更改AngularJS ngTrim行为

问题描述

我正在使用AngularJS 1.5.6版.我有一个大型应用程序，其中包含许多文本区域和文本输入.我今天发现了一个错误，该错误是由AngularJS为文本类型输入修剪输入的默认行为引起的.我想将此行为从默认情况下的修剪更改为默认情况下不修剪.

I am using AngularJS version 1.5.6. I have a large application with lots of text areas and text inputs. I discovered a bug today caused by the default AngularJS behavior of trimming input for text type inputs. I would like to change this behavior from trimming by default to not trimming by default.

有没有一种简单的方法来执行此操作，而不是在我的应用程序中遍历数百个文本区域和文本输入.(也许是全局的还是编写我自己的指令?)

Is there an easy way to do this rather than to go through hundreds of textareas and text inputs in my application. (perhaps globally or writing my own directive?)

这是文档页面，描述ng-trim(ngTrim)的默认行为.

Here is the documentation page describing the default behavior of ng-trim (ngTrim).

推荐答案

以下指令应适用于所有输入type = text字段.默认情况下，它将为每个输入字段将ngTrim的值设置为false.如果需要，可以为文本区域创建一个类似的页面.

The below directive should work for all the input type=text fields. It will set the value of ngTrim false by default for every input field. And a similar one can be created for the textarea if required.

.directive('input', function($compile){
   return {
   link(scope, element, attrs) {
    if (element.attr('type') === 'text') {
      attrs.$set('ngTrim', 'false');
    }
  }
  };
 });
