php - 如何通过 GET 将 javascript 数组传递给 php？

Question

我必须通过 http GET 将数组从 javascript 传递到 php 脚本amount。name

var amount=new Array();   
amount = document.form_perk.elements["amount[]"];  
var name = document.form_perk.elements["name[]"];
http.open('get', 'perks.php?+obj2url("amount", amount)&obj2url("name", name)');   
http.onreadystatechange = insertReply;  
http.send(null);

这是怎么做到的？

Answer 1

编辑：看来问题是这样的：

http.open('get', 'perks.php?+obj2url("amount", amount)&obj2url("name", name)'); 

应该：

http.open('get', 'perks.php?' + obj2url("amount", amount) + '&' + obj2url("name", name)');

使用此功能（从此处修改）：

function EncodeQueryData(arr_data, str_prepend) {
   str_prepend = str_prepend || "";
   var ret = [];
   for (var d in arr_data)
       ret.push(encodeURIComponent(str_prepend + d) + "=" + encodeURIComponent(arr_data[d]));
   return ret.join("&");
}

var base_url = "perks.php";
var query_string = EncodeQueryData(amount, "amount") + '&' + EncodeQueryData(name, "name");
window.location = base_url + '?' + query_string;

这应该给你例如这样的东西：

perks.php?amount0=10&amount1=27&name0=john&name1=sally.
