I am using bootstrap-treeview 1.2.0 (from Jon Miles).
My goal is to add custom data-attributes to my list items' markup, e.g.
<li class="list-group-item node-tree" data-id="100" data-type="user" ...>
I tried to follow these instructions see here and here is part of my JSON:
[{"text":"Root","icon":null,"data-id":1,"data-type":"branch","nodes":[{"text":"Steve","icon":null,"data-id":17, "data-type":"user","nodes":...
To me the JSON looks good. But none of my data-attributes gets rendered in the markup.
Any ideas?
Sorry, I see it's too late. I searched about this and couldn't find anything. But you can
change bootstrap-treeview.js file a bit. There is some attribute set code in buildTree function. It's looking like this:
Tree.prototype.buildTree = function (nodes, level) {
if (!nodes) return;
level += 1;
var _this = this;
$.each(nodes, function addNodes(id, node) {
var treeItem = $(_this.template.item)
.addClass('node-' + _this.elementId)
.addClass(node.state.checked ? 'node-checked' : '')
.addClass(node.state.disabled ? 'node-disabled': '')
.addClass(node.state.selected ? 'node-selected' : '')
.addClass(node.searchResult ? 'search-result' : '')
.attr('data-nodeid', node.nodeId)
.attr('style', _this.buildStyleOverride(node));
......................SOME CODES ........SOME CODES..........................}
You can add :
.attr('data-type', node.dataType)
.attr('data-id', node.dataId)
And then change the object(json) like this:
[{"text":"Root","icon":null,"dataId":1,"dataType":"branch","nodes":
[{"text":"Steve","icon":null,"dataId":17, "dataType":"user","nodes":...
The link provided simply instructs how to expand the node object with additional properties. There is no correlation between a node's properties and the attributes assigned in HTML.
You might want to do something like this:
var allNodes = $('#tree').treeview('getNodes);
$(allNodes).each(function(index, element) {
$(this.$el[0]).attr('data-attribute-name', this.data-attribute-name);
});

I've implemented code inside a ckeditor that replaces the src attribute of iframe elements with data-src and adds the data-cookieconsent attribute. In addition, a placeholder div is added after the iframe element. Regex is used to match the iframe elements in the string.
var value = CKEDITOR.instances.editor1.getData();
const regex = new RegExp('(?:<iframe[^>]*)(?:(?:\/>)|(?:>.*?<\/iframe>))');
const matches = value.match(regex);
if (typeof matches !== "undefined" && matches != null) {
matches.forEach(element => {
if (!element.includes("data-cookieconsent")) {
value = value.replace(element, element.replace("src=", "data-add-placeholder data-cookieconsent=\"marketing\" data-src="))
value = value.replace("</iframe>", "</iframe><div class=\"row justify - content - center\">" +
"<div class=\"cookieconsent-optout-marketing blocked-media-placeholder\">" +
"<div class=\"col-xs-6 col-xs-offset-3\">" +
"<h3>For at se denne video skal vi bruge dit samtykke til at anvende cookies.Venligst tryk på dette link og vfremvist denne video.</h3>" +
"</div></div></div>")
}
});
}
However, I now need to replace the currently existing iframe elements and add the placeholder div in the database using sql. I'm aware that I can use update with the replace function to update parts of a text column, but this seems to require Regex to work, which as I understand, is quite limited in T-SQL.
What would be the best approach to this problem? How can I ensure only the iframe elements in the column are altered?
Following the answer on this post I was using #:<div class="col-md-6">
Problems
The Formatting gets all messed up:
The intellicode gets all messed up (I only deleted the paragraph on the second #:)
Also, my if (i == (Model.CellsNotStarted.Count - 1) && i % 2 != 0) won't work when using the #:; it will always go on the else. If I don't use the #: markup, and if I, for instance put all my html in a if/else instead of only the <div> tag it will work with no problems.
My question is:
Is the #: markup viable? If so, what am I doing wrong. If not what is the alternative (that does not imply putting my entire code in an if/else)
PS: I know I should not post images of code, but I wanted to show the format and syntax errors.
There are neater ways to manage conditions within your Razor code. It's difficult to provide a full example because you don't provide the full code, but you can do this, for example:
<div class="col-md-#(i+1 == Model.CellsNotStarted.Count && i % 2 ! = 0 ? "12" : "6")">
Whenever you are tempted to use a remainder operator (%) in Razor, you should also consider whether a GroupBy would be better. It most often is, as I was shown in this question: Building tables with WebMatrix
You can try to use js to set html.Here is a demo:
<div id="myDiv"></div>
<script>
$(function () {
var html = "";
if ("#(Model.CellsNotStarted != null)"=="True")
{
for (var i = 0; i <#Model.CellsNotStarted.Count; i++)
{
if (i == (#Model.CellsNotStarted.Count - 1) && i % 2 != 0)
{
html += '<div class="col-md-12">';
}
else
{
html += '<div class="col-md-6">';
}
html += i+'</div>';
}
}
$("#myDiv").html(html);
})
</script>
result:
I have a Grid.
Get Data Code
Code:
var myParam = {
typeId : 1,
xxxx : 'xxxx' //some else
}
grid.store.load(myParam);
When to do something such as time renovate
Code:
grid.store.reload();
But this lost param.
In ExtJs3 have a Config of LastParam .
How to do in Extjs4.
thanks.
use the proxy's extraParams config.
grid.store.getProxy().extraParams = myParam;
grid.store.load();
grid.store.reload();
This way the params will be sent until you modify the extra param again with code.
i need to scrape a p tag which has h3 tag after it but does not have a closing p tag. It looks like this :
<script ad>asdasdasd</script>
<p>Translation companies are
-----------------------
-----------------------
<h3 class="this_class">mind blown site</h3>
There is no </p> tag so i cannot parse it completely. Now i have two questions :
1) can this be parsed using httpagility xpath ?
2) i have a function to find text between two strings (getbetween). But i have a doubt - If i use "asdasdasd" and " is it always 100% that vb.net will use the script tag which is just above h3 because there are 2-3 same lines - "asdasdasd"
3) Any other method you guys are aware of ?
(had to write in code so html does not mess up)
Regards,
It might be a good idea to post some more "real" html to really help you, at least the tags between the h3 and the p.
Anyway, this should get you the p-Tag from the h3-Tag.
HtmlDocument doc = new HtmlDocument();
doc.Load(... //Load the Html...
//Either of these lines will do
HtmlNode pNode = doc.DocumentNode.SelectSingleNode("//h3[#class='this_class']/preceding-sibling::p");
//HtmlNode pNode = doc.DocumentNode.SelectSingleNode("//h3[contains(text(),'mind blown site')]/preceding-sibling::p");
string pInnerHtml = pNode.NextSibling.InnerHtml; //Has the text "Translation companies are...."
So in general, to get all the nodes from the opening p tag to the start of a tag you don't want, you could do this:
var p = doc.DocumentNode.SelectSingleNode("//p");
var h3 = p.SelectSingleNode("following-sibling::h3[#class='this_class']");
var following = new List<string>();
for (var current = p.NextSibling; current != h3; current = current.NextSibling)
{
following.Add(current.InnerText);
}
var innerText = String.Concat(following);
I saw this question already, but I didnt see an answer..
So I get this error:
The ':' character, hexadecimal value 0x3A, cannot be included in a name.

All I want is to get the "http://global.fncstatic.com/static/managed/img/Politics/panetta_hearing_030712.jpg", and before that check if content:encoded exists..
Thanks.
EDIT:
I've found a sample that I can show and edit the code that tries to handle it..
EDIT2:
I've done it in the ugly way:
text.Replace("content:encoded", "contentt").Replace("xmlns:content=\"http://purl.org/rss/1.0/modules/content/\"","");
and then get the element in the normal way:
MediaContent = feed.Element("contentt").Value
The following code
static void Main(string[] args)
{
var XMLFeed = XDocument.Parse(

A few points:
You never want to treat Xml as text - in your case you removed the namespace declaration but actually if the namespace was declared inline (i.e. without binding to the prefix) or a different prefix would be defined your code would not work even though semantically both documents would be equivalent
Unless you know what's inside CDATA and how to treat it you always want to treat is as text. If you know it's something else you can treat it differently after parsing - see my elaborate on CDATA below for more details
To avoid NullReferenceExceptions if the element is missing I used explicit conversion operator (string) instead of invoking .Value
the Xml you posted was not a valid xml - there was missing namespace Uri for feedburner prefix
This is no longer related to the problem but may be helpful for some folks so I am leaving it
As far as the contents of the encode element is considered it is inside CDATA section. What's inside CDATA section is not an Xml but plain text. CDATA is usually used to not have to encode '<', '>', '&' characters (without CDATA they would have to be encoded as < > and & to not break the Xml document itself) but the Xml processor treat characters in the CDATA as if they were encoded (or to be more correct in encodes them). The CDATA is convenient if you want to embed html because textually the embedded content looks like the original yet it won't break your xml if the html is not a well-formed Xml. Since the CDATA content is not an Xml but text it is not possible to treat it as Xml. You will probably need to treat is as text and use for instance regular expressions. If you know it is a valid Xml you can load the contents to an XElement again and process it. In your case you have got mixed content so it is not easy to do unless you use a little dirty hack. Everything would be easy if you have just one top level element instead of mixed content. The hack is to add the element to avoid all the hassle. Inside the foreach look you can do something like this:
var mediaContentXml = XElement.Parse("<content>" + (string)item.MediaContent + "</content>");
Console.WriteLine((string)mediaContentXml.Element("img").Attribute("src"));
Again it's not pretty and it is a hack but it will work if the content of the encoded element is valid Xml. The more correct way of doing this is to us XmlReader with ConformanceLevel set to Fragment and recognize all kinds of nodes appropriately to create a corresponding Linq to Xml node.
You should use XNamespace:
XNamespace content = "...";
// later in your code ...
MediaContent = feed.Element(content + "encoded")
See more details here.
(Of course, you the string to be assigned to content is the same as in xmlns:content="...").
