jQuery hover() 方法

❮ jQuery 事件方法

示例

当鼠标指针悬停在 <p> 元素上时,更改其背景颜色

$("p").hover(function(){
  $(this).css("background-color", "yellow");
  }, function(){
  $(this).css("background-color", "pink");
});
亲自试一试 »

定义和用法

hover() 方法指定了两个函数,当鼠标指针悬停在选定的元素上时运行。

此方法会触发 mouseentermouseleave 事件。

注意:如果只指定了一个函数,则该函数将同时用于 mouseenter 和 mouseleave 事件。


语法

$(选择器).hover(进入函数,离开函数)

参数 描述
inFunction 必需。指定当 mouseenter 事件发生时要运行的函数
outFunction 可选。指定当 mouseleave 事件发生时要运行的函数
