异步 Do While 循环

Question

I need to pull data from an API, but it sends me the data in pages of 100 + the total count of results. The way I tried doing is

let count, page = 0;
do {
    ++page
    pullData(page, () => {
        count = data.count
    });
} while (page < count / 100);

but the code checks the condition of the loop before count is initialized (page < undefined / 100), and the loop ends up running only the first time.

Is there a way to make the loop wait for the async body to run before checking the condition?

Answer 1

Use async/await or recursive functions like this:

const recursive = (page) => {
    pullData(page, () => {
        count = data.count;
        if (page < count / 100) {
            recursive(++page)
        }
    })
}
