在下文中一共展示了isNumber函數的4個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的TypeScript代碼示例。
示例1: get
Object.keys(sources).reduce<DetailItem[]>((accumulator, source) => {
const item = get(source, sources);
if (Array.isArray(item) || isString(item) || isNumber(item)) {
const field = path ? `${path}.${source}` : source;
category = field.split('.')[0];
if (isEmpty(category) && baseCategoryFields.includes(category)) {
category = 'base';
}
return [
...accumulator,
{
category,
field,
values: item,
originalValue: item,
} as DetailItem,
];
} else if (isObject(item)) {
return [
...accumulator,
...getDataFromHits(item, category || source, path ? `${path}.${source}` : source),
];
}
return accumulator;
}, []);示例2: parseFloat
const convertToNumber = (value: object | number | boolean | string): number => {
if (isNumber(value)) {
return value;
} else if (isString(value)) {
return parseFloat(value);
} else {
return NaN;
}
};示例3: if
export const parseQueryValue = (
value: string | number | object | undefined | null
): string | number => {
if (value == null) {
return '';
} else if (isObject(value)) {
return JSON.stringify(value);
} else if (isNumber(value)) {
return value;
}
return value.toString();
};示例4: GraphQLScalarType
* serialize: gets invoked when serializing the result to send it back to a client.
*
* parseValue: gets invoked to parse client input that was passed through variables.
*
* parseLiteral: gets invoked to parse client input that was passed inline in the query.
