我想实现这样的功能:<input type="checkbox" name="hmd" value="1" onclick="heidan(this);" />
启动黑名单设置
<a id="hd1">设置黑名单</a>function heidan(th){
if(th.checked == true){
document.getElementById("hd1").href="javascript:opens()";
}else{
document.getElementById("hd1").href=false;//取消href不能点击
}
}

<a id="hd1">设置黑名单</a>function heidan(th){
if(th.checked == true){
document.getElementById("hd1").href="javascript:opens()";
}else{
document.getElementById("hd1").href=false;//取消href不能点击
}
}
document.getElementById("hd1").href = "javascript:opens()";
} else {
document.getElementById("hd1").setAttribute("href", "#");
}
