call javascript inside dmf:textarea

Hi All,

I want to add one javascript function inside dmf:textarea in editnote.jsp page in my custom folder........

So I add onchange as below.

<dmf:textarea cols='80' rows='10' name='<%=EditNote.TEXT_AREA_CONTROL_NAME%>' tooltipnlsid="MSG_COMMENT_HEADER" />

replaced with

<dmf:textarea cols='80' rows='10' name='<%=EditNote.TEXT_AREA_CONTROL_NAME%>' tooltipnlsid="MSG_COMMENT_HEADER" onchange='alertfun()' />

<script>

function alertfun(){
alert("Inside Fun");

}

</script>

But my onchange is not calling, means I am not able to call javascript from textarea.

Could you please tell me how can I achieve this one.

Thanks,

Sonu

The WDK standard dmf:textarea does not support an "onchange" attribute that passes through to the HTML rendering layer. The great news is that the WDK fully supports this customization, however it requires advanced knowledge of the WDK framework elements and concepts.

You'll need to:

Write a custom tag/control that extends the standard textarea (custom Java)
Write a custom tld for your tag (xml)
Add a reference to the tld in your jsp (JSP, e.g. mydmf:mytextarea)

I wrote an article a few years back on inserting Javascript into a docbase control for purposes of AJAX. It is different in several ways from your needs (uses custom type, used for only textbox, doesn't use custom tld file, etc..), but it may help you get started.

If you have questions on custom tags/controls/tld/docbase configurations, you'll need to read through the WDK Development Guide.
