js:
$(document).ready(function() {
    $.get("/account/authGroupInfo",{id:groupId}, function(data) {
        var arr = data.data.rules.split(",");
        console.log(arr);
        $.get("/account/allRule",{}, function(result) {
            ruleList.options = result.data;
//问题所在
            ruleList.$nextTick(function () {
                $(".auth_rules").each(function () {
                    if($.inArray($(this).attr("id"),arr)>-1) {
                        $(this).prop('checked',true);
                    }
                })
            })
        });
    });
});
 
html:
<tr v-for="value in options">
   <td><input type="checkbox" id="{{value.id}}" value="{{value.id}},"  class="auth_rules">{{ value.title }}</td>
</tr>
使用
  ruleList.$nextTick(function () {}) 拿到更新后的dom
