有规律:
遍历json对象
有如下 json对象:
var obj ={"name":"冯娟","password":"123456","department":"技术部","sex":"女","old":30}
遍历方法:
数组对象的遍历:
下面我们对照一下js和jquer的遍历方法:

看这样一段函数定义的代码就明白了function json_to_format_string(obj,deep){ var html = "" var blank_string = "" for (var i = 0i <deepi++) { blank_string += " " } for(var name in obj){ if (typeof(obj[name])=="object") { html += blank_string + name +": "+ "" html += json_to_format_string(obj[name],deep+1) }else{ html += blank_string + name +": "+ obj[name]+"
" } } return html}
用 for in 循环 遍历
var str = '[{"name":"宗2瓜","num":"1","price":"122"},{"name":"宗呱呱","num":"1","price":"100"}]'var xqo = eval('(' + str + ')')
for(var i in xqo){
alert(xqo[i].name)
}
