title: Javascript: Is there a limit to "else if" statements?
body: <p>I am getting value from a text field. I have one if and several else if statement.</p>
  
  <p>The problem the last else if doesn't execute even if the condition is true.</p>
  
  <p>If I change the last else if to if it executes and gives alert. When I change that back to else if the statement doesn't execute. The else if before that is fine as it's firing/executing on a particular condition.</p>
  
  <pre><code>function Valcheck()
  {
  
  var txtVal = document.getElementById("sometextField").value;
  
  
  
  if(txtVal =="%") 
      {
  
          alert("% is only allowed with other characters.");
          return;
      }       
  
      else if(txtVal.indexOf("%") != -1) 
      {
          if((txtVal.indexOf('%')) != (txtVal.length-1)) 
          {
              alert(" % is only allowed at the end.");
              return;
          }       
      } 
      else if(txtVal.indexOf(",") != -1) 
      {
          alert("Comma or comma separated values are not allowed.");
          return;
  
      } 
      else if(( txtVal.length  &gt;0) &amp;&amp;  (txtVal.indexOf("%") == -1)) 
      {
          alert("Please enter % at the end of the value.");
          return;
      }            
  
      else if( txtVal.length &gt; 11 ) 
      {
  
          alert(" Value can't be greater than 11 characters.");
          return;
  
      }
  
  }
