Unobtrusive Javascript onclick

由 三世轮回 提交于 2021-02-07 03:47:05
问题 I was recently reading on Unobtrusive javascript and decided to give it a shot. Whether or not I decide to use this style is to be determined at a later time. This is just for my own curiosity and not for any time restricted project. Now, I was looking at example code and a lot of the examples seem to be using, what took me forever to discover, jQuery. They use a function like $('class-name').whatever(...); Well I rather like the look of $('class').function, so I tried to emulate it without

How to troubleshoot silently failing js in Rails?

由 六眼飞鱼酱① 提交于 2020-01-15 06:26:08
问题 It should be noted that I am not very proficient at using Firebug, but I haven't found any errors that explain the following issue. I have a feed.js.erb file containing the following code: var $foos = $('<%= escape_javascript(render(@foos)) %>'); $('#container').append($foos); $('#pagination_button a').attr('href', '<%= feed_path + '?page=' + @page %>'); When this ajax call is made the second time , it appears to fail silently. I see the appropriate response in the Firebug console, but $foos

问题 Google hasn't yielded satisfactory results. I'd appreciate it if people can provide some suggestions.

问题 In my Rails app, I have a form that is loaded via Ajax using jQuery load method. function load_sales_form(product_id) { $("#sales_form").load("<%= url_for(:action => :show_sales_form) %>"/ + product_id); } The loaded form has a form_for tag with the :remote => true option and it does add the data-remote="true" attribute to the form. But the form isn't submitted using Ajax when the user clicks the submit tag button. It works fine if the form is loaded in the standard, non-ajax way, but it the

Asp MVC unobtrusive Client Validation always returning true

由 三世轮回 提交于 2020-01-01 10:59:11
问题 We have a partial view that contains a form with unobtrusive client validation enabled. If we load the partial view using Html.Action, the validation works on the client side. If when the user clicks a link we use JQuery to populate a div with the partial view , the client validation always returns true. Any idea what is going on? 回答1: You need to parse the new html to hook up the validation controls. You can do this using: $.validator.unobtrusive.parse( $('.selector' ) ); where the selector

问题 I am using Ruby on Rails 4. In my previos question I asked about how to handle JavaScript events of a link_to :remote element "a là Rails Way". However I would like to make the AJAX to do not evaluate the JavaScript response (whatever it is) so that I can implement my custom behaviors. In my case the AJAX response that should be ignored is generated by clicking the following link: link_to('destroy', article_path(@article), :method => :delete, :remote => true, :id => 'css_id') On success it

when is the Javascript event loop triggered in a HTML page?

由 两盒软妹~` 提交于 2019-12-25 03:25:47
问题 I'am aware that the JS function (i.e. setTimeout(function(){...}, TIME)) places the function it received as a parameter in the Browser's event loop, and that this event loop will be processed after all inline/synchronous JS call are processed. But what actually happens when he have the following HTML page structure: <html> <head> <script> MANY INLINED SCRIPTS </script> <script src="file.js"></script> <script> setTimeout(function(){...}, TIME)</script> . . . and the page goes, with probably

How to properly use javascript-links for users without js

由 时光毁灭记忆、已成空白 提交于 2019-12-25 02:08:54
问题 I hope I'm not creating a duplicate here, but I just don't really know what to look for/didn't find anything useful yet. I got several links ( <a> ) on my page that trigger the jquery click() handler, which will load a new page into a div without reload. To make those links available to non-javascript users, I want to link them to the same page (that's why I'm using s and not just any div/span/button). Propblem with that is that the script will reload anyway, so you can say jaavascript is

问题 I have a variable length array of strings declared in javascript that contains Dungeons and Dragons class names. An example of this is below: var class_names = new Array("Wizard", "Wizard", "Wizard", "Sorcerer", "Sorcerer", "Ultimate Magus"); In my HTML, I use the javascript window.onload function to set a variety of variables from the javascript file to build the content of the page being displayed locally.
