  javascript jquery html5 canvas
  I have a very nice pie/donut chart drawn with chartjs.org. Works great. Easy to implement. Animates nicely. I also have a label that needs to update when the user hovers over the chart. Mousemove fires and returns the rgba coordinately as expected in FF and IE10/9. But not Webkit. It seems to get all mixed up… Unexpected behavior coming from Chrome/Safari. Any idea how to fix this?This is the where the problem exist:var canvasOffset = $(this).offset(); var canvasX = Math.floor(e.pageX – canvas

  javascript jquery
  I’ve been struggling with this issue for a while now. Maybe you can help.I have a table with a checkbox at the beginning of each row. I defined a function which reloads the table at regular intervals. It uses jQuery’s load() function on a JSP which generates the new table.The problem is that I need to preserve the checkbox values until the user makes up his mind on which items to select. Currently, their values are lost between updates.The current code I use that tries to fix it is:refreshId = s

  html web jade dust.js
  I’ve been looking all over for something that will let me precompile static websites using Grunt. It needs to have partials, so I can include things like a common header/footer across the pages.So far, I’ve only really found Jade, which has a grunt plugin, and this plugin for Grunt that compiles Dust.js templates to static HTML. I don’t really like Jade’s syntax, and the Dust plugin for Grunt is less than ideal. Any suggestions for a good static HTML templating language with Grunt support?

  dust.js
  I’ve just started using dust.js. And I’ve come across a problem. I need to specify a condition (json parameters existence) in template. Depending on it some inner html should be rendered or not. So according to the description I should use smth like this:{?param_name} … {:else} {/param_name}But I need to check a complex condition, so I go for logic helper – {@if..}. And it turns out that I’d like to use path in condition. So.. The result looks:{@if cond=”{myObject.property1} || {myObject.prope

  I’m using the full, Linked In version 1.2.0 of dust.js and am trying to define a filter for use when rendering a JSON view with a dust template. When I include this line in the page script:_.extend(dust.filters, {foo: function(value){ return ‘foo’; }});it results in this error in Chrome’s debugger:Uncaught ReferenceError: _ is not defined If I add the filter definition to where the other filters are in the dust .js file, it works. What am I doing wrong?

  javascript dust.js
  I’m trying to render HTML using compiled templates with dust.js in a browser (not server-side with node.js). If I compile the template in the client-side javascript, it works fine. If I pre-compile the template and include it as a script tag as recommended, the dust.loadSource statement results in the Chrome debugger saying: “Uncaught ReferenceError: nowork is not defined”, where “nowork” is the template name. So…This HTML and script works:<!DOCTYPE html> <html lang=”en”> <head&
