1、问题背景
有一个json字符串,需要将其转换成json对象;若str是一个json字符串,将str转换成json对象
(1)eval(“(“+str+”)”)
(2)JSON.parse(str)
2、实现源码
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>JSON字符串转换成JSON对象</title> <script type="text/javascript"> function strToObject() { var str = '{"name":"zhangsan","sex":"男","age":"29"}'; var obj = eval("("+str+")"); var obj1 = JSON.parse(str); alert(typeof(obj1)); } </script> </head> <body> <div id="body_div" style="vertical-align:middle; text-align:center;"> <input type="button" id="btn" value="转换" onclick="strToObject()"/> </div> </body> </html>
