SSM项目实战-前端-在Index.vue中展示第一页数据

1、util/request.js

import axios from "axios";let request = axios.create({baseURL: "http://localhost:8080",timeout: 50000
});export default request

2、api/schedule.js

import request from "../util/request.js";export let getScheduleList = (queryvo) => {return request.get(`/schedule/${queryvo.pageNum}`,{params:{uid:queryvo.uid}})
};
export let updateSchedule=data=>{return request.put("/schedule",data)
}
export let saveSchedule=data=>{return request.post("/schedule",data)
}
export let delSchedule=id=>{return request.delete(`/schedule/${id}`)
}

3、Index.vue

<template><el-container><el-row><el-button type="primary" plain @click="toAdd">新增</el-button></el-row><el-table :data="schedulePageInfo.list" style="width: 100%"><el-table-column label="编号" width="180"><template #default="scope"><div style="display: flex; align-items: center"><span style="margin-left: 10px">{{ scope.row.sid }}</span></div></template></el-table-column><el-table-column label="学习计划" width="180"><template #default="scope"><div style="display: flex; align-items: center"><span style="margin-left: 10px">{{ scope.row.title }}</span></div></template></el-table-column><el-table-column label="是否完成" width="180"><template #default="scope"><div style="display: flex; align-items: center"><span style="margin-left: 10px">{{ scope.row.completed ?

7、模板字符串 ``

在ES6（ECMAScript 2015）中，模板字符串是一种新的字符串类型，它使用反引号（`）来定义，可以包含嵌入式表达式（即${expression}）。模板字符串的出现为JavaScript提供了更灵活和强大的字符串处理能力。

模板字符串的主要作用包括：

格式化字符串：通过使用嵌入式表达式，可以将变量或表达式的值直接嵌入到字符串中。这使得字符串的格式化更为方便和直观。例如：
let name = "John";  
let greeting = `Hello, ${name}!`; // 输出 "Hello, John!"
多行字符串：模板字符串可以包含多行内容，这对于处理多行文本或代码非常有用。例如：
let multiLineString = `This is a   
multi-line   
string.`; // 输出一个跨越多行的字符串
字符串插值：通过使用嵌入式表达式 ${expression}，可以在字符串中插入变量或表达式的值。这使得字符串的动态生成更为简单。例如：
let name = "John";  
let message = `My name is ${name}.`; // 输出 "My name is John."
转义字符：模板字符串中，反斜杠（\）用于转义字符，可以用来表示特殊字符（如换行符、制表符等）。例如：
let escapedString = `\n represents a new line.`; // 输出 "\ represents a new line."
在实际开发项目中，模板字符串可以帮助你更方便地处理字符串，提高代码的可读性和可维护性。特别是在处理复杂的字符串逻辑时，模板字符串可以使得代码更加清晰和易于理解。
