QRCode JSP Tag Overview
The QRCode JSP tag is a server-side wrapper for the Kendo UI QRCode widget.
Getting Started
Configuration
Below are listed the steps for you to follow when configuring the Kendo UI QRCode.
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 to render the view.
@RequestMapping(value = {"/", "/index"}, method = RequestMethod.GET)
public String index() {
return "/dataviz/qrcode/index";
}
Step 3 Add a qrcode tag.
<kendo:qRCode name="qrcode" value="foo" >
</kendo:qRCode>
Step 4 Choose the appropriate error correction level and encoding.
<kendo:qRCode name="qrcode" value="foo" errorCorrection="H" encoding="UTF_8" >
</kendo:qRCode>
Reference
Existing Instances
You are able to reference an existing QRCode instance via jQuery.data(). Once a reference is established, you are able to use the QRCode API to control its behavior.
//Put this after your Kendo QRCode tag
<script>
$(function() {
// Notice that the name of the qrcode is used to get its client-side instance
var qrcode = $("#qrcode").data("kendoQRCode");
qrcode.value("bar");
});
</script>
