通过白色空间或多个白色空间分裂

Right now I split words by one whitespace and store in an array: var keywds = $("#searchquery").text().split(" ");

现在我用一个空格分隔单词并存储在一个数组中:var keywds = $(“#searchquery”)。text()。split(“”);

The problem is there can/might be multiple white spaces. For example :

问题是可能/可能有多个空格。例如 :

"hello      world"

How would I still have the array = [hello, world]

我怎么还有数组= [你好,世界]

Use a regular expression (\s matches spaces, tabs, new lines, etc.)

使用正则表达式(\ s匹配空格,制表符,新行等)

$("#searchquery").text().split(/\s+/);

or if you want to split on spaces only:

或者如果您只想分隔空格:

 $("#searchquery").text().split(/ +/);

+ means match one or more of the preceding symbol.

+表示匹配前一个符号中的一个或多个。
