javascript .send() not working on mobile - javascript

this javascript is working on desktop but not on mobile browsers. Is there an edit which could resolve this?
The script send the results to a questionnaire to a google document to pull out the results. It works ok on a desktop browser but no luck on mobiles.
<script>
var myForm = document.getElementById("questionnaire");
if (myForm) {
myForm.onsubmit = function(evt) {
evt.preventDefault();
var questionDiv = document.getElementById('question-div');
var busyDiv = document.getElementById('busy');
var resultDiv = document.getElementById('result-div');
var resultList = document.getElementById('result-list');
var xhr = new XMLHttpRequest();
var url = "https://script.google.com/macros/s/AKfycbzGx6a6eogfVTaKD_3a4kiLBZfcdD5GMoonNsSSY1-sCCJfPDI/exec";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.onload = function() {
if(xhr.readyState == 4 && xhr.status == 200) {
var response = JSON.parse(xhr.responseText);
var result = response.result;
for (var i in result) {
var e = result[i];
if (e) {
var li = document.createElement('li');
if (e.url) {
var a = document.createElement('a');
a.href = e.url;
a.textContent = e.name;
li.appendChild(a);
} else {
li.textContent = e.name;
}
resultList.appendChild(li);
}
}
busyDiv.hidden = true;
resultDiv.hidden = false;
}
}
var form = document.getElementById('questionnaire');
var formData = new FormData(form);
var fields = ['name','email','yob','gender','income','asset','q1','q2','q3','q4','q5','q6','q7','q8','q9','q10'];
var params = [];
for (var i in fields) {
var field = fields[i];
params.push(field + "=" + formData.get(field));
}
xhr.send(params.join('&'));
questionDiv.hidden=true;

JS script won't run/execute (no errors)

I have this script that should execute at window.onload, populating the html elements from a parsed JSON through XMLHttpRequest. The console log doesn't throw any errors but the script does nothing.
Also I'm running this on a virtual server if it makes any difference.
var filename = document.getElementById('filename').innerHTML

var xml = new XMLHttpRequest();

Any suggestions?

How to parse a csv file using sapui5 FileUploader controller

I want to get a file from client side to parse it into json object and send it to the backend, i am able to parse the file thanks to Sheet-js.
My problem is i can not get files from client side
I am using js, SAPUI5
handleUploadPress: function(oEvent) {
var oFileUploader = this.getView().byId("fileUploader");
if (!oFileUploader.getValue().toString()) {
MessageToast.show("Choose a xlsx file first");
return;
}
var url = "/resources/test.xlsx";
var oReq = new XMLHttpRequest();
oReq.open("GET", url, true);
oReq.responseType = "arraybuffer";
oReq.onload = function(e) {
var arraybuffer = oReq.response;
var data = new Uint8Array(arraybuffer);
var arr = [];
for (var i = 0; i !== data.length; ++i) {
arr[i] = String.fromCharCode(data[i]);
}
var bstr = arr.join("");
var workbook = XLSX.read(bstr, {
type: "binary"
});
var firstSheetName = workbook.SheetNames[0];
var worksheet = workbook.Sheets[firstSheetName];
var json = XLSX.utils.sheet_to_json(worksheet, {
raw: true
});
var jsonStr = JSON.stringify(json);
MessageBox.show("JSON String: " + jsonStr);
};
oReq.send();
},
The answer is:

jQuery AppendChild With Images

I am trying to append an image into a span, it works perfectly outputting the image path as text using:
homeTeamName_span.appendChild(homeTeamName_crest);
However, when trying to wrap image tags around it, it doesn't do anything and no data will load because of it.
What would be the reason for this?
homeTeamName_span.appendChild("<img src='homeTeamName_crest' />");
Function source
window.onload = function() {
var xmlhttp = new XMLHttpRequest();
var url = "http://bushell.net/football/site/includes/webservice.php?service=allfixtures&limit=10&competition=427";
var url2 = "http://bushell.net/football/site/includes/webservice.php?service=allfixtures&limit=10&competition=426"
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
getECL(xmlhttp.responseText);
}
}
xmlhttp.open("GET", url, true);
xmlhttp.send();
function getECL(response) {
var ECL_arr = JSON.parse(response);
var i;
//add 6hrs
var ecl_games = document.getElementById("ecl-games");
for(i = 0; i < ECL_arr.length; i++) {
var gameInfo_container = document.createElement("LI");
ecl_games.appendChild(gameInfo_container);
var homeTeamName_span = document.createElement("SPAN");
homeTeamName_span.className = "text-right";
var homeTeamName_text = document.createTextNode(ECL_arr[i].homeTeamName);
homeTeamName_span.appendChild(homeTeamName_text);
gameInfo_container.appendChild(homeTeamName_span);
var date_span = document.createElement("SPAN");
date_span.className = "d-g";
var date_span_text = document.createTextNode(ECL_arr[i].date);
date_span.appendChild(date_span_text);
gameInfo_container.appendChild(date_span);
var awayTeamName_span = document.createElement("SPAN");
awayTeamName_span.className = "text-left";
var awayTeamName_text = document.createTextNode(ECL_arr[i].awayTeamName);
awayTeamName_span.appendChild(awayTeamName_text);
gameInfo_container.appendChild(awayTeamName_span);
}
xmlhttp.onreadystatechange=function() {
if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
getPrem(xmlhttp.responseText);
}
}
xmlhttp.open("GET", url2, true);
xmlhttp.send();
function getPrem(response){
var prem_arr = JSON.parse(response);
var prem_games = document.getElementById("prem-games");
for(var j = 0; j<prem_arr.length; j++) {
var gameInfo_container = document.createElement("LI");
prem_games.appendChild(gameInfo_container);
var homeTeamName_span = document.createElement("SPAN");
homeTeamName_span.className = "text-right";
var homeTeamName_text = document.createTextNode(prem_arr[j].homeTeamName);
var homeTeamName_crest = document.createTextNode(prem_arr[j].homeTeamCrest);
homeTeamName_span.appendChild("<img src='homeTeamName_crest' />");
homeTeamName_span.appendChild(homeTeamName_text);
gameInfo_container.appendChild(homeTeamName_span);
var date_span = document.createElement("SPAN");
date_span.className = "d-g";
var date_span_text = document.createTextNode(prem_arr[j].date);
date_span.appendChild(date_span_text);
gameInfo_container.appendChild(date_span);
var awayTeamName_span = document.createElement("SPAN");
awayTeamName_span.className = "text-left";
var awayTeamName_text = document.createTextNode(prem_arr[j].awayTeamName);
awayTeamName_span.appendChild(awayTeamName_text);
gameInfo_container.appendChild(awayTeamName_span);
}
console.log("loop finished");
}
}
this shoud work , if homeTeamName_crest is the path of the picture
$(homeTeamName_span).append("<img src='"+homeTeamName_crest+"' />")
What if you do this?
var homeTeamName_crest = prem_arr[j].homeTeamCrest; // <--- change this line, don't make it a textNode
homeTeamName_span.appendChild("<img src='" + homeTeamName_crest + '/>"); // <--- change this line, we want to interpolate the string as the path to the image

JS search returned xhr.responseText for div then remove div

I would like to search a xhr.responseText for a div with an id like "something" and then remove all the content from the xhr.responseText contained within that div.
Here is my xhr code:
function getSource(source) {
var url = source[0];
var date = source[1];
/****DEALS WITH CORS****/
var cors_api_host = 'cors-anywhere.herokuapp.com';
var cors_api_url = 'https://' + cors_api_host + '/';
var slice = [].slice;
var origin = self.location.protocol + '//' + self.location.host;
var open = XMLHttpRequest.prototype.open;
XMLHttpRequest.prototype.open = function () {
var args = slice.call(arguments);
var targetOrigin = /^https?:\/\/([^\/]+)/i.exec(args[1]);
if (targetOrigin && targetOrigin[0].toLowerCase() !== origin &&
targetOrigin[1] !== cors_api_host) {
args[1] = cors_api_url + args[1];
}
return open.apply(this, args);
};
/****END DEALS WITH CORS****/
var xhr = new XMLHttpRequest();
xhr.open("GET", cors_api_url+url, true);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
var resp = xhr.responseText;
var respWithoutDiv = removeErroneousData(resp);
}
else{
return "Failed to remove data.";
}
}
xhr.send();
}
remove div here:
/*This must be in JS not JQUERY, its in a web worker*/
function removeErroneousData(resp) {
var removedDivResp = "";
/*pseudo code for removing div*/
if (resp.contains(div with id disclosures){
removedDivResp = resp.removeData(div, 'disclosures');
}
return removedDivResp;
}
You can dump the response in a div and then search for that div you want empty its content.
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
var resp = xhr.responseText;
$('div').attr('id', 'resp').html(resp);
$('#resp').find('disclosures').html('');
//var respWithoutDiv = removeErroneousData(resp);
}
else{
return "Failed to remove data.";
}
}

how to use json object as id attribute of li elements or anchor tag id using javascript

function showNews(news) {
var i, ntitle, ncontent, ndate, nid;

var cont = document.getElementById("cont");
var div1 = document.getElementById("div1");
var panelHead = document.getElementById("Heading");
var NewsHead = document.getElementById("NewsHead");
var head = document.getElementById("head");
div1.setAttribute("class", " col-md-3 panel panel-primary");
panelHead.setAttribute("class", "panel-heading");

var div2 = document.getElementById("div2");
div2.style.marginTop = "10px";
div2.setAttribute("class", " col-md-9 col-md-offset-0 panel panel-primary");
var panelHead = document.getElementById("NewsDesc");
var Title = document.getElementById("Title");
panelHead.setAttribute("class", "panel panel-heading");
Title.appendChild(document.createTextNode("News"));
panelHead.appendChild(Title);
var ul = document.createElement("ul");
var li = document.createElement("li");
var a = document.createElement("a");
**a.setAttribute("id",ntitle);** /// here i want to use
ntitle object as id
attribute of li
a.setAttribute("href", "#");
a.appendChild(document.createTextNode(ntitle));
li.appendChild(a);
ul.appendChild(li);
div1.appendChild(ul);
cont.appendChild(div1);
cont.appendChild(div2);
$(document).ready(function () {
$("li").click(function () {
$("#cur[i].title").click(function () {
$("#h1").text(ntitle);
$("#p1").text(ncontent);
//p1.setAttribute("class", "jumbotron");
});
});
});
cont.appendChild(document.createElement("hr"));
}
}
</script>
In your for loop couldn't you just construct the li elements as strings and use jQuery's insert function?
