[SOLVED] html script variable assignment

html script variable assignment

So I have a script block:

<script>
var totalPopulation = 0;

for(xxxxx){
  totalPopulation = totalPopulation + xxx
}
</script>


<tr>
  <input type="text" name="censusPop" value=totalPopulation/>
<tr>

I'm still quite green to javascript. But is there a way to assign the value of a variable in a script block to a HTML element like input type? I know that the code is unreachable.

Solution

hope it will help you to understand how javascript work

<html>
<head>
<script>
    var totalPopulation = 0;

    function addAndShowPopulation(population) {
         totalPopulation = totalPopulation + population;

         var input_tag = getTag('my_input_id');
         input_tag.value = totalPopulation;
    }

    function startAdding() {
         addAndShowPopulation(10);

         setTimeout( function(){startAdding();},1000);
    }

    function getTag(id) {
       return document.getElementById(id);
    }

</script>
</head>
<body onload="startAdding();">

<div>
     <input type="text" id="my_input_id" name="censusPop" value="" placeholder="Total Population"/>

</div>
</body>
</html>
