In my pop up search when my select returns zero records, I want to show the alert message and if its searching for existing records I want show the different alert message too. I added the error condition in Controller method but its not working, please help.
**Lightning Component**
<div onkeyup="{!c.handleKeyUp}">
<lightning:input aura:id="enter-search" name="enter-search" label="Search for Existing Customer Records" type="search" value="{!v.queryterm}"
placeholder ="Search using First Name or Last Name or EmailAddress!" isLoading="{!v.issearching}"/>
</div>
**Controller**
handleKeyUp: function (component, event, helper) {
if (event.which == 13){
component.set('v.issearching', true);
setTimeout(function() {
var queryTerm = component.find('enter-search').get('v.value');
helper.getCustomerRecords(component,queryTerm);
component.set('v.issearching', false);
}, 1000);
} else if(state == "ERROR"){
var errors = response.getError();
component.set("v.showErrors",true);
component.set("v.errorMessage",errors[0].message);
}
}
**Helper**
getCustomerRecords : function(component, queryTerm) {
var action = component.get("c.searchCustomer");
action.setParams({
"searchstring": queryTerm
});
var selected = [];
var records = component.get("v.selectedCustomerData");
records.forEach(function(record){
selected.push(record.Id);
});
action.setCallback(this, function(response) {
var state = response.getState();
if (state === "SUCCESS") {
var returnrecords = response.getReturnValue();
var mergedrecords = [];
returnrecords.forEach(function(returnrecord){
if(!selected.includes(returnrecord.Id)){
mergedrecords.push(returnrecord);
}
});
mergedrecords = mergedrecords.concat(records);
component.set("v.customerData",mergedrecords);
component.set("v.selectedCustomerKey",selected);
}
else {
console.log("Failed with state: " + state);
}
});
$A.enqueueAction(action);
}```
