ios Safari浏览器不支持 js 复制字符串

ios Safari浏览器不支持 js 复制字符串

本来设计成:点击"复制"按钮,可以复制订单号到剪切板的.

可以发现在 ios Safari 浏览器中不起作用.

后来在http://stackoverflow.com/ 查到

 参考:http://stackoverflow.com/questions/34045777/copy-to-clipboard-using-javascript-in-ios

解决方法:

判断操作系统类型,如果是 ios 则不显示"复制"按钮(因为显示了,也无用)

(1)判断操作系统类型

ClientOsInfo info =SpringMVCUtil.getMobileOsInfo(request);
        model.addAttribute("ostype",info.getOsType());

 osType的取值为"Ios","Android","WINDOWS PHONE"

public static final String OSTYPE_ANDROID="Android";
    public static final String OSTYPE_IOS="Ios";
    public static final String OSTYPE_WP="WINDOWS PHONE";
    /***
     * 黑莓
     */
    public static final String OSTYPE_BLACKBERRY="BLACKBERRY";

 (2)前端通过 freeMark 判断:

<#if !(ostype??)|| ostype!='Ios'>
        <div id="copy_order"  >复制</div>
        <div id="copy_money"  >复制</div>
    </#if>

 SpringMVCUtil.getMobileOsInfo

方法实现如下

/**
     * 判断手机的操作系统 IOS/android/windows phone/BlackBerry
     *
     * @param UA
     * @return
     */
    public static ClientOsInfo getMobilOS(String UA) {
