

Answer 1

这样做

Data.map(function(obj){ return obj.words.join("|") }).join("|");

返回 "dolor|sit|amet|consectetur|adipisicing|elit|sed|do"
