whene select Apples then got id 1and select Oranges then 2.
this is simple kendo dropdown example.

<script>
$("#dropdownlist").kendoDropDownList({
dataSource: [
{ id: 1, name: "Apples" },
{ id: 2, name: "Oranges" }

dataValueField: "id",
index: 1,
select: onSelect
});
function onSelect(e) {
console.log(e);
};
</script>
</body>
thanks.
In order to retrieve the selected Id you can use the dataItem object and access the id within it with change event:
var dataItem = e.sender.dataItem();
$('#id').text(dataItem.id);
This will get you access to any data within the object too:
$('#name').text(dataItem.name);
Working example
http://jsfiddle.net/ygBq8/1/
Html
<input id="dropdownlist" /><br/>
<span id="id" >Id</span><br/>
<span id="name" >Name</span><br/>
JavaScript
$("#dropdownlist").kendoDropDownList({
dataSource: [
{ id: 1, name: "Apples" },
{ id: 2, name: "Oranges" }
],
dataTextField: "name",
dataValueField: "id",
index: 1,
change: onChange
});
function onChange(e) {
var dataItem = e.sender.dataItem();
$('#id').text(dataItem.id);
$('#name').text(dataItem.name);
};
The Select event is a bit more difficult one to use, as that event fires before the item is selected.
If you use the Change event, you should be able to get the dataItem with
this.dataSource.get(this.value())
See sample http://jsbin.com/OcOzIxI/2/edit
Please use this.dataItem()
function onSelect(e) {
alert(this.dataItem().id);
alert(this.dataItem().Name);
};
To select ID of the selected item use:
$("#dropdownlist").val()
And to select TEXT of the selected item use:
$("#dropdownlist").data("kendoDropDownList").text()

I am working on an SPA application where I have a list of data variables that are used as the <option> tags in the dropdown. I want to navigate to another page on the #change event of the dropdown therefore I want to use either the id or name of the select command as the name of the data property. Here is what I mean:
Here is what I have in the data function:
data(){
return {
participants: [
{ value: 0, linkText: '', linkTerm: 'Select' },
{ value: 1, linkText: '/meetings/participants/create', linkTerm: 'Add New' },
{ value: 2, linkText: '/meetings/participants', linkTerm: 'All Participants' },
],
positions: [
{ value: 0, linkText: '', linkTerm: 'Select' },
{ value: 1, linkText: '/meetings/positions/create', linkTerm: 'Add New' },
{ value: 2, linkText: '/meetings/positions', linkTerm: 'All Positions' },
],
}
}
Here is the select tag where I use the above data variables as the <option> tag:
<select name="participants" id="participants" class="select-field" #change="changeRoute($event)">
<option v-for="p in participants" :value="p.value">{{ p.linkTerm }}</option>
</select>
Now I want to have one function changeRoute($event) from which I will navigate to different pages, therefore I want to use the id or name value as the data property, here is the function:
methods:{
changeRoute($event){
var name = $event.target.name;
var value = document.getElementById($event.target.id).value;
}
}
Here in the above function I want to use the name as the data property as below:
I want to write this:
this.name[value].linkText;
And because name here is the name of the tag which is actually participants so the above line of code should mean something like this:
this.participants[value].linkText
And that should return the linkText of the participants object of the data function.
Any help is appreciated in advance.
Change the below line
this.name[value].linkText;
to
this[name][value].linkText;
I have a BootstrapTable select box. I know you can use a function to populate the values in the select box. I'd like that function to change which array it provides based on the value of a second column (called Text_example).
So in my example, if Text_example for that row is 1, the select box should have the following data: [{1:1}]. if Text_example for that row is 2, the select box should have the following data: [{2:2}]
I think my problem is that I don't know how to pass just the row's data to the function get_values as my method seems not to be working.
Full Fiddle: http://jsfiddle.net/goxe6ehg/
var data = [{"Text_example": 1},{"Text_example": 2}];
function get_values(data) {
if (data['Text_Example'] === 1) {
return [{1:1}];
}
else {
return [{2: 2}]
}
}
$('#table').bootstrapTable({
columns: [
{
field: 'Select_example',
title: 'Select_example',
editable: {
type: 'select',
source: get_values($('#table').bootstrapTable('getData'))
}
},
{
field: 'Text_example',
title: 'Text_example'
}
],
data: data
});
EDIT: I over-simplified my example. Rather than having a static field for text_example I need it to be a select box, where the value for select_example changes based on what the user has selected in text_example.
Updated JSFiddle: http://jsfiddle.net/4wwv18Lq/4/
You can use the oninit handler on the bootstraptable library.And add the editables by iterating through the data object.
var data = [{"Text_example": 1},{"Text_example": 2}];
$('#table').on('editable-init.bs.table', function(e){
var $els = $('#table').find('.editable');
$els.each(function(index,value){
$(this).editable('option', 'source', data[index])
});
});
$('#table').bootstrapTable({
columns: [
{
field: 'Select_example',
title: 'Select_example',
editable: {
type: 'select'
}
},
{
field: 'Text_example',
title: 'Text_example'
}
],
data: data
});

I'm trying to disable the selected option in select2 but it seems like the select2 is not refreshing.
My purpose is to disable each item in the select2 list after selecting it. I see the HTML that the option got the disabled attribute but the option is still enabled in the select2 element.
$("#select-filter").select2({
placeholder: "Select a category",
data:[{
id: "",
text: ""
},{
id: "project",
text: "project"
},{
id: "date",
text: "date"
},{
id: "user",
text: "user"
}]
}).on("change", function(e) {
$("#select-filter :selected").attr("disabled", "true");
});
See example : https://jsfiddle.net/bkqeqbay/1/
You can use the select event and the data like so:
...}).on("select2:select", function(e) {
console.dir(e.params.data);
e.params.data.disabled = true;
});
Updated fiddle: https://jsfiddle.net/bkqeqbay/4/
Note that if you must also disable the underlying select element option you can do:
var index = $(e.params.data.element).index();
$("#select-filter").find('option').eq(index).prop('disabled',true);
I use Webix 2.5.14. There was a problem with a component Richselect.
In this form there is a richselect with options.
webix.ui({
view: "form",
id:"addAccessForm",
borderless: true,
elements: [
{
view: "richselect",
id:"rule",
label: 'Rule',
value:1,
options:[
{id:1,value:"R"},
{id:2,value:"W"},
{id:3,value:"RW"},
{id:4,value:"RW+"}
]
},
....
]
});
I click on the button and opens a form for editing, and I need to select an element in the richselect area, for example with id = 3.
How to do it? setValue () adds a new one (element), but doesn't select what i need.
You need to use
$$("rule").setValue(3); // 3 - id of record
It is a bit counterintuitive, but you need to use the "id" of record in the setValue command, not the value.
See my example:
webix.ui({
view: "form",
id:"addAccessForm",
borderless: true,
elements: [
{
view: "richselect",
id:"rule",
label: 'Rule',
value:1,
options:[
{id:1,value:"R"},
{id:2,value:"W"},
{id:3,value:"RW"},
{id:4,value:"RW+"}
]
},
{ view:"button", value: "Select Value", click:function(){
$$("rule").setValue(2);
}}
]
});

I am trying Kendo multiselect demo.
var multi = $("#multiselect").kendoMultiSelect({
dataSource: [
{ id: 1, name: "Apples" },
{ id: 2, name: "Oranges" }
],
dataTextField: "name",
dataValueField: "id",
}).data("kendoMultiSelect");
In them I want to set option element attribute selected if value = "2".
like $('option[value=2]').attr('selected','selected');
Any idea how I can do this?
add an databound event to multiselect
function MultiSelectDataBound()
{
var multiSelect = $("#multiselect").data("kendoMultiSelect"),
multiSelect.dataSource.filter({}); //clear applied filter before setting value
multiSelect.value(2);
}
Or you can create a text box and button add an clicked event and get values from text box
function btnClicked()
{
var multiSelect = $("#multiselect").data("kendoMultiSelect"),
multiSelect.value($("#textbox").val().split(","));
}
