问题描述
问 题
我的代码中有一个删除全部按钮,然后有一个@click，不清楚nowIndex是如何传递到模态框的，还是bootstrap自带的模态框有接受参数功能？：
<tr class="text-right" v-show="myData.length!=0">
<td colspan="4"><button type="button" class="btn btn-danger" data-toggle="modal" data-target="#layer" @click="nowIndex=-2">删除全部</button></td>
</tr>
然后一个模态框：
<div role="dialog" class="modal fade" id="layer" data-index="nowIndex">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" ><span>×</span></button>
<h4 class="modal-title">确认删除吗？</h4>
</div>
<div class="modal-body text-right">
<button class="btn btn-primary btn-sm" name="button" data-dismiss="modal">取消</button>
<button class="btn btn-danger btn-sm" name="button" data-dismiss="modal" @click="delMsg(nowIndex)">确认</button>
</div>
</div>
