请教个小程序方面的问题，我在开发者工具中用时，input中的值是取的到，为什么在手机上面取值不正常呢，要不取不到值，要不本次还是取的上一次的值,

wxml：

<view class="weui-search-bar" >

<view class="weui-search-bar__form">

<view class="weui-search-bar__box">

<input name="inputdata" class="weui-search-bar__input" placeholder="请输入查询内容"  bindblur="iearchInput" />

</view>

</view>

<button class="weui-search-bar__cancel-btn"  bindtap="so">

搜索

</button>

</view>

js中:

iearchInput:function(e){

var that=this;

that.data.sdata=e.detail.value;

},

so:function(){

var that = this;

var goodsearch = that.data.sdata;

if (goodsearch==''){

wx.showModal({

title: '错误',

content: that.data.sdata ,

showCancel: false,//是否显示取消按钮

confirmText: '确定',

confirmColor: "red",

success: function (res) {

if (res.confirm) {

}

}

})

return;

}

//跳转商品详情

wx.navigateTo({ url: '../shop/brand/brand?goodsname=' + goodsearch })

},
