<form class="form-horizontal form-bordered form-row-strippe" enctype="multipart/form-data" method="post" name="fileinfo" id="fileinfo" data-toggle="validator"> <div class="modal-body"> <div class="form-horizontal"> <div class="control-group"> <label class="control-label" style="width: 125px;"> 审批项目名称：</label> <div class="controls" style="margin-left: 0px;"> <input type="text" id="id" name="id" style="display:none;" value="$id$" /> <input type="text" id="projectname" name="projectname" class="m-wrap large" value="$projectname$" /> </div> </div> <div class="control-group"> <label class="control-label" style="width: 125px;"> 审批项目说明：</label> <div class="controls" style="margin-left: 0px;"> <input class="m-wrap large" type="text" id="projectinfo" name="projectinfo" value="$projectinfo$" /> </div> </div> <div class="control-group"> <label class="control-label" style="width: 125px;"> 审批项目文件：</label> <div class="controls" style="margin-left: 0px;"> <input type="file" id="filepath" name="filepath" style="display:none" onchange="changetext()" /> <input class="m-wrap" type="text" id="pathfile" name="pathfile" readonly="readonly" value="$filepath$" /> <input class="btn green" type="button" value="选择文件" id="uploadpath" /> </div> </div> </div> </div> <div class="modal-footer bg-info"> <input class="btn blue" type="button" id="btnsubmit" value="提交" onclick="update()" data-dismiss="modal" /> <button type="button" class="btn green" data-dismiss="modal"> 取消</button> </div> </form>
