[英]JSON client side
The following code block runs without error but the 'data' is returned as what appears to be a single 1 dimensional record. 以下代码块运行无误,但返回的“数据”似乎是单个一维记录。 The code returns one record with all the records in it, ie if i debug and output 'data' variable to the immediate window i get :
该代码返回其中包含所有记录的一条记录,即,如果我调试并将“ data”变量输出到立即窗口,则得到:
?data
{...}
[0]: "127"
[1]: "Barnesmore"
[2]: "-7.934532"
[3]: "54.692091"
[4]: "75"
[5]: "Beinn an Tuirc"
[6]: "-5.583115"
[7]: "55.565631"
[8]: "78"
[9]: "Beinn Tharsuinn"
[10]: "-4.251795"
[11]: "57.805856"
[12]: "77"
[13]: "Black Law"
[14]: "-3.705482"
[15]: "55.77749"
[16]: "1"
[17]: "BlackLaw Phase 3"
[18]: "323232"
[19]: "121212"
20: null
21: null
22: null
23: null
length: 24
but element [0] to [3] is a record and [4] to [7] is a record and so on. 但是元素[0]至[3]是记录,[4]至[7]是记录,依此类推。 How do i change my code to just loop the records?
如何更改代码以仅循环记录? MAny thanks for reading, here is my code snippet below :::
谢谢您的阅读,这是我下面的代码段:::
var index = 0;
var itemData;
var url = $("#AbsolutePath").val() + "Site.mvc/GetMapList/" + "?siteDescription=" + $('#SearchTextBox').val();
var arr = $.getJSON(url, null, function(data) {
$.each(data, function(index, itemData) {
debugger;
alert(itemData);
});
});
CONTROLLER CODE: 控制器代码:
public JsonResult GetMapList(string siteDescription)
{
var allSites = _siteRepository.FindAllSites();
//Get all Sites that contain the value in sitedescription
var searchResults = (from s in allSites
where s.SiteDescription.StartsWith(siteDescription)
select s);
// We need an object client side to loop through in Javascript and add all the tags to the Map for each site in Search Results
string[,] sArray = new string[searchResults.Count(), 4];
int i = 0;
foreach (Site item in searchResults)
{
if (item.SiteLocation == null || item.SiteLocation.SiteLocationId == 0)
{ }
else
{
if ((item.SiteLocation.Latitude != 0) && (item.SiteLocation.Longitude != 0))
{
sArray[i, 0] = item.SiteId.ToString();
sArray[i, 1] = item.SiteDescription.ToString();
sArray[i, 2] = item.SiteLocation.Longitude.ToString();
sArray[i, 3] = item.SiteLocation.Latitude.ToString();
i++;
}
}
}
return this.Json(sArray);
}
? ? Something on the lines of
一些东西
for(i=0; i < data.length; i + 4 ){
var myrecord = "Record Number: " + data[i] + ", Place: " + data[i + 1] + ", Longitude: " + data[i + 2] + ", Latitude: " + data[i + 3];
alert (myrecord);
}
