How to realize full-width and half-width conversion by JavaScript
This article mainly introduces JavaScript how to achieve full-width half-width conversion, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.
Full-width half-width conversion / / iCase: 0 full-to-half, 1-and-a-half to full, other no conversion
Function chgCase (sStr, iCase) {
If (
Typeof sStr! = "string" | |
SStr.length full * /
For (I = 0; I)
< sStr.length; i += 1) { iCode = sStr.charCodeAt(i); if (iCode == 32) { iCode = 12288; } else if (iCode < 127) { iCode += 65248; } oRs.push(String.fromCharCode(iCode)); } } else { /*全->Half * /
For (I = 0; I)
< sStr.length; i += 1) { iCode = sStr.charCodeAt(i); if (iCode == 12288) { iCode = 32; } else if (iCode >65280 & & iCode < 65375) {
ICode-= 65248
}
ORs.push (String.fromCharCode (iCode))
}
}
Return oRs.join ("")
