我这样说:

A sampletext
b sampletext3
c exampletext    
A sampletext587
b sampletext5
b sampletextasdf
d sampletext4
b sometext
c sampletextrandom

在联合材料中,我如何把从<条码>b开始的行文改为上例?

感谢!

最佳回答

With

"b sampletext3".replace(/^b/gm,function(x){return x.toUpperCase()})
B sampletext3

并赋予它以寻求反对

String.prototype.toTitleCaseB=function(){
    return this.replace(/^b/gm,function(x){return x.toUpperCase()})
}

稍后将使用

"b sampletext3".toTitleCaseB()
B sampletext3
问题回答
  1. split the string on
  2. loop over the resulting array
  3. use substring to extract the first letter and test it
  4. optionally set the array item to itself.toUpperCase()
  5. join the array
