[英]How do I iterate through this object using JavaScript?
Let's say I have the follow: 假设我有以下几点:
var test_data = {
'numGroup1': [[(1, 2, 3, 4, 5), (5, 6, 7, 8, 9)]],
'numGroup2': [[(10, 11, 12, 13, 14), (15, 16, 17, 18, 19)]],
};
How would I go about iterating through it using JavaScript? 我将如何使用JavaScript进行迭代?
var test_data = {
'numGroup1': [[1, 2, 3, 4, 5], [5, 6, 7, 8, 9]],
'numGroup2': [[10, 11, 12, 13, 14], [15, 16, 17, 18, 19]],
};
for(var key in test_data){
group = test_data[key];
for(var num in group){
console.log(group[num]);
}
}
@Ian is right... using () will not do anything but enter the last digit of each group. @Ian是正确的...使用()不会做任何事情,而是输入每个组的最后一位。 You should use a multidimensional array
您应该使用多维数组
'numGroup1': [[1, 2, 3, 4, 5], [5, 6, 7, 8, 9]],
'numGroup2': [[10, 11, 12, 13, 14], [15, 16, 17, 18, 19]],
You can use underscorejs to iterate over it 您可以使用underscorejs对其进行迭代
var test_data = {
'numGroup1': [[1, 2, 3, 4, 5], [5, 6, 7, 8, 9]],
'numGroup2': [[10, 11, 12, 13, 14], [15, 16, 17, 18, 19]],
};
_.chain(test_data).map(function(value, key) {
return value;
}).flatten().each(alert);
