正则表达式模式[＃[＃hello]＃]在javascript中匹配

Question

var str1 = "hello <span contenteditable="false" class="underlineText hashtags hello">hello<span style="display:none;"> [#[#hello]#] [#[#hi]#]  [#[#welcome]#]</span></span>"

var arr = textToPost.match(/#^[a-zA-Z0-9]/g)

我想提取符合此模式的字符串[＃[＃*]＃]。

试试这个正则表达式，它适用于我

= delete;

var reg = /\[[#[a-zA-Z0-9]+]#]/ig;
