在单词边界上拆分正则表达式\b并不是最好的解决方案:

var prefix = "prefix";
var classes = el.className.split(" ").filter(function(c) {
    return c.lastIndexOf(prefix, 0) !== 0;
});
el.className = classes.join(" ");

或作为jQuery mixin:

$.fn.removeClassPrefix = function(prefix) {
    this.each(function(i, el) {
        var classes = el.className.split(" ").filter(function(c) {
            return c.lastIndexOf(prefix, 0) !== 0;
        });
        el.className = classes.join(" ");
    });
    return this;
};

从jQuery 1.4开始，removeClass函数就带有一个函数参数。

$("#hello").removeClass (function (index, className) {
    return (className.match (/(^|\s)color-\S+/g) || []).join(' ');
});

我已经写了一个插件，做这个叫做alterClass -删除元素类通配符匹配。可选地添加类:https://gist.github.com/1517285

$( '#foo' ).alterClass( 'foo-* bar-*', 'foobar' )

类似于@tremby的答案，这里是@Kobi的答案作为一个插件，将匹配前缀或后缀。

ex)剥离btn-mini和btn-danger，但当stripClass(“btn-”)时不剥离btn。 当stripClass('btn'， 1)剥离马btn和牛btn，但不剥离btn-mini或btn

代码:

$.fn.stripClass = function (partialMatch, endOrBegin) {
    /// <summary>
    /// The way removeClass should have been implemented -- accepts a partialMatch (like "btn-") to search on and remove
    /// </summary>
    /// <param name="partialMatch">the class partial to match against, like "btn-" to match "btn-danger btn-active" but not "btn"</param>
    /// <param name="endOrBegin">omit for beginning match; provide a 'truthy' value to only find classes ending with match</param>
    /// <returns type=""></returns>
    var x = new RegExp((!endOrBegin ? "\\b" : "\\S+") + partialMatch + "\\S*", 'g');

    // https://stackoverflow.com/a/2644364/1037948
    this.attr('class', function (i, c) {
        if (!c) return; // protect against no class
        return c.replace(x, '');
    });
    return this;
};

我们可以通过.attr("class")获取所有的类，和数组，循环和过滤器:

var classArr = $("#sample").attr("class").split(" ")
$("#sample").attr("class", "")
for(var i = 0; i < classArr.length; i ++) {
    // some condition/filter
    if(classArr[i].substr(0, 5) != "color") {
        $("#sample").addClass(classArr[i]);
    }
}

删除任何以begin开头的类的泛型函数:

function removeClassStartingWith(node, begin) {
    node.removeClass (function (index, className) {
        return (className.match ( new RegExp("\\b"+begin+"\\S+", "g") ) || []).join(' ');
    });
}

http://jsfiddle.net/xa9xS/2900/

Var begin = 'color-'; 函数removeClassStartingWith(node, begin) { 节点。removeClass(函数(索引，className) { 返回(类名。(新RegExp匹配(“\ \ b”+ +“\ \ S +”开始,“g ") ) || []).加入(' '); })； ｝ removeClassStartingWith($(' #你好'),“颜色——”); console.log($(" #你好”)[0].className); < script src = " https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js " > < /脚本> <div id="hello" class="color-red - color-brown foo bar"></div>
