Php 从json返回多个值
目前,我正在使用一个脚本,该脚本以msg[0].box msg[1].box等格式从json返回一个值。如果用户输入(比如)2项,这是可以的。但是,如果用户输入的内容不止这些呢。我的一位朋友建议我查看jquery的每个函数以重新运行多个值,但鉴于我对jquery还相当陌生,如果有人能帮助我使用代码实现这一点,我将不胜感激 我也很困惑,为什么在返回值时firebug中没有json选项卡,只有resosse和html。这正常吗?请注意,输入值时使用,作为分隔符 php代码Php 从json返回多个值,php,javascript,jquery,Php,Javascript,Jquery,目前,我正在使用一个脚本,该脚本以msg[0].box msg[1].box等格式从json返回一个值。如果用户输入(比如)2项,这是可以的。但是,如果用户输入的内容不止这些呢。我的一位朋友建议我查看jquery的每个函数以重新运行多个值,但鉴于我对jquery还相当陌生,如果有人能帮助我使用代码实现这一点,我将不胜感激 我也很困惑,为什么在返回值时firebug中没有json选项卡,只有resosse和html。这正常吗?请注意,输入值时使用,作为分隔符 php代码 $dept = m

关于如何使用$。每个功能
var html = "You have entered box(es): <b>"
$.each(msg, function(index, element) {
if(index > 0)
html += " ";
html += element.box;
});
html += "</b><br /> You may now close this window."
var html=“您已输入框:”
$.each(msg,函数(索引,元素){
如果(索引>0)
html+=“”;
html+=element.box;
});
html+=“
您现在可以关闭此窗口。”

您的结果将根据您的输出作为javascript中的数组进行计算。请看参考资料:
为了演示的目的,我刚刚对您的方法的输出进行了两个以上的虚拟测试。因此,php脚本的结果可能如下所示:
[{
"dept": "dept",
"company": "conmpany",
"address": "address",
"service": "service",
"box": "box1",
"destroydate": "destroydate",
"authorised": "authorised",
"submit": "submit"
}, {
"dept": "dept",
"company": "conmpany",
"address": "address",
"service": "service",
"box": "box2",
"destroydate": "destroydate",
"authorised": "authorised",
"submit": "submit"
}, {
"dept": "dept",
"company": "conmpany",
"address": "address",
"service": "service",
"box": "box3",
"destroydate": "destroydate",
"authorised": "authorised",
"submit": "submit"
}]
$.post('/sample/admin/requests/boxes/boxesadd.php', data, function(msg) {
var messageOutput = '';
for (var i = 0; i<msg.length; i++){
messageOutput += msg[i].box+' ';
}
$("#BA_addbox").html("You have entered box(es): " + "<b>" + messageOutput + "</b><br /> You may now close this window.");
//console.log(msg[0].box);
$("#BA_boxform").get(0).reset();
}, 'json');
在javascript方面,这是作为对象数组处理的。由于是一个标准数组,
循环的足以检索值,因此您的方法可能如下所示:

"company": "conmpany",
"address": "address",
"service": "service",

对于(var i=0;没有JSON选项卡,原因响应与非JSON响应类型标题一起提供(例如,text/html
