思路
第一种方法：通过把json中需要的值取出来，重新生成json对象，这种方法比较笨
第二种方法：通过delete 删除属性，这种方法比较常用，在第三方js库中经常能看到，推荐
举例
<script>var s = [{"name":"tank","total":"100"},{"name":"zhang","total":"23"},{"name":"hao","total":"325"}]
for(var k=0k<s.lengthk++){
delete s[k]["name"]
}
</script>
var str=[{"id":"111","name":"张","age":"24","text":15},{"id":"222","name":"三","age":"25","text":15},{"id":"333","name":"张三","age":"26","text":15}]var s=[]
var l={}
for (var i=0i<str.lengthi++)
{ for(var a in str[i])
{
if(a!="text")
{
l[a]=str[i][a]
}
}
s[i]=l
}
通过复制数组来实现，当为text时则不复制，最后可实现删除text元素功能
