JavaScript iterate key & value from json?
提问by Prashant Vhasure
I am trying to iterate the following json:
我正在尝试迭代以下 json：
{
"VERSION" : "2006-10-27.a",
"JOBNAME" : "EXEC_",
"JOBHOST" : "Test",
"LSFQUEUE" : "45",
"LSFLIMIT" : "2006-10-27",
"NEWUSER" : "3",
"NEWGROUP" : "2",
"NEWMODUS" : "640"
}
Here key is dynamic. I want both key = ? and value = ?
这里的关键是动态的。我想要两个键 = ？和价值 = ?

Use Object.keys()to get keys array and use forEach()to iterate over them.
使用Object.keys()获得的密钥阵列和使用forEach()对他们进行迭代。
var data = {
"VERSION": "2006-10-27.a",
"JOBNAME": "EXEC_",
"JOBHOST": "Test",
"LSFQUEUE": "45",
"LSFLIMIT": "2006-10-27",
"NEWUSER": "3",
"NEWGROUP": "2",
"NEWMODUS": "640"
};
Object.keys(data).forEach(function(key) {
console.table('Key : ' + key + ', Value : ' + data[key])
})回答by Jamiec
You can use Object.keysfor that.
你可以用Object.keys它。
var keys = Object.keys(yourObject);
for(var i=0; i<keys.length; i++){
var key = keys[i];
console.log(key, yourObject[key]);
}
