如何完全从函数内部的.forEach内部退出

Question

I have this method:

    wordFormDirty = (): boolean => {
    var self = this;
    angular.forEach(self.word.wordForms, function (wf, key) {
        var wordFormNgForm = 'wordFormNgForm_' + wf.wordFormId
        if (!self[wordFormNgForm].$pristine) {
            return true;
        }
    });
    return false;
};

From what I see this never returns true. Can someone give me advice as to how I can implement this so that a form that's not pristine will make the wordFormDirty() method return true.

Answer 1

If you wish to get a result directly from walking the Array , consider using other methods than forEach . Eg:

return Object.values(this.word.wordForms).some(
  ({ wordFormId }) => !this[`wordFormNgForm_${wordFormId}`].$pristine
);

Answer 2

can you try this, in this case, if I've undestand the issue, the first time there is a value true the result is set to true otherwise it remains false

wordFormDirty = (): boolean => {
    var self = this;
    var result = false;
    angular.forEach(self.word.wordForms, function (wf, key) {
        var wordFormNgForm = 'wordFormNgForm_' + wf.wordFormId
        if (!self[wordFormNgForm].$pristine) {
            result = true;
        }

    });
    return result;
};
