Javascript help - Haarek - 05-27-2019
How do I make it possible for a user of the site to input the values?
I get I have to use <input> with a form but I can't get the js to reference the name, id or action.
Is php the solution?
Code:
<html><body><script>
var height = 140
var storySize = 2.8
var getStories = function(storyCount){
storyCount = height / storySize
console.log("The height of the building is " + height + "m")
console.log("The building has " + Math.trunc(storyCount) + " stories")
console.log("the height of each story is " + storySize +"m")
getStories()
</script>
</body>
</html>I have tried 2 days now on and off.

<form>
<input name="numb" type="number">
<button onclick="getValue()">run</button>
</form>
<script>
function getValue() {
var x = document.getElementsByName("numb")[0].tagName;
document.getElementById('show').innerHTML = x;
getStories()
}
var height
var storySize = 2.8
var getStories = function(storyCount){
storyCount = height / storySize

}
</script>
<p id="show"></p>
</body>

Remove the <form> tags, that may help
Also try
var x = document.getElementById("numb").value;
You shouldn't need to put an array value on it

Thanks for the help. For future refrence that doesn't work as you'd expect it to.
You have to use a query selector with an addEventListener.
It took me a long time to figure it out
