Join JSON Object member string values together
提问by 0pt1m1z3
"category": [{
"id": 28,
"name": "Dogs"
},
{
"id": 14,
"name": "Cats"
},
{
"id": 878,
"name": "Sheep"
}],
I have the above JSON parsed (using .ajax and jsonp as callback) and I would like to join all the values of "name" into a string. i.e. "Dogs, Cats, Sheep". How can I do this? I have tried simple join on "category" and name, i.e.
我解析了上面的 JSON（使用 .ajax 和 jsonp 作为回调），我想将“name”的所有值加入一个字符串。即“狗，猫，羊”。我怎样才能做到这一点？我已经尝试过对“类别”和名称的简单连接，即
var cats = categories.join(", ");
OR
或者
var cats = categories.name.join(", ");
But since we are looking at it's members and their string values, it doesn't work.
但是由于我们正在查看它的成员及其字符串值，因此它不起作用。

This looks like a job for $.map!
这看起来像是一份工作$.map！
var data = {
"category": [{
"id": 28,
"name": "Dogs"
},
{
"id": 14,
"name": "Cats"
},
{
"id": 878,
"name": "Sheep"
}]
}
var cats = $.map(data.category, function(v){
return v.name;
}).join(', ');

var text = "";
for(var i=0; category.length; i++)
{
text += category[i].name;
if(i!=category.length-1)
text += ", ";
}
