Assume
认为
var test = {
"movieCategories": [
"Animation",
"Romance",
"Science Fiction"
"Western"
]
}
then
然后
test.movieCategories[0] // Will be Animation

According to JSLintthis is invalid JSON. There is a "," missing:
根据JSLint，这是无效的 JSON。缺少一个“，”：
{ "movieCategories": [ "Animation", "Romance", "Science Fiction", "Western" ] }
For the rest see: Is it possible to parse JSON with javascript?

you can only use the eval like
你只能使用 eval 之类的
<html>
<div>
<script language="javascript">
var arr = '[{ "movieCategories": [ "Animation", "Romance", "Science Fiction" ,"Western" ] }]';
var b = eval(arr)[0];
alert(b.movieCategories);
</script>
</div>
</html>
