ng自带的表单验证

几点注意：使用ng的表单验证，需要给form,input,textarea一个name

要求：验证输入框的内容(长度，正则，必填，)，当验证不通过的时候，就禁用提交按钮

使用的验证：ng-maxlength
,ng-minlength ,ng-pattern ,required ,ng-disabled

input的type=“url,email,number,

html:

<form name="idea_info" novalidate>

<!---novalidate阻止浏览器的默认验证--->

<input type="text" name="idea_title" autocomplete="off" required
ng-minlength="5" ng-maxlength="20" class="form-control
my-panel-title" placeholder="创意标题" ng-model="ideas.name"/>

<div>

<p class="my-help-block"
ng-show="idea_info.idea_title.$error.minlength ||
idea_info.idea_title.$error.maxlength || idea_info.idea_title.$dirty&&idea_info.idea_title.$invalid">标题名5-20个字符</p>

     <p
class="my-help-block" ng-show="idea_info.idea_title.$error.required || idea_info.idea_title.$dirty&&idea_info.idea_title.$invalid">标题名必填</p>

</div>

<input name=”use_phoner” ng-pattern=”/^1[3,4,5,8,9]\d{9}&/”/>

 <!---ng-pattern="/^(13[0-9]|14[0-9]|15[0-9]|17[0-9]|18[0-9])\d{8}$/i"-->

<div>

<p class="my-help-block" ng-show="idea_info.use_phoner.$error.pattern>请输入合法的手机号码格式</p>

</div>

<!--按钮的禁用--->

<p
class="bottom-btn 
text-right">

    <button type="submit"
class=" my-btn-lg "
ng-click="addIdeas()"  ng-class="{'active':!idea_info.$invalid}" ng-disabled="idea_info.$invalid" >保存</button>

    <button class=" my-btn-lg
btn-outline-green" 
ng-click="cancel_save()">取消</button>

</p>

</form>
