当我在代码中使用样式化类时,为什么javascript代码不起作用?

当我在代码中使用样式化类时,为什么javascript代码不起作用?,javascript,class,checkbox,Javascript,Class,Checkbox,但当我删除样式化类时,它可以正常工作。 我的风格类代码是这样的 onclick="document.getElementById(q11_1).checked=false if(输入[a]。选中==true){ 如果(输入[a]。类型==“复选框”){ position=“0-”+(复选框高度*2)+“px”; span[a].style.backgroundPosition=位置; }否则{ position=“0-”+(无线电高度*2)+“px”; span[a].style.backgr

但当我删除样式化类时,它可以正常工作。 我的风格类代码是这样的

onclick="document.getElementById(q11_1).checked=false
if(输入[a]。选中==true){
如果(输入[a]。类型==“复选框”){
position=“0-”+(复选框高度*2)+“px”;
span[a].style.backgroundPosition=位置;
}否则{
position=“0-”+(无线电高度*2)+“px”;
span[a].style.backgroundPosition=位置;
}
}
输入[a].parentNode.insertBefore(span[a],输入[a]);
输入[a]。onchange=Custom.clear;
如果(!inputs[a].getAttribute(“已禁用”)){
span[a].onmousedown=Custom.push;
span[a].onmouseup=Custom.check;
}否则{
span[a].className=span[a].className+=“已禁用”;
}
}
}
输入=document.getElementsByTagName(“选择”);
对于(a=0;a
} window.onload=Custom.init

我想您需要引用标识符

document.forms['foo'].bar[0].checked=false;

你所说的“风格类”是什么意思?您的id中缺少了“”,比如getElemntById('id')您所说的“样式化类”是什么意思?您的id中缺少了“”,比如getElemntById('id')是的,但当我使用styled类时,它也不起作用,否则,如果您正确命名所有内容,workCSS不应该成为问题。如果另一个人建议引用标识符
