What is the simplest way to test if all of selected inputs are empty?
I get my inputs this way:
$myinputs = $('.inputstotest');
and would test single input with:
if ( $.trim($this.val()) == '' )
but how to test a group and return true if all are empty or false if any (at least one) is not empty?
Try this:
var $myinputs = $('.inputstotest');
var allEmpty = $myinputs.filter(function () {
return $.trim(this.value) != '';
}).length == 0;
console.log(allEmpty);
( In order to test, enter some values in the HTML markup, run the fiddle again and check in the console.)
This is just like my answer to the previous question, except the sense of the test is reversed.
var result = true;
$('.inputstotest').each(function() {
if ($.trim($(this).val())) != '') {
result = false;
return false; // Terminate the .each loop
}
});
return result;
You can try
$(".inputstotest input").each(function(){
if ($.trim($(this).val()).length == 0){
//do something
}
else{
//do something
}
});
