模板是
<button type="submit" id="add" class="button_style" onclick="addreporter();" value="Add New Authorised Reporter">Add New Authorised Reporter</button>
<div id="authorisedreporter" style="display:none">
<form method="post" action="{% url incident.views.about_me %}">{% csrf_token %}
<table width="100%">
<tr>
<td style="width:100px;">First name:</td>
<td>{{registerform.first_name}}{{registerform.first_name.errors}}</td>
</tr>
<tr>
<td>Last name:</td>
<td>{{registerform.last_name}}{{registerform.last_name.errors}}</td>
</tr>
<tr>
<td>Daytime phone:</td>
<td>{{createprofile.phone_daytime}}{{createprofile.phone_daytime.errors}}</td>
</tr>
<tr>
<td>Mobile phone:</td>
<td>{{createprofile.phone_mobile}}{{createprofile.phone_mobile.errors}}</td>
</tr>
<tr>
<td>Email:</td>
<td>{{registerform.email}}{{registerform.email.errors}}</td>
</tr>
<tr>
<td>User name</td>
<td>{{registerform.username}}{{registerform.username.errors}}</td>
</tr>
<tr>
<td>Password</td>
<td>{{registerform.password}}{{registerform.password.errors}}</td>
</tr>
<tr>
<td colspan=2 "">
<input type="checkbox" name="is_qualified_firstaiders" style="margin: 0;vertical-align:middle" />Qualified First Aiders</td>
</tr>
</table>
</form>
</div>
js：
function addreporter(){
$("#authorisedreporter").toggle();
if ($("#authorisedreporter").is(":visible")) {
$("#authorisedreporter").show();
$("#add").hide();
}
}
使用jquery切换，点击打开 <button>Add new Authorized Reporter</button>，一切都很好，除了如果表单中有任何错误，表单将处于隐藏模式，如果我想再次查看错误，我需要点击 <button>Add new Authorized Reporter</button>，它是一个小逻辑来设置错误是否在表单中，表单不应该隐藏。我想的是，如果我验证display:nonein <div> 将起作用，但不知道如何在模板中验证它。
谢谢
