I've tried using the techniques mentioned in these questions, but I haven't had any luck. I'm trying to adjust a JavaScript function to retrieve multiple divs using the getElementById method.
Here is the current line of code within the function which retrieves the div #cat1:
var elem = document.getElementById(cat1);
Moving forward, I need this function to also retrieve the div #cat2.
jQuery can be loaded if there's a better method to accomplish this using their library?
Here is the full function (reference Line 3):
function getCategories(initial) {
var i;
var elem = document.getElementById('cat1');
if (initial == 1) {
jsonGroups = "";
jsonGroups = '{ xml: [], "pin": [] ';
for (i = 0; i < elem.childNodes.length; i++) {
if (elem.childNodes[i].nodeName == "LI") {
jsonGroups = jsonGroups + ', "' + elem.childNodes[i].attributes.getNamedItem("id").value + '": [] ';
}
}
jsonGroups = jsonGroups + "}";
markerGroups = eval('(' + jsonGroups + ')');
for (i = 0; i < elem.childNodes.length; i++) {
if (elem.childNodes[i].nodeName == "LI") {
var elemID = elem.childNodes[i].attributes.getNamedItem("id").value;
if (elemID != "user") {
elem.childNodes[i].innerHTML = "<a onclick='" + 'toggleGroup("' + elemID + '")' + "'>" + elem.childNodes[i].innerHTML + "</a>";
} else {
elem.childNodes[i].innerHTML = '<form id="userPOIForm" action="#" onsubmit="userPOIFind(this.userPOI.value); return false"><input id="userPOITxt" size="20" name="userPOI" value="' + elem.childNodes[i].innerHTML + '" type="text"><input id="userPOIButton" value="Go" type="submit"> </form>';
}
if (hasClass(elem.childNodes[i], "hidden") !== null) {
elem.childNodes[i].setAttribute("caption", "hidden");
} else {
elem.childNodes[i].setAttribute("caption", "");
}
if (elem.childNodes[i].attributes.getNamedItem("caption").value != "hidden") {
classAdder = document.getElementById(elemID);
addClass(classAdder, "visibleLayer");
}
}
}
}
for (i = 0; i < elem.childNodes.length; i++) {
if (elem.childNodes[i].nodeName == "LI") {
var catType = elem.childNodes[i].attributes.getNamedItem("id").value;
result = doSearch(elem.childNodes[i].attributes.getNamedItem("title").value, elem.childNodes[i].attributes.getNamedItem("id").value);
}
}
}
If you are trying to select all elements with an id that starts with cat, you can do this in jQuery like this:
$("[id^=cat]")
jQuery: Attributes Starts With Selector
Just make categoriesList be another parameter, and call the function twice.

An inline configured ckeditor has its toolbar attached to document body. Unless the user didn't focus the editor the toolbar is hidden. If we have multiple inline editors on same page, there will be the same number toolbar DOM elements attached to the body - each one with specific identifier. My question is, if there is a way to have a single toolbar DOM element for multiple inline ckeditors? I know (and I'm using in different context) the shared space plugin which does that, but the drawback is that one should provide an element to which the single toolabar would be attached. That's OK, but it is static and stays at the place where it's placed in the DOM order and I'd like it to be repositioned next to the currently focused editor.
Seems like I either have to use the default inline behavior or to use the shared space plugin and to reposition the single toolbar instance myself.
Any ideas on this issue or something I'm missing?
No, every CKEditor creates its own toolbar. But you can create your own plugin for this which is actually just displaying the toolbar of the active element. I have created one have a look. You do require to configure the your editor config too.
CKEDITOR.plugins.add('grouplabel', {
init : function(editor) {
function getCorrespondingName(no) {
var tempNo = 0;
for (var i = 0; i < editor.config.toolbar.length; i++) {
if (editor.config.toolbar[i].groupName != undefined) {
if (tempNo == no) {
return i;
}
tempNo++;
}
}

Thank you for your efforts, i was working on this, i solved this by only adding this code into function.
if(typeof as != 'undefined' && i==as) { sts = true; html += '<li>...</li>'; }
where the line is
if (typeof as != 'undefined' && i == as) {
sts = true;
}
this script is generating a pagination you can see in script. and the final output is this.
simple pagination without dots.
checkttttNew-Folder-1New-Folder-1New-Folder-1
when exceeds 6 li then it creates dots. like this.
checkttttNew-Folder-1New-Folder-1...New-Folder-1htesttes2
I am trying to use dynamically created IDs in javascript function, but it's not working. I thought that prepending # to string id should work, but it's not.
Code:
var IterateCheckedDatesAndUncheckWithSameValue = function (elementNumber) {
idCheckBoxToCompare = "CMP_KD1_tcDE_tctpDNDR_chkDNDRDay" + elementNumber.toString();
if ($("'#" + idCheckBoxToCompare + "'").prop('checked') === false) {
return;
}
textBoxID = "CMP_KD1_tcDE_tctpDNDR_txtDNDRDay" + elementNumber.toString();
textBoxValue = $("'#" + textBoxID + "'").val();
for (i = 1; i < 8; i++) {
if (i !== elementNumber) {
idCheckBox = "CMP_KD1_tcDE_tctpDNDR_chkDNDRDay" + i.toString();
idInputBox = "CMP_KD1_tcDE_tctpDNDR_txtDNDRDay" + i.toString();
inputBoxValue = $("'#" + idInputBox + "'").val();
if ($("'#" + idCheckBox + "'").prop('checked') === true) {
if (inputBoxValue === textBoxValue) {
$("'#" + idCheckBox + "'").prop('checked', false);
}
}
}
}
}
I've tried to build same id as this is:
'#testid'
so usage would be:
$('#testid')
But it's not working. How to use properly dynamically created IDs?
Your code is look complicated with too many " and '. Also Javascript can concat string and number by just use +. No need to convert it to string first. So, I updated it to make it more readable.
Try this
var IterateCheckedDatesAndUncheckWithSameValue = function(elementNumber) {
idCheckBoxToCompare = "CMP_KD1_tcDE_tctpDNDR_chkDNDRDay" + elementNumber;
if ($('#' + idCheckBoxToCompare).prop('checked') === false) {
return;
}
textBoxID = "CMP_KD1_tcDE_tctpDNDR_txtDNDRDay" + elementNumber;
textBoxValue = $('#' + textBoxID).val();
for (i = 1; i < 8; i++) {
if (i !== elementNumber) {
idCheckBox = "CMP_KD1_tcDE_tctpDNDR_chkDNDRDay" + i;
idInputBox = "CMP_KD1_tcDE_tctpDNDR_txtDNDRDay" + i;
inputBoxValue = $('#' + idInputBox).val();
if ($('#' + idCheckBox).prop('checked') === true) {
if (inputBoxValue === textBoxValue) {
$('#' + idCheckBox).prop('checked', false);
}
}
console.log('#' + idCheckBox); //print here just to see the id results
}
}
}
ID in html can be only one element per page. So please make sure that the ID you generate from this method not match with other.
Jquery selector can read String variable.
So you can just do var id = "#test". Then put it like this $(id).
Or
var id = "test"; then $("#"+test).
Use this,
var IterateCheckedDatesAndUncheckWithSameValue = function (elementNumber) {
idCheckBoxToCompare = "CMP_KD1_tcDE_tctpDNDR_chkDNDRDay" + elementNumber.toString();
if ($("#" + idCheckBoxToCompare).prop('checked') === false) {
return;
}
textBoxID = "CMP_KD1_tcDE_tctpDNDR_txtDNDRDay" + elementNumber.toString();
textBoxValue = $("#" + textBoxID).val();
for (i = 1; i < 8; i++) {
if (i !== elementNumber) {
idCheckBox = "CMP_KD1_tcDE_tctpDNDR_chkDNDRDay" + i.toString();
idInputBox = "CMP_KD1_tcDE_tctpDNDR_txtDNDRDay" + i.toString();
inputBoxValue = $("#" + idInputBox).val();
if ($("#" + idCheckBox).prop('checked') === true) {
if (inputBoxValue === textBoxValue) {
$("#" + idCheckBox).prop('checked', false);
}
}
}
}
}
I face the same problem using Jquery .Try $(document).getElementbyId('myid'). Hope help.
Edit
Change :
$("#" + idCheckBoxToCompare) by $(document).getElementbyId(idCheckBoxToCompare)
I'm running a site using Node, Express and MongoDB. I generate containers after an ajax call to get the data to fill them with, and each of the containers has a button which makes another ajax call specific to a recipe it's getting detailed information on. The first Time I do this it works perfectly, but if i get details for a 2nd one it executes the function 3 times instead of one, and if I do it for a 3rd container it runs it 9 times and so on. I'm fairly new with Jquery and perhaps It's a misunderstanding of how the events work. the problems also occurs with the saveRecipe function.

This line:
$('.details').click(get_data_for_popover_and_display);
hooks up a new event handler on all .detail elements that will call get_data_for_popover_and_display, even if that element already has an event handler calling get_data_for_popover_and_display. Same with:
$('.save-favorite').on('click', saveRecipe );
So since get_data_for_popover_and_display (at least) does another ajax call, which will add another handler, you'll get increasing numbers of handlers over time.
It's exactly like this:
function clickHandler() {
console.log(+new Date(), "Clicked");
clickComplete();
}
function clickComplete() {
$("#btn").on("click", clickHandler);
}
clickComplete();
<input type="button" id="btn" value="Click Me">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
So: Only add a handler if you haven't already done so. Perhaps keep track in jQuery's data store:
function clickHandler() {
console.log(+new Date(), "Clicked");
clickComplete();
}
function clickComplete() {
$("#btn").filter(function() {
return !$(this).data("hasClick");
})
.on("click", clickHandler)
.data("hasClick", true);
}
clickComplete();
<input type="button" id="btn" value="Click Me">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

html_friends_list = html_friends_list + "<li style='font-size:19px' id='open_chat-" + items[count].jid + "'>" + "<a href='chat-js/index.html'>" + display_name + "<span class='block-list-label' id='" + items[count].jid + "_unread_messages" + "'>0</span><span class='block-list-label' id='" + items[count].jid + "_change_status" + "'></span></a></li>";
}
}
document.getElementById("friends-list").innerHTML = html_friends_list;
As a said I want to save the value of the text and the id of any li element clicked.
Regards
you haven't specified whether this is for a specific list or just any li on your page. The below will log the id and innerHTML components of any li on the page. Perhaps you may need to update the querySelector for your particular use case.
var list = document.querySelectorAll('li');
Array.prototype.slice.call(list).forEach(function(listItem){
listItem.addEventListener('click', function(e){
console.log(this.id);
console.log(this.innerHTML);
});
});
Here's a JSFiddle which I think demonstrates what you are trying to achieve.

Combination of james' answer and working example.
function get_friends(items) {
if (items != undefined) {
if (items.length != 0) {
var html_friends_list = "<ul>";
for (var count = 0; count < items.length; count++) {
if (items[count].subscription == "both") {
html_friends_list = html_friends_list + "<li id='open_chat-" + items[count].jid + "'>"+ items[count].display_name +"</li>";
}
}
html_friends_list = html_friends_list + '</ul>'
document.getElementById("friends-list").innerHTML = html_friends_list;
}
}
}
Note: you should trigger prototype after your dom element created.
