数组显示未定义的jQuery发布功能 [英] array showing undefined outside the jquery post funtion
问题描述
你好朋友
我正在尝试使用$ .post()从数据库中获取数据，它会向我返回数据
我再次在拳头中使用$ .post()
我试图将数据推入第二个$ .post()
中的数组中
数组长度显示在第二个$ .post()内部，但在它外部显示长度0
以下是我的代码
Hello Friends
I am trying to get the data from database using $.post() it returns me data
I am again using $.post() inside the fist one
and i am trying to push that data in array inside second $.post()
array length is showing inside second $.post() but outside it it is showing length 0
Below is my code
$.post('/Common/getInfo/', null, function (data) {
var desc = [];
var ultlng =[];
var count = 0;
for (var i = 0; i < data.length; i++) {
desc.push(data[i].Description);
$.post('/Common/getLatlngInfo/', { id: data[i].ID }, function (data1) {
for (var j = 0; j < data1.length; j++) {
if (j == 0) {
ultlng.push(new google.maps.LatLng(data1[j].Latitude, data1[j].Longitude));
}
if (data1.length > 1) {
if (j == data1.length - 1) {
var flightPlanCoordinates = [
new google.maps.LatLng(data1[0].Latitude, data1[0].Longitude),
new google.maps.LatLng(data1[1].Latitude, data1[1].Longitude),
new google.maps.LatLng(data1[2].Latitude, data1[2].Longitude),
new google.maps.LatLng(data1[3].Latitude, data1[3].Longitude),
new google.maps.LatLng(data1[4].Latitude, data1[4].Longitude)
];
var flightPath = new google.maps.Polyline({
path: flightPlanCoordinates,
geodesic: true,
strokeColor: '#007ACC',
strokeOpacity: 1.0,
strokeWeight: 3
});
flightPath.setMap(map);
}
}
else {
ultlng.push(new google.maps.LatLng(data1[j].Latitude, data1[j].Longitude));
}
}
});
}
for (var i = 0; i < desc.length; i++) {
marker = new google.maps.Marker({
map: map,
position: ultlng[i]
});
(function (i, marker) {
google.maps.event.addListener(marker, 'click', function () {
if (!infowindow) {
infowindow = new google.maps.InfoWindow();
}
infowindow.setContent("<html><body><div style="min-height:50px; max-width: 200px;">" + data[i].Description + "</div></body></html>");
infowindow.open(map, marker);
});
})(i, marker);
}
});
将ultlng []数组长度设为0，应为5
当5个5个元素被推入其中时
但是在$ post()之外显示的是长度
请给我解决方案，
在此先感谢
getting ultlng[] array length as 0 it should be 5
as 5 five elements are pushed into it
but outside $post() it is showing o lenght
Please get me solution for this,
Thanks in advance
