To get all the static hyperlinks from another view - javascript

Currently, I am able to get all the hyperlinks from the loaded page in the application. I have added the below code to the shared _Layout page in javascipt.
'''
var links = document.getElementByTagName("a");
var urls=[];
for (var i = 0;i<links.length;i++)
{
var datalink = new Object();
datalink.label=links[i].text;
datalink.value=links[i].getAttribute("href");
if (datalink.value.startswith("https://")) {
urls.push(datalink);
}
}
'''
What I want is that I should also be able to fetch the hyperlinks or the content from the other views (for example /Accounts/Index.cshtml) of the MVC application at the startup.
Any suggestions?

ClickInfo plugin problem on multiple mpld3 charts on same HTML page

I have two matplotlib scatter plot charts (rendered using mpld3.fig_to_html) on the same HTML page. I'm trying to make each point on the chart clickable (to open another window showing more info) using this ClickInfo plugin.
The generated HTML for these charts shows different id's, however the id of one chart gets mixed up with the other when each point is clicked passing the wrong info to the page it opens. There's not much info on how will I restrict search for elements using mpld3.get_element(this.props.id, this.fig);.
If I only have one chart on the same page, this plugin works perfectly.
Would be a great help to have a solution to make this plugin work for this use case.
class ClickInfo(plugins.PluginBase):
JAVASCRIPT = """
mpld3.register_plugin("clickinfo", ClickInfo);
ClickInfo.prototype = Object.create(mpld3.Plugin.prototype);
ClickInfo.prototype.constructor = ClickInfo;
ClickInfo.prototype.requiredProps = ["id","urls"];
function ClickInfo(fig, props){
mpld3.Plugin.call(this, fig, props);
};
ClickInfo.prototype.draw = function(){
var obj = mpld3.get_element(this.props.id, this.fig);
urls = this.props.urls;
obj.elements().on("mousedown",function(d, i){window.open(urls[i], '_blank')});
}
"""
def __init__(self, points, urls):
self.points = points
self.urls = urls
if isinstance(points, matplotlib.lines.Line2D):
suffix = "pts"
else:
suffix = None
print("+++", mpld3.utils.get_id(points, suffix))
self.dict_ = {"type": "clickinfo","id": mpld3.utils.get_id(points, suffix=suffix, prefix='el'),"urls":urls}
Just found out that the version I have (0.5.2) of the mpld3 package has a targets parameter for PointHTMLTooltip that accepts a list of urls, when clicked opens the url on a new window/tab and works perfectly. No need to use ClickInfo.
mpld3.plugins.PointHTMLTooltip(self, points, labels=None, targets=None, hoffset=0, voffset=10, css=None)

Making a checkbox Ui with Google Apps Script

This is my first time posting on Stack Overflow, so I apologize in advance if I made any "posting" mistakes.
I am using Google Apps Script for the project I am doing, because I am interacting with Google Docs and Google sheets. Google Script has a deprecated Ui Service, which is very frustrating to me.
So far, I have written a JavaScript program that parses through the "table of contents" part of a Google Doc, and retrieves the items I wanted. (If the table of content is changed, then the items retrieved might be different too.) Now, my intention is to make a checkbox that uses all the items that I retrieved from the table of contents as its options, and after users choosing and clicking "submit" button, a new Google Sheet would be generated. Of course I will operate on that new Google Sheet, but I want to stick with this problem first.
I did look up HTML Service, a Ui recommended by Google Script, but I don't know too much about HTML. What is most difficult is that if I use HTML to make the checkbox, how am I supposed to get all the items I parsed from the JavaScript passed into the HTML file, check which options are checked, and then get checked options passed back to the JavaScript so that I can do further operation? Is it even possible? Or am I having a misconception?
What I have so far:
//custom menu
function onOpen()
{
var ui = DocumentApp.getUi();
ui.createMenu('Custom Menu')
.addItem('Export Checksheets', 'customMenu')
.addToUi();
}
//parse the table of contents
function readFile()
{
var options = [];
var testDoc = DocumentApp.getActiveDocument();
var file = testDoc.getBody();
var tableOfCon = DocumentApp.ElementType.TABLE_OF_CONTENTS;
var searchRes = file.findElement(tableOfCon);
//If the element exists
if (searchRes)
{
var TC = searchRes.getElement().asTableOfContents();
var numChild = TC.getNumChildren();
for (var i=0; i < numChild; i++)
{
var info = {};
var TCItem = TC.getChild(i).asParagraph();
var TCItemText = TCItem.getChild(0).asText();
var TCItemAttrs = TCItemText.getAttributes(); //for future usage
//get all the options
if (!TCItemText.isBold())
{
options.push(TCItem.getText());
}
}
}
Logger.log(options); //which successfully displays the items retrieved
}
//linked to the HTML file
function customMenu()
{
var html = HtmlService.createHtmlOutputFromFile('Index');
html.setHeight(350).setWidth(280);
var ui = DocumentApp.getUi().showModalDialog(html, 'Hello!');
}
My HTML file only has a little code that displays some message when the custom menu is chosen.
Any help would be appreciated!

vaadin: integrate angular js using custom layout

I tried to integrate angular js application in vaadin by using custom layout like this:
VerticalLayout mainLayout = new VerticalLayout();
mainLayout.setMargin(true);
mainLayout.setWidth("1380px");
setCompositionRoot(mainLayout);
Panel panel = new Panel();
CustomLayout layout = null;
try {
String dynamicHtml = "<div ng-app=\"app\">..........</div>";
layout =
new CustomLayout(new ByteArrayInputStream(dynamicHtml.getBytes()));
} catch (IOException e) {
logger.error("could not create custom layaout", e);
}
panel.setContent(layout);
mainLayout.addComponent(panel);
importJs();
public void importJs() {
String PATH_TO_JS_SCRIPT = jsURL+"?tata=" + new Date();
String script = "try{var fileref=document.createElement('script');";
script += "fileref.setAttribute(\"type\",\"text/javascript\");";
script += "fileref.setAttribute(\"src\", \"" + PATH_TO_JS_SCRIPT +
"\");";
script += "document.getElementsByTagName(\"head
\")[0].appendChild(fileref);}catch(e){alert(e);}";
Page.getCurrent().getJavaScript().execute(script);
}
I import the script js using importJs method.
The first time i access the page, the js file is loaded and it works.
The second time, it does'nt work.
As if the script is not imported.
I don't see what is wrong in my code?
Using Javascript annotation i have the same problem.
I use
vaadin 7.6.5
java 7
Inserting angular code inside CustomLayout is bad idea.
I would recommend to read text: Vaadin and AngularJS - happy together.
There is an add-on available that lets you combine the best of Vaadin and AngularJS: Vaangular
The Js file was only included once and only once during lifecycle of the page.
To excecute this script each time we display the page i use:
if(typeof angular != 'undefined'){
angular.bootstrap(document.getElementById('swdId'), ['app']);"
}
The issue is fixed

Force links to open in a new window

In our web site we have embedded PDFs, and we would like to make sure that when the user clicks a link inside the PDF, it opens in a new tab or window. We have no control over the PDFs so we cannot do anything with the links themselves.
Is it possible to intercept the request in some way, for example with onbeforeunload, and force the new page to open in a separate window?
No sorry, there is no way of doing this.
This is by design.
If it was possible it would be a major security breach.
You can manipulate the links inside the PDF document to run a javascript to open links in a new window/tab. Heres how I did it with C# and iTextSharp
public static MemoryStream OpenLinksInNewWindow(MemoryStream mySource)
{
PdfReader myReader = new PdfReader(mySource);
int intPageCount = myReader.NumberOfPages;
PdfDictionary myPageDictionary = default(PdfDictionary);
PdfArray myLinks = default(PdfArray);
//Loop through each page
for (int i = 1; i <= intPageCount; i++)
{
//Get the current page
myPageDictionary = myReader.GetPageN(i);
//Get all of the annotations for the current page
myLinks = myPageDictionary.GetAsArray(PdfName.ANNOTS);
//Make sure we have something
if ((myLinks == null) || (myLinks.Length == 0))
continue;
//Loop through each annotation
foreach (PdfObject myLink in myLinks.ArrayList)
{
//Convert the itext-specific object as a generic PDF object
PdfDictionary myLinkDictionary = (PdfDictionary)PdfReader.GetPdfObject(myLink);
//Make sure this annotation has a link
if (!myLinkDictionary.Get(PdfName.SUBTYPE).Equals(PdfName.LINK))
continue;
//Make sure this annotation has an ACTION
if (myLinkDictionary.Get(PdfName.A) == null)
continue;
//Get the ACTION for the current annotation
PdfDictionary myLinkAction = (PdfDictionary)myLinkDictionary.Get(PdfName.A);
//Test if it is a URI action
if (myLinkAction.Get(PdfName.S).Equals(PdfName.URI))
{
//Replace the link to run a javascript function instead
myLinkAction.Remove(PdfName.F);
myLinkAction.Remove(PdfName.WIN);
myLinkAction.Put(PdfName.S, PdfName.JAVASCRIPT);
myLinkAction.Put(PdfName.JS, new PdfString(String.Format("OpenLink('{0}');", myLinkAction.Get(PdfName.URI))));
}
}
}
//Next we create a new document add import each page from the reader above
MemoryStream myMemoryStream = new MemoryStream();
using (Document myDocument = new Document())
{
using (PdfCopy myWriter = new PdfCopy(myDocument, myMemoryStream))
{
myDocument.Open();
for (int i = 1; i <= myReader.NumberOfPages; i++)
{
myWriter.AddPage(myWriter.GetImportedPage(myReader, i));
}
// Insert JavaScript function to open link
string jsText = "function OpenLink(uri) { app.launchURL(uri, true); }";
PdfAction js = PdfAction.JavaScript(jsText, myWriter);
myWriter.AddJavaScript(js);
myDocument.Close();
}
}
return new MemoryStream(myMemoryStream.GetBuffer());
}
I got most code from this answer: https://stackoverflow.com/a/8141831/596758
According to Aaron Digulla's answer, you can't actually do this without modifying the PDF reader. Sorry!
I think you can't do this without changing Acrobat Reader... I suggest ... some other PDF reader which doesn't use a "single document" UI. [Foxit Reader] uses tabs and can display several PDF documents.
Could this be of interest: JS to open pdf's in new window? I'm assuming that you can at least add JavaScript to the page. You shouldn't have to modify the PDF's themselves in order to open them in a new window, and even though you might not be able to modify the url's themselves you should be free to open those links in any fashion you want on your page. Or am I completely misunderstanding your question? :)

How do you get an iframe to load content from a link on another page?

Here's the scenario:
I have a link on "page1.html" that i want to get displayed on an iframe of another link "page2.html" .
How do I do this?
Fourth and final try!
The problem with your page is the following
Your problem is that your link [See adoptable dogs] points to http://hssv.convio.net/PageServer?pagename=adoption_available?http://adopt.hssv.org/search/searchResults.asp?task=search&searchid=&advanced=&s=adoption&animalType=3%2C16&statusID=3&submitbtn=Find+Animals
When I go to
http://hssv.convio.net/PageServer?pagename=adoption_available,
I'm redirected to
http://hssv.convio.net/site/PageServer?pagename=page_not_found
Therefore I assume the correct link is http://hssv.convio.net/site/PageServer?pagename=adoption_available (yup, that loaded a page correctly, you were missing /site/ within the link)
Now the second part of your problem. Your page that contains an iframe expected the name of the page to load into the iframe to be everything after the '?', which was fine before since you were't using any other params in the URL (actually not fine, since it breaks easily)
so your link should be (note that the url passed as a parameter should be url encoded)
http://hssv.convio.net/site/PageServer?pagename=adoption_available&content=http%3A%2F%2Fadopt.hssv.org%2Fsearch%2FsearchResults.asp%3Ftask%3Dsearch%26searchid%3D%26advanced%3D%26s%3Dadoption%26animalType%3D3%2C16%26statusID%3D3%26submitbtn%3DFind%2BAnimals
And your page containing the iframe should modify LoadContent to the following.
function LoadContent() {
var url = getParams()['content'];
if (url) {
LoadIFrame(url);
}
}
function getParams() {
var paramMap = {};
if (location.search.length == 0) {
return paramMap;
}
var parts = location.search.substring(1).split("&");
for (var i = 0; i < parts.length; i ++) {
var component = parts[i].split("=");
paramMap [decodeURIComponent(component[0])] = decodeURIComponent(component[1]);
}
return paramMap;
}
Lastly, I don't want to sound rude, but it seems like you need to do some studying before you are assigned to modify these pages. These are all very basic concepts of HTML, HTTP, and JS. Some debugging would easily identify your problem and it had nothing to do with what you asked initially, it was simply that you modified code without a clue to what it was doing...
