  • Browser Issue: Charts are not rendered on IE8

    - by Rachel
    We have inhouse library which uses canvas for displaying charts in my application. And dojo as scripting language.Everything is fine, but my charts are not appearing in IE8. I google about this, and found that there is some VML issue in IE8. I found this: var printChart = function(time, freq){ if (!document.namespaces['g_vml_']) { document.namespaces.add('g_vml_', 'urn:schemas-microsoft-com:vml', '#default#VML'); } if (!document.namespaces['g_o_']) { document.namespaces.add('g_o_', 'urn:schemas-microsoft-com:office:office', '#default#VML'); } if (freq === undefined) { this.freq = "1mi"; } if (time === undefined) { this.time = "1dy"; } self.reload(); } Now I was trying to add this in my DOJO code and that is creating problem. As when I do document.namespace I get firebug error 'document.namespaces is undefined'. Q: How can we fix this, are the any better alternative approaches for the same, basic problem am having is browser related, charts are rendered properly on other browsers but not on IE8, any suggestions ? Update: What are ways to deal with such cross browser issue ?

  • Relative Dates with Datejs

    - by Prasanna
    I have a requirement where in, I have to parse the dates relative to a date object returned from the server side. But the datejs library always considers only the browsers date object. The situation is something like this: The server gives back the date in PST and the browser is in IST. And all the inputs are getting parsed with respect to the current date in IST instead of current date in PST. Is there any way I could resolve this. Or could you suggest any workarounds. Thanks in advance.

    - by Dave
    I have an array im trying to loop through to create a new type of array specific to my current page. My array looks like this: //$_SESSION['data'] = Array ( [0] => 1 [1] => 0 [2] => Tom [8] => 1 [4] => 1 [5] => Array ( [7] => Array ( [0] => Andrew [1] => 1 [2] => 1 [4] => 0 [5] => avatar.jpg [6] => 1 ) ) [6] => Array ( [0] => 1 [1] => 2 ) ) So in my JS file i have this: var stats = <? echo $_SESSION['data'][5]); ?> ; //this is the array my_data = new Array(); for(var key in stats){ if(key in my_data){} else { //prevent double entry my_data[key] = new Array(); my_data[key][0] = stats[key][6]; my_data[key][1] = stats[key][5]; my_data[key][2] = stats[key][2]; my_data[key][3] = stats[key][0]; } } console.log(my_data); Now in console.log i get this : [undefined × 7, Array[4] 0: "1" 1: "avatar.jpg" 2: "1" 3: "Andrew" length: 4 __proto__: Array[0] ] I'm wondering why it is saying undefined x7?

  • Click Function on jQuery plugin only allows for single click

    - by user1427307
    I've created this simple plugin to add multiple animations on click but the problem is that once the object is clicked it can not repeat the animation by clicking again, i can't figure out why the added class is not removing itself after the click function is complete to allow it to be clicked again and repeat.. any suggestions? (function($) { $.fn.vivify = function(options) { var defaults = { animation: 'bounce', }; var options = $.extend(defaults, options); return this.each(function() { var o = options; var obj = $(this); var animation = o.animation; obj.bind("click", function() { obj.addClass(o.animation); obj.addClass('vivify'); }, function() { obj.removeClass(o.animation); }); }) } })(jQuery);

  • jquery split() and indexOf results in "Object doesn't support this property or method"

    - by chris
    I have the following code: var selected = $('#hiddenField').val().split(","); ... if (selected.indexOf(id) > 0) { ... set value ... } I'm dynamically creating a CheckBoxList, and trying to remember the state of the checkboxes by putting the selected IDs into the hidden field. I get an error stating that "Object doesn't support this property or method". My assumption is that selected is an array, which should support indexOf. Is that incorrect?

  • jquery multiple select x rails edit action

    - by VP
    Hi, i'm using the JQUERY multiselectable plugin. Because it's get one select box and transform it in two, where you can move one selected option to another select box. The problem is that i'm facing some problems with the edit action. When i load the form, the selected values (that are saved in my model) are not being populated in the "selected" select box. There is anybody with a good idea about how to "automatically" move the selected values in my database from the "available to be selected" to "selected" options? For now i'm doing something like <%= select "product", :option_ids, options_for_select(Option.all.map { |opt| [opt.description, opt.id]}), {},{:multiple=> true,:class=>'multiselect'} %> Here i can see already the problem. I could just use as options_for_select just all options - the options that are already choosed in my model. The problem is how to update the select box with this information?

  • Prevent click event on the clicked element?

    - by nainy
    I have a click event on the body of my document: $("body").on('click.findElem', function(e) { e.stopPropagation(); e.preventDefault(); self.hinter(e.target); return false; }); It basically catches the clicked target and does something to it. However, there are some targets that already have a click event on them, and they prevent my click from being executed at all. How do I overcome that issue? I tried unbinding it, but the click doesn't even work at all to actually execute the unbinding.

  • Improve this snippet from a prototype class

    - by seengee
    This is a snippet from a prototype class i am putting together. The scoping workaround feels a little hacky to me, can it be improved or done differently? var myClass = Class.create({ initialize: function() { $('formid').getElements().each(function(el){ $(el).observe("blur", function(){ this.validateEl(el); }.bind(this,el)); },this); }, validateEl: function(el){ // validate $(el) in here... } }); Also, it seems to me that i could be doing something like this for the event observers: $('formid').getElements().invoke("observe","blur" ... Not sure how i would pass the element references in though?

  • How do I remove elements from a jQuery wrapped set

    - by Bungle
    I'm a little confused about which jQuery method and/or selectors to use when trying to select an element, and then remove certain descendant elements from the wrapped set. For example, given the following HTML: <div id="article"> <div id="inset"> <ul> <li>This is bullet point #1.</li> <li>This is bullet point #2.</li> <li>This is bullet point #3.</li> </ul> </div> <p>This is the first paragraph of the article</p> <p>This is the second paragraph of the article</p> <p>This is the third paragraph of the article</p> </div> I want to select the article: var $article = $('#article'); but then remove <div id="inset"></div> and its descendants from the wrapped set. I tried the following: var $article = $('#article').not('#inset'); but that didn't work, and in retrospect, I think I can see why. I also tried using remove() unsuccessfully. What would be the correct way to do this? Ultimately, I need to set this up in such a way that I can define a configuration array, such as: var selectors = [ { select: '#article', exclude: ['#inset'] } ]; where select defines a single element that contains text content, and exclude is an optional array that defines one or more selectors to disregard text content from. Given the final wrapped set with the excluded elements removed, I would like to be able to call jQuery's text() method to end up with the following text: This is the first paragraph of the article.This is the second paragraph of the article.This is the third paragraph of the article. The configuration array doesn't need to work exactly like that, but it should provide roughly equivalent configuration potential. Thanks for any help you can provide!

  • Backbone View: Inherit and extend events from parent

    - by brent
    Backbone's documentation states: The events property may also be defined as a function that returns an events hash, to make it easier to programmatically define your events, as well as inherit them from parent views. How do you inherit a parent's view events and extend them? Parent View var ParentView = Backbone.View.extend({ events: { 'click': 'onclick' } }); Child View var ChildView = ParentView.extend({ events: function(){ ???? } });

  • How do you have grayed out text in a textfield that dissapears when the user clicks on it

    - by John Smith
    In HTML & JS, how do you make a textfield that has grayed out text telling the user what the field is for that goes away when the user clicks on the field? For example, in firefox the search field in the top right hand side says which search engine it uses when there's nothing entered, then once you click it's an empty textfield, but if you leave it blank and remove focus from the textfield then the grayed out text is back again. Is there a name for this behavior? Also, is it possible to do in pure css without the use of js to do the on focus / on blur events?

  • current transform being applied by canvas

    - by Allain Lalonde
    How can I determine the current transform that's being applied by an html5 canvas. It seems that it only supports two methods for dealing with transforms "transform", "setTransform" but I can't seem to discover the results of applying the transforms. Short of tracking them all myself and duplicating the the matrix mathematics that it must be doing natively, how can I figure out the current transform?
