Tips for accessing the return value from a method outside of its containing function

Having recently started using Angular, I'm encountering an issue with retrieving a return value from a function that I have implemented within another one.

private validateKeyterm(): boolean {
        const val = this.form.value.term;      
        if (this.selectedTermType == 'keywords') {
            // filter out data
            this.keywordTemp.filter(function (d) {
              if((d.term.toString().indexOf(val) !== -1 || !val) == true){
                    console.log("keytemp: true");
                    return true;
                }
             
            }) ;
        } else {
            this.profanityTemp.filter(function (d) {
                if((d.term.toString().indexOf(val) !== -1 || !val) == true){
                    console.log("profanity: true");
                    console.log("true");
                    return true;
                }
                else{ return null;}

            });
        }
        console.log("false");
        return false;
    }
 

Unfortunately, I keep receiving the return value "fail" consistently when executing this function. Can anyone assist me in finding a solution to ensure that the "validateKeyterm" function accurately returns "true" in certain cases?

Answer №1

To determine the correct values for the function you are working on, a deeper look at the code is necessary. However, based on the provided code snippet, my recommendation would be to utilize arrow functions within the filter function as shown below:

  private validateKeyterm(): boolean {
    const val = this.form.value.term;      
    if (this.selectedTermType == 'keywords') {
        // filter out data
        return !!(this.keywordTemp.filter(d => {
          if((d.term.toString().indexOf(val) !== -1 || !val) == true){
                console.log("keytemp: true");
                return true;
            }
         
        }));
    } else {
        return (this.profanityTemp.filter( d => {
            if((d.term.toString().indexOf(val) !== -1 || !val) == true){
                console.log("profanity: true");
                console.log("true");
                return true;
            }
            else{ return null;}

        }));
    }
    console.log("false");
    return false;
}
