Javascript – return responseText from jQuery.get()

ajaxgetjavascriptjquery

I tried to do something like this :

var msg = $.get("my_script.php");

I thought msg would be set to the text returned by my_script.php,i.e. the responseText of the jqXHR object.
It apparently doesn't work like that as msg is always set to "[object XMLHttpRequest]"

Is there a quick 1 line way to do what I want?

Thanks.

After some testing, I ended up finding a solution.

I need the call to be synchronous, $.get shorthand function is always asynchonous, so I will need to use $.ajax, like this:

var msg = $.ajax({type: "GET", url: "my_script.php", async: false}).responseText;

I don't think there is a better way to do this, thanks for your answers.

Javascript – jQuery get textarea text

Why would you want to convert key strokes to text? Add a button that sends the text inside the textarea to the server when clicked. You can get the text using the value attribute as the poster before has pointed out, or using jQuery's API:

$('input#mybutton').click(function() {
    var text = $('textarea#mytextarea').val();
    //send to server and process response
});

Javascript – Remove properties from objects (JavaScript)

To remove a property from an object (mutating the object), you can do it like this:

delete myObject.regex;
// or,
delete myObject['regex'];
// or,
var prop = "regex";
delete myObject[prop];

Demo

var myObject = {
    "ircEvent": "PRIVMSG",
    "method": "newURI",
    "regex": "^http://.*"
};
delete myObject.regex;

console.log(myObject);

For anyone interested in reading more about it, Stack Overflow user kangax has written an incredibly in-depth blog post about the delete statement on their blog, Understanding delete. It is highly recommended.

If you'd like a new object with all the keys of the original except some, you could use the destructuring.

Demo

let myObject = {
  "ircEvent": "PRIVMSG",
  "method": "newURI",
  "regex": "^http://.*"
};

const {regex, ...newObj} = myObject;

console.log(newObj);   // has no 'regex' key
console.log(myObject); // remains unchanged
