I'm using javacsript functions onclick and onblur on text area they are working fine in Firefox but never work in IE8. I need to call javascript function to be called on every key press.
What is the solution?
<textarea name="txtClassifiedText" rows="5" cols="40" id="txtClassifiedText" onblur="recalc()" onkeypress="recalc()" onclick="this.value='';">Enter your classified text here (MAX 40 words)*</textarea>
<script>function recalc() {
alert('hi');
}</script>
There's no javascript error in IE8 or FF
I believe "recalc" might be a protected word. Rename your function something like "booger" and retest. Good luck!
See here: http://msdn.microsoft.com/en-us/library/ms537634(v=vs.85).aspx
The recalc method allows authors to explicitly cause the values of dynamic properties to be updated.

So I have a very simple JS function written that works like the following.
There is a button that has the following code:
<button type="submit" class="large button" onclick="addCart(76,95,73,96);">
<i class="icon-shopping-cart"></i> Add to Cart
</button>
Now when that is clicked there is a very simple function added to the page below that looks like the following:
<script type="text/javascript">
function addCart(pid, pattr, pval, pscent = 0) {
...
}
</script>
This works perfectly in Chrome, Firefox, Chrome for Mobile, Safari for Mobile.
But this does not seem to work on Safari on Mac. Instead I get the following error:
ReferenceError: Can't find variable: addCart
I cannot figure out why. It's hard for me to add a listener because there are 7 buttons and a wide arrange of variables that are being sent, and I'd rather send that like I'm currently doing.
I finally found the issue.
The function was creating an error in Safari so it was never being defined. I changed the function to the following:
function addCart(pid, pattr, pval, pscent) {
pscent = (typeof pscent !== 'undefined') ? pscent : 0;
...
}
Notice the big difference is that I was no longer using the Function to declare a default value for 'pscent' and instead I do it the old school method. Not sure if this is being caused by an older version of Safari or what.
If you are here because of a similar error, look for some potential JS error in the function which will prevent the function from being declared.
Looks like you are submitting a form since the input type is "submit". Have you tried testing it with the input type set to "button"?
if you are using jquery try to use document ready function
$(document).ready(function() {
// code here
});
or use plain javascript self executing function here
(function() {
// your page initialization code here
// the DOM will be available here
})();
the possible reason is your function is not available at the time of click
Here is a sample (using jquery) https://jsfiddle.net/baphmoLt/
My friends, the code below used to work in Chrome till version 52.x but in the newest version it does not work anymore. Does any of you have any idea why it does not work?
https://jsfiddle.net/2jtrs2m2/
<input type="text" id="test" />
<script type="text/javascript">
var my_event = document.createEvent("TextEvent");
my_event.initTextEvent("textInput",true,false,window,"T");
document.getElementById("test").focus();
document.getElementById("test").dispatchEvent(my_event);
</script>
Usually when I executed this code, Chrome would insert the character T in the input. I dont want to use document.getElementById("xxx").value = "T" cause in some very specific cases I am working on, I really can only use the code above firing the oninput event which for some reason is not working anymore.
Try using document.execCommand
ie;
document.execCommand("insertText", false, "foo");
I have a very simple piece of javascript code that just should work and it only works when I run it in the browser console:
<script>
$(".hopscotch-close").click(function () {
alert("Hi");
Cookies.set("tourState", "closed")
})
</script>
Because it runs in the console I know that:
1) the ".hopscotch-close" is OK;
2) there are no errors in the code that could prevent it from running;
Also:
1) because is a "click" event I know that I haven't got a problem with the DOM being ready (and I can put everywhere - but in this case in at the bottom of the <body>;
2) I know I don't have an issue because of using the same name for a class than something else that exist;
3) The behavior is the same in Safari and Firefox, so its not a Browser issue.
I know this is tough without the full code, but if someone has experienced this maybe has na idea about what could be the problem.
From your comments I sense that the element is getting appended dynamically so instead of
$(".hopscotch-close").on('click',
you need to make use of event-delegation as
$(document).on('click','.hopscotch-close',function(){
That will do the trick.
If you are appending .hopscotch-close to any already existing static
element then instead of $(document).on('click' you can use
$('#yourStaticElementId').on('click','.hopscotch-close',function(){
which improves site performance.
I need to save the content of the textarea. I tried onkeyup, it is working properly but it is very heavy and some performance issue and onchange and onpropertychange is not working for me. Can anyone suggest some alternative.
function setMsgSession(){
var newMsg = $('#newComposeMessage').val();
alert(newMsg);
}
<h:inputTextarea id="newComposeMessage" pt:placeholder="Message" pt:maxlength="29000" rows="10" queryDelay="750" minQueryLength="4" onpropertychange="setMsgSession()" >
I am developing webapp using jQuery.
I have functionality that adds new row of 3 input fields. After creating these DOM elements I want to focus one of input fields. I am doing it with calling jQuery focus() function on necessary input field.
Problem is that calling focus() works fine in IE6 and FF3.5, but not working in IE8.
I was trying to make simple working example of this problem for showing it here, but with stripped version of code focus() is working fine. So my guess was that DOM is not ready yet when I call focus() in IE8. For this I tried calling setTimeout('myFocus()',400). I had success and in some of cases focus was really working but still not always. Randomly it does not focus my input field.
Question is: Has anybody faced similar problems and does anybody have any idea how to workaround it? Using setTimeout feels like very ugly workaround.
Tnx in advance

Succeeded to reproduce on simple example. Here is HTML+JS code that reproduces this bug on IE8.
<html>
<head>
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
function performChanged() {
formChanged = true;
}
function handleChange() {
var parentDiv = $('#container');
newValue = $(html).html();
parentDiv.html(newValue);
$(".sel1",parentDiv).bind('change',handleChange);
//alert('Uncomment this and after alert focus will be on input');
$("input.cv_values",parentDiv).focus();
}
$(document).ready(function() {
$('.trackChange').bind('change', handleChange);
});
var html = '<div class=\"div1\">\n<select class=\"sel1\" id=\"sel1\" name=\"sel1\"><option value=\"\"><\/option>\n<option value=\"11\">Select me to see problem<\/option>\n<\/select>\n\n\n<input class=\"cv_values\" id=\"sel3\" name=\"sel3\" size=\"30\" type=\"text\" value=\"\" /><br/>Focus should in input field. With alert it is but without alert focus is not there</div>';
</script>
</head>
<body>
<select class="trackChange" onchange='performChanged();'>
<option value=""></option>
<option value="1" >Select me to generate new inputs</option>
</select>
<div id="container"></div>
</body>
To reproduce:
1) select value from first dropdown. You will see that first time input is working
2) select value from second dropdown. You will see that bug is reproduced.
Then in code you can comment out line where it shows JS alert(). Strange thing is that if there is this alert() then after it focus is working fine.
Hope this helps to understand where my problem is.
P.S. I need my app to work this way - it is regenerating those inputs after selecting value from dropdown. This is simplified example of my app ;).
I had a similar problem with my app, but I can't reproduce the focus problem with your code. My problem was slightly different in that my page had a link hash that made IE not give my element focus.
Anyway, to get around the problem I added a timeout:
setTimeout(function () {
$('.my-thing').focus();
}, 100);
Not noticeable by a user but it gives IE a moment to breathe.
In conjunction with Kazys's solution, I found this to fix all my problems (using IE8 & .HTA files):
$("elem").blur();
$("elem").focus().focus();
I have no idea why, but somehow calling focus twice helps IE along.
EDIT:
I have found that calling .show() and .select() can also help.
Strangely i had the same problem and resolved it using plain old javascript like so:
document.getElementById('friend_name').focus();
Using jQuery equivalent $('#friend_name').focus(); didn't work in IE8 :-/
Had similar problem with IE8. I wanted to focus input in dialog when it is opened. Used autoOpen = false. Noticed that focus doesn't work only for first focusable element in dialog. Tried setTimeout but it worked only sometimes. Blurring element before focusing helped me.
$('#dialog').find('#name').blur();
$('#dialog').find('#name').focus();
Since you have not posted any code are you using:
$(document).ready(function(){
//code here
});
This will make javascript run after the html is loaded.
And you should use live events also. When your adding inputs to the dom the will automatically have focus binded to them.
$("p").live("focus", function(){
alert( $(this).text() );
});
This means that every p that is created will have a focus binded to it.
This is the best solution for the moment to set focus:
$('.elt').fadeIn(200, function() {$('.elt').focus();});
This is an old question, but it is top in search, so wanted to update.
I don't know if there was ever a time that it was fixed, but I ran into this issue again today in IE11, using jquery-2.1.3. I found that wrapping the focus call in a setTimeout, as set out by Ponny above, worked best for me.
I did need to increase the timeout in some cases, to get it to work.
