[英]For in loop looping through array but not JS function
我正在使用Plotly.js渲染一些库存数据。 我希望总共有5张图表而不重复自己。 因此,我做了一个数组,给出了要调用的每个链接的键和值对。
var links = {
'microsoft':'https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=MSFT&apikey=APIKEY&datatype=csv',
'apple': 'https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=MSFT&apikey=APIKEY&datatype=csv',
'tesla':'https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=MSFT&apikey=APIKEY&datatype=csv',
'amazon':'https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=MSFT&apikey=APIKEY&datatype=csv',
'facebook':'https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=MSFT&apikey=APIKEY&datatype=csv'
};
从那里,我使用for in循环在每个键值对之间循环,并在两者之间使用我的plotly函数。
for (var key in links) {
//url of the data I am passing
Plotly.d3.csv(links[key], function(err, rows){
function unpack(rows, key) {
return rows.map(function(row) {
return row[key];
});
}
var trace = {
x: unpack(rows, 'timestamp'),
close: unpack(rows, 'open'),
high: unpack(rows, 'high'),
low: unpack(rows, 'low'),
open: unpack(rows, 'close'),
// cutomise colors
increasing: {line: {color: 'black'}},
decreasing: {line: {color: 'red'}},
type: 'candlestick',
xaxis: 'x',
yaxis: 'y'
};
var data = [trace];
var layout = {
dragmode: 'zoom',
showlegend: false,
xaxis: {
rangeslider: {
visible: false
}
}
};
//this key is the value of the id of the html element
Plotly.plot(key, data, layout);
});;
}
该函数运行良好,但仅打印DOM中的第一对。 我要所有人5.我不确定我在做什么错。
更新:
这是我尝试将这些项目渲染到的html元素。
<div class="container-fluid" id="home__page">
<div class="row ">
<div class="col-6">
<div id="microsoft">
</div>
</div>
</div>
<div class="row ">
<div class="col">
<div id="apple">
</div>
</div>
</div>
<div class="row ">
<div class="col">
<div id="tesla">
</div>
</div>
</div>
<div class="row ">
<div class="col">
<div id="amazon">
</div>
</div>
</div>
<div class="row ">
<div class="col">
<div id="facebook">
</div>
</div>
</div>
</div>
我以前从未使用过,我怀疑有两件事,要么给出并覆盖了一个固定的id /容器,要么不断地重新确定密钥。 您可以尝试一下吗,否则我将删除答案:
for (var key in links) {
(function(key,links){
//url of the data I am passing
Plotly.d3.csv(links[key], function(err, rows){
function unpack(rows, key) {
return rows.map(function(row) {
return row[key];
});
}
var trace = {
x: unpack(rows, 'timestamp'),
close: unpack(rows, 'open'),
high: unpack(rows, 'high'),
low: unpack(rows, 'low'),
open: unpack(rows, 'close'),
// cutomise colors
increasing: {line: {color: 'black'}},
decreasing: {line: {color: 'red'}},
type: 'candlestick',
xaxis: 'x',
yaxis: 'y'
};
var data = [trace];
var layout = {
dragmode: 'zoom',
showlegend: false,
xaxis: {
rangeslider: {
visible: false
}
}
};
//this key is the value of the id of the html element
Plotly.plot(key, data, layout);
});;
})(key,links)
}
