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]);
    }
}

演示:http://jsfiddle.net/L2A27/1/

$('div').attr('class', function(i, c){
    return c.replace(/(^|\s)color-\S+/g, '');
});

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;
};

如果你有多个元素的类名为“example”，要删除所有的“color-”类，你可以这样做:

var objs = $('html').find('.example');
for(index=0 ; index < obj1s.length ; index++){
    objs[index].className = objs[index].className.replace(/col-[a-z1-9\-]*/,'');
}

如果你不把[a-z1-9-]*放在你的正则表达式中，它不会删除名字中有数字或一些“-”的类。
