I'm trying to create a Vista gadget, I've properly stored my Date1 variable and am trying to pull it:
<html>
<head>
<title>None</title>
<link href="style.css" rel="stylesheet" type="text/css">
<script type="text/javascript">
System.Gadget.settingsUI="settings.html";
System.Gadget.onSettingsClosed = settingsClosed;
function settingsClosed(p_event) {
// if OK button is clicked reload gadget
if (p_event.closeAction == p_event.Action.commit) {
// pull settings from here
text1.value=System.Gadget.Settings.readString("Date1");
}
}
</script>
</head>
<body>
<span class="stext">Last Serviced:<br />
<span id="text1">Nothing Yet</span>
</span>
</body>
</html>
Using the span tag, text1 does not display anything.
However, if i use an input tag:
<input id="text1" type="text" />
Then the data DOES get displayed. What am I doing wrong here?
text1.value=System.Gadget.Settings.readString("Date1");
span tags don't have a value property. try:
span1.innerHTML=System.Gadget.Settings.readString("Date1");
are you sure the <span> tag is to be inside the <script> tag?

I have a folder with two files each, once the HTML file, and once the JS file to make everything clearer. My problem now is that I try to access an ID within the HTML file with the getElementById but this doesn't seem to work.
var score = 0;
score = score + 1;
document.getElementById("score").outerHTML = score;
<!DOCTYPE html>
<head>
<title>Clicker Game</title>
<link rel="stylesheet" href="design.css">
<script src="code.js" type="text/javascript"></script>
</head>
<body>
<p>Cookies: <span id="score">0</span></p>
<img src="images/cookie.png" height="256px" width="256px">
</body>
</html>
I am trying to call the ID "score" in the HTML file to make sure that when I start the HTML file locally the number changes from 0 to 1.
Click on the number in the HTML file, which will change the value. You cannot change the value without a trigger in the HTML. Something needs to be clicked or changed for the value to appear.
Edit: And don't grab the outerHTML of the element. You are erasing the whole score span and replacing it with the count. Use textContent instead.
let elem = document.querySelector("#score");
elem.addEventListener("click", (e) => {
elem.textContent = Number(elem.textContent) + 1;
})
#score {
cursor: pointer;
}

Im trying to add one to a variable on the push of a button in javascript. Here's what I have:
<html>
<head>
</head>
<body>
<script language="javascript" type="text/javascript">
var add = 0;
function add1(){add++}
document.write(add);
</script>
<br/>
<input type="button" value="Add One" onclick="add1()" />
</body>
</html>
Well most likely the variable add is being incremented by 1 when you push the button. However that code isn't really doing what you want.
This is probably more like what you're after:
<html>
<head>
</head>
<body>
<script language="javascript" type="text/javascript">
var add = 0;
function add1(){
add++;
document.getElementById('numberField').innerHTML = add;
}
</script>
<span id="numberField"></span>
<input type="button" value="Add One" onclick="add1()" />
</body>
</html>
When you do document.write(add) it's replacing everything in the body with the value of add.
We moved the "writing the value" piece of code into the function that is called when you press the button. This is so we redraw the number after it has been incremented.
By updating the contents of an html tag instead of the entire page, we don't loose the button. The html tag has the id numberField, and can be accessed with document.getElementById('numberField');.
I am trying to duplicate Expanding Text Areas Made Elegant
Basically it explains how we can achieve something like fb comment box, where its size increases as text files the textarea.
I have this in my index.html:
<html>
<head>
<link rel="stylesheet" type="text/css" href="test.css">
<script src="test.js"></script>
</head>
<body>
<figure>
<div class="expandingArea">
<pre><span></span><br></pre>
<textarea></textarea>
</div>
</figure>
</body>
</html>
And my test.js looks like:
This doesn't really works.
However if I move everything inside the js file to a script tag inside body then it works fine. So my index file would look like:
<html>
<head>
<link rel="stylesheet" type="text/css" href="test.css">
</head>
<body>
<figure>
<div class="expandingArea">
<pre><span></span><br></pre>
<textarea></textarea>
</div>
</figure>
<script>
function makeExpandingArea(container) {
var area = container.querySelector('textarea');
var span = container.querySelector('span');
if (area.addEventListener) {
area.addEventListener('input', function() {
span.textContent = area.value;
}, false);
span.textContent = area.value;
} else if (area.attachEvent) {
// IE8 compatibility
area.attachEvent('onpropertychange', function() {
span.innerText = area.value;
});
span.innerText = area.value;
}
// Enable extra CSS
container.className += ' active';
}var areas = document.querySelectorAll('.expandingArea');
var l = areas.length;while (l--) {
makeExpandingArea(areas[l]);
}
</script>
</body>
</html>
You're not actually using onload
Your formatting is so messed up it's hard to tell, but your init code is in a while loop at the bottom after your onload function.
When you include it in the <head> it runs before any elements exist. That's why the position of it matters.
In your browser(I recommend Chrome for testing) open up the developer tools(via right click and selecting inspect element) and make sure your test.js file's path is correct. Do this by selecting the 'Sources' tab on the top of the developer tools window and then selecting the test.js file on the list of sources.
I also consider it best practice to load your js files at the bottom of your web documents(before the last body tag) to guarantee they load AFTER your dom elements load.
try this in your code:
I have used inside a table andapply a css class "form-control". The properties of this text areas are in side tag in side
html code:
<html>
<body>
<table>
<tr>
<td>Description:</td>
<td><textarea name="DESCRIPTION" id="DESCRIPTION" class="form-control"></textarea></td>
<td></td>
</tr>
</table>
//css-code required inside html:
<style>
textarea.form-control {
height: auto;
resize: none;
width: 300px;
}
</style>
</body>
</html>
It always seems to be a problem and I fail to see why, I'm trying to change element p text by using his ID, element p id="para1" is inside PostEditor.html:
The elementID I want to change is para1 in the following html:
<!DOCTYPE html>
<html>
<head>
<title>Editor</title>
<link href="styles/editor.css" rel="stylesheet" type="text/css" media="screen" />
<script src="scripts/mainScript.js"> </script>
</head>
<body>
<!-- Input fields -->
<div class="center">
<form id=caller method="post">
<p id="para1" class="text"><Strong>Post your message</Strong></p>
<textarea id="textEditor" rows="16" cols="34" name="content"></textarea>
<input type="submit" onclick="urlLoader('caller','posthandler.php')" value="Post">
</form>
</div>
<!-- end Input fields -->
</body>
</html>
The following function is issued by a click on a link inside index.html and displaying the page you are seeing above and is then supposed to change its content:
From index.html I issue the function from link:
<a onclick="postEditing()"> Edit</a>
This line issue the following function:
function postEditing()
{
var result = window.open('PostEditor.html', 'newwindow', 'width=350,' + 'height=350');
result.document.getElementById("para1").innerHTML = "11111111111";
result.document.getElementById("para1").innerText = "11111111111";
result.document.getElementById("para1").value = "11111111111";
}
As you can see I tried three methods. I'd never understand what is the difference between them, but I tried all three and none worked!
It's because you're searching the document of the window which shows the index.html, not the document of the newly opened window. try following:
...
var editorWindow = window.open('PostEditor.html', 'newwindow', 'width=350,' + 'height=350');
editorWindow.document.getElementById("para1").innerHTML = "11111111111";
...
EDIT:
NOW i see the problem: in the function you're trying to access a property of the parameter element, but you don't pass a value for it. So this will end in an error because the accessed object is undefinded!
So you have three options to get it working:
test the parameter (always a good idea): var ID = null; if(element) ID = element.id;
pass a value: <a onclick="postEditing(this)"> Edit</a>
remove the line var ID = element.id;
SOLUTION: (TESTED)
I could not really say why, but the index.html found the para1 and can successfully set the new text. But somehow the new window will reinitialize the old value again.
So you have to do the changing in an handler you run at onLoad:
index.html:
<html>
<head>
<script>
function postEditing() {
var result = window.open('PostEditor.html', 'newwindow', 'width=350,' + 'height=350');
result.onload = function() {
result.document.getElementById("para1").innerHTML = "11111111111";
}
}
</script>
</head>
<body>
<a onclick="postEditing()"> Edit</a>
</body>
</html>
PostEditor.html:
<!DOCTYPE html>
<html>
<head>
<title>Editor</title>
<link href="styles/editor.css" rel="stylesheet" type="text/css" media="screen" />
<script src="scripts/mainScript.js"> </script>
</head>
<body>
<!-- Input fields -->
<div class="center">
<form id=caller method="post">
<p id="para1" class="text"><Strong>Post your message</Strong></p>
<textarea id="textEditor" rows="16" cols="34" name="content"></textarea>
<input type="submit" onclick="urlLoader('caller','posthandler.php')" value="Post">
</form>
</div>
<!-- end Input fields -->
</body>
</html>
I'm fairly sure you will need to query the return result of calling window.open like this:
function postEditing(element)
{
var ID = element.id;
var result = window.open('PostEditor.html', 'newwindow', 'width=350,' + 'height=350');
result.getElementById("para1").innerHTML = "11111111111";
result.getElementById("para1").innerText = "11111111111";
result.getElementById("para1").value = "11111111111";
}
[Untested though]
Your button type is submit, which is posting the form. The object is changing in the DOM, only after the script runs, the DOM is reloaded back to it's original state. Try changing your button type to "button", and you should see the P element change appropriately.
Edit: Here's the HTML I used to determine the above. Keeping the button as "submit" caused me to see the text change and then swap back. The HTML below should keep the text in place. HTH!
<!DOCTYPE html>
<html>
<head>
<title>Editor</title>
<script>
function postEditing(element)
{
document.getElementById('para1').innerHTML = "asdafs";
}
</script>
</head>
<body>
<!-- Input fields -->
<div class="center">
<form id=caller method="post">
<p id="para1" class="text"><Strong>Post your message</Strong></p>
<textarea id="textEditor" rows="16" cols="34" name="content"></textarea>
<input type="button" onclick="postEditing('caller')" value="Post">
</form>
</div>
<!-- end Input fields -->
</body>
</html>
Why could the same action when turned into a function stop working? are there any general rules? here is a very concrete and clear example of this issue.
jQuery Mobile, http://jsbin.com/osovoh/2/edit
in this version, js works well. the label of radio button gets changed instantly.
var radio_elem = $('#edit-new-amount-no-cost');
$("label[for='edit-new-amount-no-cost']").html(radio_elem).append("label changed");
but if you remove the /* s and thus turn the same action into a function triggered by the other button,
function go() {
var radio_elem = $('#edit-new-amount-no-cost');
$("label[for='edit-new-amount-no-cost']").html(radio_elem).append("label changed");
}
the the same code messes formatting of the destination. what's wrong?
If it is inside of the function, the markup change happens AFTER jQuery Mobile renders the page. You'll have to cause jQuery Mobile to re-render the page or element you are modifying.
here is the answer:
<!DOCTYPE html>
<html>
<head>
<meta name="description" content="WORKING: replace text in radiobutton" />
<meta charset=utf-8 />
<title></title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
</head>
<body style="text-align:center">
<div class="form-radios">
<div class="form-item" id="edit-new-amount-no-cost-wrapper">
<label class="option" for="edit-new-amount-no-cost" >
<input type="radio" id="edit-new-amount-no-cost" name="new_amount" value="no_cost" class="form-radio"/>
original label
</label>
</div>
</div>
<input name="click to change the label" type="button" onClick="go()">
<script>
function go(){
$("label[for='edit-new-amount-no-cost'] .ui-btn-text").html("label changed");
}
</script>
</body>
</html>
