Need Help Returning Values with GlideAjax

[codechaser]

I need to populate a dropdown of courses, based-on the term selected. I have a GlideAjax call to fetch the data and then use the addOption() function to populate the value in the 'u_course' field.   However, I am unable to filer courses offered by 'u_term_code'... The same list of courses is populated, regardless of term selected.

What am I missing?

Client Script:

function onChange(control, oldValue, newValue, isLoading) {

if (isLoading || newValue == '') {

return;    

}  

var ga = new GlideAjax('GetListValue');

ga.addParam('sysparm_name','getList');

ga.addParam('sysparm_term ', newValue);

ga.getXML(fillDetails);

function fillDetails(serverResponse){

var answer = serverResponse.responseXML.documentElement.getAttribute("answer");

var choiceval = answer.split(',');

for(var i = 0; choiceval.length > i ; i++){

g_form.addOption('u_course', choiceval[i], choiceval[i], [i]);

}

}

}

Client Callable Script Include:

var GetListValue = Class.create();

GetListValue.prototype = Object.extendsObject(AbstractAjaxProcessor, {

getList : function() {

var courses = [];

var gr = new GlideRecord('u_bsu_courses');

gr.addQuery('u_term_code', this.getParameter('sysparm_term'));

gr.query();

while(gr.next())

courses.push(gr.name.toString());

return courses;

},

type: 'GetListValue'

});

Looks similar to a subcategory field where Term is the category. Are you getting a response now?

This like doesn't look right: for(var i = 0; choiceval.length > i ; i++){

Try this: for(var i = 0; i < subcats.length; i++) {

Hi Michael and thank you for the reply.   I made the change you suggested, above and am still returning all courses, no matter which term is selected.

Ok, try changing this line:

ga.addParam('sysparm_term ', newValue);

to

ga.addParam('sysparm_term ', g_form.getValue('u_term'));

where u_term is the name of your field.

Thank you for the suggestion.   Unfortunately, that did not work, either.   I also tried ga.addParam('sysparm_term ', 'u_term_code'); with no result.
