Check if input value exist from unique input name

Question

I have an html input text like this :

<input type="text" name="address[5][firstname]">

i want to check if the value is exist only by input which contain a specific string like firstname. Here's what i've done so far:

if($( "input[name*='[firstname]']" ).length < 1){
   console.log('in');
}

if($( "input[name*='[firstname]']" ).length < 1){
   console.log('in');
}

Could you be specific? What do you want to do? Also, observe your console for any errors. — 31piy

Your selector is good but your if condition is wrong. You are checking < 1 but there is already an element matched and length is 1, hence the condition not satisfied. Change it to > 0

if($( "input[name*='[firstname]']" ).length > 0){
  alert('in');
}
