我想将文本框中给出的值存储在变量中。我是 javascript 的初学者。请帮帮我。这是我的代码。
<!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>
