Trying to auto format some HTML in CodeMirror V4. Found the docs on how to do it but it looks like the call editor.autoFormatRange(range.from, range.to) was removed in V3...
Code for V2 is below.
Anyone know how to do it with V4 today?
From: http://codemirror.net/2/demo/formatting.html
<script>
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
lineNumbers: true,
mode: "htmlmixed"
});
CodeMirror.commands["selectAll"](editor);
function getSelectedRange() {
return { from: editor.getCursor(true), to: editor.getCursor(false) };
}
function autoFormatSelection() {
var range = getSelectedRange();
editor.autoFormatRange(range.from, range.to);
}
function commentSelection(isComment) {
var range = getSelectedRange();
editor.commentRange(isComment, range.from, range.to);
}
</script>
If you put the formatting.js file in the addons folder of codemirror 4 and reference it, the functions will work.
Location: addon/format/formatting.js
include the script file in your html
Call the formatting code (example at http://codemirror.net/2/demo/formatting.html)
formatting.js

You can use any 3rd party formatting tools, like JS Beautifier (it supports CSS, HTML and JS)
Add custom button
Add onclick handler for it
Use editor.getValue() and editor.setValue(string) from API
jQuery(function($) {
var editor = CodeMirror.fromTextArea($('#code')[0], {
lineNumbers: true,
mode: 'text/javascript',
theme: 'oceanic-next'
});
$('#format').on('click', function() {
editorContent = editor.getValue();
editorContent = js_beautify(editorContent, {indent_with_tabs: true});
editor.setValue(editorContent);
editor.refresh();
});
});

I load it in this way in functions.php in Wordpress:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
It works fine.
Now i duplicate the same javascript code and i called it stickybar.js. I add some modifications, also change class with name "stickybar":
The code of the stickybar.js is here (i pasted it in jsfiddle because there is too much text for stackoverflow)
Then i show this second bar (stickybar.js) only on mobile device and after 8 second with this CSS:
.stickybar { display: none; }
#media only screen and (max-device-width:480px) {
.stickybar {
display: block;
animation: cssAnimation 0s 8s forwards;
visibility: hidden;
}
#keyframes cssAnimation {
to { visibility: visible; }
}
}
I load it in Wordpress with this code in functions.php:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
It works fine.
If i load one by one of this codes, they work fine.
The problem is that when i load the two scripts together in this way in functions.php, only the first works:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
How can i load the two scripts together?
The comment thread on this question is semantically correct, you can only have one instance of each html id attribute, they must be unique, and your find_script_by_id methods are both searching for the same thing.
However, you're doing what's generally called "baking in" the scripts into your header which is at best, a faux pas, at least as far as WordPress is concerned. Properly Enqueueing Scripts (and styles) is very easy in WordPress, and your future self, web clients, and other people who look at your code will thank you for doing it.
It's not unlike how you're "baking in" the scripts now:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
But with a few things changed:
function enqueue_my_scripts(){
wp_enqueue_script( 'cookie-bar', 'https://www.examplesite123.com/cookiebar.js', array(), '1.0', true );
wp_enqueue_script( 'sticky-bar', 'https://www.examplesite123.com/stickybar.js', array(), '1.0', true );
}
add_action( 'wp_enqueue_scripts', 'enqueue_my_scripts' );
Namely, it uses the wp_enqueue_script() function on the wp_enqueue_scripts hook. This lets you defer the script to the footer, load in the header, add version numbers to prevent caching issues, add dependencies, allows you to dynamically add/remove them programatically,gives them unique ID's based on the handle, and much more. (You do still need to update your find_script_by_id functions to use these new handles instead cookie-bar, sticky-bar, change the global_instance_name, etc. (more on that in a second)
With that said, if the .js files are on your server, you'll want to use site_url(), plugins_url(), get_stylesheet_directory_uri(), or similar functions to grab the URL of the file instead of typing it out. If you're using a remote resource, don't worry about it, but if they're on you're site, you should swap out the baked in version for that so you don't have issues if you ever move your site, and it allows you easier methods to edit the version to prevent caching problems if you change them.
Back to your variables, you may also want to replace your find_script_by_id type functions with document.currentScript instead, to allow them to be more abstract and not rely on typo/duplicate prone element IDs, and instead reference the currently running <script> tag.
I'm currently working on a project, where I'm using the following slider in the overal site:
S3Slider
For the particular page I'm currently working on I'm also making use of Walter Zorns' Drag&Drop image library. (Link Here)
Now when I start to make use of the SET_DHTML function, which is required for using the D&D library, my slider starts throwing errors:
Uncaught TypeError: Cannot read property 'contains' of null
The line number given, sends me to the following line:
if($(itemsSpan[currNo]).css('bottom') == 0) {
Which lies in the following piece of code:
s3Slider = function(id, vars) {
var element = this;
var timeOut = (vars.timeOut != undefined) ? vars.timeOut : 2000;
var current = null;
var timeOutFn = null;
var faderStat = true;
var mOver = false;
var items = $("#sliderContent .sliderTopstory");
var itemsSpan = $("#sliderContent .sliderTopstory span");
items.each(function(i) {
$(items[i]).mouseover(function() {
mOver = true;
});
$(items[i]).mouseout(function() {
mOver = false;
fadeElement(true);
});
});
var fadeElement = function(isMouseOut) {
var thisTimeOut = (isMouseOut) ? (timeOut/2) : timeOut;
thisTimeOut = (faderStat) ? 10 : thisTimeOut;
if(items.length > 0) {
timeOutFn = setTimeout(makeSlider, thisTimeOut);
} else {
console.log("Poof..");
}
}
var makeSlider = function() {
current = (current != null) ? current : items[(items.length-1)];
var currNo = jQuery.inArray(current, items) + 1
currNo = (currNo == items.length) ? 0 : (currNo - 1);
var newMargin = $(element).width() * currNo;
if(faderStat == true) {
if(!mOver) {
$(items[currNo]).fadeIn((timeOut/6), function() {
/* This line -> */if($(itemsSpan[currNo]).css('bottom') == 0) {
$(itemsSpan[currNo]).slideUp((timeOut/6), function( ) {
faderStat = false;
current = items[currNo];
if(!mOver) {
fadeElement(false);
}
});
} else {
$(itemsSpan[currNo]).slideDown((timeOut/6), function() {
faderStat = false;
current = items[currNo];
if(!mOver) {
fadeElement(false);
}
});
}
});
}
} else {
if(!mOver) {
if($(itemsSpan[currNo]).css('bottom') == 0) {
$(itemsSpan[currNo]).slideDown((timeOut/6), function() {
$(items[currNo]).fadeOut((timeOut/6), function() {
faderStat = true;
current = items[(currNo+1)];
if(!mOver) {
fadeElement(false);
}
});
});
} else {
$(itemsSpan[currNo]).slideUp((timeOut/6), function() {
$(items[currNo]).fadeOut((timeOut/6), function() {
faderStat = true;
current = items[(currNo+1)];
if(!mOver) {
fadeElement(false);
}
});
});
}
}
}
}
makeSlider();
};
Why is this error being thrown?
Thanks.
I think your problem lies in these two lines:
var currNo = jQuery.inArray(current, items) + 1
currNo = (currNo == items.length) ? 0 : (currNo - 1);
If jQuery doesn't find the item in the array, it's going to send you a value of -1 (on the top line) which will then be changed to 0 because you added 1. Now, if currNo is 0 on the second line, it's going to change it back to -1, which will return you undefined. Maybe try and change it to do this instead:
var currNo = jQuery.inArray(current, items);
if (currNo === items.length - 1) {
currNo = 0;
}
I'm not positive this is the problem, but I can see this becoming an issue if it's not the problem you're currently having.
I use jquery auto complete on my site I have many keywords in auto complete script so my site load slow please tell me any method to load jquery auto complete when user type something on search box this will help to load page fast.

Try to avoid triggering auto completing for the single key entry;Wait at least user enter three key board inputs.
And if your keep your key words in a static array it wont be affect to the speed of the page load.
But the size of your images, .css files, .js files will directly affect to speed of the page load.
try to compress those files and use light weight images.
And try to reduce the round trip time. In order to do that use your basic styling in your html page.
and do research in how to reduce the page load time.
and check your site with google developer page speed insights (https://developers.google.com/speed/pagespeed/insights/)
and read the tips.....
I'm facing weird behaviour of Jit Infovis i'm using. I have two different html files that include a load json function from a Javascript file. The function is using infovis library to display a hypertree map from a json file. Both two html files load the same json file.
One html file has been succeeded rendering the map properly. But another one has not. It renders the map almost properly, but after i debugged it, i got it not iterating over the root node. Then, the root node becames inactive without label and clickability.
This is the js function i'm using.
var labelType, useGradients, nativeTextSupport, animate;
(function () {
var ua = navigator.userAgent,
iStuff = ua.match(/iPhone/i) || ua.match(/iPad/i),
typeOfCanvas = typeof HTMLCanvasElement,
nativeCanvasSupport = (typeOfCanvas == 'object' || typeOfCanvas == 'function'),
textSupport = nativeCanvasSupport
&& (typeof document.createElement('canvas').getContext('2d').fillText == 'function');
//I'm setting this based on the fact that ExCanvas provides text support for IE
//and that as of today iPhone/iPad current text support is lame
labelType = (!nativeCanvasSupport || (textSupport && !iStuff)) ? 'Native' : 'HTML';
nativeTextSupport = labelType == 'Native';
useGradients = nativeCanvasSupport;
animate = !(iStuff || !nativeCanvasSupport);
})();

What's probably causing this?
Please check whether there is conflict id. Basically infovis render each nodes by the id.
And if there is an DOM element that has the same id with one DOM element of a node. It would conflict and won't render
you can check it by duming dom element iterating over the nodes.
I am trying to create collapsible DIVs that react to links being clicked. I found how to do this using "next" but I wanted to put the links in a separate area. I came up with this which works...
JSFiddle - Works
function navLink(classs) {
this.classs = classs;
}
var homeLink = new navLink(".content-home");
var aboutLink = new navLink(".content-about");
var contactLink = new navLink(".content-contact");
var lastOpen = null;
$('.home').click(function() {
if(lastOpen !== null) {
if(lastOpen === homeLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-home').slideToggle('slow');
lastOpen = homeLink;
}
);
$('.about').click(function() {
if(lastOpen !== null) {
if(lastOpen === aboutLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-about').slideToggle('slow');
lastOpen = aboutLink;
}
);
$('.contact').click(function() {
if(lastOpen !== null) {
if(lastOpen === contactLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-contact').slideToggle('slow');
lastOpen = contactLink;
}
);
I am now trying to create the same result but with a single function instead of one for each link. This is what I came up with....
function navLink(contentClass, linkClass, linkId) {
this.contentClass = contentClass;
this.linkClass = linkClass;
this.linkId = linkId;
}
var navs = [];
navs[0] = new navLink(".content-home", "nav", "home");
navs[1] = new navLink(".content-about", "nav", "about");
navs[2] = new navLink(".content-contact", "nav", "contact");
var lastOpen = null;
$('.nav').click(function(event) {
//loop through link objects
var i;
for (i = 0; i < (navsLength + 1); i++) {
//find link object that matches link clicked
if (event.target.id === navs[i].linkId) {
//if there is a window opened, close it
if (lastOpen !== null) {
//unless it is the link that was clicked
if (lastOpen === navs[i]) {
return;
} else {
//close it
$(lastOpen.contentClass).slideToggle('fast');
}
}
//open the content that correlates to the link clicked
$(navs[i].contentClass).slideToggle('slow');
navs[i] = lastOpen;
}
}
});
JSFiddle - Doesn't Work
No errors so I assume that I am just doing this completely wrong. I've been working with Javascript for only about a week now. I've taken what I've learned about arrays and JQuery events and tried to apply them here. I assume I'm way off. Thoughts? Thanks
You just forgot to define navsLength:
var navsLength=navs.length;
Of course you could also replace it with a $().each loop as you're using jQuery.
[Update] Two other errors I corrected:
lastOpen=navs[i];
for(i=0; i < navsLength ; i++)
Demo: http://jsfiddle.net/jMzPJ/4/
Try:
var current, show = function(){
var id = this.id,
doShow = function() {
current = id;
$(".content-" + id).slideToggle('slow');
},
toHide = current && ".content-" + current;
if(current === id){ //Same link.
return;
}
toHide ? $(toHide).slideToggle('fast', doShow): doShow();;
};
$("#nav").on("click", ".nav", show);
