TextBox JSP Tag Overview
The TextBox JSP tag is a server-side wrapper for the Kendo UI TextBox widget.
The Kendo UI TextBox widget converts an <input> element into a styled input.
The TextBox is part of Telerik UI for JSP, a
professional grade UI library with 90+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.
Getting Started
Configuration
The TextBox provides a set of default API configuration options that can be set during its initialization such as value, placeholder, and so on. Below are listed the steps for you to follow when configuring the Kendo UI TextBox.
Step 1 Make sure you followed all the steps from the introductory article on Telerik UI for JSP.
Step 2 Create a new action method which renders the view.
@RequestMapping(value = {"/", "/index"}, method = RequestMethod.GET)
public String index() {
return "textbox/index";
}
Step 3 Add the Kendo UI taglib mapping to the page.
<%@taglib prefix="kendo" uri="https://www.telerik.com/kendo-ui/jsp/tags"%>
Step 4 Add a TextBox tag.
<kendo:textBox name="textbox" placeholder="Name..." style="width: 100%;"></kendo:textBox>
Labels
The Label enables you to associate a label HTML element with a TextBox.
The example below demonstrates how to add a floating label to a TextBox.
<kendo:textBox name="textbox">
<kendo:textBox-label content="Name" floating="true"></kendo:textBox-label>
</kendo:textBox>
<style>
.k-floating-label-container {
width: 100%;
}
</style>
Event Handling
Subscribe to Events
You can subscribe to the change event by the handler name. The change fires each time a new value is set by the user. For a full list, refer to the TextBox events documentation in the API section.
Important: The
changeevent is not fired when the value of the widget is changed from JavaScript code.
<kendo:textBox name="textbox" change="onChange" style="width: 100%;"></kendo:textBox>
<script>
function onChange() {
console.log("Change :: " + this.value());
}
</script>
Reference
Existing Instances
To reference to an existing TextBox instance, use the jQuery.data() method. Once a reference is established, use the API to control its behavior.
The following example demonstrates how to access an existing TextBox instance.
//Put this after your Kendo TextBox tag declaration
<script>
$(function() {
// Notice that the Name() of the TextBox is used to get its client-side instance
var textbox = $("#textbox").data("kendoTextBox");
});
</script>
