示例 2 : 访问JSON数组
通过方括号[] 创建JSON 数组
<script>
var heros=
[
{"name":"盖伦","hp":616},
{"name":"提莫","hp":313},
{"name":"死歌","hp":432},
{"name":"火女","hp":389}
]
document.write("JSON数组大小"+heros.length);
</script>
<script>
var heros=
[
{"name":"盖伦","hp":616},
{"name":"提莫","hp":313},
{"name":"死歌","hp":432},
{"name":"火女","hp":389}
]
document.write("JSON数组大小"+heros.length);
</script>
访问JSON数组和访问普通数组一样，通过下标访问
<script>
var heros=
[
{"name":"盖伦","hp":616},
{"name":"提莫","hp":313},
{"name":"死哥","hp":432},
{"name":"火女","hp":389}
]
document.write( "第4个英雄是:" + heros[3].name);
</script>
<script>
var heros=
[
{"name":"盖伦","hp":616},
{"name":"提莫","hp":313},
{"name":"死哥","hp":432},
{"name":"火女","hp":389}
]
document.write( "第4个英雄是:" + heros[3].name);
</script>
