convert string array to integer array
提问by Jonas Anseeuw
I have created an array:
我创建了一个数组：
var endFlowArray = new Array;
for (var endIndex in flowEnd) { // <- this is just some numbers
for (var i in dateflow) { // <- same thing

if (check >= 0) {
endFlowArray.push(i);
flowEnd[endIndex] = null;
}
}
}

Strings in the console are symbolized by wrapping them in quotes. By that fact, we can assume that iis a string. Convert it to an integer and it will no longer be a string and no longer have those quotes.
控制台中的字符串通过用引号括起来来表示。根据这个事实，我们可以假设这i是一个字符串。将其转换为整数，它将不再是字符串，也不再有那些引号。
endFlowArray.push(+i);
Your "numbers" in flowEndand dateFloware actually strings, not numbers.
您的“数字”中flowEnd和dateFlow实际上是字符串，而不是数字。

要转换整个数组的数据类型，我们可以使用map()：
let numberArray = stringArray.map(Number)

try this:
尝试这个：
let numberArray = stringArray.map(el=>parseInt(el))
