I'm having a problem getting the back button function to work in Rhomobile.
I've tried various methods of url_for(:index, :back => ....) etc etc and nothing seems to work. The problem with this method is (even if it worked) that it only allows navigation to a set place, rather than a dynamic history/back navigation.
The closest I've come to a working solution is by using this in the application_helper:
def page_back
WebView.navigate_back
end
and then Back in the view.
This works, and i can navigate across views and even controllers. However, it generates a "Error loading page" error, even though it does actually render the right page...
Does anybody have any ideas?
Ok this is what I did in the end. I've decided against using rhodes now but here is what I came up with for this problem:
Added data-add-back-btn="true" to:
<div data-role="page" data-add-back-btn="true">
Then:
<div data-role="header" data-position="inline">
<h1>Title</h1>
Back
</div>

I have a html form inside one of my views that is supposed to get an image the user uploads and save it, the form is below:
<form class="col-lg-12" action="/banner/store/">
The form itself is quite large, but later on there's a to end it. It was supposed to redirect me to the banner/store where my Banner controller have a dd() function so I can confirm everything is okay. But instead, I get a blank white screen and the url goes banner/store/?.
The routes to the BannerController seems to be correct since banner/create works, the problem is when I go from create to store, but anyways, here's how I set the Routes:
Route::resource('banner', 'BannerController');
Any ideas why my banner/store won't work? And why is there a question mark on the end of the url? Sorry if this may be a dumb error, I'm still learning coding.
Your action is is wrong. When you use the resource static method then the store-url is the same as the GET url.
You can achive your goal with:
<form class="col-lg-12" action="{{ route('banner.store') }}" method="POST">
See more information in documentation.
When you updating your banner, you can't use the browser native form with PUT.
See in this document how laravel will handle that for you.
I'm doing a browser check and trying to display a warning message if the person is using a browser that is not compatible(IE 8 and less), believe me, there are people using it where i work
The problem i'm having is i cannot seem to hide the #Render of the page
My if statements are all kicking in fine, and i have wrapped the #Render with a div and i'm trying to hide it based on the conditions i get, like so
else {
$("#yourMessage").show();
$("#content").hide();
}
HTML
<div id="content">
#RenderBody()
</div>
<div id="yourMessage" hidden="hidden">Some Message</div>
Is there something built in to MVC to stop me from being able to do this?
I'm working on a news publishing site that needs to load in stories from an RSS feed below the current news page. I've been using InfiniteAjaxScroll (http://infiniteajaxscroll.com/) to some success however, I've hit a brick wall. There is not way for me to dynamically change what story should load in next as you scroll down the page.
Does anyone know of any other plugins, tutorials, examples that replicate behavior like this. I've searched but come up with nothing that meets these requirements.
I'm trying to create something similar to what the Daily Beast has implemented on their site.
http://www.thedailybeast.com/articles/2014/11/05/inside-the-democrats-godawful-midterm-election-wipeout.html
How do they know what stories to load in?
Thanks!
If you're using the InfiniteAjaxScroll library, the "next story" is whatever link you define as the next URL which can be dynamic for each story you load.
Imagine your first story's HTML as something like this
<div class="stories">
<div class="story">
...
</div>
</div>
<div id="pagination">
next
</div>
Then in the storyC.html you have
...
<div id="pagination">
next
</div>
Assuming you're using some sort of dynamic backend, you would use some sort logic to grab a related story and just set that URL as the "next" URL.
I have this problem I'm facing. I have been working on a project using Grails based on the advice from a friend. I'm still a novice in using Grails, so any down to earth explanation would be highly welcomed.
My project is a web application which scans broken or dead links and displays them on a screen. The main application is written in Java, and it displays the output (good links, bad links, pages scanned) continuously on the system console as the scan goes on. I've finished implementing my UI, controllers, views, database using Grails. Now, I will like to display actively in a section of my GSP page say forager.gsp the current link being scanned, the current number of bad links found and the current page being scanned.
The attempts I have tried in implementing this active display include storing the output my application displays on the console in a table in my database. This table has a single row which is constantly updated as the current paged scanned changes, number of good links found changes and number of bad links found changes. As this particular table is being updated constantly, I've written an action in my controller which reads this single line and renders the result to my UI. The problem I'm now facing is that I need a way of constantly updating the result being displayed after an interval of time in my UI. I want the final output to look like
scanning: This page, Bad links: 8, good links: 200
So basically here is my controller action which reads the table from the database
import groovy.sql.Sql
class PHPController {
def index() {}
def dataSource
def ajax = {
def sql = new Sql(dataSource)
def errors = sql.rows("SELECT *from links")
render (view: 'index', template:'test', model:[errors:errors])
}
}
Here is the template I render test.gsp
<table border="0">
<g:each in="${ errors }" var="error">
<tr><td>${ error.address }</td><td>${ error.error}</td><td>${ error.pageLink}</td></tr>
</g:each>
</table>
For now I'm working with a test UI, which means this is not my UI but one I use for testing purposes, say index.gsp
<html>
<body>
<div><p>Pleaseeee, update only the ones below</p></div>
<script type="text/javascript">
function ClickMe(){
setInterval('document.getElementById("auto").click()',5000);
alert("Function works");
}
</script>
<div id="dont't touch">
<g:formRemote url="[controller:'PHP', action:'ajax']" update="ajaxDiv"
asynchronous="true" name="Form" onComplete="ClickMe()" after="ClickMe()">
<div>
<input id="auto" type="button" value="Click" />
</div>
</g:formRemote>
<div id="ajaxDiv">
<g:render template="/PHP/test"/>
</div>
</body>
</html>
The div I'm trying to update is "ajaxDiv". Anyone trying to answer this question can just assume that I dont have an index.gsp and can propose a solution from scratch. This is the first time I'm using Grails in my life so far, and also the first time I'm ever dealing with ajax in any form. The aim is to dynamically fetch data from my database and display the result. Or if someone knows how to directly mirror output from the system console unto the UI, that will also be great.
It sounds like a form would be appropriate for your needs. Check out the Grails documentation on forms. You should be able to render a form with the values you would like without too much trouble. Be sure to pay attention to your mapping and let me know if you have any questions after you have set index.gsp up to render a form for your values.
I have DateFrom and DateTo fields. I want to submit those data to action which will do some business logic but nothing changes on the original GSP, and nothing is updated. How do I manage this? I've tried this:
<g:formRemote name="formName" url="[action: 'myAction']">
Everything is fine but except my action tries to render myAction.jsp.
This is a great place to read how it works.
Basically you need to specify what controller as well:
<g:formRemote name="formName" update="updateMe" url="[controller: 'controller', action:'myAction']">
The "updateMe" is the id of an html-object, preferably div, that you want to alter after submit (but it's not mandatory). It also uses the actionName.gsp to "supply" the answer, this is why you need to have this page create as well.
Remote forms are a bit tricky in the beginning, but they're super simple once you get a hang of it!
This is how I did it:
GSP:
<g:formRemote name="formName" update="updateMe" url="[controller: 'controller', action:'myAction']">
<div id="updateMe">
<g:render template="updateTemplate"/>
</div>
Action:
...
render template:"updateTemplate"
updateTemlate and updateMe div are both empty.
If you have better solution please tell me.
you can use remoteFunction
you need to write submit button inside form and then after it will fire action and some changes shown into div..
