Question

Good morning, I have a doubt.
I have a function that adds a click the User, the side of my input

Plus this gives an error. I wanted just once even if adicionace a person clicks the button several times the action. Do you have a scan after input if not add another

My code.

//th = Name of the input that will add, at the low <SPAN>

      if(d.length == 0){
          $(th).after('<SPAN class="erro">'+txt+'</SPAN>');
          this.focus();
          return false;
      }

I would be very grateful for the help. 🙂

You should search for span.error first with $.find, and add it only if it isn’t there already:

  if(d.length == 0){
      var errorSpan = $(th).find("span.error").length;
      if(!errorSpan) {
          $(th).after('<SPAN class="erro">'+txt+'</SPAN>');
          this.focus();
      }
      return false;
  }
