Yes Ajai, I understood your requirement.
You can write onChange script on Listcollector variable.
try this script:
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var gr = newValue.split(',');
if(gr.length>2){
g_form.showFieldMsg('avl_grp','you have selected more than 2','error');
}
//Type appropriate comment here, and begin script below
}
The link you provided, i am aware of it.
I tried with the code you mentioned and its not working properly it seems.
I need to display an alert message instead of the field message here.
If the allowed length is 5 then it will through the alert and accept the sixth value also. So I tried by giving the length as 4 and so it only allowed to select 5 options now.
But when you try selecting the same option 2 times then its added to the right bucket. That is when you select the fist time it gives the error and the second time it gives error and then add the value to right bucket.
current script:
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
//Limit the number of selected options in a list collector
var gr = newValue.split(',');
if(gr.length> 4){
//g_form.showFieldMsg('groups','You cannot select more than 5 options.','error');
alert('You cannot select more than 5 options.');
}
}
