How to traverse json array using key value in JS
This time I will show you how JS uses key values to traverse json arrays. What are the precautions for JS to use key values to traverse json arrays. Here is a practical case, let’s take a look.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>js键值对遍历json数组</title>
</head>
<body>
<script type="text/javascript">
var data = [];
var data = [];
data['上海'] = [{
city:'闵行',
value:'minhang'
},{
city:'浦东',
value:'pudong'
}];
data['四川'] = [{
city:'温江',
value:'wenjiang'
},{
city:'成都',
value:'chengdu'
}];
// 遍历数组
for(var province in data){
for(var i=0;i<data[province].length;i++){
console.log(province + ' - ' + data[province][i].city + ' - ' + data[province][i].value);
}
}
</script>
</body>
</html>The running results are as follows:
