can a function be recognized inside a function when both would be exported?
this is my code
exports.generateUrlWithParam = function(idpUrl,subUrl,param){
var url = generateUrl(idpUrl, subUrl);
if(url == null) {
return null;
}
var paramStr = generateParam(param);
return url + "?" + paramStr;
}
and this function is to be used inside generateUrlWithParam
exports.generateUrl = function(idpUrl, subUrl) {
if((idpUrl == null || ""==idpUrl.trim()) && (subUrl == null || ""==subUrl.trim())) {
return null;
}
let url = idpUrl
if(!idpUrl.endsWith("/")) {
url += "/";
}
url += subUrl;
url = url.replace(/\/+/g, "/");
if(url.startsWith("http:/") && !url.startsWith("http://")) {
url = url.replace(/^http:\//, "http://");
} else if(url.startsWith("https:/") && !url.startsWith("https://")) {
url = url.replace(/^https:\//, "https://");
}
return url;
}
and they will be used in ejs file.
apparently generateUrl is not recognized
i'm using this js file by 'require' in my router file and hand to the ejs file
any ideas would be appreciated in advance thank you.
You can refer this function as var url = exports.generateUrl(idpUrl, subUrl);

In Add Link page, is it possible to change the default values like title, address, show these links to, by using URL parameters?
According to this, it seems possible in sharepoint2010. Does anyone know whether it works in 2013??
If not, is it possible to add a link by post REST API??
This problem can be solved by the steps below.
Add a custom action. Just follow the steps here.
In my case code is as below
SP.SOD.executeFunc("callout.js", "Callout", function() {
var itemCtx = {};
itemCtx.Templates = {};
itemCtx.BaseViewID = 'Callout';
// Define the list template type
itemCtx.ListTemplateType = 101;
itemCtx.Templates.Footer = function(itemCtx) {
// context, custom action function, show the ECB menu (boolean)
return CalloutRenderFooterTemplate(itemCtx, AddCustomAction, true);
};
SPClientTemplates.TemplateManager.RegisterTemplateOverrides(itemCtx);
});
function AddCustomAction(renderCtx, calloutActionMenu) {
// Add your custom action
calloutActionMenu.addAction(new CalloutAction({
text: "FAVORITE",
// tooltip: 'This is your custom action',
onClickCallback: function() {
CreateCustomNewQuickLink(renderCtx.CurrentItem.FileLeafRef, renderCtx.CurrentItem.FileRef);
}
}));
// Show the default document library actions
CalloutOnPostRenderTemplate(renderCtx, calloutActionMenu);
}
function CreateCustomNewQuickLink(title, url) {
var urlAddress = $(location).attr('protocol') + "//" + $(location).attr('host') + '/_Layouts/quicklinksdialogformTEST.aspx?Mode=Link' +
'&title=' + encodeURIComponent(title) +
'&url=' + encodeURIComponent(url);
ShowNewQuicklinkPopup(urlAddress, PageRefreshOnDialogClose);
}
Create a new add link page which is copied from "quicklinksdialogform.aspx". I add some javascript as below.
$(init)
function init() {
var args = new Object();
args = GetUrlParms();
if (args["title"] != undefined) {
$(".ms-long")[0].value = decodeURIComponent(args["title"]);
}
if (args["url"] != undefined) {
$(".ms-long")[1].value = decodeURIComponent(args["url"]);
}
}
function GetUrlParms() {
var args = new Object();
var query = location.search.substring(1);
var pairs = query.split("&");
for (var i = 0; i < pairs.length; i++) {
var pos = pairs[i].indexOf('=');
if (pos == -1) continue;
var argname = pairs[i].substring(0, pos);
var value = pairs[i].substring(pos + 1);
args[argname] = unescape(value);
}
return args;
}
It works like below
I am working currently on a project that requires to send custom GET HTTP requests.
I am using the default querystring builder : the Documentation
const querystring = require('querystring');
The problem is for Object (probably also for empty array) such as
extendTypes={}
is serialiazed as :
extendTypes=
The expected result :
extendTypes={}
or its URI encoded version :
extendTypes%3D%7B%7D
So , how can I ever hope to do that ? If It is impossible with the in-builded module, which one could do what I want.
Here is my full code if you want :
function generateGetRequest(dataMap, url) {
let queryParams = {};
let uriParams = {};
for (let [key, value] of dataMap) {
// if value is an object or an array
if (value instanceof Object || value instanceof Array) {
uriParams[key] = value;
} else {
// param working for superagent
queryParams[key] = value;
}
}
let queryParamsUri = querystring.stringify(uriParams);
console.log(queryParamsUri);
let finalUrl = url + ( (Object.keys(uriParams).length > 0) ? "?" + queryParamsUri : "");
}
I finally found a workaround , if someone wants to know :
let request = require("superagent");
function generateGetRequest(dataMap, url) {
let queryParams = {};
let queryParamsUri = "";
let isFirstParam = true;
for (let [key, value] of dataMap) {
// if value is an object or an array
if (value instanceof Object) {
// Workaround for empty object or array = https://github.com/nodejs/node/issues/12234
queryParamsUri += ((!isFirstParam) ? "&": "") + key + "=" + JSON.stringify(value);
// for next call
isFirstParam = false;
} else {
// param working for superagent
queryParams[key] = value;
}
}
let finalUrl = url + ( (!isFirstParam) ? "?" + queryParamsUri : "");
return request
.get(finalUrl)
.query(queryParams);
}

I'm trying to create a simple chrome extension using the following google RSS reader sample,
http://code.google.com/chrome/extensions/samples.html#597015d3bcce3da693b02314afd607bec4f55291
I can add links in the pop-up window that open tabs, but not from the feeds themselves.
Looping through the items in the feed, grabbing title tags and link tags, I want the title to link the the appropriate sites
var entries = doc.getElementsByTagName('item');
var count = Math.min(entries.length, maxFeedItems);
for (var i = 0; i < count; i++) {
item = entries.item(i);
// Grab the title for the feed item.
var itemTitle = item.getElementsByTagName('title')[0];
if (itemTitle) {
itemTitle = itemTitle.textContent;
} else {
itemTitle = "Unknown title";
}
// Grab the link for this feed item
var itemLink = item.getElementsByTagName('link')[0];
if (itemLink) {
itemLink = itemLink.textContent;
} else {
itemLink = "Unknown link";
}
var title = document.createElement("a");
title.className = "item_title";
title.innerText = itemTitle; //display title in iframe
title.addEventListener("click", titleLink); // should open link when clicking on title, but does not.
}
// -------------------------------------------------------------------
// Show |url| in a new tab.
function showUrl(url) {
// Only allow http and https URLs.
if (url.indexOf("http:") != 0 && url.indexOf("https:") != 0) {
return;
}
chrome.tabs.create({url: url});
}
function moreStories(event) {
showUrl(moreStoriesUrl);
}
function titleLink(event) {
showUrl(itemLink);
}
Any thoughts on why this is not working.
If I replace title.addEventListener("click", titleLink); with title.addEventListener("click", moreStories); each title will link to moreStories, I cannot get each title to link to itemLink.
Thanks
Its a bit hard to answer your question without the whole code, but Ill give it a shot ;)
First up, titleLink() isnt going to work because itemLink isnt known. When you create title (the link) you should of attached it to that...say title.href=itemLink then in tiltleLinks you could access that href with showUrl(event.currentTarget.href)
Also did you fix the error in that example?...if not then change frameLoaded to....
function frameLoaded() {
var links = document.getElementsByTagName("A");
for (i = 0; i < links.length; i++) {
var clssName = links[i].className;
if (clssName != "item_title" && clssName != "open_box") {
links[i].addEventListener("click", showStory);
}
}
window.addEventListener("message", messageHandler);
}
If you still have probs could you attach the whole code so I can see what your doing and Ill give you a hand.
Thank you very much for your help.
code title.href=itemLink and code showUrl(event.currentTarget.href) was exactly what I needed.
For completeness, here is the full code,
<script id="iframe_script">
function reportHeight() {
var msg = JSON.stringify({type:"size", size:document.body.offsetHeight});
parent.postMessage(msg, "*");
}
function frameLoaded() {
var links = document.getElementsByTagName("A");
for (i = 0; i < links.length; i++) {
var class = links[i].className;
if (class != "item_title" && class != "open_box") {
links[i].addEventListener("click", showStory);
}
}
window.addEventListener("message", messageHandler);
}
function showStory(event) {
var href = event.currentTarget.href;
parent.postMessage(JSON.stringify({type:"show", url:href}), "*");
event.preventDefault();
}
function messageHandler(event) {
reportHeight();
