如何删除文本中的空格 [英] How to remove whitespace in text

问题描述

如何在Angular应用程序中修剪文本字符串?

How can I trim a text string in my Angular application?

示例

{{ someobject.name }}  

someobject.name结果为名称abc"

someobject.name results in "name abc"

我想要实现的是将名称命名为"nameabc" (删除所有空格).

What I like to achieve is name to be "nameabc" (remove all whitespaces).

我已经创建了一个管道，并将其包含在打字稿文件和模块中

I already created a pipe and included this in the typescript file and module)

PIPE:

import { Pipe, PipeTransform } from "@angular/core";

@Pipe({ name: 'trim' })
export class TrimPipe implements PipeTransform {
    transform(value: any) {
        if (!value) {
            return '';
        }

        return value.trim();
    }
}

{{someobject.name |修剪}}仍以"name abc"代替"nameabc"}}

{{ someobject.name | trim }} still results in "name abc" instead of "nameabc" }}

推荐答案

根据文档，trim()方法会删除 trailing 和 leading 空格，而不是中间.

According to the docs, the trim() method removes trailing and leading whitespaces, not those in the middle.

如果要删除所有空格，请使用replace函数:

If you want to remove all whitespaces use the replace function:

"name abc".replace(/\s/g, "");
