使用JS传递数组型数据回服务器

//为数组添加一个方法，判断某个值是否存在于数组中
Array.prototype.in_array = function (e) {
for (i = 0; i < this.length && this[i] != e; i++);
return !(i == this.length);
}

var array = new Array();

//数组中的Item
var arr = {
//"RFQID": $("#ID").val(),
"RFQID": $(this).attr("rfqid"),
"SiteCode": $(this).attr("site"),
"ProcessID": $(this).attr("processid"),
"ForecastLoading": $(this).val(),
"SimulateNumber": 2,
"MainRFQID": $("#ID").val()
}

array .push(arr); //将Item塞入数组
