Need to restrict a list collector field up to 10 choices in on change

[sumanth1]

Can any one provide the script to restrict the choices to 10 in list collector variable for on change client script.

Hi @sumanth1 ,

 You can use the same script mentioned with On Change:

Hi @sumanth1 ,

Please use this onChange client script, on change field would be the list collector field itself

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }


    var values = g_form.getValue('<list_collector_name>').toString().split(',');

    if (values.length > 10) {

        alert('Limit exceeded - You can select upto 10 values');
        g_form.clearValue('<list_collector_name>');
        for (var i = 0; i < 10; i++) {
            g_form.setValue('<list_collector_name>', values[i]);
        }
        return false;

    }


}

If my answer has helped with your question, please mark it as correct and helpful

Thanks!

Modified this script a little to set the correct number of values needed in the field.

 var reconstructValues = [];
    var curVal = newValue;
    values = curVal.split(",");
    if (values.length > 10) {
        alert('Limit exceeded - You can select upto 10 values only');
        g_form.clearValue('<list_collector_name>');
        for (var i = 0; i < 10; i++) {
            reconstructValues.push(values[i]);
        }
        g_form.setValue('<list_collector_name>', reconstructValues);
    }
