console.log(json)//{"2017-12-07":["現(xiàn)在天氣冷了","什么時(shí)候變熱"],"2017-12-08":["什么時(shí)候過年","春節(jié)放假怎么安排"]}
我只是寫一個(gè)大概
就是個(gè)雙層循環(huán)
var str = "";
for(var key in json){
str+=`<h1>${key}</h1>`;
str+=`<div>`;
for(var i=0;i<json[key].length;i++){
str+=`<p>${json[key][i]}</p>`
}
str+=`</div>`;
}
console.log(str)
/*
<h1>2017-12-07</h1>
<div>
<p>現(xiàn)在天氣冷了</p>
<p>什么時(shí)候變熱</p>
</div>
<h1>2017-12-08</h1>
<div>
<p>什么時(shí)候過年</p>
<p>春節(jié)放假怎么安排</p>
</div>
