如何对象数组值组合成1阵列? [英] How to combine object array values into 1 array?
问题描述
我有包含标记
阵列中的每个对象的数据对象,我想通过对象循环并抓住每一个对象标签,并结合最终结合值进入1阵列名为环路完成选
。目前,然而我无法解决这个问题,我已经试过推标签到一个数组,然后使用下划线_.union方法还尝试以串联每个环形阵列为1,但没有成功。谁能推荐一个解决方案?

JS
VAR的选择= [];VAR数据=(
{
角色:开发者,
标签:开发商,
标签:[使用Javascript,CSS,HTML]
},{
角色:制片人,
标签:生产者,
标签:项目管理,投球,结算]
}
]);
对于(VAR I = 0,LEN = data.length; I< LEN,我++){
selection.concat(数据[I] .tags添加);
}的console.log(选择);
您需要重新选
和CONCAT到寿了。所以使用:
为(VAR I = 0,LEN = data.length; I< LEN,我++){
选择= selection.concat(数据[I] .tags添加);
}
I have a data object with each object containing a tags
array, I would like to loop through the object and grab each of the object tags and combine eventually combine the values into 1 array called selections
on completion of the loop. At the moment however I'm unable to solve this, I have tried pushing the tags into an array then use the underscore _.union method and also tries concatenating each looped array into 1 but with no success. Can anyone recommend a solution?

JS
var selection = [];
var data = ([
{
role: "Developer",
tag: "developer",
tags: ["Javascript", "CSS", "HTML"]
}, {
role: "Producer",
tag: "producer",
tags: ["Project Management", "Pitching", "Billing"]
}
]);
for( var i = 0, len = data.length; i < len; i++ ) {
selection.concat(data[i].tags);
}
console.log(selection);
You need to reassign selection
, and concat to tho that. so use:
for( var i = 0, len = data.length; i < len; i++ ) {
selection = selection.concat(data[i].tags);
}
