The Leaf documentation doesn't seem to be working for me I can't figure out why.
child.leaf
#extend("index"):
#export("hello"):
<p>Welcome to Vapor!</p>
#endexport
#endextend
index.leaf
<!-- Backend Projects -->
<div class="seciton-label">
<h3>#(.backendCollection.title)</h3>
</div>
#import("hello")
<!-- Backend Card -->
#for(card in .backendCollection.collection):
<div class="greeting-card">
<a href=#(card.url)>
<h3>#(card.title)</h3>
</a>
<p> #(card.description) </p>
</div>
#endfor
The following image is the result I get in localhost
Request result running the vapor server on localhost
Please help - I can't find solutions to this issue.
No response from forums.swift.org
Tried removing the import key
Removing quotes
I saw individuals using the following format in older versions of Vapor. This did not work for me either.
<!-- I tried the following format for the extend and export blocks -->
#extend("index") {
#export("hello") {
<p>Welcome to Vapor!</p>
}
}
I'm trying to be able to extend the leaf templates and understand why the html does not render.
This works and does something similar to what you want.
This is my 'template' (heavily simplified here), called Base.leaf:
<!DOCTYPE html>
<html>
<head>
<title>#(title)</title>
</head>
<body>
#import("body")
</body>
</html>
#extend("Build/Message")
</body>
</html>
The extend of Build/Message above behaves simply like an include.
Then I use it in a form called Login.leaf here:
#extend("Build/Base"):
#export("body"):
<form method="POST" action="/log-in">
<label for="email">Email</label>
<input type="text" name="email" required>
<label for="password">Password</label>
<input type="password" name="password" required>
<button class="btn-success">Log-in</button>
</form>
#endexport
#endextend
I then use the `Login.leaf' in a render such as:
let context = ["title": "Log in", "version": C.Msg.Version, "message": request.getMessage()]
return try await request.view.render("Form/Login", context)

Above is the code for which i want to write Xpath using tag name traversal. Here is the xpath i have made
"//div[#id='reg_form_box']/div[1]/div[1]/div[1]/div/input"
Please suggest what's wrong here and how can i correct the same. Website is Facebook and field is First name on homepage.
Ideally unless you have a case of multiple modes that match the same xpath, you don't have to traverse through the entire hierarchy.
This will work:
//input[#name='firstname']
I have a form with multiple description text fields, file chose field and submit button for the Cross-Domain request (CORS variant):

The Node.js (Express.js) server has a route:
app.post('/upload/:id', function(req, res){
console.log(req.fields);
...
});
The problem is, I can not find the data from input fields: req.fields gets undefined.
How can I find the data (text description and a file) from the req on the server?
Update:
Great! req.body really get access to all the fields, BUT:
console.log(req.body)
prints:
{ description_title: 'aaa',
description_author: 'bbb',
description_tags: 'ccc',
description_textarea: 'ddd',
upload: '' }
but where is the fileData field? I mean, where the file I upload with the description (aforementioned fields)?
Update 2: Done!
Files are not in the body attribute, but in the req.files
Thanks for Adam and andyfan!
As said by Adam if you see these two lines
app.use(express.bodyParser());
app.use(express.methodOverride());
in app.js file of express, then you can read fields as given below.
app.post('/upload/:id', function(req, res){
console.log(req.body.description_title);
console.log(req.body.description_author);
console.log(req.body.description_tags);
console.log(req.body.description_textarea);
console.log(req.files);
res.send("Done!");
});
You can read more about how to handle files in express at this link http://howtonode.org/really-simple-file-uploads
You want req.body so long as you have express.methodOverride() in your configuration before the routes.
In your route try console.log(req.body); to see what object you get there. For the route parameters it is req.params.
console.log(object); can be your best friend when trying to find the objects your looking for and the data structure they are contained in.
I want to update the value from a input/textfield with a calculated value from the cookie.It's like a mini local cookie cart.
Saving and retrieving the json from the cookie is a piece of cake.
In my behavior I fail to make the following work:
I added a class for every node in the input field, it's constructed like the example below.
Myid = 'webform_cart_nid_10';
formElement = $('.' + Myid);
console.log(formElement);
The html is quite nested and can be seen http://it2servu.be/broodjes/bestellen (if I may link?) .
the field whose value I want to update looks like this:
<input class="webform_cart_nid_10 webform_cart_nid form-text" type="text" id="edit-submitted-cart-item-cart-elements-10" name="submitted[cart_item][cart_elements][10]" value="0" size="3" maxlength="128">
Is contained in drupal output with severe div-itis.
<div class="page clearfix" id="page">
<div id="section-content" class="section section-content">
<div id="zone-content-wrapper" class="zone-wrapper zone-content-wrapper clearfix">

probably it's something stupid, I just can't figure out what it is?
Your problem is with jQuery. If you pop open the console in Chrome and type jQuery, it returns the jQuery function. If you type $ it returns undefined. You have some sort of collision causing $ not to be set to jQuery.
use "jQuery" instead of "$"
Myid = 'webform_cart_nid_10';
formElement = jQuery('.' + Myid);
console.log(formElement);
the "$" never worked for me in Drupal 7.
I'm writing a mobile app with PhoneGap and jQuery Mobile. To simplify navigation I want to spread a single form over multiple 'pages' using div data-role="page". The idea is to give the user a wizard like experience for filling in a large form. On completion I need to be able to save the form locally, or submit it, if the mobile is online.
I don't understand how to go about submitting or saving a form using jQuery Mobile if the form is split into multiple 'virtual' pages. I've search the web but can't find any tutorials or examples on solving this problem.
Any help will be appreciated.
UPDATE:
I recently changed the way I worked with multipage forms, and this solution worked nice for me. You basically use a naming convention where fields become part of sections by giving them id's starting with the section name and a dash, e.g: person-name, person-surname. See the answer below.
Ok, I posted my thoughts here: http://www.coldfusionjedi.com/index.cfm/2011/11/18/Demo-of-a-multistep-form-in-jQuery-Mobile
Essentially I ended up using a sever side language to simply include the right part of the form at a time. (I'm using ColdFusion, but any language would work really.) The form self posts and simply displays the right step based on where you are in the process.
A quick help to anyone stuck with the same problem. I did the 'form thing', but it gets sloppy. You basically just embed the page divs inside the form element, but that's not very elegant and has given me some navigation issues.
So I ended up with my own solution that works over huge multipage forms (+/- 1000 elements). Not the most elegant, but it works like a charm:

alert(JSON.stringify(readFormData('dates')));
});
});
function readFormData(section) {
var sectionData;
var els = $(':input[id|='+section+']');
var sectionData = {};
$.each(els, function() {
if (this.name && !this.disabled && (this.checked
|| /select|textarea/i.test(this.nodeName)
|| /text|hidden|password|date|email/i.test(this.type))) {
sectionData[this.name.substr(section.length+1)] = $(this).val();
console.log(this.name + " -> " + $(this).val());
}
});
return sectionData;
}

I have 1 main search form with a submit button and several secondary search forms with submit buttons.
What I would like to do is when I enter text and click on the submit button of the main search form, the same text gets copied in all of the secondary search forms and all the submit buttons of the secondary search forms get automatically hit.
The HTML code for the mains earch form is shown below:
<form action="query.php" method="get">
Search: <input type="text" name="item" size="30">
<input type="submit" value="send">
</form>
One of the several secondary search forms is shown below:
<FORM action="http://www.dpbolvw.net/interactive" method="GET" target="_blank">
<div style="float: left; padding: 0 3px 0 0;">
<INPUT type="text" name="src" size="9"
value="<?php
$input = $_GET['item'];
echo $input;?>" style="width: 110px; height: 22px;margin:0; padding: 0; font-size:140%;">
</div>
<div style="float: left; padding: 0 3px 0 0;">
<input type="image" name="submit" value="GO" src="http://images.guitarcenter.com/Content/GC/banner/go.gif"
alt="Search" style="font-size:140%">
/div>
<input type="hidden" name="aid" value="1234"/>
<input type="hidden" name="pid" value="1234"/>
<input type="hidden" name="url" value="http://www.guitarcenter.com/Search/Default.aspx"/>
</form>
Notice the php code that I put in the "value" field of the secondary search form:
<?php
$input = $_GET['item'];
echo $input;?>
This automatically copies the text that I entered in the main search form into the secondary search form. I thus figured out how to do that.
The problem is to "simulate" an "Enter" keystroke or a click on the "GO" button with the mouse on the secondary search form when the user hits the Enter key or hits the "SEND" button with the mouse on the main search form.
Thank you for your insight!
I'm not sure what the point of that would be, It looks like all of these are search forms all pointing to different sites. Web browsers won't allow that. They can navigate to one page at a time. When you post a form to a page you are navigating to that page. Therefore, you are trying to navigate to several pages at once. It's like trying to be in Paris and London at the same time. I don't see how your plan will work the way you're describing it.
That said, You can use client-side javascript to call
document.forms[0].submit();
so if you can come up with a plan that does not involve trying to have the user see all the different search results in one window, you could try this on your first form...
<form action="query.php" method="get" onSubmit="document.forms(1).Submit();">
You should use AJAX (JQuery) as Brandon Suggested. Read http://docs.jquery.com/Events/submit
Example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
$("#submit").click(function() {
//Do you stuff here like triggering other submits
//Like:
$("input#submit2").click();
$("input#submit3").click();
return false;
});
});
</script>
</head>
<body>
<form action="javascript:alert('success!');">
<div>
<input type="text" />
<input type="submit" id="submit" />
</div>
</form>
<form >
<div>
<input type="text" />
<input type="submit" id="submit2" />
</div>
</form>
<form >
<div>
<input type="text" />
<input type="submit" id="submit3" />
</div>
</form>
</body>
</html>
Take a look at the submit() event in jQuery. That is going to be your key.
I am assuming that you are planning on submitting via ajax? Otherwise it is futile.
So you could do something like this-
Give all of your forms a certain class, let's call it 'ajax_search_forms'. So now you can actually hook into the submit event.
$('.ajax_search_forms').submit(function(){
var search_string = $('input[name=src]').val();
$('.ajax_search_forms').each(function(){
$.ajax({
url : $(this).attr('action'),
data : 'search_string=' + search_string,
success : function(html){
// Do something with the result
}
});
});
// Return false is VERY important so that the form submission does not continue
return false;
});
