jQuery: How to trim new line and tab characters between words

javascriptjquery

提问by Anil Kumar Pandey

Hi I am getting new line(\n) and tab(\t) characters between words and I was trying to trim those by using $.trim()function but its not working. So can anyone have some solution for this type of problem.

嗨,我在单词之间得到新行(\n)和制表符(\t)字符,我试图通过使用$.trim()函数来修剪它们,但它不起作用。因此,任何人都可以为此类问题提供一些解决方案。

Ex:

前任:

var str = "Welcome\n\tTo\n\nBeautiful\t\t\t\nWorld";
alert($.trim(str));

the above code is not working.

上面的代码不起作用。

str.replace(/\s+/g, " "); //try this

reference replace

参考替换

\smatches any newline or tab or white-space

\s匹配任何换行符或制表符或空格

You can do this:

你可以这样做:

var str = "Welcome\n\tTo\n\nBeautiful\t\t\t\nWorld";
alert($.trim(str.replace(/[\t\n]+/g,' ')));
// results is  "Welcome To Beautiful World"

回答by Paul Draper

That is expected. trimonly takes care of leading and trailing whitespace.

这是预期的。trim只处理前导和尾随空格。

Instead, use

相反,使用

str.split(/\s/).join(' ');

In your example, this returns

在您的示例中,这将返回

"Welcome To Beautiful World"

回答by Satpal

You can use replacewith a regular expression:

您可以使用替换正则表达式

var str = "Welcome\n\tTo\n\nBeautiful\t\t\t\nWorld";
alert($.trim(str.replace(/[\t\n]+/g, ' ')));
