Clients script or any script onchange any variables

[rolodo]

I have a script that I need to run on many variables on change.

does servicenow provide a way to do it.

here's an example :

include script to get the variables, orders and names

var Variable_Indentifier = Class.create();
Variable_Indentifier.prototype = Object.extendsObject(AbstractAjaxProcessor, {
   isnotinvariableset : function() {
   var catItem = this.getParameter('sysparm_cat_item_sysid');
   var gr = new GlideRecord('item_option_new');
   gr.addQuery('cat_item', catItem);
   gr.query();
   var variables = new Array();
   while(gr.next()){
   var myvar = {sys_id:gr.sys_id.toString(), name:gr.name.toString(), order:gr.order.toString()};
   variables.push(myvar);
   }
   return (JSON.stringify(variables));
   }
});

client script to get what variable to reset from the include script

function onLoad() {
     //Type appropriate comment here, and begin script below
     var gaValid = new GlideAjax('Variable_Indentifier');
   gaValid.addParam('sysparm_name','isnotinvariableset');
   gaValid.addParam('sysparm_cat_item_sysid',$('sysparm_id').value);
   gaValid.getXMLWait();
   answer = gaValid.getAnswer();
   window.toreset = JSON.parse(answer);
   console.log("-----------------------------------------"+window.toreset[0].order);
}

and the script that trigger on edit of some variables that reset all other variables under it :

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
   return;
   }
   //need the client script : Find variables to reset
   if(window.toreset != null){
   var myorder = findOrder(control);
   var myname = findName(control);
   //window.toreset.length
   console.log(window.toreset[56].name)
   for(i = 0; i < window.toreset.length; i++){
   if(window.toreset[i].name != myname && window.toreset[i].order >= myorder && window.toreset[i].name != 'ba_select_location' && window.toreset[i].name != 'ba_ipPhone_display_name')
   {
   g_form.setValue(window.toreset[i].name.toString(), '');
   }
   }
   }
}

function findOrder(control)
{
   var myorder = 0;
   for(i = 0; i< window.toreset.length; i++){
   if(window.toreset[i].sys_id == control.name.substring(3, 35)){
   myorder = (window.toreset[i].order);
   }
   }
   return myorder;
}

function findName(control)
{
   var myname = 0;
   for(i = 0; i< window.toreset.length; i++){
   if(window.toreset[i].sys_id == control.name.substring(3, 35)){
   myname = (window.toreset[i].name);
   }
   }
   return myname;
}

first, onload I get all the variables of my item

and after if I change a variables that influence something under it I trigger the script that clean (set varaible to '')
for now it trigger onchange of these variables so I have many client script

I would like to have only one script that will do this
(I'm thinking to use a onload script with some EventListener)

Thanks, I speak french so sorry for my bad english

Hi David,

Vous ne pouvez pas faire cela dans un script client et des besoins multiples script client onchange
