init: function (t, e) { if (t && (this.id = t, this.type = e), "info" == this.type || "else" == this.type) this.info(t); else if ("cross" == this.type) { var o = this.$storage.getObj("crossObj"); for (var n in o) "title" != n ? "content" != n ? "parentid" != n ? "userid" != n ? "username" != n ? "isdone" != n || (this.ruleForm.isdone = o[n], this.ro.isdone = !0) : (this.ruleForm.username = o[n], this.ro.username = !0) : (this.ruleForm.userid = o[n], this.ro.userid = !0) : (this.ruleForm.parentid = o[n], this.ro.parentid = !0) : (this.ruleForm.content = o[n], this.ro.content = !0) : (this.ruleForm.title = o[n], this.ro.title = !0) } this.isdoneOptions = "开放,关闭".split(",") },

这段代码看起来像是一个对象的初始化函数,其中包含了一些条件语句和存储读取操作。具体来说,如果类型是"info"或"else",则调用info函数进行初始化;如果类型是"cross",则从本地存储中获取一个名为"crossObj"的对象,并根据对象的属性值为ruleForm对象的各个属性赋值,同时设置ro对象的对应属性为true。最后,将"isdoneOptions"属性设置为一个包含"开放"和"关闭"两个字符串的数组。

以下是对应的后端Java代码,按照三层架构来实现:
1. DAO层代码
WarehouseDao.java
```
package com.example.warehousemanagement.dao;
import java.util.HashMap;
import java.util.Map;
public class WarehouseDao {
private static Map<String, String[]> warehouseMap = new HashMap<>();
public String[] getWarehouseByBarcode(String barcode) {
return warehouseMap.get(barcode);
}
public void addWarehouse(String barcode, String warehouseNo) {
String[] warehouseNumbers = warehouseMap.getOrDefault(barcode, new String[0]);
String[] newWarehouseNumbers = new String[warehouseNumbers.length + 1];
System.arraycopy(warehouseNumbers, 0, newWarehouseNumbers, 0, warehouseNumbers.length);
newWarehouseNumbers[newWarehouseNumbers.length - 1] = warehouseNo;
warehouseMap.put(barcode, newWarehouseNumbers);
}
public Map<String, String[]> getAllWarehouses() {
return warehouseMap;
}
}
```
2. Service层代码
WarehouseService.java
```
package com.example.warehousemanagement.service;
import com.example.warehousemanagement.dao.WarehouseDao;
import java.util.Map;
public class WarehouseService {
private WarehouseDao warehouseDao;
public WarehouseService() {
warehouseDao = new WarehouseDao();
}
public String[] getWarehouseByBarcode(String barcode) {
return warehouseDao.getWarehouseByBarcode(barcode);
}
public void addWarehouse(String barcode, String warehouseNo) {
warehouseDao.addWarehouse(barcode, warehouseNo);
}
public Map<String, String[]> getAllWarehouses() {
return warehouseDao.getAllWarehouses();
}
}
```
3. Controller层代码
WarehouseController.java
```
package com.example.warehousemanagement.controller;
import com.example.warehousemanagement.service.WarehouseService;
import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import java.util.Map;
@Path("warehouse")
public class WarehouseController {
private WarehouseService warehouseService;
public WarehouseController() {
warehouseService = new WarehouseService();
}
@GET
@Path("{barcode}")
@Produces(MediaType.TEXT_PLAIN)
public Response getWarehouseByBarcode(@PathParam("barcode") String barcode) {
String[] warehouseNumbers = warehouseService.getWarehouseByBarcode(barcode);
if (warehouseNumbers == null) {
return Response.status(Response.Status.NOT_FOUND).entity("Warehouse not found").build();
} else {
return Response.ok(warehouseNumbers[0]).build();
}
}
@POST
@Path("{barcode}/{warehouseNo}")
public Response addWarehouse(@PathParam("barcode") String barcode, @PathParam("warehouseNo") String warehouseNo) {
warehouseService.addWarehouse(barcode, warehouseNo);
return Response.ok().build();
}
@GET
@Produces(MediaType.APPLICATION_JSON)
public Response getAllWarehouses() {
Map<String, String[]> warehouseMap = warehouseService.getAllWarehouses();
return Response.ok(warehouseMap).build();
}
}
```
4. 启动类代码
WarehouseManagementApplication.java
```
package com.example.warehousemanagement;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.servlet.ServletContainer;
import org.glassfish.jersey.servlet.ServletProperties;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
@WebServlet(name = "WarehouseManagementApplication", urlPatterns = {"/api/*"})
public class WarehouseManagementApplication extends HttpServlet {
@Override
public void init() throws ServletException {
ResourceConfig config = new ResourceConfig();
config.packages("com.example.warehousemanagement.controller");
ServletContainer container = new ServletContainer(config);
this.getServletContext().setAttribute(ServletProperties.JAXRS_APPLICATION_CONTEXT_ATTRIBUTE, config);
}
}
```
5. web.xml代码
```
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<servlet>
<servlet-name>WarehouseManagementApplication</servlet-name>
<servlet-class>com.example.warehousemanagement.WarehouseManagementApplication</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>WarehouseManagementApplication</servlet-name>
<url-pattern>/api/*</url-pattern>
</servlet-mapping>
</web-app>
```
6. warehouse.js代码 (无需修改)
```
function getWarehouseNo() {
let barcode = document.getElementById("barcode").value;
let xhr = new XMLHttpRequest();
xhr.open("GET", "/api/warehouse/" + barcode, true);
xhr.onreadystatechange = function() {
if (this.readyState === 4 && this.status === 200) {
document.getElementById("warehouseNo").innerHTML = "Warehouse Number: " + this.responseText;
}
};
xhr.send();
}
function addWarehouse() {
let barcode = document.getElementById("manualBarcode").value;
let warehouseNo = document.getElementById("manualWarehouseNo").value;
let xhr = new XMLHttpRequest();
xhr.open("POST", "/api/warehouse/" + barcode + "/" + warehouseNo, true);
xhr.onreadystatechange = function() {
if (this.readyState === 4 && this.status === 200) {
alert("Warehouse added successfully");
}
};
xhr.send();
}
function getAllWarehouse() {
let xhr = new XMLHttpRequest();
xhr.open("GET", "/api/warehouse", true);
xhr.onreadystatechange = function() {
if (this.readyState === 4 && this.status === 200) {
let data = JSON.parse(this.responseText);
let warehouseList = document.getElementById("warehouseList");
for (let warehouse in data) {
let list = document.createElement("li");
list.innerHTML = warehouse + ": " + data[warehouse].join(", ");
warehouseList.appendChild(list);
}
}
};
xhr.send();
}
getAllWarehouse();
```
注意事项:
1. 需要在pom.xml中添加Jersey依赖
2. 需要在web.xml中添加Jersey Servlet的配置
3. 需要启动Tomcat等Servlet容器来运行这个项目
function webAudio(options){ //public this.volume = parseInt(options.volume || 100) ; // 音量控制单元,值为Number类型,范围为0-100 this.url = options.url || '' ; // 音频资源url,值类型为String类型 this.autoPlay = !!options.autoPlay; // 是否加载完成自动播放,值类型为Boolean类型 this.loopPlay = !!options.loopPlay; // 是否循环播放,值类型为Boolean类型 //private this.buffer = null; this.context = null; this.sourceAudio = null; this.gainNode = null; this.loadReady = false; //初始化 this.init = function () { window.AudioContext = window.AudioContext || window.webkitAudioContext || window.mozAudioContext || window.msAudioContext; if(!AudioContext){ console.error("您的浏览器不支持HTML5 audio API"); return } this.context = new AudioContext(); this.loadResource(); } //下载音频资源 this.loadResource = function () { var _this = this; var xhr = new XMLHttpRequest(); xhr.open('GET',this.url,true); xhr.responseType = 'arraybuffer'; xhr.onload = function () { _this.context.decodeAudioData(xhr.response,function (buffer) { _this.buffer = buffer; _this.prepareAudio(); this.loadReady = true; }) } xhr.send(); } //是否自动播放 this.prepareAudio = function () { this.autoPlay ? this.startAudio() : ''; } //创建音频 this.createAudio = function () { this.sourceAudio = this.context.createBufferSource();//创建一个音频源 相当于是装音频的容器 this.sourceAudio.buffer = this.buffer;// 告诉音频源 播放哪一段音频 this.gainNode = this.context.createGain();//调节音量 this.sourceAudio.connect(this.gainNode); this.changeVolume();//声音 this.sourceAudio.loop = this.loopPlay;//循环 this.gainNode.connect(this.context.destination);// 连接到输出源 } //重新播放 this.startAudio = function () { this.createAudio(); this.sourceAudio.start(0);//开始播放 } //改变音量 this.changeVolume = function (num) { num = num || 0; this.gainNode.gain.value = (this.volume += num) / 100; } //播放转为暂停 this.pauseAudio = function () { this.gainNode.disconnect(this.context.destination) } //暂停转为播放 this.playAudio = function () { this.gainNode.connect(this.context.destination) } //停止播放 this.stopAudio = function () { this.sourceAudio.stop() } //减小声音 this.decVolume = function () { if(this.volume >= 10){ this.changeVolume(-10); } } //增大声音 this.ascVolume = function () { if(this.volume <= 90){ this.changeVolume(10); } } //静音 this.quietVolume = function () { this.gainNode.gain.value = 0; } //静音恢复 this.recoverVolume = function () { this.changeVolume() } //当前音量 this.getVolume = function () { return (this.gainNode.gain.value).toFixed(2) * 100; } this.init(); return this; } window.test = new webAudio({ volume:100, url:'1.mp3', autoPlay:true, loopPlay:true }); //控制台事件 var pauseEle = document.getElementById("pause"); pauseEle.onclick = function() { if (pauseEle.alt === 'Pause') { test.pauseAudio(); } else { test.playAudio(); } }增加播放暂停图片切换
可以将HTML代码中的播放暂停按钮的img标签的src属性设为一个变量,然后在JavaScript中根据当前状态切换该变量的值,从而实现图片切换。例如,可以在JavaScript中添加一个togglePlayPause函数:
```
function togglePlayPause() {
var playPauseButton = document.getElementById("play-pause-button");
if (playPauseButton.src === "play.png") {
playPauseButton.src = "pause.png";
} else {
playPauseButton.src = "play.png";
}
}
```
并在createAudio函数中调用该函数:
```
this.createAudio = function () {
this.sourceAudio = this.context.createBufferSource();
this.sourceAudio.buffer = this.buffer;
this.gainNode = this.context.createGain();
this.sourceAudio.connect(this.gainNode);
this.changeVolume();
this.sourceAudio.loop = this.loopPlay;
this.gainNode.connect(this.context.destination);
togglePlayPause();
}
```
这样,每次播放或暂停音频时,都会切换播放暂停按钮的图片。需要在HTML代码中给该按钮添加一个id属性为"play-pause-button",并将src属性设为默认的播放按钮图片路径。
