Hope this helps Use For Loop with a number of box that you need, and validate when the model is null, use a For loop
 @{ 
    if (Model == null)
    { 
      int textboxnumber = 6;//change value on behind code or put a constant number 
      for(int i=0;i<textboxnumber;i++) 
      { 
        <input type="text" placeholder="textbox empty"/> 
      } 
    } 
  }

will be helpful for those in need I'm getting the user to enter coefficients (as strings) for terms from a constant (e.g. 2) all the way up to a sextic (e.g. 3X^6). , Simply check for the empty string and replace with '0'.
var
  Coeff: string;
....
Coeff := CoefficientEdit[i].CoEditBox.Text;
if Coeff = '' then
  Coeff := '0';

To fix this issue I have a form with many input boxes. I want to make a function that will go through each box and determine if any of the boxes are 0 or empty. , try something like this:
function checkInputs() {

    var flag=0;
  var result = new Array();

    $("form#inputData :input[type=text]").each(function(){
        var input = $(this); 
        if(input.val() > 0 && input.val() !== '' ) {
            result.push(input.val());
        } 
    });

    if(result.length > 0){
        alert('thanks')
    } else {
        alert('error!'); 
    }

}

help you fix your problem Pretty simple, a somewhat verbose example so you see what is going on. .trigger() to set initial values. Added some dynamic inputs also.
jQuery('.myinputs').on('change','input.pretty', function() {
  let tmpval = $(this).val();
  let hasNoValue = tmpval == '';
  let isRequired = $(this).prop('required');
  $(this).toggleClass('empty', hasNoValue);
  $(this).toggleClass('not-empty', !hasNoValue);
  $(this).toggleClass('invalid', hasNoValue && isRequired);
})
$('.myinputs').append('<input class="pretty" type="text" />').append('<input class="pretty" type="text" required="true" />').append('<input class="pretty" type="text" required="true" value="dynamic" />');
$('input.pretty').trigger('change');
.empty {
  background-color: yellow;
}

.not-empty {
  background-color: #99FF99;
}

.invalid {
  background-color: #FF9999;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="myinputs">
<input class="pretty" type="text" />
<input class="pretty" type="text" />
<input class="pretty" type="text" required="true" />
<input class="pretty" type="text" required="true" />
<input class="pretty" type="text" value="howdy" />
<input class="pretty" type="text" />
</div>

How to generate an error when important input text boxes are empty


Tag : excel , By : desmiserables
Date : March 29 2020, 07:55 AM
it should still fix some issue I am creating a data entry userform that calculates loads (e.g.pipeloads, wind loads etc..). There are important text boxes that cannot be left unfilled. If the user clicks the command "Add Input" and there are some text boxes left unfilled, I want an error to be generated that forces the user to enter a value. , Maybe you can try this
Private Sub Continue_click()

Dim c as Control

    For Each c In Me.Controls
        If TypeName(c) = "TextBox" Then

            If Trim(c.Value) = "" Then
              MsgBox "Please fill out all required information", vbInformation
            Exit Sub
            End If

        End If
    Next c
End Sub
