如何从 jquery 的序列化字符串中删除空格？

Question

var queryString = $('#formname').serialize();
$.post(queryString, function(data) { ...

Request URL sometimes becomes

http:\\domain.com\\page.php?parm=1&contr y=2&...

how to remove the space in the text of country? I had tried

 queryString.replace(/\s/g, '')

and

.trim 

but no success..

Thanks,

Answer 1

replace works fine. Just strings are immutable , so you have to store or use directly the result of replace because it won't update your variable .

Quick note: this is kind of weird to have backslashes unescaped in your URL, but... eh, that's yours.

 const url = 'http:\\domain.com\\page.php?parm=1&contr y=2&...'; console.log(url.replace(/\\s/g, '')); console.log(url);

By the way, trim only removes outer spaces.

 const str = ' Hello World! '; console.log(str); console.log(str.trim());

Answer 2

我相信使用trim()可以，trim()去掉不必要的空格

yourstring.trim()
