So, I have the following code, and it's not working, and I'm not sure why. Any suggestions?
HTML:
<input type="number" placeholder="#" id="lineSpace"/>
<br/><br/><button id="go">update text!</button>
JavaScript (jQuery)
$(document).ready(function() {
var lineSpace = $("#lineSpace").val();
$("#go").click(function(){
alert("LINE SPACE: "+lineSpace+"");
});
This was a test to see if my variable was being gathered, but it seems not. The alert appears but simply says "LINE SPACE: ", without placing the variable after it. When I define the like this var lineSpace = "random number";
(which is no use to me, as I need a value that is entered from the user-side), however, it works fine.

Because you are assigning lineSpace when the page loads, and it's obviously blank then.
Move var lineSpace = $("#lineSpace").val();
into your click handler (above the alert()
function call).
