- |
showCloseBtn |
boolean | false | Whether to display the close button. | - |
value |
string | - | Set a default value for this control | - |
label |

name |
string | - | Name is not deprecated when used with form fields. | - |
placeholder |
string | - | Specifies a short hint that describes. | - |
disabled |
boolean | false | Whether it is disabled | - |
required |
boolean | false | When present, it specifies that a field must be filled out before submitting the form. | - |
onFetch |
function | - | Call a function when data is successfully fetched. It returns one callback value which is the fetched data (Array) | - |
fetchArray |
array | - | Set multiple requests, it should be an array | - |
onChange |
function | - | Call a function when the value of an HTML element is changed. It returns six callback values.
|
- |
onBlur |
function | - | Call a function when a user leaves a form field. It returns only one callback value which is the Control Event (Event) | - |
onFocus |
function | - | Call a function when an form field gets focus. It returns only one callback value which is the Control Event (Event) | - |
Array configuration properties of the fetchArray:
| Property | Type | Default | Description | Required |
|---|---|---|---|---|
fetchFuncAsync |
Constructor | - | A method as a string from the constructor. | - |
fetchFuncMethod |
string | - | When the property is true, every time the select changes, a data request will be triggered. The methord must be a Promise Object. |
- |
fetchFuncMethodParams |
array | - | The parameter passed by the method, it is an array. Note: the first element is a query string, the second element is the number of queried data (usually a number), and then you can increase the third, or fourth, and more parameters. Such as ['',0], ['',99,'string 1','string 2'], ['',0,'$QUERY_ID'] There should be at least one parameter which is the query string. |
- |
fetchCallback |
function | - | Return value from fetchCallback property to format the data of the API callback, which will match the data structure of the component. At the same time it returns the original data, you will use this function and use the return keyword to return a new value. |
- |
hierarchical |
boolean | false | Set hierarchical categories ( with sub-categories ) to attribute options. |
- |
indentation |
string | - | Set hierarchical indentation placeholders, valid when the hierarchical is true. |
- |
doubleIndent |
boolean | false | Set double indent effect, valid when the hierarchical is true. |
- |
A successful response returns the details of the callback such as Sample Request Body:
Among them, id, queryId, name and label are attributes used by the system, and other attributes can be added freely.
labelusually uses hierarchical style. (It takes effect when thehierarchicalattribute is configured infetchArray)
The "name" attribute supports HTML tags
[
{
"id": 1,
"queryId": 1,
"name": "Text 1",
"customAttr1": "a1"
},
{
"id": 2,
"queryId": 1,
"name": "Text 1_2",
"customAttr1": "a1"
},
...
]You need to use a fetchCallback property to format the data of the API callback, which will match the data structure of the component.
