这段代码是在查看问卷调查结果的时候用到的,一份问卷里面有单选题、多选题和问答题,(我这里不考虑最简单的问答题),
我的方法是:所有选项前面都有一个input,单选就是radio,多选就是checkbox,将查询到的结果进行判断,已选的选项前再加上
一个input,属性checked=“checked”,并将刚刚的input隐藏。
for (var k = 0; k < result.length; k++) {
var realIds = result[k] - 99;
if(realIds>0){
document.getElementById(realIds).style.display = "none";
}
}
for (var j = 0; j < result2.length; j++) {
var ids = result2[j] - 100;
if(ids>0){
document.getElementById(ids).style.display = "none";
}
}
其中result[k]-99,表示的是选中的选项是有两个input的,只是将其中一个没选中的隐藏了。

大家要看的只是我得到checked的属性的id就可以了,其他的可作为参考。
