当我在弹出窗口中时，我在下拉列表中显示组合框数据时遇到问题 我的剑道网格中的编辑模式。当网格中的可编辑参数更改为“内联”时，组合框的行为就像它应该的那样。我认为问题出在自定义弹出模板上，但多次更改仍然没有结果。
这是 .cshtml 文件中的脚本:
<script id="popup_editor" type="text/x-kendo-template">
<label for="name">Page Name</label>
<input name="name"
data-bind="name"
data-value-field="id"
data-text-field="name"
data-role="combobox" />
</script>
这是 JavaScript:
var griddata = new kendo.data.DataSource({
transport: {
read: {
url: serviceRoot + "Approval/Get",
type: "POST",
contentType: jsonType,
cache: false
},
destroy: {
url: serviceRoot + "Approval/Delete",
type: "PUT",
complete: function(e) {
refreshData();
}
},
create: {
url: serviceRoot + "Approval/Create",
type: "PUT",
complete: function(e) {
refreshData();
}
},
update: {
url: serviceRoot + "Approval/Inline",
type: "PUT",
complete: function(e) {
refreshData();
}
}
},
pageSize: 10,
serverPaging: true,
serverFiltering: true,
serverSorting: true,
scrollable: true,
height: 700,
schema: {
data: "list",
total: "total",
model: {
id: "id",
fields: {
id: { editable: false, nullable: false },
name: { editable: true, nullable: false, validation: { required: true }, type: "string" },
keyName: { editable: true, nullable: false, validation: { required: true }, type: "string" },
countryName: { editable: true, nullable: false, validation: { required: true }, type: "string" },
}
}
}
});
$("#grid").kendoGrid({
dataSource: griddata,
selectable: "row",
allowCopy: true,
scrollable: true,
resizable: true,
reorderable: true,
sortable: {
mode: "single",
allowUnsort: true
},
toolbar: [{ name: "create", text: "Create New Content" }}],
edit: function(e) {
if (e.model.isNew() === false) {
$('[name="PageName"]').attr("readonly", true);
}
},
columns: [
{ field: "id", hidden: true },
{ field: "name", title: "Page Name", editor: PageNameComboBoxEditor, width: "200px" },
{
command: [
{ name: "edit" },
{ name: "destroy" }
],
title: " ",
width: "250px"
}
],
editable: {
mode: "popup",
template: kendo.template($("#popup_editor").html())
},
pageable: {
refresh: true,
pageSizes: [5, 10, 15, 20, 25, 1000],
buttonCount: 5
},
cancel: function(e) {
$("#grid").data("kendoGrid").dataSource.read();
}
});
function PageNameComboBoxEditor(container, options) {
ComboBoxEditor(container, options, "name", "id", "ApprovalPage/Get", options.model.id, options.model.name);
}
function ComboBoxEditor(container, options, textfield, valuefield, url, defaultid, defaultname) {
$("<input required data-text-field=\"" + textfield + "\" data-value-field=\"" + valuefield + "\" data-bind=\"value:" + options.field + "\"/>")
.appendTo(container)
.kendoComboBox({
autoBind: false,
dataTextField: textfield,
dataValueField: valuefield,
text: defaultname,
value: defaultid,
select: function(e) {
var dataItem = this.dataItem(e.item);
var test = dataItem;
},
dataSource: {
transport: {
read: {
url: serviceRoot + url,
type: "GET"
}
}
}
});
}
任何方向将不胜感激!
最佳答案
首先，我注意到您有拼写错误和一些双重初始化，并且指定的值不同，这会导致问题(不确定这是否是您的问题，所以请尝试删除它)，
<input name="name"
data-bind="name" -> typo maybe? no data-binding declaration like these
data-value-field="id" -> double init, you have it on your ComboBoxEditor function dataValueField: valuefield,
data-text-field="name" -> double init, you have it on your ComboBoxEditor function dataTextField: textfield,
data-role="combobox" />
但要使其正常工作，我通常会自定义编辑功能来为mode: popup声明kendo小部件，如下所示:
