通过主题标签拆分字符串并使用 jQuery 保存到数组中? [英] Split string by hashtag and save into array with jQuery?

问题描述

我有一个包含一系列单词的字符串的 var，其中一些带有主题标签，例如:

I have a var that has a string with a series of words, some of which have hashtags, eg:

var words = "#hashtagged no hashtag #antoherhashtag";

我想将每个标签词保存到一个数组中，有点像:

I want to save each hashtagged word into an array, kind of like:

var tagslistarr = words.split(' ');

但我不确定如何让 # 和空格包围的字符.

But I am unsure of how to get the characters surrounded by both the # and the space.

有什么特殊的方法可以做到这一点吗?是否有一些 ASCII 字符我打算用来识别这个?

Is there a special way of doing this? Is there some ASCII characters I am meant to use to identify this?

推荐答案

DEMO

var words = "#hashtagged no hashtag #antoherhashtag";
var tagslistarr = words.split(' ');
var arr=[];
$.each(tagslistarr,function(i,val){
    if(tagslistarr[i].indexOf('#') == 0){
      arr.push(tagslistarr[i]);  
    }
});
console.log(arr);

tagslistarr = words.split(' ') 将带有空格的单词拆分为一个新数组

tagslistarr = words.split(' ') splits words with spaces to from a new array

$.each() 循环遍历 tagslistarr 数组的每个值

$.each() loops through the each value of tagslistarr array

if(tagslistarr[i].indexOf('#') == 0) 检查 # 是否在开头，如果这个条件是 true 将它添加到 arr 数组

if(tagslistarr[i].indexOf('#') == 0) checks is the # is in the beginning of the and if this condition is true it adds it into the arr array
