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" />

I have a simple request for you brainies today. What i am trying to do is to activate a pop-up inside PHP tags. I have tested to see if the pop-up works by itself, and it does. My problem is the button, i have used the same setup elsewhere, but this time no cigar. I have also tried echoing the button inside the PHP tags but nothing happens.
My code:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="Lib\JqueryUIcss.css">
<script src="Lib\Jquerylib.js"></script>
<script src="Lib\JqueryUI.js"></script>
</head>
<body>
<button type=" button" class="LeButton"> Clicky Clicky!</button>
<?php
if(isset($_POST['LeButton'])){
echo'<script> $(function() { $( "#dialog" ).dialog(); }); </script>';
echo'<div id="dialog" title="Basic dialog">';
echo'<p>Image:</p>'; </div>';}
?>
</body>
</html>
I tried specifying it as a function aswell and added onclick() to the button to call that function, nothing happend either. Mind that this is the first time i am ever using Javascript/jQuery.
I (kindly) lauched a bit about the echo <script> part.
Allow me to write you a piece of code, with explanation and documentation:
HTML button:
<button type="button" id="LeButton" class="LeButton"> Clicky Clicky! </button>
&
<div id="dialog" title="Basic dialog" style="visibility:hidden"><p>Image:</p> <img src="http://placehold.it/50x50" alt="Placeholder Image" /></div>
Explanation:
Your button needs an id value. Which is called 'LeButton' in this example.
Documentation:
https://www.w3schools.com/tags/att_id.asp
jQuery part:
<script>
jQuery(document).ready(function() {
/**
* #version 1.0.0.
*
* Do magic on button click 'LeButton'
*/
$("#LeButton").click(function() {
$("#dialog").css("visibility", 'visible'); // make the div visible.
$("#dialog").dialog(); // Post here your code on forexample poping up your modal.
});
});
</script>
Explanation:
Your tag can be placed on the bottom of your page. Your browser will 'read' the whole page. By saying '(document).ready', your script will be executed once the page has been red by your browser.
For the '.click' part it's a jQuery function you can use. So which
means: once id attribute 'LeButton' (#) is clicked, jQuery will
execute a function, which will alert text in this case.
Documentation:
https://api.jquery.com/click/
Note: Make sure you have jQuery included/enabled.

Note from Simon Jensen:
You should elaborate that the Class-attribute is for styling and the
Id-attribute can be for whatever code or identifying purposes and are
unique. Therefore should people be careful with styling with the
Id-attribute as things might conflict at some point. The ID-attribute
is used to interact with the "#LeButton" attribute.
The PHP can't be run from the client. If you want the dialog to be shown onclick of the button, you must send the element before it's clicked, at the moment when it is sent to the client. You should have the dialog element hidden until the user clicks the button. It could be something like:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="Lib\JqueryUIcss.css">
<script src="Lib\Jquerylib.js"></script>
<script src="Lib\JqueryUI.js"></script>
</head>
<body>
<button type=" button" class="LeButton" onclick="$('#dialog').dialog()"> Clicky Clicky!</button>
<div id="dialog" title="Basic dialog" style="display:none">
<p>Image:</p>
</div>
</body>
</html>
You could also change the onclick attribute to a script in the head like this:
<script>
$(function() {
$(".LeButton").click(function() {
$('#dialog').dialog();
});
});
</script>
I recommend you to change the class of the button for an id, and then using #LeButton instead of .LeButton
You can handle this on the client-side without the need to use PHP to do so you need to give your button a unique identifier so whenever the button is clicked you can open the dialog using a simple evenlisener like so:
var dialog = $( "#dialog-form" ).dialog({
autoOpen: false,
height: 400,
width: 350,
modal: true,
close: function() {
// do stuff here whenever you close your dialog
}
});
document.getElementById('my-button').addEventListener('click', function () {
dialog.dialog('open');
});
#dialog-form {
background-color: #ccc;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script>
<button type=" button" id="my-button" class="LeButton"> Clicky Clicky!</button>
<div id="dialog-form">
Name: <input><br/>
Password: <input type="passowrd">
</div>
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="Lib\JqueryUIcss.css">
<script src="Lib\Jquerylib.js"></script>
<script src="Lib\JqueryUI.js"></script>
</head>
<body>
<form action="index.php" method="POST" enctype="multipart/form-data">
<input type="hidden" name="LeButton" value="an_arbitraty_value">
<input type="submit" class="LeButton">
</form>
<?php
if(isset($_POST['LeButton'])){
echo'<div id="dialog" title="Basic dialog">';
echo'<p>Image:</p></div>';
}
?>
</body>
</html>
When you load the html page $_POST['LeButton'] is not set. Therefore the intended dialog box wil not be generated in the page. In order to have $_POST['LeButton'] set, you should pass it to the html page first, hence the form I added.
Alternatively you could go for a full javascript solution like so:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="https://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<style>
.hidden { display: none }
</style>
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<button type=" button" class="LeButton" onclick="showDialog();">
Clicky Clicky!
</button>
<div id="dialog" title="Basic dialog" class="hidden">
<p>
This is the default dialog which is useful for displaying information.
The dialog window can be moved, resized and closed with the 'x' icon.
</p>
</div>
<script>
function showDialog() {
$( "#dialog" ).dialog();
};
</script>
</body>
</html>
Yes, i know this is a duplicate, but all the answers i've read didn't help me, i have a side by side working example, from w3school, it works, and mine doesn't, what i am trying to do is show a tooltip warning the user to use numbers only, but instead, it just refreshes the page.
This is my full html page code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Test</title>
<link rel="stylesheet" media="screen" href="Css/style.css"> /*---not using the bootstrap css because it messes up the form layout, so i copied every tooltip referenced block to my style.css instead.---*/
<script type="text/javascript" src="js/tooltip.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
var previous;
$(document).ready(function(){
$('.btn').tooltip();
});
//Buy Button JS code
$(function () {
$("#searchform").bind('submit', function () {
var str = $('#search-form').val();
if (str.match(/^[0-9]*$/)) {
$('#search-form').tooltip({title="You did good :)"});
}
else
{
$('#search-form').tooltip({title="Please enter numbers ONLY !"});
}
});
});
</script>
</head>
<body>
<div class="box">
<form class="search-form" method="post" id="searchform">
<input type="text" id="search-form" name="textbox" placeholder="Please enter your code" required/>
<button type="submit" name="submit" class="btntxt">Validate</button>
<div id="search_results"></div>
</form>
</div>
</body>
</html>
I didn't put the data-toggle:"tooltip" neither a title:"sometitlehere" in the element's options, because i don't really need it.
There are few mistakes in your code,
//it should be title: and not title=
$('#search-form').tooltip({title:"You did good :)"});
The above line initializes the tooltip once your code excutes.
After that if the tooltip title is updated, the tooltip is needed to be destroyed and re-initialized with new title.
var previous;
//Buy Button JS code
$(function () {
$("#searchform").bind('submit', function () {
var newTooltip="";
var str = $('#search-form').val();
if (str.match(/^[0-9]*$/)) {
newTooltip = "You did good :)";
}
else
{
newTooltip = 'Please enter numbers ONLY !';
}
$('#search-form').attr('title', newTooltip).tooltip('fixTitle').tooltip('setContent').tooltip('show');
setTimeout(function(){
$('#search-form').tooltip('hide').tooltip('destroy');
}, 1500);
});
});
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
/*---not using the bootstrap css because it messes up the form layout, so i copied every tooltip referenced block to my style.css instead.---*/
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<div class="box">
<form class="search-form" method="post" id="searchform">
<input type="text" id="search-form" name="textbox" placeholder="Please enter your code" required/>
<button type="submit" name="submit" class="btntxt">Validate</button>
<div id="search_results"></div>
</form>
</div>
You are using form so you need to return true or false on validate action so your code should be like
if (str.match(/^[0-9]*$/)) {
$('#search-form').tooltip({title="You did good :)"});
return true;
}
else
{
$('#search-form').tooltip({title="Please enter numbers ONLY !"});
return false;
}
are you initialising the tooltip in the js? - tooltips won't show unless you have this in the code:
$(function(){
$("[data-toggle=tooltip]").tooltip();
})
ok - I just looked at your code - you have :
$('.btn').tooltip();
listed in theree, but your button has the class "btntxt" and you are also trying to get a tooltip on the search form - but that has the id of "search-form" - neither of which will be affected by your tooltip declaration. Best to use the one I gave in the is post so that all elements with tooltips can display them. Setting them to individual classes or ids is too restrictive if you forget that your class or id is not the same as the one listed in the js.
you have this order to your scripts:
<script type="text/javascript" src="js/tooltip.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
Does the tooltip.js require jquery? - if so you may need to invert that order
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="js/tooltip.js"></script>
I have a single page site:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7.5/leaflet.css" />
<link type="text/css" rel="stylesheet" href="stylesheet.css" />
<script src="http://cdn.leafletjs.com/leaflet-0.7.5/leaflet.js"></script>
</head>
<body>
<h1>Hello World</h1>
<p>I'm hosted with GitHub Pages.</p>
<div id="map"></div>
<FORM>
<INPUT id="but" Type="BUTTON" Value="About Me" />
</FORM>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src=script.js></script>
</body>
</html>
And I would like to add some handler to button #but, and try to use with script in script.js:
var mapClicked = function() {
alert("Map!");
// create a map in the "map" div, set the view to a given place and zoom
//var map = L.map('map').setView([55.432, 37.654], 13);
}
$(document).ready(function() {
$('#but').click(mapClicked());
});
But then I run this html in browser and click to button, nothing happens.
By adding () to the function name when referencing the function by it's name. This will call the function directly and the returned value will be assigned as callback of the click event. By removing () of the function name(or rather function call), the function is referenced correctly and called when the click event occurs on the element.
Change
$('#but').click(mapClicked());
to
$('#but').click(mapClicked); // <----- Removed ()
On clicking the radio button nothing happens, why?
<html>
<head>
<link type="text/css" rel="stylesheet" href="css/bootstrap.css" />
<script type="text/javascript" src="jquery.js">
$("input[name='check1']",$('#Search_By')).change(function()
{
alert('yo');
});
</script>
</head>
<body class="well">
<form action="/abc/readservlet" method="post">
<div class="well" id="Search_By">
<h3><b/>Search BY</h3>
<input type="Radio" name="check1" value="Search BY Key"> Key<br/><br/>
<input type="Radio" name="check1" value="Search By Tablename"> Tab_name
<br/>
</div>
On clicking radio button nothing happens...
If your <script> tag has a src attribute, its contents will be ignored, so your code isn't going to actually run at all.
You need to put your code into a separate script tag and run the code when the document is ready:
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#Search_By input[name='check1']")).change(function() {
alert('yo');
});
});
</script>
Or put both of those script tags at the very bottom of the <body> tag.
The javascript code to create the onchange handler should be as follows. Try it out.
...
$("#Search_By input[name='check1']").change(
function()
{
alert('yo');
});
...
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>
