How can I check if all the elements inside a form "textbox, checkbox, textarea, select, file" are not empty?
Just use: $("input:empty"). length == 0; If it's zero, none are empty.
To check if an input is empty in React:Call the trim() method on the field's value. Access the length property on the value. If the field's value has a length of 0 , then it is empty, otherwise it isn't.
You can see if any are empty like this:
$(":input").each(function() { if($(this).val() === "") alert("Empty Fields!!"); });
You can read on the :input selector here
for a more specific answer, if you only want those types, change the selector like this:
$(":text, :file, :checkbox, select, textarea").each(function() { if($(this).val() === "") alert("Empty Fields!!"); });
