Javascript将数组转换为键值对格式的对象

Question

How do I convert simple array or may be a comma separated value to object something like the one mentioned below?

var arry=['a','b','c','d'];
var obj=[{
            'label':'a',
            'id':'',
            'icon':''
        },
        {
            'label':'b',
            'id':'',
            'icon':''
        }, {
            'label':'c',
            'id':'',
            'icon':''
        },
        {
            'label':'d',
            'id':'',
            'icon':''
        }];

Answer 1

Use this:

var arry=['a','b','c','d'];
var obj=[];

for (var i in arry){
    obj.push({
        'label':arry[i],
        'id':'',
        'icon':''
    });
}
