我想为我的 ForigenKey 列显示文本而不是数值。有很多通过比较 ID 来检索 TextMember 的示例,但在我的情况下它们不起作用。我刚开始使用剑道ui,所以不太了解
这是代码:
$(document).ready(function () {
dataSource1 = new kendo.data.DataSource({
transport: {
read: {
url: "Data/AttendanceCode/GridSelect.php",
dataType: "json",
},
update: {
url: "Data/AttendanceCode/GridUpdate.php",
dataType: "json",
type:"GET"
},
destroy: {
url: "Data/AttendanceCode/GridDelete.php",
dataType: "json",
type:"POST"
},
create: {
url: "Data/AttendanceCode/GridInsert.php",
dataType: "json",
type:"POST"
},
},
schema: {
data: "data",
model: {
id: "AttendenceID",
fields: {
AttendenceID : { editable: false, nullable: true },
TeacherID: { field: "TeacherID", defaultValue: "EIIT0002" },
}
}
},
});
$("#grid").kendoGrid({
dataSource: dataSource1,
pageSize: 10,
pageable: {
refresh: true,
pageSizes: true
},
editable:{ mode : "popup" },
height: 400,
filterable: true,
columnMenu: true,
sortable: true,
reorderable: true,
resizable: true,
toolbar: ["create"],
columns: [
{ field:"AttendenceID", title: "Attendence ID", width:"130px" },
{ field: "TeacherID", title:"Teacher", width: "100px" , editor: TeacherDropDownEditor, template: "#=getTeacherName(TeacherID)#" },
{ command: ["edit", "destroy"], title: "Action", width: "210px" }],
});
});
教师下拉数据源
teacher = new kendo.data.DataSource({
transport: {
read: {
url : "Data/Teacher.php",
dataType: "json" }
},
schema: {
data : "Teacher"
}
});
//教师编辑
function TeacherDropDownEditor(container, options) {
$('<input data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
dataTextField: "TeacherName",
dataValueField: "Service_NO",
dataSource: teacher
});
}
我发现并尝试获取教师姓名的不同方法
1 -
function getTeacherName(value) {
var text = "";
$.each(teacher, function () {
if (this.Service_NO == value) {
text = this.Name;
return false;
}
});
return text;
}
2 -
function getTeacherName(teacherID) {
for (var idx = 0, length = teacher.length; idx < length; idx++)
{
if (teacher[idx].Service_NO === teacherID)
{t = teacher[idx].Name;}
}
return t;
}
3 -
function getTeacherName(teacherID) {
$.each(teacher, function(key, val) {
if(val.Service_NO == tID){
t = val.Name;
}
});
return t;
}
似乎 dataSource(老师)没有任何价值。PHP 代码运行良好。如果您知道我的代码有什么问题,请提供帮助。
谢谢 !!
