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 am working on automating a site and in console. When I am using
jQuery methods to change value of dropdown (hidden/generated values) it works perfectly fine, correctly mimics human behavior.
But when I am using JavaScript it's changing the value, but the next dropdown doesn't get activated.
The code I am using:
jQuery
$("#carMakeInput").val("BMW").change()
JavaScript
document.getElementById("carMakeInput").value = "BMW";
document.getElementById("carMakeInput").dispatchEvent(new Event("change"));
Does jQuery do something extra?
I made a little snippet to test what you were saying. In my snippet, JS is activating and jquery not (I confirmed by commenting out the lines that fire the change event). So I think it's a question of how you add the listener
document.getElementById("carMakeInput").addEventListener("change", function() {console.log("changed");});
$("#carMakeInput").val("BMW").change()
document.getElementById("carMakeInput").value = "BMW";
document.getElementById("carMakeInput").dispatchEvent(new Event("change"));
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id="carMakeInput" />
It works fine in IE but does nothing in FF.
Here's the code I'm using it with.
The code does a some things for proboards.com.
I think the explanation of the code is irrelevant in this case. If not, let me know.
But the focus part is simply to put focus on a single element.
Here's the code:
<script>
var TitleBarGuestMessage="Hello Guest!";
var TitleBarMemberMessage="Welcome Back "+pb_displayname+"!";
var i,table,LTPI,LTPItable,titlerow,titlerowcell1,LTPIrow,LTPIrowcell1,shortcutA,shortcutB,shortcutC,
td=document.getElementsByTagName("td");LTPItable= document.getElementById("rectangle_table");LTPI=document.getElementById("rectangle_right_side");LTPItable.style.width="100%";
shortcutA=LTPI.parentNode.parentNode.parentNode.parentNode.parentNode.parentNode;
shortcutB=shortcutA.previousSibling.parentNode.parentNode.parentNode.parentNode.parentNode.parentNode;shortcutC=shortcutA.firstChild;
shortcutA.previousSibling.parentNode.parentNode.cellSpacing="0";
shortcutA.previousSibling.style.display="none";
shortcutB.className="";
shortcutB.bgColor="transparent";
shortcutC.align="center";
shortcutC.style.backgroundColor="transparent";
shortcutC.className="";
LTPI.style.display="none";
for(i=0;i<td.length;i++){
if(td[i].className=="titlebg" && td[i].colSpan=="2"){
td[i].parentNode.parentNode.parentNode.id="forum";}}
table=document.getElementById("forum");
if(pb_action=="home"){
setTimeout(function(){table.focus();}, 2000)};
titlerow=table.insertRow(0);
titlerowcell1=titlerow.insertCell(0);
titlerowcell1.className="titlebg";
titlerowcell1.colSpan="5";
titlerowcell1.id="LTPI_titlebar";
LTPIrow=table.insertRow(1);
LTPIrowcell1=LTPIrow.insertCell(0);
LTPIrowcell1.colSpan="5";
LTPIrowcell1.innerHTML=LTPI.innerHTML;
LTPIrowcell1.id="LTPI_row";
if(pb_username=="Guest"){
titlerowcell1.innerHTML=TitleBarGuestMessage}
else{titlerowcell1.innerHTML=TitleBarMemberMessage}
</script>
This is the focus part of the script:
if(pb_action=="home"){
setTimeout(function(){table.focus();}, 2000)};
I have also tried:
setTimeout("table.focus();",2000);
Any suggestions?
this is because DOM table element does not have focus method (although it is implemented in IE). I assume that you need to scroll to that element, so you can do it this way:
window.scrollTo(0,table.scrollHeight);
Or as in your exact code:
if(pb_action=="home"){
setTimeout(function(){window.scrollTo(0,table.scrollHeight)}, 2000)};
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.
I have written one custom paremeterized jquery function for fadein and fade out. That function works fine in IE but not in firefox.
The function is :
jQuery.fn.dcFadeIn = function(newDiv) {
var openDiv = newDiv;
return $(openDiv).fadeIn();
};
<input type="radio" name="doc3" value="independentCall" class="radioButton" id="indMetaCalls1" onClick="jQuery.fn.dcFadeIn(indCallDetailsDoc1);" />
You are refereing to an element as if it is a member of the windows object. Only IE puts elements in the windows object, so that doesn't work in any other browser.
Use the JQuery object to get a reference to the element:
onClick="jQuery.fn.dcFadeIn($('#indCallDetailsDoc1'));"
Do you have javascript enabled in FireFox?
If so, can you show the markup for 'indCallDetailsDoc1'?
Also, why don't you use 'newDiv' directly, instead of copying it into 'openDiv' first?
Try Changeing:
onClick="jQuery.fn.dcFadeIn(indCallDetailsDoc1);"
to:
onClick="jQuery.fn.dcFadeIn(this);"
What is "indCallDetailsDoc1" and why do you call functions using jQuery.fn.dcFadeIn()? You cannot call plugin functions like this.

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
Edited : 26.08.2009
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.
