提问by ashish
I'm looking to make an object containing latitudes and longitudes of various places such as [["Second Event",19.0554748,72.8497017],["Demo Event",19.2097381,72.8737017]].
我希望制作一个包含各个地方的纬度和经度的对象，例如[["Second Event",19.0554748,72.8497017],["Demo Event",19.2097381,72.8737017]].
I'm successful of making this in phpby using json_encode()function. How do I retrieve it in the callback function. I've tried the following:
我php通过使用json_encode()函数成功地做到了这一点。如何在回调函数中检索它。我尝试了以下方法：
$.post('maps1.php',{},function(data){
alert(data);
markers=JSON.stringify(data);
},"json");
alert(markers);
However this doesn't seems to work. What should I do?
然而，这似乎不起作用。我该怎么办？

You have the scope for the variable markers inside the post method, try doing it like this:
您在 post 方法中有变量标记的范围，请尝试这样做：
var markers = '';
$.post('maps1.php', {}, function (data) {
alert(data);
markers = JSON.stringify(data);
}, "json");
alert(markers)

$.ajaxshould do this way:
$.ajax应该这样做：
var marker;
$.ajax({
url:'maps1.php',
data:{},
type:'POST',
dataType:'json',
success:function(data){
alert(data);
marker = JSON.stringify(data);
},
complete:{
alert(marker);
}
});
and $.POSTshould be like this:
而$.POST应该是这样的：
$.post('maps1.php',{},function(data){
alert(data);
},"json").done(function(data){
markers=JSON.stringify(data);
alert(markers);
});
