正则表达式分割字符串但捕获sperator

I have string say "dd month yyyy" and I want split to convert to array like ["dd", " ", "month", " ", "yyyy"].

我有字符串说“dd month yyyy”，我希望拆分转换为数组，如[“dd”，“”，“month”，“”，“yyyy”]。

What I have so far and this method works. But I'm looking for Reg expression to do if someone can help?

我到目前为止，这种方法有效。但是，如果有人可以提供帮助，我正在寻找Reg表达吗？

function toArray(format) {
 var vDateStr = '';
var vComponantStr = '';
var vCurrChar = '';
var vSeparators = new RegExp('[\/\\ -.,\'":]');
var vDateFormatArray = new Array();

for (var i=0; i < pFormatStr.length; i++ )
{
    vCurrChar = pFormatStr.charAt(i);
    if ( (vCurrChar.match(vSeparators) ) || (i + 1 == pFormatStr.length) ) // separator or end of string
    {
        if ( (i + 1 == pFormatStr.length) && ( !(vCurrChar.match(vSeparators) ) ) ) // at end of string add any non-separator chars to the current component
        {
            vComponantStr += vCurrChar;
        }
        vDateFormatArray.push( vComponantStr );
        if ( vCurrChar.match(vSeparators) ) vDateFormatArray.push( vCurrChar );
        vComponantStr = '';
    }
    else
    {
        vComponantStr += vCurrChar;
    }

}
return vDateFormatArray;
}

3 个解决方案

#1

Simple:

简单：

> "10 Jan 2015".split(/\b/g)
< ["10", " ", "Jan", " ", "2015"]

This will split on a word boundary.

这将分裂为单词边界。

#2

I assume that "mm dd yyyy" will actually be numbers, but this will work for the strings as well.

我认为“mm dd yyyy”实际上是数字，但这也适用于字符串。

var date ="01 02 1292";

var dateArr = date.match(/[^\s]+|\s/g);

document.write(JSON.stringify(dateArr));

#3

function toArray(format) {
  var r = new RegExp('([0-9]{2})( )([0-9]{2})( )([0-9]{4})');
  return format.match(r).slice(1);
}

document.write(JSON.stringify(toArray("30 12 1980")));
