Adding multi-line javascript to a page via DOM

Adding multi-line javascript to a page via DOM - javascript

I'm tinkering with some things, more just experimenting and learning how DOM manipulation works.
<script type="text/javascript">
(function()
{
var config = {
};
var get = CKFinder.tools.getUrlParam;
var getBool = function( v )
{
var t = get( v );
if ( t === null )
return null;
return t == '0' ? false : true;
};
var tmp;
if ( tmp = get( 'basePath' ) )
CKFINDER.basePath = tmp;
if ( tmp = get( 'startupPath' ) )
config.startupPath = decodeURIComponent( tmp );
config.id = get( 'id' ) || '';
if ( ( tmp = getBool( 'rlf' ) ) !== null )
config.rememberLastFolder = tmp;
if ( ( tmp = getBool( 'dts' ) ) !== null )
config.disableThumbnailSelection = tmp;
if ( tmp = get( 'data' ) )
config.selectActionData = tmp;
if ( tmp = get( 'tdata' ) )
config.selectThumbnailActionData = tmp;
if ( tmp = get( 'type' ) )
config.resourceType = tmp;
if ( tmp = get( 'skin' ) )
config.skin = tmp;
if ( tmp = get( 'langCode' ) )
config.language = tmp;
// Try to get desired "File Select" action from the URL.
var action;
if ( tmp = get( 'CKEditor' ) )
{
if ( tmp.length )
action = 'ckeditor';
}
if ( !action )
action = get( 'action' );
var parentWindow = ( window.parent == window )
? window.opener : window.parent;
switch ( action )
{
case 'js':
var actionFunction = get( 'func' );
if ( actionFunction && actionFunction.length > 0 )
config.selectActionFunction = parentWindow[ actionFunction ];
actionFunction = get( 'thumbFunc' );
if ( actionFunction && actionFunction.length > 0 )
config.selectThumbnailActionFunction = parentWindow[ actionFunction ];
break ;
case 'ckeditor':
var funcNum = get( 'CKEditorFuncNum' );
if ( parentWindow['CKEDITOR'] )
{
config.selectActionFunction = function( fileUrl, data )
{
parentWindow['CKEDITOR'].tools.callFunction( funcNum, fileUrl, data );
};
config.selectThumbnailActionFunction = config.selectActionFunction;
}
break;
default:
if ( parentWindow && parentWindow['FCK'] && parentWindow['SetUrl'] )
{
action = 'fckeditor' ;
config.selectActionFunction = parentWindow['SetUrl'];
if ( !config.disableThumbnailSelection )
config.selectThumbnailActionFunction = parentWindow['SetUrl'];
}
else
action = null ;
}
config.action = action;
// Always use 100% width and height when nested using this middle page.
config.width = config.height = '100%';
var ckfinder = new CKFinder( config );
ckfinder.replace( 'ckfinder', config );
})();
</script>
What I am trying to figure out how to do, is add that code to a page through the DOM. I know I can do it if I put this function in a >JS file, as I know how to call .JS files and have them load properly.
If I wanted to write that script out, as shown there, directly on the page, how would I do that? I have found some simple examples, like this:
window.onload = function() {
var s = document.createElement('script');
s.type = 'text/javascript';
var code = 'alert("hello world!");';
try {
s.appendChild(document.createTextNode(code));
document.body.appendChild(s);
} catch (e) {
s.text = code;
document.body.appendChild(s);
}
}
But it doesn't seem to work when I put a long, multi-line, block of javascript in it. How can I do this?

DOM is a Tag based mark up structure. So a defined structure of Tags has to come in a defined order. Everything in DOM goes in Tags. If you want JavaScript in DOM, that will also be added to a Script Tag.
Within this tag you can put all your JavaScript and that will be just in the page for you.
Following link contains a JavaScript JQuery example that is the code on the same page and it is a very beginner level article with a detail on how to use Script on the page and how to use event handling etc.

jQuery html property...?

Alright... My HTML looks like this:
<div id="_content"></div>
And then, there is a method like this:
Main.LoadContent(source, target)
{
var reader = new FileReader();
var s = '';
reader.onload = function()
{
s = reader.result;
var t = $(target).html;
alert(t);
t.html = s;
}
var f = new File([""], source);
reader.readAsText(f);
}
Mind the 'alert(t)' line, it returns:
function ( value ) {
return access( this, function( value ) {
var elem = this[ 0 ] || {},
i = 0,
l = this.length;
if ( value === undefined ) {
return elem.nodeType === 1 ?
elem.innerHTML.replace( rinlinejQuery, "" ) :
undefined;
}
// See if we can take a shortcut and just use innerHTML
if ( typeof value === "string" && !rnoInnerhtml.test( value ) &&
( support.htmlSerialize || !rnoshimcache.test( value ) ) &&
( support.leadingWhitespace || !rleadingWhitespace.test( value ) ) &&
!wrapMap[ (rtagName.exec( value ) || [ "", "" ])[ 1 ].toLowerCase() ] ) {
value = value.replace( rxhtmlTag, "<$1></$2>" );
try {
for (; i < l; i++ ) {
// Remove element nodes and prevent memory leaks
elem = this[i] || {};
if ( elem.nodeType === 1 ) {
jQuery.cleanData( getAll( elem, false ) );
elem.innerHTML = value;
}
}
elem = 0;
// If using innerHTML throws an exception, use the fallback method
} catch(e) {}
}
if ( elem ) {
this.empty().append( value );
}
}, null, value, arguments.length );
}
The call to Main.LoadContent looks like this:
Main.LoadContent('start.htf', '#_content');
What's my sublime stupidity come to here...???

HTML is a function... put the s variable inside of the function to set the HTML... see what that gets you. Example:
Main.LoadContent(source, target)
{
var reader = new FileReader();
var s = '';
reader.onload = function()
{
s = reader.result;
var t = $(target).html();
alert(t);
//t.html(s);
$(target).html(s);
}
var f = new File([""], source);
reader.readAsText(f);
}

video iframe is not displaying the video wordpress https error

I am using a customized version of the gridby theme I have been adding some new page templates and editing some css over past few days and now I have noticed that the video iframe isnt displaying the actual video. When I inspect the element I can see the area it should be is highlighted. The theme uses a video url field to display a iframe of a video in the single post but I am really stuck now trying to figure out why its not working it was fine few weeks ago I just haven't noticed until now so don't know how to find the error. You can see the post in question here. thanks in advance

Try posting the video on another blank, new page and see if the video works on a different page with a white background.
Also, try making the video a smaller size.
These are some simple tests to see if it works on another page first. Let me know.

I figured out the problem. My site runs off https but the link for the video was set to be http so ssl certifcate was preventing the iframe from loading. I edited the video support php file in the gridby plugin and changed it to http and its working now. I found the solution here: How to fix a website with blocked mixed content

How to further enhance this code?

$( document ).ready( function() {
var dynamicChargableForm = 1;
var dynamicDiscountForm = 1;
var selectedId = 1;
var newTextarea = null;
var chargableHeader = document.getElementById( 'chargable-header' );
var disountHeader = document.getElementById( 'discount-header' );
var execute = null;
$(document).on('keyup','.dynamic',function() {
var typeName = this.id.split('-')[0];
switch( typeName ) {
case 'chargable':
execute = dynamicRow( this, 'chargable', dynamicChargableForm , chargableHeader );
execute ? dynamicChargableForm++ : execute = null;
break;
case 'discount' :
execute = dynamicRow( this, 'discount', dynamicDiscountForm, disountHeader );
execute ? dynamicDiscountForm++ : execute = null;
break;
}
});
});
function dynamicRow( element, type , relatedTracker , relatedHeader )
{
selectedId = element.id.split('-')[1];
if ( selectedId == relatedTracker )
{
relatedTracker++;
newTextarea = document.createElement( 'TEXTAREA' );
newTextarea.setAttribute( 'name', type + '-' + relatedTracker );
newTextarea.setAttribute( 'class' , 'form-control dynamic ' + type );
newTextarea.setAttribute( 'id' , type + '-' + relatedTracker );
relatedHeader.append( newTextarea );
return true;
}
return false;
}
This is my first attempt to add a dynamically populate textarea when user input on the last added form . I would like to have advise and review on my code as i think that this code is not very efficient. I would like to have better understanding and standpoint from the expert.
Thank you

Replace
execute = dynamicRow( this, 'chargable', dynamicChargableForm , chargableHeader );
execute ? dynamicChargableForm++ : execute = null;
By
if(dynamicRow( this, 'chargable', dynamicChargableForm , chargableHeader )) {
dynamicChargableForm++;
}
I don't know why you need to add the dynamic name. Best way would be to set the name to chargable[]. The field will then be sent to the server as array.

Get margin top with JavaScript

I need to get margin-top of an input with JavaScript. This is the jQuery code which works fine:
alert($("#input").css('margin-top'))
But I need it in pure Javascript, I have tried the following code with no luck
alert(document.getElementById('input').style.marginTop)
How can I make it work in pure JavaScript?

I just found a solution:
var style = window.getComputedStyle(document.getElementById('input'));
var marginTop = style.getPropertyValue('margin-top');
alert(marginTop);

Here is a stand-alone version of curCSS from jQuery. Please note the edit that I made to keep the code size down. It hasn't caused me any problems thus far.
//Get current CSS - from jQuery-1.9.0
var curCSS;
(function(){
/*!
* Copyright 2005, 2012 jQuery Foundation, Inc. and other contributors
* Released under the MIT license
* http://jquery.org/license
*/
var getStyles, core_pnum = /[+-]?(?:\d*\.|)\d+(?:[eE][+-]?\d+|)/.source,
rmargin = /^margin/, rnumnonpx = new RegExp( "^(" + core_pnum + ")(?!px)[a-z%]+$", "i" );
if(window.getComputedStyle){
getStyles = function(elem){return window.getComputedStyle( elem, null )};
curCSS = function( elem, name, _computed ){
var width, minWidth, maxWidth, computed = _computed || getStyles( elem ),
ret = computed ? computed.getPropertyValue( name ) || computed[ name ] : undefined,
style = elem.style;
if( computed ){
/* Edit - removed edge case as requires lots more jQuery code
if ( ret === "" && !jQuery.contains( elem.ownerDocument, elem ) ) {ret = jQuery.style( elem, name )}*/
if( rnumnonpx.test( ret ) && rmargin.test( name )){
width = style.width; minWidth = style.minWidth; maxWidth = style.maxWidth;
style.minWidth = style.maxWidth = style.width = ret; ret = computed.width;
style.width = width; style.minWidth = minWidth; style.maxWidth = maxWidth}}
return ret;
}
}
else if (document.documentElement.currentStyle){
getStyles = function( elem ){return elem.currentStyle};
curCSS = function( elem, name, _computed ){
try{
var left, rs, rsLeft, computed = _computed || getStyles( elem ),
ret = computed ? computed[ name ] : undefined, style = elem.style;
if( ret == null && style && style[ name ] ) {ret = style[ name ]}
if( rnumnonpx.test( ret ) && !rposition.test( name ) ) {
left = style.left; rs = elem.runtimeStyle;rsLeft = rs && rs.left;
if ( rsLeft ) {rs.left = elem.currentStyle.left}
style.left = name === "fontSize" ? "1em" : ret; ret = style.pixelLeft + "px";
style.left = left; if ( rsLeft ) {rs.left = rsLeft}}
return ret === "" ? "auto" : ret
}

Coding DRY how to combine common functionality in these two objects?

DRY - Don't Repeat Yourself
ControlSignUp and ControSignIn are nearly identical. I've commented a "here" on the only 4 lines which are different. How can I combine this common functionality?
Actually it seem obvious..I can just pass in a single variable through the constructor...just a sec.
Answer:
/**
* ControlSign
*/
var ControlSign = function( type )
{
var form_element = document.getElementById( type );
var response_element = document.getElementById( type + '_response' );
var text_object = new Text( form_element );
var message_object = new Message( response_element );
this.invoke = function( )
{
if( Global.validate_input_on === 1 )
{
if( !text_object.checkEmpty() )
{
message_object.display( 'empty' );
return false;
}
if( type === 'signup' && !text_object.checkPattern( 'name' ) )
{
message_object.display( 'name' );
return false;
}
if( !text_object.checkPattern( 'email' ) )
{
message_object.display( 'email' );
return false;
}
if( !text_object.checkPattern( 'pass' ) )
{
message_object.display( 'pass' );
return false;
}
}
AjaxNew.repeatUse( ajaxSerialize( form_element ) + '&ajax_type=' + type + '_control', function( server_response_text ) { ajaxType( server_response_text, response_element, 'respond' ); } );
}
};
ControlSign.in = function()
{
new ControlSignIn( 'signin' ).invoke();
};
ControlSign.up = function()
{
new ControlSignUp( 'signup' ).invoke();
};

Simple solution: Make it a function ControlSign with a parameter, invoked with "in" or "up". You could call this "factory pattern".
Complex solution: you use a factory function to create the two constructors. OK, what I meant is the use of a closure to create constructors:
function makeControlSign(type) {
function constructor(...) {
this.invoke = function(){...};
// use the variable "type" where needed
...
}
constructor[type] = function(){...};
return constructor;
}
var ControlSignUp = makeControlSign("up");
var ControlSignIn = makeControlSign("in");
I guess this should neither be called "factory pattern" nor "abstract factory pattern".
