<script>
var obj = "([{name:"think",gender:"male"},{name:"lee",gender:"female"}])";
var ss = eval(obj);
alert(ss.length);
alert(ss[0].name+","+ss[1].name);

看一款 php数组生成json的类.

class json {
   
    var $jsonarr = array();
    var $json = "";
   
    /*递归生成json*/
    function jsonencode($jsonarr) {
        $this->json = empty($this->json) ? "{" : $this->json;
        foreach($jsonarr as $key => $var) {
            if(is_array($var)) {
                $this->json .= """.$this->jsonkey($key)."":{";
                $this->json .= $this->jsonstr($var).",";
            } else {
                $this->json .= """.$this->jsonkey($key)."":"".$this->jsonvar($var)."",";
            }
        }
        $this->json = substr($this->json, 0, -1)."}";
     }
   
    /*过滤值中特殊字符*/
    function jsonvar($var) {
        $var = str_replace(array("""), array("""), $var);
        return $var;
    }
   
    /*过滤键值中特殊字符*/
    function jsonkey($key) {
        $key = str_replace(array(""", ":", """), array("", "", ""), $key);
        return $key;
    }
}

//调用

$obj = new json;
$obj->jsonencode($arr);
echo $obj->json;

?>
