EDIT 2 - I decided to create a simple example with jsfiddle.
http://jsfiddle.net/VqA9g/61/
As you can see, I am trying to reference the new div.
EDIT - d/t negative votes and unclear question
I have a linked-list like so:
var struct_list = function () {
this.id = 0;
this.name = 0;
this._head = null;
};
struct_list.prototype = {
// .. adding code , delete code ...
list_contents: function () {
var current = this._head;
while ( current != null ) {
var div = document.createElement("div");
div.style.width = "100px";
div.style.height = "100px";
div.style.background = "white";
div.style.color = "black";
div.style.top = "0px";
div.style.left = "0px";
div.style.margin = "400px 1000px auto";
div.style.cursor = "pointer";
div.innerHTML = current.name;
div.onclick = function ( v ) { var d = document.getElementById('div'); alert(d)};
document.body.appendChild(div);
current = current.next;
}
return null;
},};
I want to be able to display this linked list, and each item displayed be able to interact with an "onclick".
Example:
struct_list.add ( 0 , "Zero" );
struct_list.add ( 1 , "One" );
struct_list.list_contents();
_________________________________________________________________________
| |
| <clickable> "Zero" that does a function(id) that passes over its ID(0) |
|________________________________________________________________________|
| |
| <clickable> "One" <same as above> |
|________________________________________________________________________|
Sorry if I was unclear. Will reedit if still unclear. My apologies.
I have a linked-list struct that I hold data in (it changes data frequently) and I have a setInterval to refresh it. My question is how can I list the struct's contents while still being able to click the exposed content, I have it set up right now that each content in the linked-list contains an id. Also , how can I make sure that overflow is automatic for the y axis? I am guessing I have to place it into a div that has that enabled.
But my real question is how to expose the linked-lists elements while also being able to interact with them via an onclick.
I also do not want to use anything other than pure javascript.
Example (in my mind) would maybe be something like:
<div id="PopUp">
<script>
setInterval(function() {
if ( struct_qued_list ) {
struct_qued_list = false;
main.struct_list.list_contents(); // the linked list
}
}, 100);
</script>
</div>
list_contents: function () {
var current = this._head;
while ( current != null ) {
var div = document.createElement("div");
div.style.width = "100px";
div.style.height = "100px";
div.style.background = "white";
div.style.color = "black";
div.style.top = "0px";
div.style.left = "0px";
div.style.margin = "400px 1000px auto";
div.style.cursor = "pointer";
div.innerHTML = current.name;
div.onclick = function ( v ) { var d = document.getElementById('div'); alert(d)};
document.body.appendChild(div);
current = current.next;
}
return null;
},
Any help or logical way to do this would be appreciated.
This is mainly a scope problem, in your Edit 2 fiddle, the alert gives undefined because your i got the value 2 in order to leave the loop.
Here is a possible solution : Live demo (jsfiddle)
!function(){
var index = i; // Make it independant of i
div.onclick = function () { alert(list[index]); };
}();
You could also use attributes to store any value, and using this in the function to retrieve it.
Or export the whole process to another function to obtain something like this :
for ( var i = 0; i < 2 ; i++ ) {
doSomething(i);
}
When you add new content to the DOM JavaScript sometimes has a hard time picking that up. You may need to use a DOM mutation event (like DOMNodeInserted) to add the event listeners to your text nodes.
document.addEventListener('DOMNodeInserted', function(){
document.getElementById('thing').addEventListener('click', function(){
alert('yey!');
});
});
you may need to name your functions so you can remove them as well, if nodes are going to be inserted without removing all the old ones. Yes this is pure javascript.
EDIT: for your overflow issue, you could assign a class to each node as you insert it and style the class via CSS
.classname {
overflow: auto;
}

Popup won't close when i click close button, i tried debugging with console.log and it looks like closeButton.onclick function doesn't run at all for some reason.
When running close() function manually from the console everything works fine.
class Popup {
constructor(content){
this.div = document.createElement("div");
this.div.className = "block";
//tried positioning popup into the center of the screen, doesn't work yet
this.div.style.position = "fixed";
this.div.style.margin = "auto auto";
//caption
this.caption = document.createElement("div");
this.caption.style.textAlign = "right";
//closeButton
this.closeButton = document.createElement("button");
this.closeButton.textContent = "X";
this.closeButton.onclick = this.close;
document.body.appendChild(this.div);
this.div.appendChild(this.caption);
this.caption.appendChild(this.closeButton);
this.div.innerHTML += content;
}
close(){
this.div.parentNode.removeChild(this.div);
delete this;
}
}
new Popup("close me");
That's how it looks like:
var popup = new Popup("hm hello");
SOLUTION:
The issue was happening because:
I was appending content of the popup right into main div using +=. That made DOM refresh and onclick trigger reset.
this.closeButton.onclick = this.close; here onclick trigger will execute close function and also will overwrite this keyword, so it contains a button that called trigger, not the Popup object. I decided to put Popup into a variable that is visible to onclick function. Now everything works fine.
class Popup {
constructor(content){
this.div = document.createElement("div");
this.div.className = "block";
this.div.style.position = "fixed";
this.div.style.margin = "auto auto";
//делоем капшон
this.caption = document.createElement("div");
this.caption.style.textAlign = "right";
//кнопка закрытия
this.closeButton = document.createElement("button");
this.closeButton.textContent = "X";
let popup = this;
this.closeButton.onclick = function(){popup.close()};
this.content = document.createElement("div");
this.content.innerHTML = content;
this.caption.appendChild(this.closeButton);
this.div.appendChild(this.caption);
this.div.appendChild(this.content);
document.body.appendChild(this.div);
}
close(){
this.div.parentNode.removeChild(this.div);
delete this;
}
}
new Popup("hello guys");
The issue is that right here:
this.div.innerHTML += content;
When you assign a value to .innerHTML, the entire previous value is overwritten with the new value. Even if the new value contains the same HTML string as the previous value, any DOM event bindings on elements in the original HTML will have been lost. The solution is to not use .innerHTML and instead use .appendChild. To accomplish this in your case (so that you don't lose the existing content), you can create a "dummy" element that you could use .innerHTML on, but because of performance issues with .innerHTML, it's better to set non-HTML content up with the .textContent property of a DOM object.
You were also going to have troubles inside close() locating the correct parentNode and node to remove, so I've updated that.
class Popup {
constructor(content){
this.div = document.createElement("div");
this.div.className = "block";
this.div.style.position = "fixed";
this.div.style.margin = "auto auto";
//caption
this.caption = document.createElement("div");
this.caption.style.textAlign = "right";
//closeButton
this.closeButton = document.createElement("button");
this.closeButton.textContent = "X";
this.closeButton.addEventListener("click", this.close);
this.caption.appendChild(this.closeButton);
this.div.appendChild(this.caption);
// Create a "dummy" wrapper that we can place content into
var dummy = document.createElement("div");
dummy.textContent = content;
// Then append the wrapper to the existing element (which won't kill
// any event bindings on DOM elements already present).
this.div.appendChild(dummy);
document.body.appendChild(this.div);
}
close() {
var currentPopup = document.querySelector(".block");
currentPopup.parentNode.removeChild(currentPopup);
delete this;
}
}
var popup = new Popup("hm hello");
I've finally found a final solution.
As Scott Marcus mentioned in his answer, i will have troubles inside close function, so i decided to put Popup object into a variable that is visible to close function. Everything works fine without applying classes. Though it may look like a bad code.
class Popup {
constructor(content){
this.div = document.createElement("div");
this.div.className = "block";
this.div.style.position = "fixed";
this.div.style.margin = "auto auto";
//делоем капшон
this.caption = document.createElement("div");
this.caption.style.textAlign = "right";
//кнопка закрытия
this.closeButton = document.createElement("button");
this.closeButton.textContent = "X";
let popup = this;
this.closeButton.onclick = function(){popup.close()};
this.content = document.createElement("div");
this.content.innerHTML = content;
this.caption.appendChild(this.closeButton);
this.div.appendChild(this.caption);
this.div.appendChild(this.content);
document.body.appendChild(this.div);
}
close(){
this.div.parentNode.removeChild(this.div);
delete this;
}
}
new Popup("hello guys")
P.S.
What's the point of this restriction?
<iframe id="frmFile" src="Book1.txt" onload="generateInventory();" style="display: none;"></iframe>
<script>
function csvpls() {
var oFrame = document.getElementById("frmFile");
var strRawContents = oFrame.contentWindow.document.body.childNodes[0].innerHTML;
while (strRawContents.indexOf("\r") >= 0)
strRawContents = strRawContents.replace("\r", "");
var arrLines = strRawContents.split(",");
return arrLines
}
function generateInventory(a, b) {
var xx = csvpls()
var div = document.createElement("div");

document.getElementById(b).appendChild(div);
}

I am trying to create edit multiple divs with the following code. I hope to call each function with parameters to create the divs and put content in them.
So I have some problems with the code above. First off, document.getElementById(str).appendChild(div); is not working the way I want it to. It works if I put the div id "Q1" instead of b. Just wondering, if I can pass a variable through it. Secondly, when I change the div to "Q1", the div is generated, but the content in there is "Hello undefined Yes". If I call the array with xx[20] instead of xx[a], I would get what I want which is "Hello content yes". Sorry, this probably seems like a nuisance, any help is appreciated.
Hi Im trying to trying to track down a good modern Vanilla Javascript modal/lytebox with iFrame support, essentially I have I number of links like below:
<a class="edit-html" href="/iframe.html?para=123"></a>
That I want to trigger the modal with iframe content, without having to embed anything other than JS/CSS in the page (i.e. no modal markup)
HighslideJS (http://highslide.com/examples/iframe.html) meets the main requirements(although it doesn't have a modern look and isn't open source) does anyone know of any alternatives?
I've had a look at this link http://planetozh.com/projects/lightbox-clones/ although the list looks quite old and only HighSlideJS meets my requirements on that list
So my main requirements are:
Vanilla JS (No dependencies)
Iframe Content determined by href tag
Actively Maintained, ideally on Github
Modal markup does not need to be manually embedded on page
Interesting to try to see how we could accomplish your iframe manipulation in a way that would degrade gracefully without script. The anchor tag attributes can do most of the heavy lifting.

<iframe name="iframe1" src="about:blank""></iframe>
Personally I think the best lightweight approach to dialogs is to use something sparse like the code below. They aren't often required to do much and therefore don't really require much in the way of being "maintained".
Fiddle here.
var Dialog = function(content, config){
/*
content: selector, element, or text to wrap into dialog body
config object parameters:
modal: boolean,
dialogClass: text,
createCallBack, renderCallBack, showCallBack, hideCallBack, toggleCallBack: functions
*/
var self = this;
this.config = config || {};
this.init = function(){
//check for an element passed as content or a selector corresponding to an element
self.content = content.tagName ? content : document.querySelector(content);
if( ! self.content){
//otherwise content is text to be appended to the dialog body
self.content = document.createElement("div");
self.content.innerText = content;
}
self.container = self.create();
self.body.appendChild(self.content);
if(document.body){
self.render();
}else{
document.body.addEventListener("load", self.render);
}
window.addEventListener("resize", function(){
self.size();
})
return self;
}
this.create=function create(){
self.container = document.createElement("div");
self.dialog = document.createElement("div");
self.head = document.createElement("h2");
self.closeButton = document.createElement("button");
self.body = document.createElement("div");
self.head.innerText = self.config.headerText || "";
self.dialog.appendChild(self.head);
self.dialog.appendChild(self.closeButton);
self.container.appendChild(self.dialog);
self.dialog.appendChild(self.body);
self.body.appendChild(self.content);
self.container.className = "dialog-container" + (self.config.modal ? " modal" : "");
self.dialog.className = "dialog " + self.config.dialogClass || "";
self.head.className = "dialog-head";
self.body.className = "dialog-body";
self.closeButton.className = "dialog-close";
self.closeButton.innerText = self.config.closeButtonText || "close";
self.closeButton.title = self.config.closeButtonText || "close"; self.closeButton.addEventListener("click", self.hide);
self.closeButton.setAttribute("type","button");
self.checkCallBack();
return self.container;
}
this.render = function render(){
document.body.appendChild(self.container);
self.checkCallBack(arguments);
return self.dialog;
}
this.show = function(){
setTimeout(function(){
self.container.classList.add("visible");
self.closeButton.focus();
self.checkCallBack(arguments);
return self.container;
},0);
}
this.hide = function hide(){
var iframe = self.dialog.querySelector("iframe");
if(iframe){
iframe.setAttribute("src","about:blank");
}
self.container.classList.remove("visible");
self.checkCallBack(arguments);
return self.container;
}
this.toggle = function(){
if(self.dialog.classList.contains("visible")){
self.hide();
}else{
self.show();
}
self.checkCallBack(arguments);
return self.container;
}
this.size = function(){
var padding = 80;
self.body.style.maxHeight = window.innerHeight - self.head.offsetHeight - padding + "px";
console.log(self.body.style.maxHeight);
return self.body.style.maxHeight;
}
this.checkCallBack = function(args){
var action = arguments.callee.caller.name,
callBackName = action + "CallBack",
args = Array.prototype.slice.call(args || []),
fn = self.config[callBackName];
if(fn){
args.unshift(action);
fn.apply(self, args);
}
return !!fn;
}
this.init();
}
//sample usage
var.modal = new Dialog("iframe", {modal: true});
It works on the premade divs but on the newly made one, it doesn't work. How do I fix that?
Here's the code on the event for changing the zIndex:
$(".widget").mousedown(function (event) {
var ws = document.getElementById("widget-workspace");
var list = ws.children, x=0;
for(x=0;x<ws.children.length;x++){
console.log(ws.children[x].id);
$("#"+ws.children[x].id).css("zIndex", 99);
}
$(this).css("zIndex", 100);
});
Now, here's the code for adding the div:
document.getElementById("widget-dialog-button").onclick = function () {
var ws = document.getElementById("widget-workspace");
var list = ws.children;
var x, w = document.getElementById("select-widget");
var widget = w.options[w.selectedIndex].value;
var c = document.getElementById("select-widget-color");
var color = c.options[c.selectedIndex].value;
var left = 0, top = 25, docWidth = ws.offsetWidth, check;
for(x=0; x < list.length; x++){
docWidth -= 325;
left += 325;
if(docWidth < 325){
check = false;
docWidth = ws.offsetWidth;
left = 0;
top += 210;
}else{
check = true;
}
}
x-=2;
var iDiv = document.createElement('div');
iDiv.id = 'widget_'+x;
iDiv.className = 'widget';
iDiv.style.backgroundColor = color;
iDiv.style.left = left;
iDiv.style.top = top;
ws.appendChild(iDiv);
$(function() {
$( ".widget" ).draggable();
});
};
If you guys need anything else, feel free to ask.
The answer is quite simple :
"It works on the premade divs but on the newly made one, it doesn't work. How do I fix that?"
It's normal :
$(".widget").mousedown(...);
// should be read as (except that a new var is not created)
var $currentlyExistingWidgets = $(".widget");
$currentlyExistingWidgets.mousedown(...);
To each element of class widget currently existing, you bind an event.
If you want to bind events to elements not existing... You have to reconider your way of thinking and then bind an event listener to a container always existing, with an event delegation mechanism and proper filtering.
For example the following code should catch the event for all .widget, created before or after :
// http://api.jquery.com/on/
$('body').on('mousedown', '.widget', function() { ... });
If you want to search and learn, the key concepts are event bubbling and event delegation.
The way you're attaching the mousedown listener means that only the element that exist at that point will be listened to. Use the on method:
// May want to use something other than body
$('body').on('mousedown', '.widget', function() {
console.log('go');
});

Yes, I've searched high and low on Stack Overflow and seen some great solutions to this problem that's been solved time and time again with things like SimpleModal, jQuery.confirm and the like.
Problem is, I am developing for this low level device that doesn't allow for a JS framework to be utilized AND I am having to shoehorn this modal confirm into existing JS.
There is an existing script that I am at liberty to edit (but not rewrite) that does a few things like validate, concatenate a few inputs into a single variable, and more.
The script was written to:
Take some session variables and assign new variable names to them and format accordingly
Present a confirm to the user to see whether they want to use those variables to pre-populate the form on the page
Get some functions ready to validate inputs.
other stuff, like offer an abandonment scenario, among other things
Now, all was good when the "confirm" was in place as the script would pause until an OK or Cancel was provided. I am now presenting a modal on the page that I want to mock this behavior and the only way I can think of doing it is to remove that reliance on the line that goes through the confirm thing and NOT run the script until the user interacts with the modal.
Does anyone have an idea how to take what's in place and "wrap" it in a "listening" if/else scenario for each of the YES or NO possibilities?
Sorry if this is jumbled... my brain is all blended up at the moment, too.
As far as I know there is - so far - no way to halt scripts like the Browser specific alert() or confirm() Dialog does.
Frameworks like dojo for example try to mock this behaviour by putting a transparent DIV over the whole window to prevent clicks or other input while the Dialog is showing.
This is quite tricky as I have experienced, since Keyboard-Input may be able to activate Input Fields or Buttons behind this curtain. Keyboard Shortcuts or Field-Tabbing for example.
One sollution is to disable active Elements manually, which works quite well with me in most cases.
One or more function is passed to this "mock" Dialog to execute when an option was chosen.
Escpecially with ajax background activity the responsibilty to stop conflicting function calls while the Dialog is open lies with the developer.
Here is an example I came up with:

In this code there is still an error concerning the availability of the stored choice-function (undefined) at execution time. The function variable is no longer available in the closure. If anyone has a sollution for this you are welcome to add to it.
Hope that comes near to what you need to know.
Updated version: fixed choiceAction undefined, added IE compatibility. Internet Explorer is one main reason to use this, since confirm() is now blocked by default.
