I am currently utilizing Bootstrap in order to implement some visual validation for the form fields:
<div class="span1" style="min-width: 20px;">
<input type="number" min="0.1" max="40" step="0.1" value="1" data-field="numberField" class="input-mini" style="width: 40px">
</div>
Is there a way for the text box to display a red highlight when the input is not numeric, or contains commas or dots (euro format)?
Similar to the response above (upvoted) as it accomplishes most of the task, with the assumption based on your feedback that you're looking to add Bootstrap's warning class to the input element.
All the necessary classes can be found in Bootstraps' official documentation at getbootstrap.com. You'll need to apply the input classes, which are typically located on the "components" section of the website.
To achieve this, utilize jQuery's addClass() function following the instructions provided by @Reza:
var value = $("#inputId").val();
if(Math.floor(value) == value && $.isNumeric(value))
$("#inputId").addClass('input-warning');
Implement an onBlur event triggering a CSS style when certain conditions are met:
let userInput = $("#inputId").val();
if(Math.floor(userInput) == userInput && $.isNumeric(userInput)) {
$("#inputId").css('border', '1px solid red');
}
