Issue
I have a reactive form and I am using Material Angular, with a tab group and the tab names comes from an array, I need to add the possibility of changing those tabs names for new ones. If a write a new title in the input I need to update the name of the tab label.
I’m getting the value from the input, but I can’t figure it out how to send it to the names of the tabs:
app.component.ts
this.newTitleArm = selection.formdata.titleTextArms;
console.log(this.newTitleArm);
Solution
Can you have a look at this Stackblits
Note that I have modified the submit method and have added
if(this.form.get('titleArms').value === 'changeArm'){
this.tabs[this.selected.value].name = this.form.get('titleTextArms').value;
}
Here I'm assigning the titleTextArms control value to selected tab name. You can get selected tab by this.tabs[this.selected.value]
Also added the if condition to check selection of radio button.
UPDATE:
since you have used tab names to create the text in the parent component.
In the submit method
need to do the tab name update before emitting the updateDataEvent.
submit(): void {
if (this.form.get('titleArms').value === 'changeArm') {
if (this.form.get('titleTextArms').value !== '') {
this.tabs[this.selected.value].name =
this.form.get('titleTextArms').value;
}
}
this.updateDataEvent.emit({
formdata: this.form.getRawValue(),
tabs: this.tabs,
});
}
