Web前端开发交互过程中需各种转换的函数封装

<script>

    //处理各种异常文本

    function dispose(flag, str) {

        var result = ”

        switch (flag) {

            case 1:

                result = str ? str : ”

                result = str ? str : 0

                break

            case 3:

                result = str ? str : ‘匿名’

                break

            case 4:

                result = str ? str : ‘未知地区’

                break

            case 5:

                result = str ? str : ‘未知’

                break

        }

        return result

    }

    //作品状态

    function getWorkStus(type) {

        var value = ”

        if (type == 0) {

            value = ‘未售’

        } else if (type == 1) {

            if (id == typeArr[i].id) {

                value = typeArr[i].name

            }

        }

        return value

    }

    //截取字符串

    function omit1(str, num) {

        if (str) {

            if (str.length > num) {

                str = str.substring(0, num) + ‘…’
