<script> function join(){ msgBox.style.display="block" layer.style.display="none" } function index(){ location.href="./index.html" } var send=document.querySelector(".send") function hq(){ var del=document.querySelectorAll(".del") var top1=document.querySelectorAll(".top") for(let i=0;i<del.length;i++){ del[i].onclick=function(){ this.parentNode.parentNode.parentNode.remove() } top1[i].onclick=function(){ this.parentNode.parentNode.parentNode.parentNode.insertBefore(this.parentNode.parentNode.parentNode,this.parentNode.parentNode.parentNode.parentNode.firstChild) } } } hq() // var face=document.querySelectorAll("#face img") for(let i=0;i<face.length;i++){ face[i].onclick=function(){ for(let t=0;t<face.length;t++){ face[t].classList.remove('current'); } this.className="current" } }解释代码
这段代码是一个简单的聊天室页面的前端代码。具体来说,这段代码实现了以下功能:
1. 定义了 `join()` 函数,当用户点击加入聊天室按钮时,将消息框(`msgBox`)显示出来,并将遮罩层(`layer`)隐藏起来。
2. 定义了 `index()` 函数,当用户点击返回首页按钮时,将页面重定向到 `index.html`。
3. 定义了 `send` 变量,用于获取发送消息的按钮。
4. 定义了 `hq()` 函数,用于设置每条聊天记录的删除和置顶功能。具体来说,当用户点击删除按钮时,将该条记录从页面中删除;当用户点击置顶按钮时,将该条记录移动到页面的最顶端。
5. 定义了 `face` 变量,用于获取表情图片。当用户点击一个表情时,将该表情设置为当前选中状态,并将其他表情的选中状态清除。
需要注意的是,这段代码只包含了前端部分的实现,后端部分的实现并没有包含在内。
updateMapPoint: function(ev) { if (!($(".bootstrap-datetimepicker-widget").hasClass("picker-open"))) { var e = document.getElementById("idtimezone"); var Index = e.options[e.selectedIndex].value; var group = e.options[e.selectedIndex].parentNode.label; if (group != "ManualOffset") { if(typeof this.map !== 'undefined' && this.map !== null){ var offset = this.map.offset(), x = ev.pageX - offset.left, y = ev.pageY - offset.top, px = x / this.map.outerWidth(), py = y / this.map.outerHeight(), dist, closestDist = 100, closestPoint, i; for (i = 0; i < this.mapPoints.length; i++) { dist = this.mapPoints[i].distance(px, py); if (dist < closestDist) { closestPoint = this.mapPoints[i]; closestDist = dist; } } if (closestPoint) { this.newPoint(closestPoint); } } } } },将此段代码转换成Vue3+Ts语法
```
updateMapPoint(ev: MouseEvent): void {
if (!($(".bootstrap-datetimepicker-widget").hasClass("picker-open"))) {
const e = document.getElementById("idtimezone") as HTMLSelectElement;
const Index = e.options[e.selectedIndex].value;
const group = e.options[e.selectedIndex].parentNode.label;
if (group != "ManualOffset") {
if (typeof this.map !== 'undefined' && this.map !== null) {
const offset = this.map.offset();
const x = ev.pageX - offset.left;
const y = ev.pageY - offset.top;
const px = x / this.map.outerWidth();
const py = y / this.map.outerHeight();
let dist: number;
let closestDist = 100;
let closestPoint: any;
let i: number;
for (i = 0; i < this.mapPoints.length; i++) {
dist = this.mapPoints[i].distance(px, py);
if (dist < closestDist) {
closestPoint = this.mapPoints[i];
closestDist = dist;
}
}
if (closestPoint) {
this.newPoint(closestPoint);
}
}
}
}
}
