You don't need jquery for this...
你不需要jquery...
var str = " Hello World! ";
var trimmedStr = str.trim();
console.log(trimmedStr);
This will output the following in the console:
这将在控制台中输出以下内容：
"Hello World!"
“你好，世界！”

You don't need to convert anything. From the Node.js console:
你不需要转换任何东西。从 Node.js 控制台：
' hello '.trim()
works fine. It reduces to:
工作正常。它简化为：
'hello'
as expected. You need only invoke the function on the string literal or a string variable.
正如预期的那样。您只需要在字符串文字或字符串变量上调用该函数。

Try this work for me
为我尝试这项工作
var str = " Hello World! ";
var trim_leftright = str.replace(/^\s*|\s*$/g, ''); // left and right trim
console.log(trimleftright);
var trim_left = str.replace(/^\s*/, ''); // left trim
console.log(trim_left);
var trim_right = str.replace(/\s*$/, ''); // right trim
console.log(trim_right);
