在项目中发现使用el-select时写的比较多重复代码，还有就是同一个页面使用el-select会出现label值会显示value值，
el-select组件化：
<template> <el-select :class="obj&&keyword[keywordAttr.label]? 'selected': ''" :value="keyword" :placeholder="obj && keyword[keywordAttr.label]? keyword[keywordAttr.label]: placeholder" filterable :clearable="clear" remote :multiple="multiple" :loading="selectLoading" :reserve-keyword="reserve" :remote-method="remoteMethod" :style="{width: width}" :disabled="disabled" :value-key="keywordAttr.id" @change="changeSelect" @clear="handleClear" @blur="handleBlur" @focus="handleFocus" @visible-change="handlerVisible" > <el-option v-for="item in keywordOptions" :key="item[keywordAttr.id]" :label="item[keywordAttr.label]" :value="obj? item: item[keywordAttr.value]" :disabled="item.disabled" > <slot :item="item"/> </el-option> </el-select> </template> <script> export default { name: 'SelectRemote', props: { value: { type: [String, Object], default: '' }, reserve: { type: Boolean, default: true }, clear: { type: Boolean, default: false }, disabled: { type: Boolean, default: false }, multiple: { type: Boolean, default: false }, selectLoading: { type: Boolean, default: false }, width: { type: String, default: '100%' }, keywordOptions: { type: Array, default: function() { return [] } }, keywordAttr: { type: Object, required: true, default: function() { return { id: '', label: '', value: '' } } }, obj: { type: Boolean, default: false }, placeholder: { type: String, default: function() { return '请输入关键词' } } }, data() { return { keyword: this.value } }, watch: { value(newVal) { this.keyword = newVal } }, methods: { remoteMethod(query) { this.$emit('remoteMethod', query) }, changeSelect(item) { this.$emit('changeSelect', item) }, handleClear() { this.$emit('clear') }, handleBlur() { this.$emit('blur') }, handleFocus() { this.$emit('focus') }, handlerVisible() { this.$emit('visible-change') } } } </script> <style lang="scss" scoped> .selected ::-webkit-input-placeholder{ color: #606266 !important; } </style>
主要是使用了placeholder来显示；
在父组件中:
<SeletcRemote v-model="nodeOperate.saleEmp" :keyword-attr="nodeObjPerson" :keyword-options="empOptions" :clear="true" :obj="true" :select-loading="selectLoading" @remoteMethod="remoteMethod" @changeSelect="handleProductChange($event, nodeOperate, 'saleEmp')" />
nodeObjPerson: { id: 'id', label: 'empName' }
handleProductChange(val, row, field) { this.$set(row, field, val) }
可以在单选的的状态下完美解决了label显示值；
在多选状态下如何显示？
multipletrue时，暂时无法解决；只是使用了另一个组件：vue-multiselect
