I have a viewmodel with the following property:
public class CompanyDetailsViewModel
{
[Required(ErrorMessage = "A Company Name is required")]
[Display(Name = "Company Name:")]
[StringLength(100)]
public string CompanyName { get; set; }
...
public IList<SuburbAndPostcode> SuburbAndPostcodesList { get; set; }
}
The list was created from this POCO class:
public class SuburbAndPostcode
{
[Key]
public int SuburbsAndPostcodesId { get; set; }
public string Suburb { get; set; }
public string PostCode { get; set; }
public State State { get; set; }
}
This is the state object:
public class State
{
[Key]
public int StateId { get; set; }
public string ShortName { get; set; }
public string Name { get; set; }
public virtual ICollection<CompanyDetail> CompanyDetails { get; set; }
}
I am trying to create a variable with the suburb and postcode properties as a list that I can use for an autocomplete function however I cant seem to assign the Model.SuburbsAndPostCodesList to a variable.
I have tried various javascript options indicated from other questions on this forum like here .
I would like to have a javascript variable that represents the list and I have tried just setting:
var suburbs = @Model.SuburbAndPostcodesList
I've tried using json and I have tried looping through the Model but get an error saying that the variable "test" is out of context:
var test =[];
@for (int i = 0; i < Model.SuburbAndPostcodesList.Count; i++)
{
test[i]=...
}
I have also tried using "push" and ".Encode".
I would like to know how to assign this list of strings and state object to a javascript variable?
Use Ajax Call to achieve Auto-complete functionality
$(document).ready(function () {
$("#txtPostcodes").keyup(function () {
//AutoComplete the Results
$("#txtPostcodes").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "../ControllerName/ActionName",
data: "{'input':'" + document.getElementById('txtPostcodes').value + "'}",
dataType: "json",
success: function (data) {
if (data != null) {
var suburbs = data;
}
},
error: function (result) {
}
});
}
});
}
});
});
In the end I simply equated the various members of the viewmodel list and build up a javascript multi dimensional array for the autocomplete function. Here it is:
var suburbs = [
@for (var i = 0; i < Model.SuburbAndPostcodesList.Count; i++) {
<text>{
id: "@Model.SuburbAndPostcodesList[i].SuburbsAndPostcodesId",
suburb: "@Model.SuburbAndPostcodesList[i].Suburb",
postCode: "@Model.SuburbAndPostcodesList[i].PostCode",
state: "@Model.SuburbAndPostcodesList[i].State.ShortName"
}@(i == Model.SuburbAndPostcodesList.Count - 1 ? "" : ",")</text>
}
];
$("#Suburb").autocomplete({
source: function (req, responseFn) {
var re = $.ui.autocomplete.escapeRegex(req.term);
var matcher = new RegExp("^" + re, "i");
var a = $.grep(suburbs, function (item, index) {
return matcher.test(item.suburb);
});
a = $.map(a, function (x) {
return {
label: x.suburb + " - " + x.postCode,
value: x.suburb,
suburbDetails: x
};
});
responseFn(a);
},
select: function (value, data) {
if (typeof data == "undefined") {
} else {
$("#Postcode").val(data.item.suburbDetails.postCode);
}
},
change: function (event, ui) {
if (!ui.item) {
$("#Suburb").val("");
$("#Postcode").val("");
}
}
});
