关于vxe-select得filter-method 自定义方法得使用，忽略大小写匹配

 vxe-select使用模糊匹配时，filter-method自定义匹配方法，模糊忽略大小写进行匹配数据

<vxe-select v-model="marketingId":options="marketingOptions"transfer clearable placeholder="市场"filterable :filter-method="customFilter"></vxe-select>getMarketingOptions () {xxxxxx().then(res => {if (res.code === 200) {this.marketingOptions = []if (res.data.length > 0) {res.data.map(item => {this.marketingOptions.push({value: item.code,label: item.name})})}} else {this.$message.error(res.msg)
this.marketingOptions = []}}).catch(err => {this.$message.error(err.msg)
this.marketingOptions = []})},// 模糊匹配  忽略大小写匹配数据customFilter ({searchValue, option, group}) {if (option.label.toLowerCase().indexOf(searchValue.toLowerCase()) > -1) {return true} else {return false}},
