When I click on a canvas and drag my mouse, the cursor changes to a text-selection cursor. How can I prevent this?
You can bind a mousedown event in your canvas to prevent default behavior.
Something like:
// with jQuery$( "#canvasId" ).mousedown(function(event){ event.preventDefault();});// without jQuerydocument.getElementById( "canvasId" ).onmousedown = function(event){ event.preventDefault();};Here is the updated fiddle: http://jsfiddle.net/MZ9Xm/1/
You will need to test this to see if there is some side effect in what you are doing.
Have you tried using the CSS cursor property ?
canvas { cursor: pointer;}It should display the default cursor.
Try this:
var canvasEls = document.getElementsByTagName('canvas'), preventHl = function () { return false; }, i = 0;while (i < canvasEls.length) { canvasEls[i].onmousedown = preventHl; i += 1;}Returning false will prevent default actions such as highlighting from occurring.
