Hi,
In this case you can write onChange client script on string field.
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var ga = new GlideAjax('checkChoiceValues');
ga.addParam('sysparm_name','getDetails');
ga.addParam('sysparm_choiceVal',newValue); //newValue will requester for
ga.getXML(callback);
function callback(response)
{
var answer = response.responseXML.documentElement.getAttribute("answer");
if(answer==true||answer=='true'){
alert("choice already present");
}
}
}
Create script include
Script include name - checkChoiceValues
client callable - true
var checkChoiceValues = Class.create();
checkChoiceValues.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getDetails :function(){
var choiceVal=this.getParameter('sysparm_choiceVal');
var gr=new GlideRecord('sys_choice');
gr.addQuery('value',choiceVal);
gr.query();
if(gr.next())
{
return true;
}
else{
return false;
}
},
type: 'checkChoiceValues'
});
Thanks,
