How to put a string from an input field and put it into a function [duplicate]

jQuery:

Message.send($("input.draft").val());

javascript:

Message.send(document.querySelector("input.draft").value);

No jQuery needed. I'm not sure what you mean by place it into the Message.send() function (in string form), so I assume you get the value in the text input and use it as an argument in the Message.send() function.

Try this:

Message.send(document.getElementsByClassName("draft")[0].value);

Assuming your input field is something like this:

<input type="text" id="someInputField" name="someInputField" class="inputFields" />

You could do this

<script type="text/javascript">
   //We use the field's id to refer to it and get to its value (the text in it):
   var message = $('#someInputField').val();
   //And then you might call the function like:
   nameOfTheFuntion(message);
</script>

You would need to have jQuery libraries to make it work though, but you could do without them by replacing:

$('#someInputField').val();

with

document.getElementById('someInputField').val();

Give your <input> box an id for example

<input type="text" id="blah" />

In your javascript you are able to reference the <input> like so:

var strBlah = document.getElementById("blah").value;

Now you have the value typed into the <input> box so you would do the following:

Message.send(strBlah)
