Why condition does not work properly? for example enter numbers 3,4,5,6 in input(text)

JavaScript
1 
<input type="text" value="" id='a'>
    <br>
 <input type="button" value="15" id='b'>
<br>
 <input type="button" value="" id='c'>
/*query cods*/
$(document).ready(function(){$('#c').click(function(){
   
     a=document.getElementById('a').value;
    b=document.getElementById('b').value;
    if(a>b){
        alert('no')
    }
    else{
        alert('yes')
    }
    
})})

since you didn’t post the HMTL, it could be anything.

@amir1313: you need to format your code to have it show up correctly in your posts.

You can highlight your code, then use the </> button in the editor window, which will format it.

Or you can place three backticks ``` (top left key on US/UK keyboards) on a line before your code, and three on a line after your code. I find this approach easier, but unfortunately some European and other keyboards don’t have that character.

<input type="text" value=0 id='a'>
    <br>
 <input type="button" value=15 id='b'>
<br>
 <input type="button" value="" id='c'>

Those values are always strings, not numbers. Try

var a = Number(document.getElementById('a').value);
var b = Number(document.getElementById('b').value);

Is there another thread on this topic or was this thread just edited? I just posted a response about 10 minutes ago to one that had this code:

<html>
   <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
   <body> 
    
<input type="text" value=0 id='a'>
    <br>
 <input type="button" value=15 id='b'>
<br>
 <input type="button" value="" id='c'>
<script>
       
       $(document).ready(function(){$('#c').click(function(){
   
     a=document.getElementById('a').value;
    b=document.getElementById('b').value;
    if(a>b){
        alert('no')
    }
    else{
        alert('yes')
    }
    
})})
       
       </script>
   
    </body>

</html>

stating that the value of the inputs were strings, but it seems to have disappeared.

Thanks for your help

Yes there is. I’ll merge the two topics.

@amir1313: please do not start multiple threads on the same subject, as it leads to exactly this kind of confusion.

The value of an input is a string, not a number. Would that have an effect on the result of the comparison?
