我希望没有身体可以在没有提供名称的情况下保存表格，这里是我的Html代码..我做错了什么我不知道..我检查了很多解决方案请给我一个理由...我想知道我将如何提供前端验证

您可以使用required并查看它是否有帮助？
<input type="text" name="name" required>
答案 1 :(得分：0)
当你这样做时，只需添加@thepio的答案
<input type="text" name="name" ng-model="calendar.name"
placeholder="Enter calendar name" required >
<input type="submit" ng-disabled="!frmType.$valid">
最后一行将禁用您的提交按钮，直到用户在其中键入内容。
如果你想检查所有字母是否都是我建议使用ng-pattern的字样。
我在代码中使用的一个例子
<div class="form-group">
<label class="control-label">Executive Name</label>
<input class="form-control placeholder-no-fix" type="text" autocomplete="off" placeholder="Executive Name" name="execName" ng-model="user.execName" ng-pattern="/^[A-z ]*$/" required />
<span class="error" ng-show="createForm.execName.$error.required && createForm.execName.$touched">required</span>
<span class="error" ng-show="createForm.execName.$error.pattern && createForm.execName.$dirty">Must start with a letter, and contain letters only.</span>
</div>
答案 2 :(得分：0)
您可以使用ng-message验证，如：
<form name="form" validate>
<input id="name" name="name" md-maxlength="25"
ng-model="name" required autocomplete="false">
<div ng-messages="form.name.$error">
<div ng-message="required">Name field can not empty</div>
</div>
</form>
