I am developing an ASP.NET core Razor application and I have a form that I am posting, but I don't want the page to reload on submit. I read that this can be avoided by using Ajax, but i'm not sure how to implement this.
This is my form:
<form id="bankDropdown" method="post">
<div>
<label class="ratings-text" for="bank">Select Bank:</label>
<select name="BankOptions" class="form-control ratings-text" style="width:21%" id="bank">
@foreach (var bank in Model.BankLists)
{
<option name="BankOptions" value="@bank.ShortName" id="selection">@bank.ShortName</option>
}
</select>
</div>
<br />
<div>
<label>Enter Start Date:</label>
<input type="date" asp-for="DateSelect.DateMonthYear1" class="DateMonthYear" name="DateMonthYear1">
<i data-toggle="tooltip" title="Set to first day of the month for optimal results" class="far fa-question-circle"></i>
</div>
<br />
<div>
<label>Enter End Date:</label>
<input type="date" asp-for="DateSelect.DateMonthYear" class="DateMonthYear" name="DateMonthYear" required>
<i data-toggle="tooltip" title="Set to last or current day of the month for optimal results" class="far fa-question-circle"></i>
</div>
<br />
<div>
<input class="ratings-button" type="submit" value="Submit"/>
</div>
</form>
This is my POST function in my page model:
public IActionResult OnPost(string DateMonthYear, string DateMonthYear1, string BankOptions)
{
CurrentDate = string.Format(DateMonthYear);
SelectBank = BankOptions;
BankLists = ModelService.RunBankList();
TotalBankCollections = ModelService.RunTotalBankCollection1(DateMonthYear);
TotalTransactionCounts = ModelService.RunTotalTransactionCount1(DateMonthYear1, DateMonthYear);
long floatTotalCount = 0;
int intVolumeCount = 0;
string stringTotalVolume = "";
//get individual bank monthly collections
foreach (var collection in TotalBankCollections)
{
if (BankOptions == collection.ShortName)
{
string myBank = collection.TotalCollection;
BankCollection = Convert.ToDecimal(myBank).ToString("#,###,###.##");
}
}
//get total collections from all the banks
foreach (var collection in TotalBankCollections)
{
floatTotalCount += (long)Convert.ToDouble(collection.TotalCollection);
string stringTotalCount = Convert.ToDecimal(floatTotalCount).ToString("#,###,###.##");
TotalCollectionCount = stringTotalCount;
}
//get individual monthly volume collections
foreach (var collection in TotalTransactionCounts)
{
if (BankOptions == collection.ShortName)
{
string myBank = collection.TotalCount;
MonthlyVolumeCount = Convert.ToDecimal(myBank).ToString("#,##0");
}
}
//get total transactions of all banks
foreach (var collection in TotalTransactionCounts)
{
intVolumeCount += int.Parse(collection.TotalCount);
stringTotalVolume = intVolumeCount.ToString("#,##0");
TotalVolumeCount = stringTotalVolume;
}
return Page();
}
This is what I have so far, I have never used Ajax before and I have a project deadline:
$.ajax({
type: "POST",
url: "/Identity/Account/Ratings",
contentType: 'application/json; charset=utf-8',
dataType: "json",
success: function (response) {
alert(response);
},
failure: function (response) {
alert(response);
}
});
Thanks for the help.
If you want to use ajax with post method in razor page,here is a demo: TestFormPost.cshtml(script):
$("#bankDropdown").on('submit', function (e) {
e.preventDefault();
$.ajax({
type: "POST",
url: "",
data: $("#bankDropdown").serialize(),
headers: { "RequestVerificationToken": $('input[name="__RequestVerificationToken"]').val() },
success: function (data) {
}
});
})
TestFormPost.cshtml.cs:
public class TestFormPostModel : PageModel
{
[BindProperty]
public List<Bank> BankLists { get; set; }
[BindProperty]
public DateSelect DateSelect { get; set; }
public IActionResult OnGet()
{
BankLists = new List<Bank> {
new Bank{ ShortName="bank1"},
new Bank{ ShortName="bank2"},
new Bank{ ShortName="bank3"}
};
return Page();
}
public IActionResult OnPost(string DateMonthYear, string DateMonthYear1, string BankOptions) {
return Page();
}
}
public class Bank
{
public string ShortName { get; set; }
}
public class DateSelect
{
public string DateMonthYear { get; set; }
public string DateMonthYear1 { get; set; }
}
you can prevent form submission by
$('form').on('submit',function(e){
e.preventDefault();
////then ajax call
})
