How to modify anchor tags in botframework Web chat

We've just started using the bot-framework. For client side we are using the cdn and not react. We have certain links that bot responds with. And we would like to append a url parameter to each link and open the link in the same window. So far this is what my code looks like. Is there a better way to achieve this using the botframework. I know there is cardActionMiddleware which has openUrl cardAction, but we don't have any cards and I am not sure on how to implement that.
var webchatMount = document.getElementById('webchatMount');
function loadChatbot() {
var xhr = new XMLHttpRequest();
xhr.open('GET', "https://webchat.botframework.com/api/tokens", true);
xhr.setRequestHeader('Authorization', 'BotConnector ' + '<secret>');
xhr.send();
xhr.onreadystatechange = function (e) {
if (xhr.readyState == 4 && xhr.status == 200) {
var response = JSON.parse(xhr.responseText);
var store = window.WebChat.createStore({}, function ({ dispatch }) {
return function (next) {
return function (action) {
if (action.type === 'DIRECT_LINE/INCOMING_ACTIVITY') {
var event = new Event('webchatincomingactivity');
event.data = action.payload.activity;
window.dispatchEvent(event);
}
return next(action);
}
}
});
window.WebChat.renderWebChat(
{
directLine: window.WebChat.createDirectLine({ token: response }),
store: store,
},
webchatMount
);
document.querySelector('.webchat__send-box-text-box__input').focus();
window.addEventListener('webchatincomingactivity', ({ data }) => {
setTimeout(function () {
var links = document.querySelectorAll('#webchatMount a');
if (links.length >= 1) {
for (var i = 0; i <= links.length; i++) {
if (links[i] == undefined)
break;
var compare = new RegExp('maindomain');
var href = links[i].getAttribute('href');
var st = getParameterByName('st', href);
if (links[i].hasAttribute('target')) {
links[i].removeAttribute('target');
}
if (compare.test(href)) {
// internal link
// check if it has st=INTRA
if (st) {
console.log(' it has a value');
} else {
links[i].setAttribute('href', insertParam('st', 'INTRA', href));
}
} else {
// external link, do nothing
}
}
}
}, 1000);
});
}
}
}
and here are getParameterByName and insertParam functions.
function getParameterByName(name, url) {
name = name.replace(/[\[\]]/g, '\\$&');
var regex = new RegExp('[?&]' + name + '(=([^&#]*)|&|#|$)'),
results = regex.exec(url);
if (!results) return null;
if (!results[2]) return '';
return decodeURIComponent(results[2].replace(/\+/g, ' '));
}
function insertParam(key, value, url) {
key = encodeURIComponent(key);
value = encodeURIComponent(value);
// kvp looks like ['key1=value1', 'key2=value2', ...]
var kvp = url.split('&');
var i=0;
for(; i<kvp.length; i++){
if (kvp[i].startsWith(key + '=')) {
var pair = kvp[i].split('=');
pair[1] = value;
kvp[i] = pair.join('=');
break;
}
}
if(i >= kvp.length){
kvp[kvp.length] = [key,value].join('=');
}
return kvp.join('&');
}
I am new to botframework webchat so I don't know it very well. I know that the secret should not be used like that, but for know we are testing and would like to get it to work. Any help would be appericiated
Thanks.

html table no longer supported

As others before I used yql to get data from a website. The website is in xml format.
I am doing this to build a web data connector in Tableau to connect to xmldata and I got my code from here: https://github.com/tableau/webdataconnector/blob/v1.1.0/Examples/xmlConnector.html
As recommended on here: YQL: html table is no longer supported I tried htmlstring and added the reference to the community environment.
// try to use yql as a proxy
function _yqlProxyAjaxRequest2(url, successCallback){
var yqlQueryBase = "http://query.yahooapis.com/v1/public/yql?q=";
var query = "select * from htmlstring where url='" + url + "'";
var restOfQueryString = "&format=xml" ;
var yqlUrl = yqlQueryBase + encodeURIComponent(query) + restOfQueryString + "&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
_ajaxRequestHelper(url, successCallback, yqlUrl, _giveUpOnUrl9);
}
function _giveUpOnUrl9(url, successCallback) {
tableau.abortWithError("Could not load url: " + url);
}
However, I still got the message: Html table no longer supported.
As I don't know much about yql, I tried to work with xmlHttpRequestinstead, but Tableau ended up processing the request for ages and nothing happened.
Here my attempt to find another solution and avoid the yql thingy:
function _retrieveXmlData(retrieveDataCallback) {
if (!window.cachedTableData) {
var conData = JSON.parse(tableau.connectionData);
var xmlString = conData.xmlString;
if (conData.xmlUrl) {
var successCallback = function(data) {
window.cachedTableData = _xmlToTable(data);
retrieveDataCallback(window.cachedTableData);
};
//INSTEAD OF THIS:
//_basicAjaxRequest1(conData.xmlUrl, successCallback);
//USE NOT YQL BUT XMLHTTPREQUEST:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
myFunction(this);
}
};
xhttp.open('GET', 'https://www.w3schools.com/xml/cd_catalog.xml', true);
xhttp.send();
return;
}
try {
var xmlDoc = $.parseXML(conData.xmlString);
window.cachedTableData = _xmlToTable(xmlDoc);
}
catch (e) {
tableau.abortWithError("unable to parse xml data");
return;
}
}
retrieveDataCallback(window.cachedTableData);
}
Does anyone have an idea how to get YQL work or comment on my approach trying to avoid it?
Thank you very much!

Calling Server Side Scripting from JavaScript Not Working in Asp.Net

I want to call Server Side function using JavaScript . I m using PageMethod.
But Code is not working. Please tell Error in code Block.
I m using two JavaScript function onLoad. AJAX Script Manager PageMethod is also set to true.
My Server Side Function in not taking any value as input nor returning any value.
function GetData() {
PageMethods.GetData(OnSuccess);
}
function OnSuccess(response, userContext, methodName) {
alert(response);
}
function GetOS() {
console.log("rom");
$('input[type="checkbox"]').on('change', function (e) {

Check if a field value exists in another SharePoint list before creating an item

I want to check if an item value exists in another list before saving it using PreSaveAction function. The value I want to check is EventDate
function PreSaveAction() {
var time = SPUtility.GetSPFieldByInternalName('EventDate').GetValue();
alert(time);
//Validation for current fields
if(SPUtility.GetSPField('Field').GetValue() == "yes")
{
alert('Validation passed, let SharePoint continue');
return true;}
else
{
alert('Validation failed, let SharePoint not continue');
return false;
}
}
And I get the items from the second list with this:
function ViewItem()
{
var context = new SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('demoTrainingRoom2');
var query = SP.CamlQuery.createAllItemsQuery();
allItems = list.getItems(query);
context.load(allItems, 'Include(Title, EventDate)');
context.executeQueryAsync(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed));
}
function success() {
//var contador = this.allitems.getCount();
var TextFiled = "";
var ListEnumerator = this.allItems.getEnumerator();
var firstListTime = SPUtility.GetSPFieldByInternalName('EventDate').GetValue();
while(ListEnumerator.moveNext())
{
var currentItem = ListEnumerator.get_current();
TextFiled += currentItem.get_item('Title') + '-' + currentItem.get_item('EventDate'); +'\n';
}
alert(TextFiled);
}
function failed(sender, args) {
alert("failed. Message:" + args.get_message());
}
So basically I want to check if any item on list 1 has the same EventDate on list 2 when using PreSaveAction. Any help will be kindly appreciated
UPDATE
Thank you for the interest, now i can succesfully check if a value on the first list exist in the second list with the following code. Now I need to pass the output of that check to the PreSaveAction function when demoField is equal to yes
function ViewItem()
{
var context = new SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('demoTrainingRoom2');
var query = SP.CamlQuery.createAllItemsQuery();
allItems = list.getItems(query);
context.load(allItems, 'Include(Title, EventDate)');
context.executeQueryAsync(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed));
}
function success() {
var currentTitle = SPUtility.GetSPFieldByInternalName('EventDate').GetValue();
for(var i = 0; i < this.allItems.get_count(); i++){
var item = this.allItems.get_item(i);
console.log(item.get_item('EventDate'));
if (currentTitle === item.get_item('EventDate')){
alert('I exist on the second list' + ' ' + item.get_item('EventDate'));
return true; // or item
}
}
return false;
}
function failed(sender, args) {
alert("failed. Message:" + args.get_message());
}
function PreSaveAction() {
var time = SPUtility.GetSPFieldByInternalName('EventDate').GetValue();
if(SPUtility.GetSPField('demoField').GetValue() == "yes")
{
//Saving File
return true;}
else
{
//NOt saving FIle
return false;
}
}
Thank you in advance for the assistance

call the PreSaveAction() method inside the your first list OnSuccess() method , pass event date as a caml query to the second list i.e query 2nd list on event date ......... this is just snippet may contain some error , check out
function ViewItem()
{
var context = new SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('demoTrainingRoom2');
var query = SP.CamlQuery.createAllItemsQuery();
allItems = list.getItems(query);
context.load(allItems, 'Include(Title, EventDate)');
context.executeQueryAsync(Function.createDelegate(this, this.success),Function.createDelegate(this, this.failed));
}
function success() {
var TextFiled = "";
var ListEnumerator = this.allItems.getEnumerator();
var firstListTime = SPUtility.GetSPFieldByInternalName('EventDate').GetValue();
while(ListEnumerator.moveNext())
{
var evtDate = currentItem.get_item('EventDate');
function PreSaveAction() {
var clientContext = new SP.ClientContext(siteUrl);
var oList = clientContext.get_web().get_lists().getByTitle('List2');
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml('<View><Query><Where><Eq><FieldRef Name=\'EventDate\'/>' +
'<Value Type=\'DateTime\'>'+ evtDate +'</Value></Eq></Where></Query><RowLimit>1</RowLimit></View>');
this.collListItem = oList.getItems(camlQuery);
clientContext.load(collListItem);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
}
}
function onQuerySucceeded(sender, args) {
var listItemInfo = '';
var listItemEnumerator = collListItem.getEnumerator();
while (listItemEnumerator.moveNext()) {
alert('event date exist')
}
}
function onQueryFailed(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

Something is preventing my submit button from functioning

I posted earlier regarding a different topic and want to thank all who helped me out. I've cleaned up my code pretty well (I think) but now when I click 'submit' nothing happens. I suspect the issue is regarding sending data with ajax but there is a problem with the way I've written things to send both text and radio data. Before posting this, I did do a thorough search to see if the question may have been answered in another's post but didn't find it - probably because I'm not astute enough with javascript to relate it to my own code. Anyway, here is a sample http://jsfiddle.net/J2yWQ/78/ If someone could find my issue I would really appreciate it.
