今天写表单提交的时候需要增加一个确认提示，所以没有使用submit按钮提交，改用jq的submit()，然后问题了
<form class="form-horizontal m-t" method="post" action="@Url.Action("Edit")" id="form"> <div class="row"> <div class="col-sm-12"> <div class="ibox float-e-margins"> <div class="ibox-title"> <h5>添加</h5> </div> <div class="ibox-content"> <div class="form-group"> <label class="col-sm-3 control-label">开始时间：</label> <div class="col-sm-8"> <span> @(Model.annualRate_beginDate?.ToString("yyyy-MM-dd")) </span> </div> </div> <div class="form-group"> <label class="col-sm-3 control-label">结束时间：</label> <div class="col-sm-8"> <input type="text" class="form-control" name="annualRate_endDate" id="annualRate_endDate" onclick="laydate({ istime: false, format: "YYYY-MM-DD" })" value="@Model.annualRate_endDate.ToString("yyyy-MM-dd")" required> </div> </div> <div class="form-group"> <label class="col-sm-3 control-label">年利息%：</label> <div class="col-sm-8"> <input type="number" step="0.01" class="form-control" id="annualRate_rate" name="annualRate_rate" value="@Model.annualRate_rate.ToString("#0.00")" required> </div> </div> <div class="form-group"> <div class="col-sm-4 col-sm-offset-2"> <button class="btn btn-lg btn-primary" id="submit_btn" type="button"> 提交 </button> <a class="btn btn-lg btn-white" href="@Url.Action(" rel="external nofollow" Index")"> 取消 </a> </div> </div> </div> </div> </div> </div> </form>
<script type="text/javascript"> $(function () { $("#submit").click(function () { var start = "@(Model.annualRate_beginDate?.ToString("yyyy-MM-dd"))"; var end = $("#annualRate_endDate").val(); var val = $("#annualRate_rate").val(); layer.confirm("请确认所填写的信息是否正确？<br/>开始时间：" + start + "<br/>结束时间：" + end + "<br/>年利率:" + val, { icon: 3, title: "提示" }, function (index) { $("#form").submit(); layer.close(index); }); }); }) </script>
点击提交按钮出现确认提示，但是确认后就没反应了
但是将button的type改为submit却又能提交
于是上jQuery API查找原因，看到以下这段文字顿时明白了：
Additional Notes:
Forms and their child elements should not use input names or ids that conflict with properties of a form, such as submit, length, or method. Name conflicts can cause confusing failures. For a complete list of rules and to check your markup for these problems, see DOMLint.
大概意思是表单和其子元素不宜用一个表单的属性的属性作为name或id的名称，如submit, length, 和 method等，否则会产生冲突，名称冲突可能就会导致这种情况。
原来是因为按钮id设为了submit
接下来只要将id改了就没问题了
