原标题:In jQuery what s the best way to add a class on mouseover and remove it on mouseout?

是否有 j?

$(element).on("mouseover", function() {
    $(this).addClass("hover");
}).on("mouseout", function() {
    $(this).removeClass("hover");
});

我在“jQuery docs”中看到一种称为“hover(),但似乎对mouseenter<>/code>和>mouseleave的约束。 (我是否应当利用这些活动而不是<代码>Mouseovermouseout?)

最佳回答

Description

You can user jQuery s hover() method.

http://jsfiddle.net/T5aXb/1/“jsFiddle Demonstration。

Sample

$(elem).hover(function(ev) {
    $(this).addClass( hover );
}, function(ev) {
    $(this).removeClass( hover );
});

问题回答

The simplest way, to remove duplication of code, is by passing one argument to hover and use toggleClass:

$(elem).hover(function() {
    $(this).toggleClass( hover );
});

或:

$(element).hover(function () {
    $(this).addClass("hover");
}, function () {
    $(this).removeClass("hover");
});

<>代码>hover()只是一个比值更强的契约:

$(elem).hover(function(ev) {
    $(this).addClass( hover );
},function(ev) {
    $(this).removeClass( hover );
});

For the differences between mouseover/mouseout and mouseenter/mouseleave, see 湿use和 mo之间有何区别?
