javascript ajax 传递二维数组

function cart_edit(){
var rec_id_arr=new Array();
var text=document.getElementById("formCart").getElementsByTagName("input");
var total_price=0;
for(var i=0;i<text.length;i++){
if(text[i].type=="text"){
rec_id_arr[text[i].id.replace("goods_number_","")]=new Array();

rec_id_arr[text[i].id.replace("goods_number_","")]["number"]=document.getElementById("goods_number_"+text[i].id.replace("goods_number_","")).value;
rec_id_arr[text[i].id.replace("goods_number_","")]["price"]=document.getElementById("price_val_"+text[i].id.replace("goods_number_","")).value;
}
}
alert(rec_id_arr.toString());
Ajax.call('../ajax/cart.php', 'goods=' + rec_id_arr, hrefgo, 'POST', 'JSON');
}
rec_id_arr. 如何写才能传递给php

Answer 1

function encodeStr (array) {
var str = '';
for (var i = 0, a; a = array[i]; i ++) {
a = a.join(',');
}
return array.join(',');

}

执行完函数encodeStr(rec_id_arr);后得到就是一个将二维数组解析好了的字符串。

将字符串当成参数传过去，PHP那边接到字符串再decode一下就可以得到一个Array了
