Hi Antony,
These scripts will get you there, but you could be welcoming trouble due to the ability to edit and delete rows - so user actions could cause the row numbers to appear out of order. You can make this variable read-only and resort the MRVS or re-number the Row variable onSubmit if that's an issue.
First, if you're using Service Portal, you'll need an onLoad Catalog Client Script that Applies to the Catalog Item, not within the MRVS.
function onLoad() {
if (this) {//we only need to do this for Service Portal
//We need to make the g_form object for the parent item available from the MRVS window
this.cat_g_form = g_form;
}
}
Next, an onLoad Catalog Client Script that Applies to the Variable Set:
function onLoad() {
var mrvs = '';
if (this) { //Service Portal method
mrvs = this.cat_g_form.getValue('mrvs1');//internal name of your MRVS
}
else { //native UI method
mrvs = parent.g_form.getValue('mrvs1');
}
if (mrvs.length > 2) { //native UI returns [] for empty MRVS value
var obj = JSON.parse(mrvs);
g_form.setValue('v_row', parseInt(obj[obj.length-1].v_row) + 1); //your variable name
}
else {
g_form.setValue('v_row', '1');
}
}
