1.dom中代码，监听所选日期值的变化，并把需要比较的时间字段作为参数传到监听方法中，

<el-form-item label="起始日期" prop="startTime"><el-date-picker clearable size="small":disabled="isDisable"v-model="form.startTime"type="date"value-format="yyyy-MM-dd"@change="checkTime(form.startTime,form.expirationTime,form.signingTime,'start')":placeholder="isDisable? '':'选择起始日期'"></el-date-picker></el-form-item><el-form-item label="终止日期" prop="expirationTime"><el-date-picker clearable size="small":disabled="isDisable"v-model="form.expirationTime"type="date"value-format="yyyy-MM-dd"@change="checkTime(form.startTime,form.expirationTime,form.signingTime,'expiration')":placeholder="isDisable? '':'选择终止日期'"></el-date-picker></el-form-item><el-form-item label="签订时间" prop="signingTime"><el-date-picker clearable size="small":disabled="isDisable"v-model="form.signingTime"type="date"value-format="yyyy-MM-dd"@change="checkTime(form.startTime,form.expirationTime,form.signingTime,'signing')":placeholder="isDisable? '':'选择签订时间'"></el-date-picker></el-form-item>

2.时间比较逻辑处理

 //时间判断checkTime(startTime, expirationTime,signingTime, type) {/* if (startTime == '' || startTime == null || startTime == undefined) {return;}if (expirationTime == '' || expirationTime == null || expirationTime == undefined) {return;}if (signingTime == '' || signingTime == null || signingTime == undefined) {return;}*/if (startTime > expirationTime) {this.$modal.msgWarning("开始时间应小于终止时间!");if (type == 'start') {this.$set(this.form, 'startTime', '');} else if (type == 'expiration') {this.$set(this.form, 'expirationTime', '');}}if (startTime < signingTime) {this.$modal.msgWarning("开始时间应大于或等于签订时间!");if (type == 'start') {this.$set(this.form, 'startTime', '');}else if (type == 'signing') {this.$set(this.form, 'signingTime', '');}}},

二.当比较的是form表单中数组中循环的两个时间时，用以下方法
1.dom中监听日期值的变化 @change=“checkTime()”

 //本次读数时间必须大于上次读数时间checkTime() {this.form.readings.forEach(item => {if (item.readingTime < item.scdssj) {this.$modal.msgError("本次读数时间应大于上次读数时间!");item.readingTime = ''; // 清空本次读数所选日期}});},
