How to check all input boxes are not empty or equal to 0?
Date : March 29 2020, 07:55 AM
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!');
}
}

Javascript style empty input boxes
Date : March 29 2020, 07:55 AM
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
