分步上传:当你需要提交两个及以上的文件,在一个文件成功后再提交另一个文件,并且最后需要提交所有文件的地址组成的数据
HTML:
<form id="uploadVideoForm" enctype="multipart/form-data">
<label for="group-name">组别名称:</label>
<input type="text" name="group-name"/>
<label for="head-name">负责人:</label>
<input type="text" name="head-name"/>
<div class="check-video">
<span>视频简介:</span>
<video id="myVideo" autoPlay width="300"></video>
<input type="file" accept="video/*" class='intro-video' name="file"/>
</div>
<div class="martop">
<div class="group-intros">
<p>负责人简介</p>
<input type="text" name="group-head"/>
<p>组别介绍</p>
<input type="text" name="group-intro"/>
<p>组内成员</p>
<input type="text" name="group-people"/>
</div>
</div>
<button class="save">添加</button>
<button class="update_data">确定修改</button>
<span class="cancle">清空</span>
</form>
<form id="uploadImgForm" enctype="multipart/form-data">
<label for="video-name">负责人照片:</label>
<div id="box">
<img id="imgshow" src="" alt=""/>
</div>
<div id="pox">
<input id="filed" type="file" accept="image/*" name="file"/>
</div>
<button class="update_group"></button>
</form>
JS:在点击提交后,执行文件的提交并阻止默认提交,提交成功后或者第一个文件为空时,使用$(element).trigger('click')触发另一个表单的点击(提交)事件并阻止默认提交,成功后使用Ajax发送结果的json数据。
