最近在做webapp搜索功能时，用到两个input同时存在时，轻点input聚焦时，ios手机软键盘弹起又失效，一直在寻找合理的解决办法，现在最简单的总结回顾:

<一>bug显示

<二> 最终测试通过的修改方案

1. 安卓保持不动，原生input当点击的时候可以自动聚焦;

2. ios单个input的也是正常的，就是两个input在一起失效；

3. 当两个input在一起的时候，每一个input外面包裹一层div，里面有一个span标签。

测试代码如下:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        div {
            width: 120px;
            height:24px;
            border: 1px solid #ccc;
            position: relative;
        }
        div span {
            display: block;
            width: 120px;
            height:24px;
            position: absolute;
            top:0;
            left:0;
        }
    </style>
</head>
<body>
    <div>
        <input type="text" >
        <span ></span>
    </div>
</body>
<script type="text/javascript">
    iosContainer.addEventListener("click",function(e){
        iosInput.focus();
    });
</script>
</html>

备注: 我最终的代码结构,在ios手机和安卓手机表现度正常了

ios事件执行代码

componentDidMount:function(){
        if(/(APPLEWEBKIT|Safari|Android)/i.test(this._ua)) {
            $('.cmr-sr_notice').css({'position':'fixed'});
        }else{
            iosContainer_01.addEventListener("click",function(e){
                iosInput_01.focus();
            });
            iosContainer_02.addEventListener("click",function(e){
                iosInput_02.focus();
            });
        }
    },

布局结构

timelyNotice:function(){
        var _this = this,
            iosInput_01='',
            iosInput_02='';
            // ios 通过外部点击事件来取货焦点，安卓还保持原生的不动
        if(/(APPLEWEBKIT|Safari|Android)/i.test(this._ua)) {
            iosInput_01 = (
                <input type='text' placeholder='书名' maxLength='100'
                    className='co-font-biggest cmr-sr_notice-input'
                    onChange={_this.valChange.bind(_this,1)}
                    value={_this.state.valBookname}
                    onBlur={_this.inputBlur}
                    ref='valBookname'
                />
            );
            iosInput_02 = (
                <input type='text' placeholder='作者' maxLength='100'
                    className='co-font-biggest cmr-sr_notice-input'
                    onChange={_this.valChange.bind(_this,2)}
                    onBlur={_this.inputBlur}
                    value={_this.state.valAuhtorname}
                    ref='valAuhtorname'
                />
            )
        }else {
            iosInput_01 = (
                <div style={{position:'relative'}}>

                        />
