在 JavaScript 中将逗号分隔的字符串转换为数组

Question

如何将此字符串转换为lenght=4且所有项目都是字符串的数组？

var str= "[bc, cccc, 14.35],[B, 222],[222, p11, 11s],[cccc, 14.35, D, 11s]";

Answer 1

Use JavaScript split("spacer") to perform this task :

JAVASCRIPT

var str = "[bc, cccc, 14.35],[B, 222],[222, p11, 11s],[cccc, 14.35, D, 11s]";
var str_array = str.split("],");
console.log(str_array.lenght); // display "4"

I used ], as spacer because you would have some others elements to be splitted as they contain several commas.

SPECIFIC ADVICE If you need to remove ] and [ remaining characters, you can use replace("to_be_replaced", "replacer") as followed :

str_array.forEach(function(entry) {
    entry.replace("]", "");
    entry.replace("[", "");
});

Answer 2

var str= "[bc, cccc, 14.35],[B, 222],[222, p11, 11s],[cccc, 14.35, D, 11s]".split("],[");

Answer 3

Following will preserve ] if you want that:

var str= "[bc, cccc, 14.35],[B, 222],[222, p11, 11s],[cccc, 14.35, D, 11s]";
var res = str.split('],').join(']],').split('],')

Result:

res = ["[bc, cccc, 14.35]","[B, 222]","[222, p11, 11s]","[cccc, 14.35, D, 11s]"]

 var str = "[bc, cccc, 14.35],[B, 222],[222, p11, 11s],[cccc, 14.35, D, 11s]"; var res = str.split('],').join(']],').split('],') for (var k in res) { document.body.innerHTML += res[k] + "<br/>" }

Answer 4

You can remove the first and the last brackets and use split function.
Here is the working code snippet which converts your string to 4 strings without any brackets or outer commas.

 var s = "[bc, cccc, 14.35],[B, 222],[222, p11, 11s],[cccc, 14.35, D, 11s]"; var sArr = s.substr(1, s.length - 2).split('],['); for (var k in sArr) document.body.innerHTML += sArr[k] + "<br/><br/>";
