问题
这是您要翻译的代码部分：
Hi I have a line in angular I cant for the life of me figure out whats not working. My friend asked for help with this as the errors causing data to not display but im not sure where the problem is at.
Error Message:
this.ccavtabSelected.nativeElement.classlist.contains(...).focus is not a function
@ViewChild('ccavTabSelected') ccavTabSelected: ElemenRef (this is where the ccavtab variable is set)
full line that is not working:
setTimeout()) => {
this.ccavtabSelected.nativeElement.classlist.contains('ccav-tab-container-selected active').focus();
}, 20);
Code for the entire function:
selectTab(tabIndex: any) {
try {
// To do
if (event.currentTarget['parentElement'].getElementsByClassName('active').length > 0) {
event.currentTarget['parentElement'].getElementsByClassName('active')[0].classList.remove('active');
}
if (tabIndex == TabCategory.ACCOUNTSUMMARY) {
event.currentTarget['classList'].add('active');
setTimeout(() => {
if (this.ccavTabSelected.nativeElement.classlist.contains('ccav-tab-container-selected active')) {
this.ccavTabSelected.nativeElement.focus();
}
}, 20);
console.log(this.ccavTabSelected.nativeElement.classList)
this.isAccountSummaryActive = true;
this.isDebitcardActive = false;
this.isMerchantServicesActive = false;
if (!this.changeDetectorRef['destroyed']) {
this.changeDetectorRef.detectChanges();
}
this.accSummaryCommonService.updateTabInContext(TabCategory.ACCOUNTSUMMARY);
} else if (tabIndex == TabCategory.DEBITCARD) {
event.currentTarget['classList'].add('active');
setTimeout(() => {
this.ccavTabSelected.nativeElement.classList.contains('ccav-tab-container-selected active').focus();
}, 20);
this.isAccountSummaryActive = false;
this.isDebitcardActive = true;
this.isMerchantServicesActive = false;
if (!this.changeDetectorRef['destroyed']) {
this.changeDetectorRef.detectChanges();
}
this.accSummaryCommonService.updateTabInContext(TabCategory.DEBITCARD);
}
else if (tabIndex == TabCategory.MERCHANTSERVICES) {
event.currentTarget['classList'].add('active');
setTimeout(() => {
this.ccavTabSelected.nativeElement.classList.contains('ccav-tab-container-selected active').focus();
}, 20);
this.isAccountSummaryActive = false;
this.isDebitcardActive = false;
this.isMerchantServicesActive = true;
if (!this.changeDetectorRef['destroyed']) {
this.changeDetectorRef.detectChanges();
}
this.accSummaryCommonService.updateTabInContext(TabCategory.MERCHANTSERVICES);
}
this.changeDetectorRef.markForCheck();
} catch (err) {
this.handleErrorMessage("selectTab()", err.message);
}
}

"As stated, it is not a function since contains returns a boolean.
Instead try:
setTimeout(() => {
if (this.ccavtabSelected.nativeElement.classList.contains('ccav-tab-container-selected active')) {
this.ccavtabSelected.nativeElement.focus();
}
}, 20);
```"

As stated, it is not a function since `contains` returns a boolean.
Instead try:
setTimeout()) = > {
if (this.ccavtabSelected.nativeElement.classlist.contains('ccav-tab-container-selected active')) {
this.ccavtabSelected.nativeElement.focus();
}
}, 20);
