Get the return value from a function in javascript

[ashishc]

Hi
I want to know how can I get the return value from a function into a variable onClick event of a selection of radio button.

Let me explain in detail, I have 3 radio buttons and if i select any one, then I want to call a function to which I pass the value of selected radio button and the function does some processing and then returns some value which i store in a variable.

[CODE=javascript]var returnValue="";
formatButton = "<input type='radio' onClick='return getValue()' value='Radio2' name='btn2'>"

function getValue()
{
return "selected button is 2";
}
[/CODE]
Please let me know how to do this?

Thanks
Ashish

hi ...

that is very basic and simple have a look at the following example:

[CODE=javascript]// declare a variable:
var a = '';

// declare a function that returns a passed value
function myfunc(param) {
return param;
}

// to assign the returnvalue use:
a = myfunc('test');

// now we alert a that has 'test' assigned
alert(a);
[/CODE]
kind regards

That is not what I want..I can do that too but what I want is when i select a radio button, it invokes the onClick event. Now onClick of radio button I want a function invoked which returns a value and that is stored in a variable.

that is the same:

[HTML]<input type="radio" onclick="var ret_val = getValue();" value="Radio2" name="btn2">
[/HTML]
this assigns the return-value that the function getValue() returns to a global variable called ret_val

kind regards
