First ever post to Stackoverflow and coding newb. I have seen many a example in which people have successfully set CSS attributes using jQuery. However, after many frustrating hours, I have still yet to see what obvious thing is wrong. Here's my very simplified code. I know that if I add this attribute manually to the CSS, it has the desired effect. However, I cannot get it to work using jQuery. Any help or suggestions would be much appreciated. I feel as if this should be so obvious but I don't see it.
I am using RoR (and I have included //=require jquery in app.js)
CSS
#magicaldiv{
margin-left: -175px;
margin-top: -20px;
width:350px;
height:40px;
position:absolute;}
JS
var buttonPointer = $('#magicaldiv');
$(document).ready(updatePointer);
$(window).resize(updatePointer);
function updatePointer(){
buttonPointer.css('left', 200);}
I have also tried several iterations of jQuery and JS including but not limited to..
JS
document.getElementById("magicaldiv").style.left = 200;
and
var left = 200 + "px";
buttonPointer.css('left', left);
and
buttonPointer.css('left', '200px');
even though the documentation suggests that all numbers will be turned into a string and assumed to be px.
You may need to wrap the buttonPointer
definition in a document.ready
call, depending on the order of your source code.
var buttonPointer;
function updatePointer(){
buttonPointer.css('left', 200);}
$(document).ready(function() {
buttonPointer = $('#magicaldiv');
updatePointer();
});
$(window).resize(updatePointer);
