c# - 如何将 C# List<string[]> 转换为 Javascript 数组？

Question

我有一个数据表，我正在将其转换为列表、对其进行序列化并使用 View 模型将其传递到我的 View 。

我的 View 模型如下所示:

public class AddressModel
{
    public string Addresses { get; set; }
}

我的 Controller 操作如下所示:

AddressModel lAddressGeocodeModel = new AddressGeocodeModel();
List<string[]> lAddresses = new List<string[]>();

string lSQL = " select Address1, CityName, StateCode, ZipCode " +
                      " from AddressTable  ";

// Convert the data to a List to be serialized into a Javascript array.
//{
...data retrieval code goes here...
//}
foreach (DataRow row in AddressTable.Rows)
{
    string[] lAddress = new string[5];
    lAddress[1] = row["Address1"].ToString();
    lAddress[2] = row["CityName"].ToString();
    lAddress[3] = row["StateCode"].ToString();
    lAddress[4] = row["ZipCode"].ToString();
    lAddresses.Add(lAddress);
}

lAddressGeocodeModel.UnitCount = lAddresses.Count().ToString();
// Here I'm using the Newtonsoft JSON library to serialize my List
lAddressGeocodeModel.Addresses = JsonConvert.SerializeObject(lAddresses);

return View(lAddressModel);

然后在我看来我得到以下地址字符串:

[["123 Street St.","City","CA","12345"],["456 Street St.","City","UT","12345"],["789 Street St.","City","OR","12345"]]

我应该如何将驻留在 Razor 模型中的序列化字符串放入 javascript 数组中？

Answer 1

您可以直接将值注入(inject) JavaScript:

//View.cshtml
<script type="text/javascript">
    var arrayOfArrays = JSON.parse('@Html.Raw(Model.Addresses)');
</script>

参见 JSON.parse , Html.Raw

或者，您可以通过 Ajax 获取值:

public ActionResult GetValues()
{
    // logic
    // Edit you don't need to serialize it just return the object

    return Json(new { Addresses: lAddressGeocodeModel });
}

<script type="text/javascript">
$(function() {
    $.ajax({
        type: 'POST',
        url: '@Url.Action("GetValues")',
        success: function(result) {
            // do something with result
        }
    });
});
</script>

参见 jQuery.ajax
