1. 写一个while循环, 输出一个数值数组所有的奇数
<html>
<head>
<title>js学习</title>
<meta charset="utf-8">
<script type="text/javascript">
var arr = [1,3,5,2,4,6,12,14,15,37];
var a = 0;
var lenth = arr.length;
while (a<lenth) {
if(arr[a]%2!==0){
console.log(arr[a])
}
a+=1;
}
</script>
</head>
<body>
</body>
</html>2.写一个对象字面量, 描述一款你喜欢的手机信息
<script type="text/javascript">
var myphone = {
pname:"ipone8plus",
pprice:6388,
pmade:'China'
};
console.log('手机***信息: '+ myphone.pname );
console.log('手机价格信息: '+ myphone.pprice );
console.log('手机产地信息: '+ myphone.pmade );
</script>3. 写一个函数表达式, 计算三个数之和
<script type="text/javascript">
var res = function sum(a,b,c){
return console.log(a+b+c);
};
res(11,33,55);
</script>
