首先，我想自动隐藏div部分，然后如果我单击添加监护人按钮。它将显示div部分。这是我的密码。提前谢谢。我也在这里指出我的脚本。请查收，谢谢！

由于您使用的是Bootstrap，所以只需使用collapse组件即可。。

代码中的一个小错误，您有==，需要一个=

divelement.style.display = 'block';
else
divelement.style.display = 'none';
function toggle_div_fun(id){

<!-- End Guardian -->这里我给你一个简短的演示。下面是你的例子。在那里你必须用类"Your_class"来切换DIV。
HTML
<div class="Your_Class">
"Your Content"
</div>
<button onClick="toggle_div_fun('guardian');" type="button" class="btn btn-icon btn-primary icon-left">Add Guardian<i class="fa fa-plus"></i></button>
CSS
.Your_Class { display:none;}
.Your_Class.active { display:block;}
JS
$(".btn-primary").click(function(){
if($(".Your_Class").hasClass('active')) {
$(this).removeClass('active');
}
else
{
$(this).addClass('active');
}
});
