Question

我将一些案文与 Java文混为一谈。我要说几句:

"hello wold <1> this is some random text <3> foo <12>"

我需要将以下次体放在一个阵列中:

myArray[0] = "hello world ";
myArray[1] = "<1>";
myArray[2] = " this is some random text ";
myArray[3] = "<3>";
myArray[4] = " foo ";
myArray[5] = "<12>";

www.un.org/Depts/DGACM/index_spanish.htm 请注意,每当我碰到一个“带”;“编号”和“序列时,我就将座标分开。

我尝试将座标与一个固定的插图(/<d{1,3}>分开,但当我这样做时,我会放松“带”;“编号”和顺序。换言之,我最后说的是“弱小的世界”,“这是一些随机案文,即“oo”。请注意,我放松了“和”;1>”、“<3>”和“<12>”等字样。我如何能够解决这一问题?

你们需要抓住顺序保留。

var str = "hello wold <1> this is some random text <3> foo <12>"

str.split(/(<d{1,3}>)/);

// ["hello wold ", "<1>", " this is some random text ", "<3>", " foo ", "<12>", ""]

在一些浏览器中,如果捕获组有问题,你可以手工操作,如:

var str = "hello wold <1> this is some random text <3> foo <12>",    
    re = /<d{1,3}>/g,
    result = [],
    match,
    last_idx = 0;

while( match = re.exec( str ) ) {
   result.push( str.slice( last_idx, re.lastIndex - match[0].length ), match[0] );

   last_idx = re.lastIndex;
}
result.push( str.slice( last_idx ) );
