原题目大概是通过一个固定的数组.里面有四个字符串,在页面上打印出不包含A和a的字符串
let fruit = new Array("apple", "ornge" ,"pech" ,"banana");
判断的数值是死的,我就在想,能不能把条件变为的态度的,打印在当前页面
<body>
条件1为:<input type="text" id="conditions1" /><br />
条件2为:<input type="text" id="conditions2" /><br />
<button onclick="find()">查询</button>
<br />
数组:<span id="sp"></span><br />
不包含:<span id="sp2"></span>
<script type="text/javascript">
//数组
let fruit = new Array("apple", "ornge", "pech", "banana");
//打印输出
let fi = fruit;
document.getElementById("sp").innerHTML = fi;
function find() {
//获取文本框值
let name1 = document.getElementById("conditions1").value;
let name2 = document.getElementById("conditions2").value;
//控制台打印值
console.log(conditions1);
console.log(conditions2);
//创建了一个数组
let storage = new Array();
//循环打印判断
for (let i = 0; i < fruit.length; i++) {
if (fruit[i].indexOf(conditions1) == -1 && fruit[i].indexOf(conditions2) == -1) {
//打印输出
//把fruit[i]也就是符合的值添加到名字为j的数组中
storage.push(fruit[i]);
//打印出数组
document.getElementById("sp2").innerHTML = storage;
}
}
}
</script>
</body>
