具體如下：
下面的代碼演示了JS數(shù)組通過push方法添加一個元素到數(shù)組末尾
<!DOCTYPE html>
<html>
<body>
<p id="demo">
Click the button to add a new element to the array.
</p>
<button onclick="myFunction()">Try it</button>
<script>
var fruits = ["Banana","Orange","Apple","Mango"];
function myFunction()
{
fruits.push("jb51.net")
var x=document.getElementById("demo");
x.innerHTML=fruits;
}
</script>
</body>
</html>
上面的代碼執(zhí)行后輸出如下結(jié)果
Banana,Orange,Apple,Mango,jb51.net
