一、场景
点击按钮将部分内容隐藏（收起），再点击按钮时将内容显示（展开）出来。
二、技术摘要
- js实现实现内容显示隐藏
- js动态给ul标签添加li标签
- js遍历数组
三、效果图
四、代码
js_block_none.js代码
var group1 = document.getElementById("group1");
var btn_group1 = document.getElementById("btn_group1");
function showHiddenGroup1() {
if (group1.style.display == "none") {
group1.style.display = "block";
btn_group1.innerText = "点击收起";
} else {
group1.style.display = "none";
btn_group1.innerText = "点击展开";
}
}
var group2 = document.getElementById("group2");
var btn_group2 = document.getElementById("btn_group2");
var ul_group2 = document.getElementById("ul_group2");
// 遍历数组1 js ul动态添加li
var otherParts = ['财务部', '行政部', '采购部', '商务部'];
for (let index in otherParts) {
let li = document.createElement('li')
li.textContent = otherParts[index];
ul_group2.appendChild(li);
}
// 遍历数组2 js ul动态添加li
// otherParts.forEach((part) =>{
// let li = document.createElement('li')
// li.textContent = part;
// ul_group2.appendChild(li);
// })
function showHiddenGroup2() {
if (group2.style.display == "none") {
group2.style.display = "block";
btn_group2.innerText = "点击收起";
} else {
group2.style.display = "none";
btn_group2.innerText = "点击展开";
}
}
