Calling javascript function from CustomHML

Hi,

I have a coach, where there is a CustomHTML  control which contains a script tag and a javascript function defined.

How I can call that function from a button defined in the same coach screen? That is, how to configure the button “on click” event to call the javascript function.

Thanks, Jairo

Hi Jairo,

You should be able to call the function from the On Click event, such as

myAlert();

which calls:

Hi Stephen,

Thanks for your response.

I'm trying the way you described. I have a Coach with 2 controls

** CustomHTML

** Button

CustomHTML code is:

<h3>Generate Random</h3>
<script>
function generateRandom() {
var val = Math.floor(Math.random() * 100);
// debugger statement
debugger;
Alert(“New value is “ + val);
//# sourceURL=neil.js
};
</script>

Button On-click event: generateRandom();

The response I get on the browser debug screen is that generateRandom() function is not defined.
There is an article that suggest it must be called as @generateRandom() but I think that worked for a previous version
See the attached file.
Thanks, Jairo

Hi Jairo,

There were two error in your script that once corrected executed correctly.

First, alert() is case sensitive and should not be capitalized.

Second, your quotes for “New value is ” need to be straight quotes, and not curly quotes like “ and ” .
