<p>It's possible. You can use the <code>.map</code> function.</p>

<pre><code>var tagNames = obj.Tags.map(function(x){
    return x.TagName;
});
</code></pre>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var obj = {

    [{"TagId":"T1","TagName":"test2","TagType":1},

var tagNames = obj.Tags.map(function(x){

console.log(tagNames)</code></pre>

blocks|key|786759|text|我想我可能明白你的问题是什么了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|786760|您希望您的标记仅是数组的TagName吗？|offset|length|style|BOLD|786761|下面是示例代码：|786762|​|786763|var+Obj+=+{

<p>I think I probably get what your question is.</p>

<p>Would you like your Tags to be only <strong>array of TagName</strong>?</p>

<p>Here's example code:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var Obj = {

 "Type":6,"Fav":false,
 "Shield":false,
 "Tags":"[{\"TagId\":\"T1\",\"TagName\":\"test2\",\"TagType\":1},  {\"TagId\":\"T2\",\"TagName\":\"test1\",\"TagType\":1}]"
}

// Get Tags data to array object

var Tags = JSON.parse(Obj.Tags);

// Get simple array of TagNames

var TagNames = Tags.map(x=&gt;x.TagName);
console.log(TagNames);

// Get array of objects with only TagName key value pair

var TagNamesFormat2 = Tags.map(function(x){
  return {"TagName" : x.TagName}
});

console.log(TagNamesFormat2);</code></pre>

<p>I have the following javascript </p>

<pre><code>{

 "Type":6,"Fav":false,

 "Tags":"

    {\"TagId\":\"T2\",\"TagName\":\"test1\",\"TagType\":1}]"
}
</code></pre>

<p>What I am trying to do is, to use <code>javascript</code> to get the <code>TagName</code> from <code>Tags</code> section </p>

<p>When i use <code>JSON.parse(Obj.Tags);</code> I get everything under <code>Tags</code> section where i only want <code>TagName</code></p>

<p>Is it possible?</p>
