How can I put in variable response from service and then display it on hover? I tried this:
toolTip: string;
async mouseover(params) {
this.handle = setTimeout(() => {
this.toolTip = this.checkSaldo(10, 'FRA');
this.show = true;
}, 4000);
}
checkSaldo(amount: any, currencyCode: any): Promise<string> {
return new Promise((resolve) => {
this.restService.getByParam('recalculatedSaldo', { amount: amount, currency: currencyCode }).subscribe(response => {
resolve(response.payload);
});
})
}
but I'm getting an error on toolTip
variable:
Type 'Promise' is not assignable to type 'string'
Any suggestion?
CodePudding user response:
You can't assign the Promise
into a string
field.
But, you need to wait the Promise callback and assign the value as below:
this.checkSaldo(10, 'FRA').then((x) => {
this.toolTip = x;
...
});
