使用: <Table border ref="selection" :columns="columns" :data="listData" :loading="false"></Table> 複製代碼 設置: columns: [ { type: 'selection', width: 60, align: 'center' }, { title: '排序值', key: 'sortOrder', align: 'center' }, { title: '品牌鏈接', key: 'siteUrl', align: 'center', render: (h, params) => { return h('a', { attrs: { href: params.row.siteUrl, }, class:{ siteUrl: true, } }, params.row.siteUrl); } }, { title: '操作', align: 'center', render: (h, params) => { let row = params.row; return h('div', [ h('Button', { props: { type: 'ghost', size: 'small' }, style: { marginRight: '5px' }, on: { click: () => { this.toCheckDetails(row.id); } } }, '查看'), h('Button', { props: { type: 'ghost', size: 'small' }, style: { marginRight: '5px' }, on: { click: () => { this.toEdit(row.id); } } }, '編輯') ]); } } ] 複製代碼 屬性大全: render: (h, params) {//params是一個對象,包含 row、column 和index,分別指當前行數據,當前列數據,當前行索引 return h('div', { props: { // Component props msg: 'hi', }, attrs: { // normal HTML attributes id: 'foo' }, domProps: { // DOM props innerHTML: 'bar' }, on: { // Event handlers click: this.clickHandler }, // For components only. Allows you to listen to native events, rather than events emitted from the component using vm.$emit. nativeOn: { click: this.nativeClickHandler }, class: { // class is a special module, same API as `v-bind:class` foo: true, bar: false }, style: { // style is also same as `v-bind:style` color: 'red', fontSize: '14px' }, // other special top-level properties key: 'key', ref: 'ref', // assign the `ref` is used on elements/components with v-for refInFor: true, slot: 'slot' }) } 複製代碼 table組件input值的綁定和獲取: 1、render函數中不能直接使用v-model; 2、解決辦法: render: (h, {row}) => { return h('Input', { props: { clearable: true, placeholder: '標籤編號', value: row.tagCode, }, on: { input: (val) => { row.tagCode = val; } } }); }

iview 的render函數就是vue的render函數
iview常用在表格裏面自定義內容
render函數常用的配置
h就是createdElement的簡寫
3個參數如下:
h("元素名稱或組件名稱", {
domProps: { // 原生dom元素的一些屬性
value: 1,
type: 'number',
min: 1,
innerHTML:’‘
},
props:{ // 傳給組件數據 比喻iview Button的type,size 等等
type:'text',
size:'small'
},
class:{ // 類
btn:true//
},
attrs:{ // html屬性,class
id:'box'
class:'brn2'
},
style:{ // 內聯樣式
},
slot:'slotName', // 組件的插槽
on:{ // 事件 包括組件的自定義事件
click:()=>{
},
'on-change':()=>{
},
},
nativeOn:{ // 類似vue的.native修飾符,自定義組件常用
click:()=>{
}
}
}

h的第二個參數支持數組的形式,數組裏面可以是多個h渲染出來的元素對象或字符串
eg:
1,渲染多個組件
{
title: '操作',
width: 150,
render: (h, { row, index }) => {
let btn = h('i-switch', {
props: {
value: row.join_status === 1 ? true : false,
size: 'large',
loading: row.loading
},
on: {
'on-change': (val) => {
this.tabData[index].loading = true
if (!val) {
this.$Modal.confirm({
title: '你確定要禁用該加盟商嗎?',
content: '<p>禁用將會導致該加盟商下所有人員無法登陸CRM系統</p>',
onOk: () => {
this.changeChannelStatus(row.id)
},
onCancel: () => {
this.tabData[index].loading = false
}
});
return
}
this.changeChannelStatus(row.id)
}
}
}, [
h('span', {
slot: 'open',
domProps: {
innerHTML: 'ON'
}
}),
h('span', {
slot: 'close',
domProps: {
innerHTML: 'OFF'
}
})
]
)
let edit = h('a', {
style: {
'margin-right': '15px',
},
on: {
click: () => {
this.$router.push({ name: 'addJoiner', query: { ...row, tit: '編輯加盟商' } })
}
}
}, '編輯')
return h('div', [edit, btn])
}

效果圖:
switch 異步時loading狀態
2,渲染自定義組件
{
title: '狀態',
render: (h, { row }) => {
return h(myTag, {
props: {
color: row.join_status === 1 ? '#52C41A' : 'red'
},
class: {
'hahah': true
},
nativeOn: { //事件
click: () => {
alert(1)
}
}
}, row.join_status === 1 ? '正常' : '解約')
}
},

值得注意的是配置的參數vlaue支持變量。
怎麼綁定v-model?
這個問題vue官方說了:是沒法綁定的,只能自己實現
實現也不難
eg:
{
title: '價格',
key: 'name',
render: (h, { row, index }) => {
let input = h('input', {
domProps: {
value: row.price,
type: 'number',
min: 1
},
style: {
width: '200px',
display: 'inline-block',
height: '32px',
'line-height': 1.5,
},
on: {
change: (event) => { // 實現綁定數據
let val = event.target.value
this.tabData[index].price = val
}
}
})
let arr = [input]
let tip = h('span', {
style: {
color: 'red',
marginLeft: '10px'
}
}, '必填,最多保留兩位小數')
if (row.tip) {
arr.push(tip)
}
return h('div', arr)
}
}
