什么是vbscript Chr（）函数的JavaScript等价物？

Question

I need to convert following lines to JavaScript:

cOrderNumList = frmSearch.OrderNumList.Value
cOrderNumList = Replace(cOrderNumList, Chr(10), "")
aOrderNumList = Split(cOrderNumList,",")

What is the JavaScript equivalent of Chr(10)

Answer 1

cOrderNumList = frmSearch.OrderNumList.Value;
cOrderNumList = cOrderNumList.replace(String.fromCharCode(10), "");
aOrderNumList = cOrderNumList.split(",");

Are my changes correct?

Answer 2

你需要String.fromCharCode() ：

cOrderNumList = Replace(cOrderNumList, String.fromCharCode(10), "")

Answer 3

To convert a char code to a string you can do this:

var outputString = yourString.replace(cOrderNumList, String.fromCharCode(10))

As you will notice, this converts the char code to a one-letter string. You can't truly convert to a pure char because the char type doesn't exist in JavaScript.

Answer 4

You can use String.fromCharCode but if your character is hardcoded, the best is to simply use "\\n" .

And as replace would only replace the first one, I suggest this simple regular expression :

cOrderNumList = cOrderNumList.replace(/\n/g, "")
