mixin全局混入

import Vue from 'vue';

Vue.mixin({
    data() {
        return {
            uploading: ''
        }
    },
    methods: {
        // 表格行背景色
        tableRowClassName(row) {
            // 表格行背景色
            if (row.rowIndex % 2 == 1) {
                return "warning-row";
            } else {
                return "success-row";
            }
        },

        /**
         * 表单重置
         * @param {string} formName 
         */
        resetForm(formName) {
            if (formName == 'selectForm') {
                this.selectForm = this.$options.data().selectForm;
                this.pageInfo.pageNum = 1;
                this.getTableData();
            } else if (formName == 'editorForm') {
                this.editorForm = this.$options.data().editorForm;
            }
        },

        // 头部表单查询
        formSelect() {
            this.pageInfo.pageNum = 1;
            this.getTableData();
        },

     
        // 自定义序号
        indexMethod(index) {
            return (this.pageInfo.pageNum - 1) * this.pageInfo.pageSize + index + 1;
        },


    },
    created() {}
})

需要用到mixin的页面引入该文件直接当本页面属性、或方法调用即可。
