[英]Kendo UI grid radio button changed event not firing?
I have a Kendo grid which shows a questionnaire. 我有一个显示调查表的剑道网格。 The question id and question is fetched from the database using AJAX call.
问题ID和问题是使用AJAX调用从数据库中获取的。 I am adding the radio buttons to the grid at run-time.
我在运行时将单选按钮添加到网格中。
My problem is that the radio buttons are not firing the changed event. 我的问题是单选按钮未触发更改的事件。 My code is below:
我的代码如下:
<div style="height: 950px;" id="grdQuestions"></div>
<div style="text-align: center; margin-top: 10px;">
<button class="k-button" id="submitresults" type="submit">Submit Results</button>
</div>
<script>
$(document).ready(function () {
var dataSource = new kendo.data.DataSource({
transport: {
read: {
type: "GET",
url: "/AjaxHandler.aspx?requesttype=getquestions",
dataType: "json",
contentType: "application/json; chartset=utf-8"
}
},
pageSize: 25
});
$("#grdQuestions").kendoGrid({
dataSource: dataSource,
pageable: {
pageSizes: true
},
columns: [
{
field: "QuestionsId",
title: "Question Id",
width:90
},
{
field: "QuestionText",
title: "Question",
width:700
},
{
title: "Not me at all",
template: "<input class='radioq' type='radio' name=" + "'" + "select" + '#: QuestionsId #' + "'" + "id=" + "'" + "notme" + '#: QuestionsId #' + "'" + "/>",
},
{
title: "This is true some of the time",
template: "<input class='radioq' type='radio' name=" + "'" + "select" + '#: QuestionsId #' + "'" + "id=" + "'" + "strue" + '#: QuestionsId #' + "'" + "/>"
},
{
title: "This is true most of the time",
template: "<input class='radioq' type='radio' name=" + "'" + "select" + '#: QuestionsId #' + "'" + "id=" + "'" + "mtrue" + '#: QuestionsId #' + "'" + "/>"
},
{
title: "This is me",
template: "<input class='radioq' type='radio' name=" + "'" + "select" + '#: QuestionsId #' + "'" + "id=" + "'" + "itsme" + '#: QuestionsId #' + "'" + "/>"
}]
});
$("input[type='radio']").on("change", function () {
alert(this.value);
});
});
</script>
Use this : this is to bind event for dynamically generated elements. 使用this:这是为动态生成的元素绑定事件。
$(document).on("change","input[type='radio']", function ()
{
alert(this.value);
});
you should use event delegation for that 您应该为此使用事件委托
$(document).on("change","input[type='radio']", function () {
alert(this.value);
});
Event delegation allows you to attach a single event listener, to a parent element, that will fire for all children matching a selector, whether those children exist now or are added in the future. 事件委托使您可以将单个事件侦听器附加到父元素,该元素将为与选择器匹配的所有子对象触发,无论这些子对象现在存在还是将来添加。
