Add Item To kendoDropDownList
提问by Hector
I am trying to add a item to the kendoDropDownList, it seems to add the option but not set the value and text. Inspecting the select it just adds a new option
我正在尝试向 kendoDropDownList 添加一个项目，它似乎添加了选项但没有设置值和文本。检查选择它只是添加了一个新选项
<option></option>
Here is what I am using
这是我正在使用的
$("#nameList").data("kendoDropDownList")
.dataSource.add({ "text": "Joe", "value": "Joe" });
UPDATE
更新
Here is my datasource model and the requestEndas suggested but the values seem to get messed up
这是我的数据源模型和requestEnd建议的但值似乎搞砸了
datasource_people = new kendo.data.DataSource({
type: "json",
serverFiltering: true,
transport: {
read: {
dataType: 'json',
type: 'GET',
url: '/restful/people/'
}
},
filter: {
field: "status",
operator: "eq",
value: 1
},
schema: {
data: function(response) {
return response.data.plaintiffs;
},
model: {
id: "person_id",
fields: {
person_id: {type: "number"},
name: { type: "string"}
}
},
errors: "error",
total: function(response) {
return response.data.total;
}
}
});
Then Later
然后后来
$("#people_list").kendoDropDownList({
dataTextField: "text",
dataValueField: "value",
dataSource: {
datasource_people,
requestEnd: function (e) {
e.response.push({text: "John", value: "John"});
}
}
});

After some searching it was quite simple but this worked for exactly what i needed.
经过一番搜索后，它非常简单，但这正是我所需要的。
$("#people_list").getKendoDropDownList().dataSource.insert({
person_id: "John",
name: "John"
})

You can add a new item to the datasource after it has been loaded using requestEnd.
您可以在使用requestEnd加载新项目后向数据源添加新项目。
requestEnd: function (e) {
e.response.push({text: "Joe", value: "Joe"});
}
I've updated the other user's fiddle to show you it works. jsFiddle example
我已经更新了其他用户的小提琴以向您展示它的工作原理。 jsFiddle 示例

Use this:
用这个：
<input id="nameList" value="1" />
var data = [
{ text: "Joe", value: "Joe" },
{ text: "Joe", value: "Joe" },
{ text: "Joe", value: "Joe" }
];
// create DropDownList from input HTML element
$("#nameList").kendoDropDownList({
dataTextField: "text",
dataValueField: "value",
dataSource: data,
index: 0,
});

Not sure what exactly you want, but you can load options from a datasource, and then append more to the list after dataBoundhas fired.
不确定您到底想要什么，但您可以从数据源加载选项，然后在dataBound触发后将更多选项附加到列表中。
$("#nameList").kendoDropDownList({
dataTextField: "text",
dataValueField: "value",
dataSource: {
transport: {
read: {
dataType: 'json',
type: 'GET',
url: '/restful/companies'
}
}
},
dataBound:onDataBound
});
<script>
function onDataBound(e) {
e.sender.dataSource.add({ "text": "Joe", "value": "Joe" });
}
</script>
