Question

我有一个动态字符串，我想从String中删除特定的格式文本。（即*号码）

例如：//Define screen sizes let screenSize: CGRect = UIScreen.mainScreen().bounds let screenWidth = screenSize.width let screenHeight = screenSize.height // Sizes of centre cards let centreCardWidth = screenWidth/5 let centreCardHeight = (screenWidth/5) / 0.625 let centralizeViewHorizontalCard = (screenWidth/2) - ((screenWidth/5) / 2) let centralizeViewVerticleCard = screenHeight / 2 UIView.animateWithDuration(0.25, delay: 0.5, options: [], animations: { centreCard3.frame = CGRectMake(centralizeViewHorizontalCard, centralizeViewVerticleCard, centreCard3.frame.size.width, centreCard3.frame.size.height) }, completion: nil)

输出：/1*Region 1/42*Europe/51*Test/100*New Folder/119*New Folder

提前致谢。

Answer 1

＆＃13;

var str = "/1*Region 1/42*Europe/51*Test/100*New Folder/119*New Folder";

var regex = /(\/\d+\*)/g;

var output = str.replace( regex, '/' );

console.log( output );

＆＃13;

Answer 2

另一种解决方案是搜索一个数字（\d+），然后搜索*（\*）并将其替换为空。

var dynamic="/1*Region 1/42*Europe/51*Test/100*New Folder/119*New Folder";

var edited=dynamic.replace(/\d+\*/g, '');

console.log(edited);

Answer 3

以下是使用split和join的另一种方式：

var str = '/1*Region 1/42*Europe/51*Test/100*New Folder/119*New Folder',
    result = str.split(/\d+\*/).join('');   

console.log(result);
