整理使用 element-ui 开发时遇到的问题(包含“摘抄”其他开发人员开发遇到的问题 😁)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
| .clear-number-input.el-input::-webkit-outer-spin-button, .clear-number-input.el-input::-webkit-inner-spin-button { margin: 0; -webkit-appearance: none !important; } .clear-number-input.el-input input[type="number"]::-webkit-outer-spin-button, .clear-number-input.el-input input[type="number"]::-webkit-inner-spin-button { margin: 0; -webkit-appearance: none !important; } .clear-number-input.el-input { -moz-appearance: textfield; } .clear-number-input.el-input input[type="number"] { -moz-appearance: textfield; }
|
输入框仅支持数字
1 2 3 4 5
| <el-input v-model="form.num" placeholder="请输入数字" @keyup.native="form.num=form.num.replace(/[^\d.]/g,'')" ></el-input>
|
1 2 3 4 5 6 7 8 9 10
| <el-form inline @submit.native.prevent> <el-form-item label="订单号"> <el-input v-model="query.orderNo" :placeholder="输入订单号查询" clearable @keyup.enter.native="enterInput" /> </el-form-item> </el-form>
|
4、el-table固定列最后一行显示不完全、表头与内容错位
1 2 3 4 5 6 7 8
| .el-table__fixed-right { height:100% !important; }
// 全局设置 表头内容错位 .el-table--scrollable-y .el-table__body-wrapper { overflow-y: overlay !important; }
|
5、表单校验只其中一个字段
仅校验手机号码(如果需要多个参数,将参数改为数组形式即可。)
1 2 3 4 5
| this.$refs['form'].validateField('mobile', valid => { if (valid) { } })
|
6、el-table跨分页多选
1 2 3
| <el-table row-key="id"> <el-table-column type="selection" reserve-selection></el-table-column> </el-table>
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
| <el-table> <el-table-column label="名称"> <template> <el-input ref="inputRef" /> </template> </el-table-column> </el-table>
// 无效 this.$refs['inputRef'].focus() this.$refs['inputRef'][0].focus() this.$refs['inputRef'].$el.children[0].focus()
// 有效 <el-input id="inputRef" /> document.getElementById('inputRef').focus()
|
8、el-dialog 的 destroy-on-close 属性设置无效
1 2
| <el-dialog :visible.sync="visible" v-if="visible" destroy-on-close> </el-dialog>
