I am trying to decorate my background of my website I am building and for some reason I can put one or the other by themselves work but when I add both lines then only the top one works. How can I make both lines work together.
<body style=background-color:powderblue>
<body style=border-style:solid;border-color:red>
You can only have one <body> tag.
<body style="background-color:powderblue;border-style:solid;border-color:red">
Combine the styles into one, or move the styles to a css file or <style> block in your <head>
body {
background-color:powderblue;
border-style:solid;
border-color:red
}

I am generating a pdf document using react-native-html-to-pdf.
When the document contains a long list of elements it is possible for some elements to span two pages within the same document.
For example this simple html:
<html>
<head></head>
<body>
<section style="border:solid 1px black;"><p>item</p></section>
<!-- sections repeat 32 times omitted for brevity -->
</body>
</html>
I get a document that looks like this at the page break:
How can I control this? Does it depend on the html elements in the document?
What I know about getElementsByClassName / getElementsByTagName is that both create a nodelist of the elements in question and that the nodelist elements are treated as objects I have a problem where I want to display the innerHTML of the elements inside of the nodelist but because they are objects this seems to be impossible.
Example:
<!DOCTYPE html>
<head>
<link rel="stylesheet" type="text/css" href="stylesheet.css">
<script src="javascript.js"></script>
</head>
<body>
<p id="pp"></p>
<button onclick="test()">push to test</button>
<p>dog</p>
<p>cat</p>
<p>snake</p>
</body>
//javascript.js file
function test() {
var paragraph = document.getElementsByTagName("p"),
para1 = paragraph[0].innerHTML,
ansBox = document.getElementById("pp");
ansBox.innerHTML = para1;
}
This is condensed version of a longer code. I think that the para1 variable should be a string and then the assignment statement should assign that string to the ansBox.innerHTML but instead I get nothing. I have reworked several versions of this code none work. How can you get the text elements inside of a nodelist to display in the ansBox?
Your script is loaded but your DOM hasn't loaded yet if you load your script inside head like that
<!DOCTYPE html>
<head>
<link rel="stylesheet" type="text/css" href="stylesheet.css">
</head>
<body>
<p id="pp"></p>
<button onclick="test()">push to test</button>
<p>dog</p>
<p>cat</p>
<p>snake</p>
<script src="javascript.js"></script> <!-- load it here -->
</body>
Also paragraph[0] and ansBox refer to the same DOM HTMLParagraphElement just so you know which does not have anything inside (It is empty to begin with)
In the JavaScript code above, you took the HTML inside an empty element and then assign it to itself, and of course you get an empty value.
I want to be able to display a content item of a certain type and only that content item i.e. no shapes that are not part of said item.
I have tried creating a controller method with a {Themed(false)] attribute, or returning a partial view. Both of these do almost exactly what I want, except that these don't include any scripts or styles associated with the View I'm trying to display.
My current attempt look like this:
Controller method:
[Themed(false)]
public ActionResult DisplayBare(int id) {
var contentItem = _contentManager.Get(id, VersionOptions.Published);
dynamic model = _contentManager.BuildDisplay(contentItem);
return View( (object)model);
}
The DisplayBare view:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
#Display(Model)
</body>
</html>
The problem is that when the display View of an item includes Script.Require, Script.Include and Script.Foot directives, the scripts do not show up in the Html.
How would I achieve this?
Found a solution by snooping around Orchard sources:
Using this view to display my content item gives me exactly what i want:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
#{
Style.Include("Site.css");
var content = Display(Model);
}
#Display.Metas()
#Display.HeadScripts()
#Display.HeadLinks()
#Display.StyleSheetLinks()
</head>
<body>
#content
#Display.FootScripts()
</body>
</html>
I'm trying to add id to a element using dojo.query. I'm not sure if it's possible though. I trying to use the code below to add the id but it's not working.
dojo.query('div[style=""]').attr("id","main-body");
<div style="">
content
</div>
If this is not possible, is there another way to do it? Using javascript or jquery? Thanks.
Your way of adding an id to an element is correct.
The code runs fine for me in Firefox 17 and Chrome 23 but I have an issue in IE9. I suspect you may have the same issue.
In IE9 the query div[style=""] returns no results. The funny thing is,it works fine in compatibility mode!
t seems that in IE9 in normal mode if an HTML element has an inline empty style attribute, that attribute is not being preserved when the element is added to the DOM.
So a solution would be to use a different query to find the divs you want.
You could try to find the divs with an empty style attributes OR with no style attribute at all.
A query like this should work:
div[style=""], div:not([style])
Take a look at the following example:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Test Page</title>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/dojo/1.8.2/dojo/dojo.js"></script>
<script type="text/javascript">
dojo.require("dojo.NodeList-manipulate");//just for the innerHTML() function
dojo.addOnLoad(function () {
var nodeListByAttr = dojo.query('div[style=""], div:not([style])');
alert('Search by attribute nodeList length:' + nodeListByAttr.length);
nodeListByAttr.attr("id", "main-body");
var nodeListByID = dojo.query('#main-body');
alert('Search by id nodeList length:' + nodeListByID.length);
nodeListByID.innerHTML('Content set after finding the element by ID');
});
</script>
</head>
<body>
<div style="">
</div>
</body>
</html>
Hope this helps
#Nikanos' answer covers the query issue, I would like to add, that any query returns an array of elements, in case of Dojo it is dojo/NodeList.
The problem is you are about to assign the same id to multiple DOM nodes, especially with query containing div:not([style]). I recommend to use more specific query like first div child of body:
var nodes = dojo.query('body > div:first-child');
nodes.attr("id", "main-body");
To make it more robust, do not manipulate all the nodes, just the first node (even through there should be just one):
dojo.query('body > div:first-child')[0].id = "main-body";
This work also in IE9, see it in action: http://jsfiddle.net/phusick/JN4cz/
The same example written in Modern Dojo: http://jsfiddle.net/phusick/BReda/
With StringTemplate, what is the proper way to have a standard layout template such as:
<head>
..
</head>
<html>
$body()$
</html>
Where I can set the body template from my application, so that every template I use uses this fundamental layout?
Thanks.
I found it hiding in the documentation:
http://www.antlr.org/wiki/display/ST/StringTemplate+2.2+Documentation
"Include template whose name is
computed via expr. The argument-list
is a list of attribute assignments
where each assignment is of the form
attribute=expr. Example
$(whichFormat)()$ looks up
whichFormat's value and uses that as
template name. Can also apply an
indirect template to an attribute."
So my main layout template now looks like this:
<head>
<title>Sportello</title>
</head>
<html lang="en-US">
<body>
$partials/header()$
<section>$(body_template)()$</section>
$partials/footer()$
</body>
</html>
...to which I pass the subtemplate's name as an attribute.
