GlideAjax query

[J_31]

Hi 

I am not sure why the value is not populated when I change the configuration item field value in Incident form . it updates when is save. Its suppose to update when I change the value in CI field.

Script Include

--------------------

var PopulateDemo = Class.create();
PopulateDemo.prototype = Object.extendsObject(AbstractAjaxProcessor, {

popAssignmentGroup : function()
{
var gr = new GlideRecord('cmdb_ci');
gr.addQuery('sys_id',this.getParameter('sysparm_cmdb_ci'));
gr.query();
if(gr.next())
{
return gr.support_group;
}
},

type: 'PopulateDemo'
});

Client Script

-----------------

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var ga = new GlideAjax('PopulateDemo');
ga.addParam('sysparam_name','popAssignmentGroup');
ga.addParam('sysparam_cmdb_ci',g_form.getValue('cmdb_ci'));
ga.getXML(getResponse);

function getResponse(response)
{
var answer = response.responseXML.documentElement.getAttribute("answer");
g_form.setValue('assignment_group',answer);
}

//Type appropriate comment here, and begin script below

}

I would assume the client script runs on the field cmdb_ci? 

Try replacing this line:

ga.addParam('sysparam_cmdb_ci',g_form.getValue('cmdb_ci'));

with:

ga.addParam('sysparm_cmdb_ci', newValue);

Also, in your script include, try making it a habbit always to use .getValue(), so:

return gr.getValue('support_group');

[J_31]

ga.addParam('sysparam_cmdb_ci', newValue);

New Value may not be the value entered in CMDB_ci field, what if it takes caller information if I enter that in another field.

if you configured, client script on-change of other fields. You have to use the

g_form.getValue('cmdb_ci');  // it will run this script and populate assignment group when that field value changed.

I would suggest to create client script on-change of cmdb_ci field.

Thanks!

Well, if you do run it on the client script on the cmdb_ci field, then the getValue will retrieve the stored value on the form, not the new one, thus newValue is correct. I don't see the use case for doing this on change of Caller_id, since the cmdb_ci should have not relation to the caller, and you are setting the assignment group based on the cmdb_ci field.
