1、在组件上写上自定义事件的名称
v-el-table-tableLazy="tableLazy" 或 v-el-select-selectLazy="selectLazy" 2、在export default 内上自定义事件指令 directives: { "el-select-selectLazy": { bind(el, binding) { let SELECT_DOM = el.querySelector( ".el-select-dropdown .el-select-dropdown__wrap" ) SELECT_DOM.addEventListener("scroll", function () { let condition = this.scrollHeight - this.scrollTop <= this.clientHeight if (condition) { binding.value() } }) }, }, "el-table-tableLazy": { bind(el, binding) { let SELECT_DOM = el.querySelector( ".el-table__body-wrapper" ) SELECT_DOM.addEventListener("scroll", function () { let condition = this.scrollHeight - this.scrollTop <= this.clientHeight if (condition) { binding.value() } }) }, }, }, 3、在methods里面写上事件调用 tableLazy() { if (this.total == this.historyList.length) { this.historyListSum = false } else { this.page.currentPage++ this.getHistoryList() } },// 下拉框懒加载 selectLazy() { if (this.equipmentTotal == this.equipmentList.length) { return } else { this.equipmentPage.currentPage++ this.getListData() } },
