我正在尝试将带有.css()
方法的样式添加到使用.get()
:
$( .toggle ).get(0).css("display", "none");
…但那不管用。我做错了什么?
是你想做的
$( .toggle ).first().css("display", "none");
get(0)返回一个DOM对象,而不是jQuery对象。
jQuery s.get()方法
返回纯DOM元素。
您应该使用jQuery s.eq()
方法按索引选择时使用。
$( .toggle ).eq(0).css("display", "none");
这将在您指定的索引处返回一个带有DOM元素的jQuery对象,因此您将能够针对它调用jQuery方法。
$( .toggle:eq(0) )
或
$( .toggle:first )
Also, jQuery has .show()
and .hide()
methods to set the display property. Or perhaps .toggle()
is m或e appropriate considering the class name.
