Jquery 前台checkbox赋值问题

Question

View中显示中国所有的省份
每个省份一个checkbox如果我数据库中有 上海 北京 两个省份那怎么在页面中把上海、北京两个checkbox的勾打上呢，其余的不变是通过JSON传值 还是怎么地？

Answer 1

是啊 我也是这么想的$(document).ready(function() {
            JudgeCheckBox();
        });        function JudgeCheckBox() {
            var url = "/AreaConfiguration/GetCheckBoxStatus/";
            $.getJSON(url, function(data) {
                $.each(data, function(i, item) {
                    $   ("#" + item ).attr("checked", true); //打勾
//                    $(":CheckBox").each(function() {
//                        if (($(this)[0].value == item[0])) {
//                            $(this)[0].checked = true;
//                        }
//                    });
                });
            });
        }        
写的对不对呢

Answer 2

$(document).ready(function() {
            JudgeCheckBox();
        });        function JudgeCheckBox() {
            var url = "/AreaConfiguration/GetCheckBoxStatus/";
            $.getJSON(url, function(data) {
                $.each(data, function(i, item) {
                    $("input:checkbox").each(function() {
                        if ($(this).val() = item[0]) {
                            $(this).attr("checked", 'true');
                        }
                    });
                });
            });
        } 
都不对额

Answer 3

                 应该是这样的：
           $(this).attr("checked", 'checked');
              

Answer 4

$(document).ready(function() {
            JudgeCheckBox();
        });
        function JudgeCheckBox() {
            var url = "/AreaConfiguration/GetCheckBoxStatus/";
            $.getJSON(url, { RegionName: ViewData["RegionName"], MoudleName: ViewData["MoudleName"] }, function(data) {
                $.each(data, function(i, item) {
                    $(":checkbox").each(function() {
                        //alert($(this).val());
                        if ($(this).attr("value") = item["ProvinceId"]) {
                            $(this).attr("checked", true);
                        }
                    });
                });
            });
        }      还是错的
