Shubham Bansal 45 Need Help in calling a apex method from helper in Lightning component.
Hi all I have a strange requirement of calling a helper method in which an apex method is calling, the trick is that I have to call my helper method with a delay of 30 sec.
But in some scenarios before the 30 sec, my component Dom is getting destroyed and in the helper, I face the error of set params of undefined.
I am not sure it is because Dom is destroyed or any other reason.

Hi Shubham,
Please show me your code, I don't understand your issue.
Thank You
I am working on a custom pre-chat form, and the requirement is that when the user enters some text in my subject field of pre-chat field a counter get started which count 30 sec if in between this 30-sec chat is not started then I have to create a record for the entered text in a custom record and if chat is started I have to do nothing.
And My problem is that suppose user to type in the subject field and counter get started then user click on start chat and before 30-sec user leave the chat in this case scope of my component is finish and I got an error setParams of undefined,
I hope you got my requirement.
The piece of code I am facing is:--
handleStartButtonClick: function(cmp, evt, hlp) {
var count=0;
var reqirefield=[];
reqirefield= cmp.get("v.requiredFields");
console.log('@@@@@reqirefield@@@@'+reqirefield);
var prechatFieldComponents = cmp.find("prechatField");
var fields;
console.log('@@@in helper222'+prechatFieldComponents);
// Make an array of field objects for the library
fields = hlp.createFieldsArray(prechatFieldComponents,cmp);
console.log('@@@in fields'+JSON.stringify(fields));
for(var i=0;i<reqirefield.length;i++){
var requireFieldName=reqirefield[i];
for(var j=0;j<fields.length;j++){
if(fields[j].label ==requireFieldName ){
if((fields[j].value=="")||(fields[j].value==" ")){
count++;
}
}
}
}
console.log('@@@MyCount-->'+count);
if(count>0){
cmp.set("v.isError",true);
// location.href="#ttt";
}
else{
// If the pre-chat fields pass validation, start a chat
if(cmp.find("prechatAPI").validateFields(fields).valid) {
cmp.find("prechatAPI").startChat(fields);
console.log('Enter in start chat----->')
cmp.set('v.chatFlag',true);
} else {
console.warn("Prechat fields did not pass validation!");
}
}
}
openArticle : function(component, event, helper) {
var Ide = event.srcElement.id;
component.set('v.Articleid',Ide);
var urlName = component.get("v.OrgURL")+'/'+Ide;
console.log('urlName'+urlName);
var sObectEvent = $A.get("e.force:navigateToURL");
console.log('Ide'+Ide);
sObectEvent .setParams({
"url": urlName
});
sObectEvent.fire();
var sub=component.get('v.Subjectvalue');
var ArtId = component.get('v.Articleid');
window.setTimeout($A.getCallback(function(){
var flg =component.get('v.chatFlag');
console.log('Chat-Flag####Direct',component.get('v.chatFlag'));
if(flg!=true){
flg=false;
}
console.log('Chat-Flag####',flg);
if(flg!=true){
helper.createSearchData(component,sub,ArtId);
}
}), 20000);
}
Helper method:
createSearchData: function(component,sub,ArtId) {
console.log('OpenArticle@@@createSearchData',sub+'3333'+ArtId);
// var subjectdata = component.get('v.Subjectvalue');
// var artid = component.get('v.Articleid');
var subjectdata = sub;
var artid = ArtId;
console.log('OpenArticle@@@subjectdata',component.get('v.prechatFieldComponents'));
console.log('OpenArticle@@@artid',artid);
var call = component.get("c.insertSearchData");
call.setParams({
"SearchTerm":sub,
"ArticleId":ArtId
});
call.setCallback(this, function(response) {
if (response.getState() == "SUCCESS") {
console.log('OpenArticle@@@');
}
});
$A.enqueueAction(call);
}
