需求：验证表格同一行的最低限价不能超过销售定价
思路：先获取当前行table的index，然后在做大小比较
1.局部html
<el-table-column label="销售定价(元)" min-width="200px">
<template slot="header">
<span class="star">*</span>
<span class="star-name">销售定价(元)</span>
</template>
<template slot-scope="scope">
<el-form-item
:prop="'skuList.' + scope.$index + '.price'"
:rules="tableRules.price"
>
<el-input
size="small"
v-model.trim="scope.row.price"
@input="userInput"
placeholder="请输入销售定价"
/>
</el-form-item>
</template>
</el-table-column>
<el-table-column label="最低限价(元)" min-width="200px">
<template slot="header">
<span class="star">*</span>
<span class="star-name">最低限价(元)</span>
</template>
<template slot-scope="scope">
<el-form-item
:prop="'skuList.' + scope.$index + '.floorPrice'"
:rules="tableRules.floorPrice"
>
<el-input
size="small"
v-model.trim="scope.row.floorPrice"
@input="userInput"
placeholder="请输入最低限价"
/>
</el-form-item>
</template>
</el-table-column>
2.验证规则
const checkFloorPrice = (rule, value, callback) => {
let index = rule.field.split(".")[1];//获取当前行角标
if (!value) {
callback(new Error("请输入最低限价"));
} else if (value == Infinity || value > Math.pow(2, 31) - 1) {
callback(new Error("您填写的数字过长"));
} else if (!/^\d+(\.\d{1,2})?$/.test(value)) {
callback(new Error("请输入小数不超过两位的自然数"));
} else if (value >= this.tableForm.skuList[index].price) {//重点看这里
callback(new Error("最低限价不能超过销售定价"));
} else {
callback();
}
};
