There are loads of tools online that'll do this for you, such as http://procssor.com/

Or without jQuery,



function sendFields(e) {
e.preventDefault();
var form = e.srcElement ? e.srcElement : e.target;
var username = form.username.value;
var realname =...

It might be a bit neater if you create SVG elements and append them to the world element instead of creating a string and updating the innerHTML, you could create a function that automates the...

This part of the example I gave is the AJAX request



var xhr = new XMLHttpRequest();
xhr.open("GET","keywordsearch.php?search="+search,true);
xhr.send();
...

You'll need to use some Ajax to search for keywords asynchronously (without reloading the page). You need to create a separate PHP script to process the Ajax request sent from JavaScript. Here's a...

The second script should work, you seem to be missing a capital F on "uploadedFile" though.

As far as I've gathered from my short experience of working with APIs, you pretty much set your own standard. As long as you keep everything consistent and do return some form of success/error...

You could format it using the date function



$date = date("Y-m-d",strtotime($clo_date));
echo $date;

Remember though that offsetHeight returns the full height of the element, including any padding, using the getComputedStyle method gives you the value you've set the height at.

The div doesn't have a height attribute on it so "getAttribute('height')" won't work in this instance.

You could change the getHeight function to something like this to get the height of the div
...

You might have to change it to something like



if ( chkbx.checked ) {
submitBtn.removeAttribute('disabled');
}
else {
submitBtn.setAttribute('disabled','true');
}

Sounds like an issue caused by you not sanitizing your input, try moving to a database extension that supports prepared statements like PDO.

Well when I said save and update the records list I meant outputting the list with buttons again with the new array, something like this http://jsfiddle.net/pQ5R2/

You could do it by making a button for each record, making a note of which index that record appears at in the history array (maybe as a data attribute on the button), then when the button is clicked...

In this part



if (localStorage.getItem("history") === null) {
document.getElementById("history").innerHTML = "There are currently no records to display.";
} else {...

It's because of the return statement, once the function has returned something it stops being executed, so the loop ends after its first iteration.

You're also passing "Normal" into the difficulty array, I think that's supposed to be "Medium"

You're defining your difficulty array before you define you're easy/medium/hard arrays, so you're adding a bunch of undefined variables.

The square brackets indicate that it's an array, so your example there is an array containing 2 strings.

If you want to output both of the strings you could do something like this



for(var i...

Yeah the quality of a bitmap image defines how "smooth" or unpixelated it looks, take this example, the curve on the left is drawn using canvas, a bitmap technology, while the curve on the right is...

I think we're getting mixed up between image pixels and monitor pixels, sure the physical monitor displays it using pixels but the image itself isn't pixel based at all, and the browser doesn't treat...

A bitmap image is built up out of little dots of colour called pixels, an SVG image is built using solid blocks of colour with their outline defined using math allowing them to be scaled by...

SVG graphics don't use pixels, they use math to draw lines and shapes in specific places, so when you resize an SVG image you aren't "stretching" the pixels like with a bitmap image, the SVG image is...

You could do it using a couple of preg_matches



$file = file_get_contents("datafile.txt");
$date = preg_match("/[0-9][0-9]\-[0-9][0-9]\-[0-9][0-9]...

It's a CSS problem, this'll fix it



h1 {
margin: 0;
}
