如何将json转换为纯文本？

Question

How to convert JSON to plain text?

{"Days":["is not a number"]} to Days is not a number.

Here is the code:

$('.best_in_place').bind("ajax:error", function(jqXHR,error, errorThrown) {
  alert(error.responseText);
});

Answer 1

As you're using jQuery, this might help:

var result = '';
$.each(error.responseText, function(key, value) {
    result += key + ' ' + value;
});

This will also work and can easily be adjusted if the response holds multiple key-value-pairs.

Answer 2

Convert the response into JSON object and parse its key-value pair

var error = JSON.parse( error.responseText );
for( var name in error ) {
    console.log( name + " " + error[ name ] ); // Days is not a number
}

Answer 3

Convert any json to plain text.

Installation

npm install json-to-plain-text

var convert = require('json-to-plain-text');

var jsonData = {
    "place_id": "173937105",
    "osm_type": "way",
    "osm_id": "319992693",
    "lat": "17.861533866867224",
    "lon": "78.8081441896764",
    "display_name": "Satadar Nagar, Ward 116 Allapur, Hyderabad, Kukatpally mandal, Telangana, 500018, India",
    "address": {
        "neighbourhood": "Satadar Nagar",
        "suburb": "Ward 116 Allapur",
        "city": "Hyderabad",
        "county": "Kukatpally mandal",
        "state": "Telangana",
        "postcode": "500018",
