下面的代码演示了JavaScript中do…while循环语句的使用方法
<!DOCTYPE html>
<html>
<body>
<p>Click the button to loop through a block of as long as <em>i</em> is less than 5.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction()
{
var x="",i=0;
do
{
x=x + "The number is " + i + "<br>";
i++;
}
while (i<5)
document.getElementById("demo").innerHTML=x;
}
</script>
</body>
</html>
输出结果如下
The number is 0 The number is 1 The number is 2 The number is 3 The number is 4
