I believe js shoulod support:
<script>
text = "This Title";
document.write( text.heading(1));
</script>
but it is not so. Any correction or explanatioin?
Why do you do .heading(1) ??
<script>
text = "This Title";
document.write(text);
</script>
Or you are trying to change title?
document.title = text;
Or you want to add text to particular place on the webpage?
<div id="heading1">
</div>
<div id="heading2">
</div>
<script>
text = "This Title";
text2 = "This is not Title";
document.getElementById('heading1').innerHTML = text;
document.getElementById('heading2').innerHTML = text2;
</script>
I guess you're trying to write <h1>This Title</h1> but there is no heading method in String prototype.
HTML Tag Methods (http://msdn.microsoft.com/en-us/library/ie/ff806183%28v=vs.94%29.aspx) may be a bit confusing cause javascript supports just few of html tags.
If you really need to make String.heading work, try this:
String.prototype.heading = function(level) {
return '<h' + level + '>' + this + '</h' + level + '>';
};
Note: extending prototype of built in objects is generally bad idea.

I need some help on editing elements which are in HTML with JavaScript. Is it possible to change the "text" with javascript? I've tried using document.getElementById but I don't think I'm doing it correctly.
Get the elemet with a query like you would use in css:
var element = document.querySelector('div.header');
Change the content using the textContent property:
element.textContent = "New Content;"
Adding image to content:
document.querySelector('div.header').innerHTML = "<img src='smiley.gif' alt='Smiley face' height='42' width='42'>";
Simple example with "press me" button that calls a function to change text
<html>
<script>
function changeText(){
document.getElementById("header").innerHTML = "changed text";
};
</script>
<body>
<div id="header">text</div>
<button onclick="changeText()">press me</button>
</body>
<html>
<script>
function changeText(){
document.getElementById("header").innerHTML = "changed text";
};
</script>
<body>
<div id="header">text</div>
<button onclick="changeText()">press me</button>
</body>
</html>
if querySelectorAll or getElementsbyClassName there are many ways to alter the text.
My answer is that you must think about your structure of the HTML Document.
You can use every ID only once. It is better to use data-lb="detail" etc. and classes for the div´s
Please see this not as an answer only as an tip.
You can try something like this -
<button id="click">
CLICK
</button>
<div class="header" id="textChange">Text</div>
And then in your JS -
$( "#click" ).click(function() {
$( "#textChange" ).replaceWith( "<h2>New heading</h2>" );
});

How to get an text field text in to an array? Is it possible to get a text from text field and put it in to character array to select each Alphabet and use it in different places?
Like I have a words
Computer
<input type="text" name="name" />
I need it like in different Block Like Name Speel
[C] [o] [m] [p] [u] [t] [e] [r]
Any help appreciated.
What you might want is the following JavaScript:
"Computer".split("")
I think that the main problem is this part: "select each Alphabet and use it in Different Places Like..." so the solution is to use .charAt() function.
<!DOCTYPE html>
<html>
<body>
<p>Click the button to display.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
var str = "How are you doing today?";
var res = str.charAt(0);
document.getElementById("demo").innerHTML = res;
}
</script>
</body>
</html>

I have a page with a "click" button in it.By click "counter" value increases.
How can I :
1) create json file for my divs like:
<div class="text1" id="1">1
<p>
content1
</p>
<audio src="sounds/audio1.mp3"></audio>
</div>
<div class="text2" id="2">2
<p>
content2
</p>
<audio src="sounds/audio2.mp3"></audio>
</div>
2) find information for the div that has "id" equal to counter
3) create the div on each "click"
http://jsfiddle.net/KFUVq/14/
I am assuming you want to create divs based off of the current counter number.
If that is the case I like to create HTML in jquery with arrays...
so this
function createElement(counter){
var newEl = [
'<div class="text'+counter+'" id="'+counter+'">' + counter,
'<p>',
'content' + counter,
'</p>',
'<audio src="sounds/audio'+counter+'.mp3"></audio>',
'</div>'
].join("");
$("#divToAppend").append(newEl);
}
somewhere else
createElement(5);

I have two page page1.php, page2.php and one JS file Control.js.
In page1.php
HTML :
<img src="images/b.jpg" width="31" height="26" id="imgClick1" onClick="return changeImage1(this)" >
In Control.js
function changeImage1() {
document.getElementById("imgClick1").src = "images/b.jpg";
document.getElementById('num1').style.color = "#fff";
document.getElementById("text1").innerHTML = "Hello friend";
}
In page2.php
<div id="text1">
Hello world
</div>
So using JavaScript I am trying to write "hello friend" in the div "text1" of page page2.php when I click the image or the div of page1.php.
Is there any possible way to use JS to solve this problem?
Can we use any how document.getElementById("text1").innerHTML or something like that in the program?
I suggest you make use of the include function of php (provided you absolutely want to keep your text1 div on a separate page), like this on your page1.php file:
include('page2.php');
Make sure that when you do that, page1.php and page2.php are in the same folder, otherwise you may define a path to it like this:
include('/path/to/page2.php');

<div class="main">
<textarea rows ="20" cols="80" name ="output_box" id ="output"></textarea>
</div>
What I want it to do is to add text to that area on a button click like so
<div class="classname" button type =onclick="myFunction()" >
Export
</div>
and this is what it calls
<script>
function myFunction()
{
var obj = document.getElementById("output").innerHTML;
var text = document.createTextNode("Test data");
obj.innerHTML = text;
}
</script>
But after much frustration I cannot figure it out.
Example with the changes below: http://jsfiddle.net/charlescarver/hZw6q/
Your JS should be closer to this:
var obj = document.getElementById("output");
var txt = "Test data";
obj.value = txt;
txt != text
As Matt Ball pointed out, "obj is a string," not an object.
You don't need document.createTextNode as you're using value instead of innerHtml
Your HTML should also be:
<div class="classname" type="button" onClick="myFunction()">
Export
</div>
And not:
<div class="classname" button type =onclick="myFunction()" >
Export
</div>
