Oracle Application Express (APEX): Creating an APEX Button to Call JavaScript

Oracle Tips by Burleson Consulting

Creating an APEX Button to Call JavaScript

Now you have setup the code in your application page so that other page items can make calls to the functions defined in the JavaScript.  Letís add the call to the JavaScript code to the Submit button we created earlier.

In previous chapters we covered the creation of a button and how to set properties to branch to another page, set the HTML Request, clear page cache, and set item values.  In those sections the button performed the Submit by default, but in this section we are going to override the default submit behavior of a button and cause it to call our JavaScript.  This is accomplished by editing the button attributes for the Submit button and setting the target URL to the code shown here 


<a href="javascript:validateLogin('P4_USERNAME','P4_PASSWORD');">


Figure X.3 Ė Calling JavaScript from a Button.

Even though you are setting the target to URL you are not entering a traditional looking URL.  Instead you are entering a call to the JavaScript.

M         Your page items will likely have different names than mine so make the necessary changes before saving your changes.

Edit the attributes of the Submit button and enter the text from above in the URL Target text area as shown in Figure X.3.  When the Submit button is clicked it will execute the JavaScript.
