Javascript 使用jQuery修改类 测试 测试 测试 测试 测试 测试 设置1 设置2 设置3 第4组​ ​$（'.set'）。单击（函数（）{ $（“#这里”）。？？？ })​

我想-如果我点击.set，那么这应该得到自己的类并全部替换。这里

例如，如果我单击集合2，则所有span with class.如下所示：

<span class="here one-two-del-del other1">test</span>
<span class="here one-two-aaa o2ther">test</span>
<span class="here one-two-dsf other3">test</span>
<span class="here one-two-213 o4ther">test</span>
<span class="here one-two-sdf other5">test</span>
<span class="here one-two-sdff o6ther">test</span>

<span class="set one-two-aaaa">set 1</span> <br />
<span class="set one-two-bb-fff">set 2</span> <br />
<span class="set one-two-vcvc">set 3</span> <br />
<span class="set one-two-fgdfg-dfgfd-fgf">set 4</span> <br />​

​$('.set').click(function(){
  $('#here').???
})​

我不能使用removeClass，因为我不知道当前的类是怎样的。如果我使用.attr（'class'，'new'），那么它将替换所有类，但我必须仍然使用类other1，o2ther等

也许我必须使用正则表达式？

HTML

​<span class="here one-two-bb-fff other1">test</span>
<span class="here one-two-bb-fff o2ther">test</span>
<span class="here one-two-bb-fff other3">test</span>
<span class="here one-two-bb-fff o4ther">test</span>
<span class="here one-two-bb-fff other5">test</span>
<span class="here one-two-bb-fff o6ther">test</span>

这里有一个问题：

有几个类属性会使您的文档无效。您不需要多个“类”属性。没有有效的标记。不能多次使用class属性。

<span class="here one-two-del-del other1">test</span>
<span class="here one-two-aaa o2ther">test</span>
<span class="here one-two-dsf other3">test</span>
<span class="here one-two-213 o4ther">test</span>
<span class="here one-two-sdf other5">test</span>
<span class="here one-two-sdff o6ther">test</span>

<br />

<span class="set one-two-aaaa">set 1</span> <br />
<span class="set one-two-bb-fff">set 2</span> <br />
<span class="set one-two-vcvc">set 3</span> <br />
<span class="set one-two-fgdfg-dfgfd-fgf">set 4</span>

$('.set').click(function () {
    var replaceWith = $(this).attr('class');
    // Remove the "set " from replaceWith
    replaceWith = replaceWith.replace(/set ?/g, '');

    $('.here').each(function () {
        var newClass = $(this).attr('class');
        newClass = newClass.replace(/one-two-[^ $]+/, '');
        newClass = newClass + ' ' + replaceWith;
        // Now set the new class
        $(this).attr('class', newClass);
    });
})
