我不知道为什么在桌面上工作,但在手机上,它显示为这样 2 hrs + 2 oz

它似乎加载了默认值 2 。即使Chrome模拟器显示错误 only 移动视图。这是一个 float 在数据库中。

在数据库中查看其值

更新

public function settingsUpdate($id){
    $baby     = Baby::where('uuid',$id)->first();   
    if($baby){

        $baby->name            = Request::get('name','');
        $baby->phone           = Request::get('phone','');
        $baby->email           = Request::get('email','');
        $baby->babyName        = Request::get('babyName','');
        $baby->babyDob         = Request::get('babyDob','').' '.Request::get('babyHob','').':00';
        $baby->adminCode       = Request::get('adminCode','');
        $baby->readOnlyCode    = Request::get('readOnlyCode','');
        $baby->feedingInterval = (float) Request::get('feedingInterval',''); <<<----------  ✨
        $baby->feedingAmount   = (float) Request::get('feedingAmount',''); <<<----------  ✨
        $baby->displayMode     = Request::get('displayMode','');

        $baby->save();

        return Redirect::to('/baby/'.$baby->uuid.'?code='.$baby->adminCode);

    } else {
        return Redirect::to('/');
    }
}

HTML/视图

<div class="form-group">
    <div class="col-xs-6">
        <label for="feedingInterval"><h5>Feeding Interval <small class="helpText">(hours)</small></h5></label>

        <select class="form-control" id="feedingInterval" name="feedingInterval">
            <option value="2">2 hrs </option>
            <option value="2.5">2.5 hrs </option>
            <option value="3">3 hrs </option>
            <option value="3.5">3.5 hrs </option>
            <option value="4">4 hrs </option>
            <option value="4.5">4.5 hrs </option>
            <option value="5">5 hrs </option>
            <option value="5.5">5.5 hrs </option>
            <option value="6">6 hrs </option>
        </select>

    </div>


    <div class="col-xs-6">
        <label for="feedingAmount"><h5>Feeding Amount <small class="helpText">(ounces)</small></h5></label>

        <select class="form-control" id="feedingAmount" name="feedingAmount">
            <option value="2">2 oz </option>
            <option value="2.5">2.5 oz </option>
            <option value="3">3 oz </option>
            <option value="3.5">3.5 oz </option>
            <option value="4">4 oz </option>
            <option value="4.5">4.5 oz </option>
            <option value="5">5 oz </option>
            <option value="5.5">5.5 oz </option>
            <option value="6">6 oz </option>
        </select>
        
    </div>



</div>

得到

    $('#feedingInterval').val(`{{$baby->feedingInterval}}`.toString());
    $('#feedingAmount').val(`{{$baby->feedingAmount}}`.toString());
