Show Hints for choice lists

This could be interesting...

A stakeholder asked me to show hints in a more obvious way on a form. This was my suggestion. Using the hint field on the sys_choice table. Have a client script onChange check for the value, if one is set, clear the message for this field, and show the found message.

//script include global.choiceUtil
//client callable true
var choiceUtil = Class.create();
choiceUtil.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getHint: function() {
try {
var returnObj = {};
var hint = new GlideRecord('sys_choice');
hint.addQuery('name', this.getParameter('sysparm_table'));
hint.addQuery('element', this.getParameter('sysparm_field'));
hint.addQuery('value', this.getParameter('sysparm_val'));
hint.addQuery('inactive', 'false');
hint.query();
if (hint.next()) {
returnObj.hint = hint.getValue('hint');
} else {
returnObj.error = 'no choice found for ';
returnObj.error += hint.getEncodedQuery();
}
//returnObj.query = hint.getEncodedQuery();
return JSON.stringify(returnObj);
} catch (error) {
return JSON.stringify(error, '', ' ');
}
},
type: 'choiceUtil'
});
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var field = 'state';

var ga = new GlideAjax('global.choiceUtil');
ga.addParam('sysparm_name', 'getHint');
ga.addParam('sysparm_table', g_form.getTableName());
ga.addParam('sysparm_field', field);
ga.addParam('sysparm_val', newValue);
ga.getXML(HintParse);

function HintParse(response) {
var answer = JSON.parse(response.responseXML.documentElement.getAttribute("answer"));
g_form.hideFieldMsg(field, true);
if (answer.hint) {
g_form.showFieldMsg(field, answer.hint, 'info', true);
}
}

}
