移动端 -webkit-user-select:text; ios10 bug 解决方案

移动端一般body的css、会设置 作用就不解释了；

?

body{ height:100%;min-height:100%; font-family: "微软雅黑",'Helvetica Neue',Helvetica,tahoma,arial,sans-serif; text-rendering:optimizeLegibility;-webkit-font-smoothing:antialiased; line-height: 1; font-size:14px;-webkit-touch-callout:none;-webkit-user-select:none;}

 

我们看看下面的代码

<div  style=" margin-top: 100px; background: #888;">
    <p  style="-webkit-user-select:text !important;line-height: 30px; padding: 10px;  text-align: center; ">1移动端 suface复制文本测试啊  父类没有 -webkit-user-select:text;;</p>
 
</div>

　　

 

以上代码 手机iphone5s 的ios9 没问题，可是换个iphone7 ios10的 出现 无法选中；

后来去掉所有css 样式  js 发现

解决方案

1 去掉body的 -webkit-touch-callout:none;但是不切实际 

2 其他能选文本复制的地方 （下面的）  的文本先手动选择一下。然后再去选择你要选的就可以了；不实际；

3后来发现必须 父元素加个-webkit-user-select:text;才有效，单独子元素即使加-webkit-user-select:text!important也无效

<div  style=" margin-top: 200px; background: #888;-webkit-user-select:text;;">
    <p  style="-webkit-user-select:text !important;line-height: 30px; padding: 10px;  text-align: center; "> 2移动端 suface  复制文本测试啊 父类 加了-webkit-user-select:text;;</p>
</div>

　　

 

工作中的小问题，记录一下；

另外，发现 手机 uc  弹窗出来的元素无法复制，

例如 这段 添加到一个 Dialog 里面的innerHTML,  却无法复制，

<div  style=" margin-top: 200px; background: #888;-webkit-user-select:text;;">
    <p  style="-webkit-user-select:text !important;line-height: 30px; padding: 10px;  text-align: center; "> 2移动端 suface  复制文本测试啊 父类 加了-webkit-user-select:text;;</p>
</div>

之后发现动态添加的uc 浏览器  copy无效，需要设置 diologClass 的class，  .cancopy div{-webkit-user-select:text;}

<div class="diologClass cancopy"><div   style=" margin-top: 200px; background: #888;-webkit-user-select:text;;">
    <p  style="-webkit-user-select:text !important;line-height: 30px; padding: 10px;  text-align: center; "> 2移动端 suface  复制文本测试啊 父类 加了-webkit-user-select:text;;</p>
</div></div>

 

移动端复制 解决方案 ，兼容性还行，参考 clipboard官网 https://clipboardjs.com 上，核心模块 ，下面 copy 函数来自 clipboard；
