本文主要介绍了vue+elementui通用弹窗的实现(新增+编辑),分享给大家,具体如下:
组件模板
<el-dialog :title=\"title\" :visible.sync=\"dialogShow\" :close-on-click-modal=\"false\"> <div class=\"ym-common-dialog\" :class=\"customClass\"> <div v-for=\"(col,index) in cols\"> <span><em v-if=\"!!col.isRequire\">*</em>{{col.name}}</span> <template v-if=\"col.type === \'text\'\"> <div>{{submitData[col.key]}}</div> </template> <template v-if=\"col.type === \'input\'\"> <input type=\"text\" v-model=\"submitData[col.key]\" :placeholder=\"\'请输入\' + col.name\"> </template> <template v-if=\"col.type === \'radio\'\"> <div class=\"flexX\"> <el-radio v-for=\"radio in col.data\" v-model=\"submitData[col.key]\" :label=\"radio.label\">{{radio.name}}</el-radio> </div> </template> <template v-if=\"col.type === \'select\'\"> <el-select v-model=\"submitData[col.key]\" placeholder=\"请选择\"> <el-option v-for=\"option in col.data\" :key=\"option.value\" :label=\"option.label\" :value=\"option.value\"> </el-option> </el-select> </template> </div> </div> <span slot=\"footer\" class=\"dialog-footer\"> <el-button @click=\"dialogShow = false\">取 消</el-button> <el-button type=\"primary\" @click=\"confirm\">确 定</el-button> </span> </el-dialog>
弹窗的内容根据传入的数据去渲染,数据格式如下
cols: [{ name: \'输入框\', key: \'ccc\', // 提交时对应的字段 type: \'input\', // 类型 isRequire: true // 是否必填 }, { name: \'单选框\', key: \'aaa\', type: \'radio\', data: [{ label: \'1\', name: \'长城\' }, { label: \'2\', name: \'长安\' }], isRequire: true }, { name: \'下拉框\', key: \'bbb\', type: \'select\', data: [{ value: \'选项1\', label: \'黄金糕\' }, { value: \'选项2\', label: \'双皮奶\' }], isRequire: true }],
组件data和props
data() { return { submitData: {}, // 提交数据集合 dialogShow: false } }, props: { // 弹窗显示/隐藏 dialogVisible: { type: Number, default: 0 }, // 弹窗Title title: String, // 自定义样式 customClass: String, // 数据列 cols: { type: Array, default: () => [] }, // 编辑时传入初始值 data: { type: Object, default: () => {} } },
组件数据的监听
watch: { dialogVisible(val) { if (val > 0) { this.dialogShow = true } }, data: { handler(val) { this.submitData = val }, immediate: true }, submitData: { // 应对 切换单选框隐藏其他元素的问题 // 父组件监听到单选框的值变化时,修改cols的值,即可实现元素的隐藏与显示 handler() { this.$emit(\'change\', this.submitData) }, deep: true } }
数据提交以及验证
confirm() { // 验证必填项 let isMust = this.cols.filter(item => item.isRequire).map(item => item.key) Object.keys(this.submitData).forEach(key => { let index = isMust.indexOf(key) if ((index > -1) && this.submitData[key] !== \'\' && !!this.submitData[key]) { isMust.splice(index, 1) } }) if (isMust.length > 0) { showDefaultTips(\'请注意必填项!\', \'\', 3) return } this.$emit(\'complete\', this.submitData) this.dialogShow = false }
