Need help with Dropdown list: How to pick values Randoml from dropdown

srini

Hi Narayan,

I have to select dropdown values (Number or String) Randomly. i have written one function but it is not working it is showing null. can you please let me know if any idea.

<browser>
function getRandomLeaveAppId(control)
{
var selectOptions = control.options;

var randomnumber = Math.floor(Math.random() * selectOptions.length);

if(selectOptions.length > randomnumber)
return selectOptions[randomnumber];
else
return -1;
}
</browser>
//_alert(getRandomLeaveAppId(_select("ctl00\$phWorkArea\$ddlStatus")));


function UserLeaveApplication()
{
_alert("test start");
_alert(getRandomLeaveAppId(_select("ctl00\$phWorkArea\$ddlStatus")));
_alert("test end");
}

UserLeaveApplication();

Try changing the return statement from return selectOptions[randomnumber] to return selectOptions[randomnumber].text

It is a good idea to check the value of the random number too, if the above does not work

Hi DP
It is not working...it is not showing alert with selected random value.......

modified return selectOptions[randomnumber] to return selectOptions[randomnumber].text

Execute the below code and let me know what is printed on the console. It prints
(1) the number of items in the control
(2) the generated random number
(3) the return value of getRandomLeaveAppId


<browser>
function getRandomLeaveAppId(control)
{
var selectOptions = control.options;
_debug(selectOptions.length); //print length

var randomnumber = Math.floor(Math.random() * selectOptions.length);
_debug(randomnumber); //print value of random number

if(selectOptions.length > randomnumber)
return selectOptions[randomnumber].text;
else
return -1;
}
</browser>
//_alert(getRandomLeaveAppId(_select("ctl00\$phWorkArea\$ddlStatus")));

function UserLeaveApplication()
{
// _alert("test start");
_debug(getRandomLeaveAppId(_select("ctl00\$phWorkArea\$ddlStatus")));
// _alert("test end");
}

UserLeaveApplication();

Note:

_select("ctl00\$phWorkArea\$ddlStatus") --> in this dropdown list we have "Approved","Cancel" and "Rejected" values.

Ooops....I have no clue. But the above code works for me. Only change that I made is the Id of the control!! Are you sure you do not have any Debug output on the console?
