1,在给一个layer弹出层做checkbox自动选中时,ViewBag传递的时object类型,用不了lambda表达式,代码如下,
@foreach (var perm in ViewBag.allPerms)
{
<input type="checkbox" id="permissionIds_@perm.Id"
name="PermissionIds" value="@perm.Id"
checked="@(ViewBag.RolePerms.Select(r=>r.Id).Contains(perm.Id))"/>
<label for="permissionIds_@perm.Id">@perm.Name</label>
}
2,于是在弹出层就不写foreach循环遍历checkbox,直接在点击编辑事件时的弹出层中 ‘添加层弹出后的成功回调方法success’ ,在里面通过ajax填充数据
Control中Edit方法获取数据
//填充角色数据并显示
public ActionResult Edit(long roleId = 0)
{
if (roleId == 0)
{
return Json(new JsonData { State = 0, ErrorMsg = "角色不存在!" });
}
var role = RoleService.GetById(roleId);
if (role==null)
{
return Json(new JsonData { State = 0, ErrorMsg = "角色Id不存在!" });
}
var allPerms = PermissionService.GetAll();
var rolePerms = PermissionService.GetByRoleId(roleId);
RoleEditGetModel model = new RoleEditGetModel();
model.RolePerms = rolePerms;
model.AllPerms = allPerms;
return Json(new JsonData { State = 1, Data = model });
}
View中Layer弹出层success方法
success: function (layero, index) {
//填充数据
$.ajax({
url: "/Role/Edit?roleId=" + id,
type: "post",
dataType: "json",
success: function (res) {
if (res.State == 1) {
var html = "";
var bool = false;
for (var i = 0; i < res.Data.AllPerms.length; i++) {
bool = false;
for (var j = 0; j < res.Data.RolePerms.length; j++) {
if (res.Data.RolePerms[j].Id == res.Data.AllPerms[i].Id) {
bool = true;
break;
}
}
html += ' <input ' + (bool ? "checked" : "") + ' type="checkbox" id="permissionIds_' + res.Data.AllPerms[i].Id + '" name="PermissionIds" value="' + res.Data.AllPerms[i].Id + '" />
<label for="permissionIds_' + res.Data.AllPerms[i].Id + '">' + res.Data.AllPerms[i].Name + '</label>'
}
$("#formValue").html(html);
}
},
error: function () {
layer.alert('网络请求失败!', {
title: '提示框',
icon: 0,
});
}
});
},
