Replace line breaks without using the \r\n characters

Currently working on a new website and exploring some JavaScript functionalities. Being a beginner in this field, I apologize if my question seems basic :)

I have a JSON string with line breaks that are causing issues when trying to parse it into a JSON object. I attempted to remove the line breaks using:

stringJSON.replace(/(\r\n|\r|\n)+/, '');

However, despite applying this code, the line breaks still persist when I alert the string.

Any suggestions or alternatives?

Thank you in advance,

Wiwi :)

JSON:

[
    {
        "key0": "value 0",
        "key1": "value 1",
        "key2": "value 2"
    },
    {
        "key0": "value 0",
        "key1": "value 1",
        "key2": "value 2"
    }
]

Answer №1

Make sure to assign the result of the replace operation back to the stringJSON variable if your intention is to update its value.

stringJSON = stringJSON.replace(/(\r\n|\r|\n)+/g, '');

Remember that in JavaScript, strings are immutable, so the original string remains unchanged after a replace operation.

Keep in mind that using the global flag (g) in the regex allows for replacing multiple occurrences. Without it, only the first instance would be replaced.
