如何遍历JavaScript对象中的所有成员,包括对象值。
例如,如何循环浏览(分别访问“ your_name”和“ your_message”)?
var validation_messages = { "key_1": { "your_name": "jimmy", "your_msg": "hello world" }, "key_2": { "your_name": "billy", "your_msg": "foo equals bar" } }
for (var key in validation_messages) { // skip loop if the property is from prototype if (!validation_messages.hasOwnProperty(key)) continue; var obj = validation_messages[key]; for (var prop in obj) { // skip loop if the property is from prototype if (!obj.hasOwnProperty(prop)) continue; // your code alert(prop + " = " + obj[prop]); } }
