vue项目使用label标签for到一个input(文件上传)上label里面是一个组件点击组件并没有调用input上传自己又写了一个label里面随便打了几个字点击后可以调用input问题出在哪？下面这样无法调用<file-uploadid="headUpload":target="uploadUrl"action="POST"v-on:progress="progress"v-on:start="startUpload"v-on:finish="finishUpload"class="uploadBox"></file-upload><view-boxref="viewBox"><labelfor="headUpload"><groupgutter="0"style="display:block;overflow:hidden"><cellvalue="修改头像"link="#headUpload"><imgslot="icon"width="50"style="display:block;margin-right:5px;border-radius:50%":src="user.head"></cell></group></label>...如果是下面这样则可以调用<file-uploadid="headUpload":target="uploadUrl"action="POST"v-on:progress="progress"v-on:start="startUpload"v-on:finish="finishUpload"class="uploadBox"></file-upload><view-boxref="viewBox"><labelfor="headUpload">12313131313123132</label><groupgutter="0"style="display:block;overflow:hidden"><cellvalue="修改头像"link="#headUpload"><imgslot="icon"width="50"style="display:block;margin-right:5px;border-radius:50%":src="user.head"></cell></group>...
