我正在努力嘗試將流合併爲一個流,並在h1中顯示文本。爲什麼我無法在cyclejs中使用xstream合併流?
但是不能夠使它發揮作用:
這是我的代碼:
function main(sources) {
// single streams
let letter$ = xs.of({text: 'abcd'});
let number$ = xs.of({text: '123456'});
//try to combine them into one
const combined$ =
xs.combine(letter$, number$).
map(([ letter, number ]) => {
return { text: letter.text + ' ' + number.text };
});
//updates the virtual dom with the reponse
const vdom$ = combined$
.map(o => o.text)
.startWith('Loading...')
.map(text =>
div('.container', [
h1(text)
])
);
return {
DOM: vdom$
};
}
它顯示錯誤說:
index.js:6 TypeError: f is not a function
at invoke (core.js:36)
at CombineListener._n (core.js:72)
at Stream._n (core.js:886)
at FromArrayProducer._start (core.js:142)
at Stream._add (core.js:959)
at CombineProducer._start (core.js:118)
at Stream._add (core.js:959)
at MapOperator._start (core.js:681)
at Stream._add (core.js:959)
at StartWithOperator._start (core.js:786)
正在試圖理解爲什麼,但沒有運氣遠。
文件* index.js *中的第6行是什麼? – bloodyKnuckles
'combine'部分在這裏工作正常:http://www.webpackbin.com/VkmIaiCtZ – bloodyKnuckles
謝謝你看看,它看起來像組合流到vtree時發生的問題。 webpackbin是一個很好的建議,這裏是附加代碼: [http://www.webpackbin.com/VkpnY30K-](http://www.webpackbin.com/VkpnY30K-) – ismapro
