继上篇文章的例子，改造一下
思路：
1.给“增加”按钮绑定点击事件，点击即增加可输入的一行空行
2.如果点击“删除”，就借助@row-click和event来删掉该行数据
效果：
1.点击“删除”按钮，把当前行数据删掉
2.点击“增加”按钮，新增一行，此处用push，所以空行加在最后面
3.输入数据，每个字段都输入时，校验通过（控制台没有录制进去，依然是有打印的）
代码：
html：
<div id="app">
<el-form class="base-form" ref="baseForm" :model="baseForm" :rules="rules" auto-complete="on">
<el-table ref="table-input" class="table" highlight-current-row :data="baseForm.demoList" @row-click="selectItem">

</el-form-item>
</template>
</el-table-column>
<el-table-column prop="" label="操作">
<template>
<div class="flex-c-a">

data：
data: {
baseForm: {
demoList: [
{
birthday: '2010-05-02',
name: '王小一',
age: 13,
address: '上海市普陀区金沙江路 1518 弄'
}, {
birthday: '2011-05-04',
name: '王小二',
age: 12,
address: '上海市普陀区金沙江路 1517 弄'
}, {
birthday: '2012-05-01',
name: '王小五',
age: 11,
address: '上海市普陀区金沙江路 1519 弄'
}, {
birthday: '2013-05-03',
age: 10,
name: '王小六',
address: '上海市普陀区金沙江路 1516 弄'
}
]
},
index: 0,
rules: {
name: [
{
required: true,
message: "请输入姓名",
trigger: "blur"
}
],
age: [
{
required: true, message: "请输入年龄", trigger: "blur" }
],
birthday: [
{
required: true, message: "请选择出生日期", trigger: "change" }
],
address: [
{
required: true, message: "请输入详细地址", trigger: "blur" }
],
}
}
method：
// 选中某一行修改或移除
selectItem(row, column, event) {
this.selectedFundRow = row
if (event.target.innerText == "删除") {
this.removeFundBtn(this.selectedFundRow)
}
},
// 删除指定行
removeFundBtn(params) {
this.baseForm.demoList = this.baseForm.demoList.filter((ele) => {
var flag = false
// 如果不一致，则保留该行
for (const key in params) {
if (ele[key] != params[key]) {
flag = true
break
}
}
return flag
})
// 如果全部删除后没有可以点击的一行了，需要加一行空行
if (!this.baseForm.demoList.length) {
this.addFund()
}
},
// 增加一个空行, 用于录入或显示第一行
addLine() {
const newLine = {
name: "",
age: "",
birthday: "",
address: ""
}
this.index++
this.baseForm.demoList.push(newLine)
},
// 提交
submit() {
this.$refs.baseForm.validate((valid) => {
if (valid) {
this.$confirm("您确定【提交】？", "提示", {
confirmButtonText: "确定",
cancelButtonText: "取消",
type: "warning"
}).then(() => {
console.log("校验通过")
})
}
})
}
使用的css：
.all {
width: 100%;
}
.flex-c-a {
display: flex;
align-items: center;
justify-content: space-around;
}
.margin-top-10 {
margin-top: 10px;
}
.base-form.el-form-item__content {
margin-left: 0;
}
.add-btn {
color: #4077F4;
}
.delete-btn {
color: #f56c6c;
}
完成
另：
1.“增加”的按钮可以统一提出来，放在el-form的最前面，因为每个增加按钮效果都是一样的，只是增加一个空行，而且add是独立绑定一个事件的，所以不会影响功能
2.鼠标悬浮在日期选择器上面的时候，会有一个黑色的会话框一样的东西，如果不需要这个效果，把时间选择器所在的el-form-item的悬浮显示效果show-overflow-tooltip去掉即可
代码截图如下：
去掉日期这栏的悬浮显示效果前：
去掉之后的页面效果：
