Javascript non-blocking scripts, why don't simply put all scripts before </body> tag?

由 风流意气都作罢 提交于 2019-11-29 12:17:02
问题 In order to avoid javascript to block webpage rendering, can't we just put all all our JS files/code to be loaded/executed simply before the closing </body> tag? All JS files and code would be downloaded and executed only after the all page has being rendered, so what's the need for tricks like the one suggested in this article about non blocking techniques to load JS files . He basically suggests to use code like: document.getElementsByTagName("head")[0].appendChild(script); in order to

Defer loading of JavaScript - Uncaught ReferenceError: $ is not defined

由 爱⌒轻易说出口 提交于 2019-11-29 11:42:58
I use google code to defer loading javascript ( google pages ) But I have some inline javascripts such as: <script type="text/javascript"> $(function () { alert("please work"); }); </script> And this gives me: Uncaught ReferenceError: $ is not defined I think I need some function, which was triggered after jQuery was loaded and init my inline javascripts. But if there is another way, I will be glad. EDIT: Some of you are completely out of topic. Mahesh Sapkal was close. With this code I have no error, but still don't work <head> <script type="text/javascript"> var MhInit = NULL; // Add a

I am using ASP.NET MVC 4 application. Home controller’s constructor is parameterized with 2 parameter(Iservice1 service1, Iservice2 service2) Not all the code path uses any of the Service (service1, service2), only in some code path I need service1 instance/object or service2 instance/object. I don’t want to use container.Resolve< <Lazy<IService1> >(); From this link ( http://msdn.microsoft.com/en-us/library/dn178463(v=pandp.30).aspx ) I understood that unity.mvc 4 use unity 3 which has Lazy loading support, but how to do this in ASP.NET MVC 4. In general, instance constructors should do

Understanding jQuery Deferred.pipe()

由 吃可爱长大的小学妹 提交于 2019-11-28 07:30:17
I am trying to implement the jQuery Deferred.pipe() method for the following scenario: Add a user in DB via $.ajax() Get response whether user was added correctly or not. If successfully added, get all the user list from server via $.ajax() Display the list via jQuery templates This is something which I tried: var addUserSuccess = function( data ) { if ( data.returnCode !== "success" ) { return $.Deferred().reject('Error saving user'); } getUsers(); } var addUser = function() { return $.ajax(url, { type: "POST", data: { username: 'test' }, contentType: "application/json", dataType: "json" });

Speed up page load by deferring images

由 做~自己de王妃 提交于 2019-11-28 05:22:30
I am creating a page which will contain a lot of large sized images, so naturally I want to make sure the page loads without too much trouble. I read this article here http://24ways.org/2010/speed-up-your-site-with-delayed-content The method of deferring is as follows (pulled from page, don't mind the URL) <div> <h4> <a href="http://allinthehead.com/" data-gravatar-hash="13734b0cb20708f79e730809c29c3c48"> Drew McLellan </a> </h4> </div> then later a snippet of js takes care of the image loading $(window).load(function() { $('a[data-gravatar-hash]').prepend(function(index){ var hash = $(this)
