Javascript正则表达式可在'＆'，'-'或'>'上拆分

Question

I have a string like this:

var category = 'New & improved > crazy - whatever'

I'd like to convert it to:

var arr = ['New', 'improved', 'crazy', 'whatever']

Should work with any combination of ' & ', ' - ' or ' > ' (spaces included).

So far I'm doing:

var arr = [];
    if(obj.categories[i].name.indexOf(" > ") >= 0){
        var arr2 = obj.categories[i].name.split(" > ");
        for(var i = 0; i<arr.length; i++){
            if (arr[i].indexOf(' & ') >=0){
                var newarr = arr[i].split(' & ');
                arr.push(newarr);
            }else{
                arr.push(arr[i]);
            }
        }
    }

    if(obj.categories[i].name.indexOf(" - ") >= 0){
        var arr2 = obj.categories[i].name.split(" - ");
        for(var i = 0; i<arr.length; i++){
            if (arr[i].indexOf(' & ') >=0){
                var newarr = arr[i].split(' & ');
                arr.push(newarr);
            }else{
                arr.push(arr[i]);
            }
        }
    }else if(obj.categories[i].name.indexOf(" & ") >= 0){
        var arr = obj.categories[i].name.split(" & ");
        return arr;
    }else{
        return [obj.categories[i].name];
    }

but this doesn't work if there are both ampersands and dashes in the string. I feel like a regex could handle this much better anyhow, what's the best way to achieve this and make it relatively-futureproof for different use-cases (only involving the above separators, of course)?

Answer 1

var category = 'New & improved > crazy - whatever';
category.split(/\s*[-&>]\s*/); // => ["New", "improved", "crazy", "whatever"]

NOTE: - should not be in the middle. Otherwise it is interpreted as character range.

Answer 2

Try:
'New & improved > crazy - whatever'.split(/[>&-]/);

or without spaces in the result (but result may depend on the formatting of the initial string):
'New & improved > crazy - whatever'.split(/\\s+[>&-]\\s+/);

Answer 3

You can use this:

var result = yourstring.split(/[\s>&-]+/);

print(result);

Answer 4

var category = 'New & improved > crazy - whatever'
var arr = category.split(/[\&\>\-]/);
