Question

我有许多跨度，我需要分组以在悬停后改变不透明度，所有这些都需要有唯一的ID，有没有办法将所有这些悬停函数组合成一个函数？

Answer 1

您有三种选择：

将您的班级用作选择器：

$('.mieszkanie').hover(
    function() {
        $(this).stop(true, true).css('opacity','1');
    },
    function() {
        $(this).stop(true, true).css('opacity','0');
});

在同一个选择器中添加所有ID：

$('#c_09_245a, #c_09_245b, #c_09_246a, #c_09_246b, #c_09_247a, #c_09_247b').hover(
    function() {
        $(this).stop(true, true).css('opacity','1');
    },
    function() {
        $(this).stop(true, true).css('opacity','0');
});

制作两个能够执行所需操作的函数来减少代码：

function show () {
    $(this).stop(true, true).css('opacity','1');
}

function hide () {
    $(this).stop(true, true).css('opacity','0');
}

$(selector).hover(show, hide);

Answer 2

您可以在大多数带有触发事件的元素的jQuery事件处理程序中使用this。尝试类似：

$('.rzuty>span').hover(function() {
    $(this).stop(true, true).css('opacity',1);
}, function() {
    $(this).stop(true, true).css('opacity',0);
});

或者如果您想要更具体，请添加一个类并在选择器中使用它。

Answer 3

对马特来说，我们有最终答案

var ids = [
    "#c_07_227a, #c_07_227b",
    "#c_07_228a, #c_07_228b, #c_07_228c"
    // add more here
];

ids.forEach(function(i) {
    $(i).hover(function() {
        $(i).stop(true, true).css('opacity', '1');
    }, function() {
        $(i).stop(true, true).css('opacity', '0');
    });
});

如何组合这些悬停功能
