<pre><code>&lt;div ng-show="form.password.$error.required &amp;&amp; form.password.$dirty"&gt;Password required&lt;/div&gt;
</code></pre>

<p>You can do this by adding condition of dirty field. So if the field will be dirt then only it will show error</p>

<p>This should work using the <code>$pristine</code> property.</p>

<pre><code>&lt;div ng-show="!form.password.$pristine &amp;&amp; form.password.$error.required"&gt;Password required&lt;/div&gt;
</code></pre>

<p><code>$pristine</code> returns true if user has not interacted with the control yet. </p>

blocks|key|389426|text|您可能希望类似于$dirty+(从默认值更改)或$touched+(根据您的模型选项至少模糊一次，可能是您想要的)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|389427|示例|389428|form+name="form">

<p>You'd want something like <code>$dirty</code> (changed from default value) or <code>$touched</code> (blurred at least once, probably what you want, based on your model options).</p>

<h2>Example</h2>

<pre><code>form name="form"&gt;
    &lt;input type="email" ng-model-options="{ updateOn: blur }" required /&gt;
    &lt;input type="password" ng-model-options="{ updateOn: blur }" required /&gt;
    &lt;div ng-messages="form.password.$error" ng-if="form.password.$touched"&gt;
      &lt;div ng-message="required"&gt;Password required&lt;/div&gt;
    &lt;/div&gt;
&lt;/form&gt;
</code></pre>

<p>I used <code>ng-messages</code> here because it's neat, but you don't have to use it, you can just add the condition to your <code>ng-show</code> / <code>ng-if</code>.</p>

<p>I have a form with two fields:</p>

<pre><code>&lt;form name="form"&gt;
    &lt;input type="email" ng-model-options="{ updateOn: blur }" required /&gt;
    &lt;input type="password" ng-model-options="{ updateOn: blur }" required /&gt;
    &lt;div ng-show="form.password.$error.required"&gt;Password required&lt;/div&gt;
&lt;/form&gt;
</code></pre>

<p>The error div is always displayed when the password field is empty - I only want it to display if the password has been focused and then blurred. Is there a simple change I can make to enable this?</p>
