步骤:
1. 点击行时触发复选框的选择或取消
2.点击复选框时触发相应行的变化(问题关键在怎么获取复选框选取的行)
需求:对el-table 选中行时复选框也被选中,选中复选框时触发行的相应变化(拢共分两步)
步骤:第一步:点击行时触发复选框的选择或取消;
第二步:点击复选框时触发相应行的变化(问题关键在怎么获取复选框选取的行)
1. 点击行时触发复选框的选择或取消// <template>
<el-table
class="right-panel-table"
:data="tableData"
@selection-change="(val) => handleSelectionChange(val,'ischeckboxTick')"
ref="multipleTable"
v-loading="planLoading"
@cell-mouse-enter="handleMouseEnter"
@cell-mouse-leave="handleMouseOut"
@row-click="(row,column,event) => handleRowClick(row,column,event,'onclumn')"
highlight-current-row
>
// <script> 添加row-click方法,点击列表行时触发
handleRowClick(row,column,event, onclumn){
if(onclumn === 'onclumn') {
this.isonClunm = true;
}
row.flag = !row.flag;
this.$refs.multipleTable.toggleRowSelection(row, row.flag);
if(row.flag) {
this.selectSatitleLatLon(row);
} else {
this.unselectSatitleLatLon(row);
}
}
添加完以上代码后,点击行,相应行前面的复选框会跟着选中或取消
2.点击复选框时触发相应行的变化(问题关键在怎么获取复选框选取的行)当点击列表行时,先触发row-click事件,然后再触发 selection-change事件,点击复选框时只触发selection-change事件,想要判断出点击复选框时触发的是哪一行时,则需要对上一次选中的列表项和这次选中的列表项对比
// template部分同上
// <script>
handleSelectionChange(val, checkFlag) {
let that = this;
if(checkFlag === 'ischeckboxTick') {
that.ischeckboxTick = true
}
// 获取当前增加的或者减少的那条数据
let n = {};
let currentVal = [];
val.forEach(item => {
currentVal.push(item);
})
if(val.length > that.multipleSelection.length) {
// 增加时比之前不一样的某个值
n = (val.filter(item => !that.multipleSelection.includes(item)))[0];
} else {
// 减少时与之前不一样的值
let oldSelect = [];
that.multipleSelection.forEach(item => {
oldSelect.push(item)
})
if(val.length === 0) {
n = that.multipleSelection[0];
} else {
that.multipleSelection.forEach((item, index) => {
let delIndex = 0;
currentVal.forEach((item1, index1) => {
if(item.sname === item1.sname && item.startTime === item1.startTime && item.endTime === item1.endTime) {
delIndex = index;
currentVal.splice(index1, 1);
oldSelect.splice(delIndex, 1, '');
}
})
})
oldSelect.forEach(item => {
if(item !== '') {
n = item
}
})
}
}
that.multipleSelection = val; // 选中的所有项
that.isonClunm = false;
that.ischeckboxTick = false;
},
