各位JS高手，想用JS打印这个JSON字符串啊

Question

[{"1":"高洪岩1","2":"高洪岩2","3":"高洪岩3","4":"高洪岩4","5":"高洪岩5"}]如何循环遍历出来？

Answer 1

是str ='[{"1":"高洪岩1","2":"高洪岩2","3":"高洪岩3","4":"高洪岩4","5":"高洪岩5"}] '还是arr = [{"1":"高洪岩1","2":"高洪岩2","3":"高洪岩3","4":"高洪岩4","5":"高洪岩5"}] 

Answer 2

[{"1":"高洪岩1","2":"高洪岩2","3":"高洪岩3","4":"高洪岩4","5":"高洪岩5"}]
是JSON对象，不是字符串 

Answer 3

<script>
str ='[{"1":"高洪岩1","2":"高洪岩2","3":"高洪岩3","4":"高洪岩4","5":"高洪岩5"}] ' 
var arr = eval("("+str+")");
for(var i in arr[0])
alert("属性为："+i+"=====>"+"值为："+arr[0][i])
</script>
