今天寫表單提交的時(shí)候需要增加一個(gè)確認(rèn)提示，所以沒有使用submit按鈕提交，改用jq的submit()，然后問題了

<form class="form-horizontal m-t" method="post" action=http://www.3lian.com/edu/2017/04-28/"@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">開始時(shí)間：</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">結(jié)束時(shí)間：</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=http://www.3lian.com/edu/2017/04-28/"@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('請(qǐng)確認(rèn)所填寫的信息是否正確？<br/>開始時(shí)間：' + start + '<br/>結(jié)束時(shí)間：' + end + '<br/>年利率:' + val, { icon: 3, title: '提示' }, function (index) { $("#form").submit(); layer.close(index); }); }); }) </script>

點(diǎn)擊提交按鈕出現(xiàn)確認(rèn)提示，但是確認(rèn)后就沒反應(yīng)了

但是將button的type改為submit卻又能提交

于是上jQuery API查找原因，看到以下這段文字頓時(shí)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.

大概意思是表單和其子元素不宜用一個(gè)表單的屬性的屬性作為name或id的名稱，如submit, length, 和 method等，否則會(huì)產(chǎn)生沖突，名稱沖突可能就會(huì)導(dǎo)致這種情況。

原來是因?yàn)榘粹oid設(shè)為了submit

接下來只要將id改了就沒問題了
