指定字段要截断指定长度,超过的用...代替

java 代码

 /**
     * 字符串过长,则使用"…"替换
     *
     * @param input
     * @param length 显示的字符的个数
     * @return
     */
    public static String omitTooLongString(String input, int length) {
        if (input == null || input.trim().equals(Constant.EMPTY)) {
            return input;
        }
        int len = input.length();

        if (len <= length) {
            return input;
        } else {
            input = input.substring(0, length);
            input += Constant.ENGLISH_ELLIPSIS;
        }
        return input;
    }

 调用:

this.orgDisplayName = StringUtil.omitTooLongString(orgFullName,
                ORG_FULL_NAME_MAX_LENGTH);

JavaScript 代码

var omitTooLongString = function (input, length) {
    if (!input) {
        return input;
    }
    var len = input.length;
    if (len <= length) {
        return input;
    } else {
        input = input.substring(0, length);
        input += "...";
    }
    return input;
};

 调用:

omitTooLongString(orgFullName_val, 14)
