Angular II slash avoiding Pipe

I am working on developing a customized pipe in Angular 2 that will handle the replacement of the backslash ('\') character in a given string. This backslash is commonly used to escape special characters.

What I have accomplished so far:

The pipe class looks like this:

@Pipe({
  name: 'escapeSlashPipe'
})

export class EscapeSlashPipe implements PipeTransform {
  transform (value: string): any{
    value = value.replace(/\\"/g, '"');
    return value;
  }
}

Here is how it is implemented in HTML:

<p>{{message | escapeSlashPipe}}</h4>

For example, if the input string is:

"ghda\'nja asda\\dasda dasj\' \"das\'da\\d as\\as\\sad"

After applying the pipe, the output should be:

"ghda'nja asda\dasda dasj' das'da\d as\as\sad"

The main objective of this pipe is to selectively replace only those backslashes that are used for escaping characters.

Answer №1

When the code value.replace(/\\"/g, '"'); is used, it targets the sequence of characters: \\" and replaces them with just a double quote character ".

It's important to note that this method specifically works for double quotes.

If you want to try something different:

let value = "Lorem \\\" ipsum \\' dolorem \\\\ javascript";
// value: Lorem \" ipsum \' dolorem \\ javascript

// JavaScript has its own way of escaping characters, so additional backslashes were needed in this case

value = value.replace(/(\\)(\W)/g, '$2');
// value: Lorem " ipsum ' dolorem \ javascript

Answer №2

"hjdf\'a asdd\\sdasda dasj\'d as\xda\sa'sdas."replaceAll(/\"/g,"'")

Give the above code a shot and share your results with me. This is what I got when I tried it:

"hjdf'a asdd\dasda dasj'd as\xda\sa'sdas"
