javascript method chaining not working - javascript

Have a literal object with methods.
I want to chain the methods to each other using appendChild DOM method.
In the createStructure method if i separate the assignmentsd from each other, works.
var row = this.createRow();
row.appendChild(this.createHeadCells());
this.DBTable.appendChild(row);
If i chain the methods to each other it wont, no error message.
this.DBTable.appendChild(this.createRow().appendChild(this.createHeadCells()));
Otherwise this chaining is working:
document.body.appendChild(document.createElement('p').appendChild(document.createElement('span').appendChild(document.createTextNode('abc')));
What did i wrong?
The Code:
var readyStateCheckInterval = setInterval(function () {
if (document.readyState === "complete" || document.readyState === "loaded") {
clearInterval(readyStateCheckInterval);
init();
}
}, 10);
var DBTable =
{
DBTable : document.createDocumentFragment(),
colNum : 0,
rowNum : 0,
createTable : function(colNum, rowNum)
{
this.DBTable = document.createElement('table');
this.colNum = colNum;
this.rowNum = rowNum;
this.createTableStructure();
},
createRow : function()
{
return document.createElement('tr');
},
createHeadCells : function()
{
var df = document.createDocumentFragment();
for ( var a = 0; a < this.colNum; a++)
{
df.appendChild(document.createElement('th'));
}
return df;
},
createDataCells : function()
{
var df = document.createDocumentFragment();
for ( var a = 0; a < this.colNum; a++)
{
df.appendChild(document.createElement('td'));
}
return df;
},
createTableStructure : function()
{
var row = this.createRow();
row.appendChild(this.createHeadCells());
this.DBTable.appendChild(row);
this.DBTable.appendChild(this.createRow().appendChild(this.createHeadCells()));
/*
for ( var a = 0; a < this.rowNum; a++) {
var row = this.createRow();
row.appendChild(this.createDataCells());
this.DBTable.appendChild(row);
//this.DBTable.appendChild(this.createRow().appendChild(this.createDataCells()));
}
*/
document.body.appendChild(this.DBTable);
}
};
function init() {
DBTable.createTable(3,4);
var td = document.querySelectorAll('td');
for (var el in td) {
td[el].innerHTML = 'asdf';
}
var th = document.querySelectorAll('th');
for (var el2 in th) {
th[el2].innerHTML = 'abcd';
}
}

TinyMce 5 setcontent unable to set html properly

I am writing a tinymce custom plugin called Mergetable. which will merger two user selected table.
Problem statement:
TinyMce is not allowing to select two table , by using shift and mouse I can select content of the table. So I can't use tinmce.activeeditor.selection.getNode() method instead using tinmce.activeeditor.selection.getContent().
Form getcontent() method I am getting proper html of both table. After do some operation while setting content using tinmce.activeeditor.selection.setContent() both table merged properly but two more table with empty td created one in top and one in bottom . Please see below plugin code.
code:
(function () {
var mergeTable = (function () {
'use strict';
tinymce.PluginManager.add("mergeTable", function (editor, url) {
function Merge(){
var selectedhtml=editor.selection.getContent();
//using getContent() as getnode returning body node
var dv=document.createElement('div');
dv.innerHTML= selectedhtml;
var tableElements = dv.getElementsByTagName('TABLE');
if (tableElements.length == 2) {
var tableOne = tableElements[0];
var tableTwo = tableElements[1];
var tempTable = null;
var offsetLeft = tableOne.offsetLeft;
var offsetTop = tableOne.offsetTop;
var elem = tableElements[0];
if (tableOne.nodeName == "TABLE" && tableTwo.nodeName == "TABLE") {
for (var r = 0; r < tableTwo.rows.length; r++) {
var newTR = tableOne.insertRow(tableOne.rows.length);
for (var i = 0; i < tableTwo.rows[r].cells.length; i++) {
var newTD = newTR.insertCell()
newTD.innerHTML = tableTwo.rows[r].cells[i].innerHTML;
newTD.colSpan = tableTwo.rows[r].cells[i].colSpan;
newTD.rowSpan = tableTwo.rows[r].cells[i].rowSpan;
newTD.style.cssText = tableTwo.rows[r].cells[i].style.cssText;
if (tableOne.style.border != "") {
newTD.style.border = "1px dotted #BFBFBF"
}
}
}
tableTwo.remove();
console.log(dv.innerHTML);
editor.selection.setContent(dv.innerHTML);
editor.nodeChanged();
}
else {
alert("Please select two tables");
}
}
}
editor.ui.registry.addButton('mergeTable', {
text: "Merge Table",
onAction: function(){ Merge();}
});
});
}());
}());
I am able to fix my problem by using some work around . Instead use setContent() method. I have remove selected content and use insertContent().
Please find working code below.
(function () {
var mergeTable = (function () {
'use strict';
tinymce.PluginManager.add("mergeTable", function (editor, url) {
var cmd = function (command) {
return function () {
return editor.execCommand(command);
};
};

var selectedhtml=editor.selection.getContent();
var dv=document.createElement('div');
dv.innerHTML= selectedhtml;
var tableElements = dv.getElementsByTagName('TABLE');
if (tableElements.length == 2) {
var tableOne = tableElements[0];
var tableTwo = tableElements[1];
var tempTable = null;
var tableOneMaxCell=0
var tabletwoMaxCell=0
var tempCellcount=0
var tableOneRowcount=tableOne.rows.length;
tableOne.querySelectorAll("tr").forEach(function(e){
tempCellcount= e.querySelectorAll("td").length ;
if(tempCellcount>tableOneMaxCell)
{
tableOneMaxCell=tempCellcount;
}
});
tableTwo.querySelectorAll("tr").forEach(function(e){
tempCellcount= e.querySelectorAll("td").length ;
if(tempCellcount>tabletwoMaxCell)
{
tabletwoMaxCell=tempCellcount;
}
});
if (tableOne.nodeName == "TABLE" && tableTwo.nodeName == "TABLE") {
for (var r = 0; r < tableTwo.rows.length; r++) {
var newTR = tableOne.insertRow(tableOne.rows.length);
for (var i = 0; i < tableTwo.rows[r].cells.length; i++) {
var newTD = newTR.insertCell()
newTD.innerHTML = tableTwo.rows[r].cells[i].innerHTML;
newTD.colSpan = tableTwo.rows[r].cells[i].colSpan;
newTD.rowSpan = tableTwo.rows[r].cells[i].rowSpan;
newTD.style.cssText = tableTwo.rows[r].cells[i].style.cssText;
if (tableOne.style.border != "") {
newTD.style.border = "1px dotted #BFBFBF"
}
if(i==tableTwo.rows[r].cells.length-1 && tableOneMaxCell>tabletwoMaxCell){
newTD.colSpan = tableTwo.rows[r].cells[i].colSpan + (tableOneMaxCell-tabletwoMaxCell);
}
}
}
for( var t1=0; t1<tableOneRowcount; t1++ ){
var celllen=tableOne.rows[t1].cells.length;

Show all tabs content vanilla js

How can I change this javascript code, that when I click on "Green" I want the content from all tabs to be displayed? https://codepen.io/wangel13/pen/OXBrRp
'use strict';
function Tabs() {
var bindAll = function() {
var menuElements = document.querySelectorAll('[data-tab]');
for(var i = 0; i < menuElements.length ; i++) {
menuElements[i].addEventListener('click', change, false);
}
}
var clear = function() {
var menuElements = document.querySelectorAll('[data-tab]');
for(var i = 0; i < menuElements.length ; i++) {
menuElements[i].classList.remove('active');
var id = menuElements[i].getAttribute('data-tab');
document.getElementById(id).classList.remove('active');
}
}
var change = function(e) {
clear();
e.target.classList.add('active');
var id = e.currentTarget.getAttribute('data-tab');
document.getElementById(id).classList.add('active');
}
bindAll();
}
var connectTabs = new Tabs();
Take a look at this:
'use strict';
function Tabs() {
var bindAll = function() {
var menuElements = document.querySelectorAll('[data-tab]');
for(var i = 0; i < menuElements.length ; i++) {
menuElements[i].addEventListener('click', change, false);
}
}
var clear = function() {
var menuElements = document.querySelectorAll('[data-tab]');
for(var i = 0; i < menuElements.length ; i++) {
menuElements[i].classList.remove('active');
var id = menuElements[i].getAttribute('data-tab');
document.getElementById(id).classList.remove('active');
}
}
function makeAllActive() {
var tabs = document.querySelectorAll('.b-tab');
Array.from(tabs).map(item => {
item.classList.add('active');
});
}
var change = function(e) {
clear();
e.target.classList.add('active');
var id = e.currentTarget.getAttribute('data-tab');
if(id === "green") {
makeAllActive();
return;
}
document.getElementById(id).classList.add('active');
}
bindAll();

want to add AND search to this incremental search plugin

I want to add AND search function to a following incremental search jQuery plugin that can search option elements from select-boxes.
JSFiddle
I'm trying to do these ideas but can't code successfully.
- first of all I want to define white space as a delimiter.
- next I want to distinguish that variable from other white spaces in option elements.
By the way, I don't want to replace a lot of DOM elements.
So, I don't want to use plugin like selectize.js, nether datalist elements anyway.
Somebody help?

Push to an array in a nested loop is repeating the last value

I am trying to push elements to an array in a nested loop, but only the last item is getting repeated in the final array, where am I going wrong, very new to javascript asynchronous concept.Below is the function in which I push the items to an array.
$scope.showBeList = function(feed) {
if (feed[srcServ.KEY_CONTENT_TEXT]) {
var content = JSON.parse(feed[srcServ.KEY_CONTENT_TEXT])
if (content) {
$scope.beList = {};
for (var key in content) {
var decorationVal;
//reading value from a lokijs collection
var decoration = dataServ[srcServ.CONST_COLLECTION_DECORATION].find({
'name': key
});
if (decoration && decoration.length) {
decorationVal = decoration[0];
if (decorationVal != null) {
var tempObj = JSON.parse(decorationVal.value);
if (tempObj) {
var header = tempObj[key][key + '_HEADER'];
if (header) {
var counter = content[key].length;
var tempItems = [];
for (var j = 0; j < content[key].length; j++) {
(function(j) {
var obj = {};
obj[srcServ.KEY_MAIN_HEADER] = tempObj[key][srcServ.KEY_DESC];
obj[srcServ.KEY_SUB_HEADER] = header[srcServ.KEY_DESC];
obj.id = j;
var itemVal = content[key][j][key + '_HEADER'];
var details = [];
var notes = [];
for (var item in itemVal) {
var val = null;
var found = false;
for (var i = 0; i < header.field.length; i++) {
if (header.field[i].name == item) {
val = header.field[i];
found = true;
break;
}
}
if (found && val != null) {
val[srcServ.KEY_DESC_VALUE] = itemVal[item];
details.push(val);
}
}
obj.details = details;
counter--;
if (counter == 0) {
$scope.showMoreDetails = true;
$scope.beList.beItems = tempItems;

JSOM dynamicly get two announcements from all lists in all webs

Need help with the chaining. The functions work. But async calls make it hard for me to get everything. Help me think right!
My thought:
Get All Webs recursively (function works)
Get all lists from webs and iff announcementlist add to array and pass along
Get two items from all announcmentlists and sort by created.
Add ALL announcement items into one large array (to be able to sort array later.
Heres the code,
function getAllWebs(success, error) {
var ctx = SP.ClientContext.get_current();
var web = ctx.get_site().get_rootWeb();
var result = [];
var level = 0;
result.push(web);
var getAllWebsInner = function (web, result, success, error) {
level++;
var ctx = web.get_context();
var webs = web.get_webs();
ctx.load(webs, 'Include(Title,Webs,ServerRelativeUrl)');
ctx.executeQueryAsync(
function () {
for (var i = 0; i < webs.get_count() ; i++) {
var web = webs.getItemAtIndex(i);
result.push(web);
if (web.get_webs().get_count() > 0) {
getAllWebsInner(web, result, success, error);
}
}
level--;
if (level == 0 && success)
success(result);
},
error);
};
getAllWebsInner(web, result, success, error);
}
function error(sender, args) {
console.log(args.get_message());
};
function getAnnouncementLists(web, success, error) {
var dfd = $.Deferred();
var ctx = web.get_context();
var collList = web.get_lists();
var result = []
ctx.load(collList, 'Include(Title, Id, BaseTemplate)');
ctx.executeQueryAsync(function () {
for (var i = 0; i < collList.get_count() ; i++) {
var list = collList.getItemAtIndex(i);
var bTemp = list.get_baseTemplate();
if (bTemp == 104) {
result.push(list);
}
}
//success(result);
dfd.resolve(result);
}, error);
return dfd.promise();
}
function getListItems(list, success, error) {
var dfd = $.Deferred();
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml('<View><Query><OrderBy><FieldRef Name="Created" Ascending="False"></FieldRef>'
+ '</OrderBy></Query><ViewFields><FieldRef Name="Title"/><FieldRef Name="Body"/>' +
'<FieldRef Name="Created"/></ViewFields><RowLimit>2</RowLimit></View>');
var listItems = list.getItems(camlQuery);
var result = []
var ctx = list.get_parentWeb().get_context();
ctx.load(listItems);
ctx.executeQueryAsync(function () {
for (var i = 0; i < listItems.get_count() ; i++) {
var item = listItems.getItemAtIndex(i);
result.push(item);
}
dfd.resolve(result);
//success(result);
}, error);
return dfd.promise();
}
function printResults(items) {
var sortedItems = items.sort(dynamicSort("get_created()"));
alert(sortedItems);
}
function dynamicSort(property) {
var sortOrder = 1;
if (property[0] === "-") {
sortOrder = -1;
property = property.substr(1);
}
return function (a, b) {
var result = (a[property] < b[property]) ? -1 : (a[property] > b[property]) ? 1 : 0;
return result * sortOrder;
}
}
$(document).ready(function () {
var items = getAllWebs(
function (allwebs) {
var array = [];
for (var i = 0; i < allwebs.length; i++) {
getAnnouncementLists(allwebs[i]).then(function (announceLists) {
for (var i = 0; i < announceLists.length; i++) {
getListItems(announceLists[i]).then(function (items) {
array.push(items);
});
}
});
}
return array;
}
);
//getAllWebs(
// function (allwebs) {
// for (var i = 0; i < allwebs.length; i++) {
// getAnnouncementLists(allwebs[i],
// function (announceLists) {
// for (var i = 0; i < announceLists.length; i++) {
// getListItems(announceLists[i],
// function (items) {
// printResults(items);
// }, error);
// }
// }, error);
// }
// }, error);
});
Given the requirements to retrieve list items from Announcements lists located across site collection, below is demonstrated the modified example that contains some improvements such as:
the number of requests to the server is reduced
fixed the issue in getAllWebs function that prevents to return any results if site contains only a root web
Example
function getAllWebs(propertiesToRetrieve,success, error) {
var ctx = SP.ClientContext.get_current();
var web = ctx.get_site().get_rootWeb();
var result = [];
var level = 0;
ctx.load(web, propertiesToRetrieve);
result.push(web);
var getAllWebsInner = function (web, result, success, error) {
level++;
var ctx = web.get_context();
var webs = web.get_webs();
var includeExpr = 'Include(Webs,' + propertiesToRetrieve.join(',') + ')';
ctx.load(webs, includeExpr);
ctx.executeQueryAsync(
function () {
for (var i = 0; i < webs.get_count() ; i++) {
var web = webs.getItemAtIndex(i);
result.push(web);
if (web.get_webs().get_count() > 0) {
getAllWebsInner(web, result, success, error);
}
}
level--;
if (level == 0 && success)
success(result);
},
error);
};
getAllWebsInner(web, result, success, error);
}
function loadListItems(lists,query,success,error,results){
var results = results || [];
var curList = lists[0];
var ctx = curList.get_context();
var listItems = curList.getItems(query);
ctx.load(listItems);
ctx.executeQueryAsync(function () {
results.push.apply(results, listItems.get_data());
lists.shift();
if(lists.length > 0) {
loadListItems(lists,query,success,error,results);
}
if(lists.length == 0)
success(results);
}, error);
}
function dynamicSort(property) {
var sortOrder = 1;
if (property[0] === "-") {
sortOrder = -1;
property = property.substr(1);
}
return function (a, b) {
var result = (a[property] < b[property]) ? -1 : (a[property] > b[property]) ? 1 : 0;
return result * sortOrder;
}
}
var propertiesToRetrieve = ['Lists.Include(BaseTemplate)','ServerRelativeUrl'];
getAllWebs(propertiesToRetrieve,
function(allwebs){
//1. get filtered lists
var allAnnouncementLists = [];
allwebs.forEach(function(w){
var announcementLists = w.get_lists().get_data().filter(function(l){
if(l.get_baseTemplate() == SP.ListTemplateType.announcements)
return l;
});
allAnnouncementLists.push.apply(allAnnouncementLists, announcementLists);
});
//2.Load list items from lists
var query = new SP.CamlQuery(); //<-set your custom query here
loadListItems(allAnnouncementLists,query,
function(allListItems){
//3.Sort and print results
var sortedItems = allListItems.sort(dynamicSort("get_created()"));
sortedItems.forEach(function(item){
console.log(item.get_item('Title'));
});
},logError);
},
logError);
function logError(sender,args){
console.log(args.get_message());
}
