必填表格中的自动完成输入字段

Question

我有一个字段，我希望将其作为表单提交的必填字段。

这里是代码：

<div class="form-group"> 
    <form name="addressform"> 
     <span><small><strong> choose Location : </small></strong></span> 

     <div> 
      <input type="text" name="address" id="LocationAutocomplete" class="form-control" ng-autocomplete="result1" ng-model="addressTemp" required/> 
</form> 
      <div ng-show="showMap"> 
       <div id="location_map_canvas" style="width:100%;height:200px"> </div> 
      </div> 
     </div> 
    </div> 
    <div class="form-group"> 
        <input type="submit" ng-submit value="create" ng-disabled="frm.$invalid" class="btn btn-primary btn-block" ng-click="createt()"> 
        </div> 

Answer 1

试试这个工作演示：

var myApp = angular.module('myApp',[]); 
 

 
myApp.controller('MyCtrl', function($scope) { 
 
    $scope.create = function() { 
 
     console.log("submitting.."); 
 
    } 
 
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> 
 
<div ng-app="myApp" ng-controller="MyCtrl"> 
 
    <form name="addressform" ng-submit="addressform.$valid && create()" novalidate> 
 
     <span ng-show="submitted == true && addressform.address.$error.required">Required field.</span> 
 
     <div class="form-group"> 
 
      <input type="text" name="address" id="LocationAutocomplete" class="form-control" ng-autocomplete="result1" ng-model="addressTemp" required/> 
 
     </div> 
 
    <div class="form-group"> 
 
     <input type="submit" value="create" class="btn btn-primary btn-block" ng-click="submitted = true"> 
 
    </div> 
 
</form> 
 
</div>

<input name="movie" type="text" required />

这是你将如何做需要输入文本字段。

Answer 3

看看ngRequired

<input type="text" id="LocationAutocomplete" class="form-control" ng-autocomplete="result1" ng-model="addressTemp" ng-required="required"/> 

Answer 4

使用ng-required="true"如下：

<input type="text" id="LocationAutocomplete" class="form-control" ng-autocomplete="result1" ng-model="addressTemp" ng-required="true" name="input"/> 

<input type="submit" ng-disabled="myform.input.$error.required">Submit</input> 

Answer 5

使用angularjs表单验证 https://docs.angularjs.org/guide/forms - https://docs.angularjs.org/api/ng/type/form.FormController与NG-消息（https://docs.angularjs.org/api/ngMessages/directive/ngMessages）

，如果你想要提交（ng-submit =“checkAndSave”）.. 不要在控制器..

$scope.checkAndSave = function(){ 

// validations code if ok do save else throw whatever you want 
} 

Answer 6

添加的表单标签，并将其命名形式和所有的输入

<form name="form" ng-submit="submitform()"> 
    <input name="addres" type="text" id="LocationAutocomplete" class="form-control" ng-model="addressTemp" required/> 

    <button type="submit" ng-disabled="form.$invalid"> Submit </button> 
</form> 

有了这个，你将不得不如果输入是无效的提交按钮被禁用。 ，因为它具有必需的属性，如果输入为空，它将显示为无效。
