<view>

<form bindsubmit=“formSubmit”>

<view class=‘back’>

<view class=‘back_title’>公司地址</view><text class=‘star’>*</text>

<textarea placeholder=‘请输入公司地址’ maxlength=‘104’ class=‘back_input’ value=’{{value}}’ bindblur=“save”></textarea>

</view>

<button class=‘newsbtn’ form-type=‘submit’ disabled=’{{!value||noable}}’>保存</button>
