I need to provide a custom validation message for when user input invalidates the step = ".01"
Currently, the validation message is the default "Please enter a multiple of 0.01". How can I change this?
@Html.TextBoxFor(x => x.CostChanges[i].MyVariable, new { @class = "form-control", step = ".01" })
<span asp-validation-for="@Model.CostChanges[i].MyVariable" class="text-danger"></span>
Here is a demo(remove <span></span> in your code,and use a new span to put your error message):
html:
@Html.TextBoxFor(x => x.CostChanges[i].MyVariable, new { @class = "form-control", step = ".01", onblur = "check(this)",type="number" })
<span id="CostChanges_@(i)__MyVariable-error" class="text-danger field-validation-valid"></span>
js:
function check(input) {
if ($(input).attr("aria-invalid")) {
var id = $(input).attr("id") + "-error";
//put your custom error message to the text
$("#"+id).text("custom error message");
}
}
result:
