I want to store the value given in the text box in a variable. I am beginner to javascript. Please help me out. Here s my code.
<!DOCTYPE html>
<html>
<body>
Days of Journey: <input type="text" id="doj" name="daysofjourney">
<input type="button" value="submit" onclick="dayscounter()">
<script language="javascript" type="text/javascript">
var travel = document.getElementById("doj").value;
function dayscounter() {
var days;
for(days = 1; days <= travel; days++) {
document.write(days);
}
}
</script>
</body>
</html>
You nearly had it already...
function dayscounter() {
var travel = document.getElementById("doj").value;
var days;
for(days=1;days<=travel;days++)
{
document.write(days);
}
}
The problem was, that your first assignment of the variable travel is made as soon as the HTML code is loaded. The user can't have made an input yet at that time, thus the variable stays empty. If you include document.getElementById("doj").value inside the function, you will get the value at that specific time you launch the function.
