Javascript get nextSibling不是类“foo”

试试这个:

if (elem.nextSibling && !/(?:^|\s+)foo(?:\s|$)/.test(elem.nextSibling.className)) {
    // there is a next sibling that does not have the class foo
}

类名 下一页

if (/(?:^|\s)foo(?:\s|$)/.test(el.nextSibling.className)) {
    // next sibling has foo class
}

如果要查找下一个没有该类的元素,可以执行以下操作:

var el = document.getElementById("myEl");

while (el = el.nextSibling) {
    if (!(/(?:^|\s)foo(?:\s|$)/.test(el.className)))
        break;
}

// el is either null, or an element that doesn't have the foo class

试试这个密码,

x=myEl.nextSibling;
while (x.nodeType!=1)
{
    if(x.className=="foo"){
       x=x.nextSibling;
    }
}
return x;
