I'm doing the following things:
1) A user clicks on a page and it opens up a pop-up.
2) In the pop-up I try to set a text box in the parent page.
The problem is that the code works in IE, but does not work in Fire Fox. I am testing with FF 3.6.13. I'm assuming it has to do something with the window.opener.document.getElementById or self.opener.document.getElementById. I tried both lines they don't work in FF.
function passValues(comment_text_box_id)
{
var checkbox_values = "";
for(i=0; i<document.form1.elements.length; i++)
{
if(document.form1.elements[i].type=="checkbox")
{
if(document.form1.elements[i].checked == true)
{
if(checkbox_values == ""){
checkbox_values = document.form1.elements[i].value;
}
else{
checkbox_values = checkbox_values + "," + document.form1.elements[i].value;
}
}
}
}
//window.opener.document.getElementById(comment_text_box_id).innerText = window.opener.document.getElementById(comment_text_box_id).innerText + checkbox_values;
self.opener.document.getElementById(comment_text_box_id).innerText = self.opener.document.getElementById(comment_text_box_id).innerText + checkbox_values;
}
innerText is only supported by MSIE. In other browsers create a TextNode containing the given text and insert the TextNode into the target-element.
Replace the last line with:
self.opener.document.getElementById(comment_text_box_id)
.appendChild(self.opener.document.createTextNode(checkbox_values));
(or use innerHTML if the text doesn't contain html-markup)
edit:
Replace the word ajax with Javascript Framework.. Jquery, Mootools, Etc...
Why not use ajax and create a modal html "popup" that way you remain in the context of the parent page at all times, and you can modify your "parent" page based on what the xmlHttpRequest Object returns. It stand to benefit using this technique since it will keep your page from being blocked by a popup blocker.
Here is a link I found when I searched for modal html dialog box http://www.dhtmlgoodies.com/scripts/modal-message/demo-modal-message.html

I'll start by apologising as this may seem like or actually be a duplicate, but I've tried every solution I've encountered and none seem to be working for me.
In my HTML I have an iframe referencing another HTML document. With JavaScript, at the press of a list of buttons I insert text into the body of that iframe. I also use JavaScript to maintain focus on the iframe body. The problem is that nothing appears to work for me to get the cursor to move to the end of the text each time I press those buttons, it always moves to the beginning.
One of the solutions I've tried was to add this code to the function that handles my button presses:
iFrameBody.focus();
var content = iFrameBody.innerHTML;
iFrameBody.innerHTML = content;
so the function looks like this:
function typeIn(buttonId) {
var iFrameBody = document.getElementById("iFrame").contentWindow.document.body;
iFrameBody.innerHTML += buttonId;
iFrameBody.focus();
var content = iFrameBody.innerHTML;
iFrameBody.innerHTML = content;
}
Something else I tried was, in the HTML file referenced by my iframe I did:
<body onfocus="this.innerHTML = this.innerHTML;"></body>
I tried several other more complicated solutions that frankly I didn't even quite understand to be honest, all to no avail. Any help would be much appreciated.
I figured it out. The issue was that I was using a body element, writing to it's innerHTML and trying to set focus on the body. By simply using a textarea inside my iFrame instead it became very simple and it only required the simplest code.
This to set focus when the page loads:
window.onload = function () {
var iFrameTextArea = document.getElementById("iFrame").contentWindow.document.getElementById("iFrameTextArea");
iFrameTextArea.focus();
}
And then this to set the button to write to the textarea while maintaining focus:
function typeIn(buttonId) {
var iFrameTextArea = document.getElementById("iFrame").contentWindow.document.getElementById("iFrameInput");
iFrameTextArea.focus();
iFrameTextArea.value += buttonId;
}
Super easy!!
Instead of again using textarea in iframe, u can also solve this by using the following code.
var iframeElement = document.getElementById("iFrame").contentWindow.document.body;
iframeElement.focus();
var len = iframeElement.length ;
iframeElement.setSelectionRange(len, len);
I have a small site with a script that runs a query with mysql and returns me some data, including domains. These domains are generated html links and I want to change in javascript, since I can not access the part of php, but yes to the javascript and css code.
I just want you the code is run when the click event is triggered on a link. I tried to stop the execution by default and make a change, but my code does not open the page. If I remove preventDefault only works in firefox, but I have not chrome. (window.open not use, I want to change the original link).
var domains = document.getElementsByClassName("domain");
for(var x = 0; x < domains.length; x++){
if(domains[x].addEventListener) {
domains[x].addEventListener("click", changeLink, "false");
} else if(domains[x].attachEvent) {
domains[x].attachEvent("onclick", changeLink);
}
}
function changeLink(evt){
var urlOriginal = this.href;
// If I remove preventDefault, the function runs correctly on firefox but not in chrome
evt.preventDefault();
if(urlOriginal != 'http://google.com') {
urlOriginal = urlOriginal.replace(/http:\/\//g, '');
evt.stopPropagation();
this.href = 'http://intodns.com/' + urlOriginal;
console.log('Okay !');
}
return true;
}
I tried several changes but none is running, not really the case.
Does anyone know the cause of malfunction? How I can fix it without window.open?
Thanks
try stopPropagation instead
http://api.jquery.com/event.stoppropagation/ - read more about it
If I understand correctly, you want to redirect the user to a different link, instead of the one that is set in the href attribute.
Once the click is made, nothing will happen if you change the href attribute of the element. What you are looking for is redirecting the user, and this is made possible by modifying the location object which resides on window.
Instead of this line:
this.href = 'http://intodns.com/' + urlOriginal;
Try this:
window.location = 'http://intodns.com/' + urlOriginal;
Just like the question says, I'm trying to clear a form from a modal window while the modal stays up. I've tried:
if (myDocument.title == "Modal Window") {
parent.document.getElementById("textbox")
}
(I need it to do more than 1 tb, but used that just to try to get there. No luck.
It is contained within an iFrame, so I tried:
if (myDocument.title == "Modal Window") {
var ifr = document.getElementById("iFrame")
var form = ifr.document.getElementById("form")
ClearForm(form)
}
The ClearForm(form) function I stole from another Stack Overflow answer:
function ClearForm(form) {
$(':input', form).each(function () {
var type = this.type;
var id = this.id;
if (type == 'text' && id != 'text2')
this.value = "";
});
}
That 'text2' is one specific tb that we need to remain populated.
Any idea what I'm missing? I've been plagued with this bug for weeks.
I expect your issue is that the form is within an iFrame - most browsers won't allow you to modify elements within an iFrame, from the parent page, if they aren't from the same origin (or if the server is set up to deny it, or if you're looking at the page locally... see here for more details)
To double-check, try moving the form markup into the same page as the modal is in and run your function ClearFormfrom there. I expect that you'll then find it works.
Your only way around this would be to include the ClearForm function within the iFrame'd page, and then trigger it from the parent.
I'm trying to use Javascript to replace the selected text in an arbitrary selected TEXTAREA node in Chrome (! not a content editable div !) The code fragment I see repeated in lots of places to replace selected text basically does this:
var sel = window.getSelection();
var range = sel.getRangeAt(0);
range.insertNode( document.createTextNode("test "));
However, this does not work for input fields such as TEXTAREA or INPUT TYPE=TEXT. The text is inserted BEFORE the TEXTAREA instead of inside it.
There is an alternative method to modify the selection text inside a text area using textarea.selectionStart and textarea.selectionEnd. However, these require figuring out which textarea element is actually active/selected. Chrome/Webkit document.activeElement seems to be broken and has been broken for a long time. I can't figure out any workaround to find the "currently selected textarea". See the bug here...

You can see a micro-demo of the problem I'm trying to solve here.

http://ajaxandxml.blogspot.com/2007/11/emulating-activeelement-property-with.html
Any thoughts on this?
Given a webpage with an arbitrary bit of text selected in an arbitrary TEXTAREA node, without knowing ahead of time what textarea the focus is in, how do I find the active textarea and replace the selected text with some other text?
(( FYI: I'm using this code in a Chrome extension. An in-page javascript content script is extending the page javascript, so I have no idea what the page structure is ahead of time. It needs to work for any webpage. ))
I think the problem you may be having is that the active element changes as a result of clicking the button before your code runs. If you instead use the mousedown event and prevent the default button action, it works fine in Chrome:
http://jsfiddle.net/b3Fk5/2/
It appears that as of 8/23/2012, Chrome does not properly support activeElement, as it is often set to "body" when it shouldn't be.
There may also be some challenges because in my chrome extension, right-clicking to get a context menu might be altering the activeElement.
The solution was to provide a focus handler to create a more reliable activeElement in Chrome, and then use direct interaction with the TEXTAREA to handle the selection replacement.
var dActiveElement = null;
function _dom_trackActiveElement(evt) {
if (evt && evt.target) {
dActiveElement = evt.target;
console.log("focus on: " + dActiveElement.nodeName +
" id: " + dActiveElement.id);
} else {
console.log("focus else..");
}
}
if (document.addEventListener) {
document.addEventListener("focus",_dom_trackActiveElement,true);
}
function insertTextAtCursor(text) {
console.log("insertTextAtCursor : " + text);
if (dActiveElement.nodeName.toUpperCase() == "TEXTAREA") {
console.log("selection in textarea! id: " + dActiveElement.id);
var ta = dActiveElement;
var saveSelectionStart = ta.selectionStart;
var newvalue = ta.value.slice(0,ta.selectionStart) +
text + ta.value.slice(ta.selectionEnd,ta.length);
console.log("output : " + newvalue + ", len : " + newvalue.length);
var newSelectionEnd = ta.selectionStart + text.length;
ta.value = newvalue;
ta.selectionStart = ta.selectionEnd = (newSelectionEnd);
}
}
I am using zeroclipboard to add a "copy" link to each row in a fairly large list, within a user script. To accomplish that, I using a method similar to the one listed on this page, where the ZeroClipboard.Client() element for each row is created when the user mouses over the row. This is working great in FireFox, but not in Chrome.
Also as a note: I copied the contents of the ZeroClipboard.js file into the user script itself instead of including it in an external file.
Here is the markup that creates the copy button for each element
<span style="color:blue; text-decoration:underline; cursor:pointer" id="copy_'+id+'" class="CopyLink" link="'+url+'" onmouseover="clipboard.add(this)">Copy</span>
Here is the code segment that adds the clipboard's client object:
function main(){
window.clipboard = {
load: function (){
if(!clipboard.initialized){
ZeroClipboard.setMoviePath("http://www.swfcabin.com/swf-files/1343927328.swf");
clipboard.initialized=true;
console.log("Clipboard intialized");
}
},
add: function(element){
clipboard.load();
var clip = new ZeroClipboard.Client();
console.log('Clipboard client loaded: ' + element.id);
clip.glue(element, element.parentNode);
console.log('Clipboard glued: ' + element.id);
clip.setText(element.getAttribute('link'));
console.log('Clipboard text set: ' + element.getAttribute('link'));
clip.addEventListener('complete',function(client,text) {
console.log('Clipboard copied: ' + text);//doesn't fire in chrome
});
clip.addEventListener('load',function(client) {
console.log('Clipboard loaded: ' + element.getAttribute('link'));
});
}
}
//other code in user script including injecting above markup
//as well as contents of ZeroClipboard.js
window.ZeroClipboard = { ... }
}
var script = document.createElement("script");
script.appendChild(document.createTextNode('('+main+')()'));
(document.head || document.body || document.documentElement).appendChild(script);
In this block, every console.log fires in FireFox when I mouse over and click the copy span, but in chrome, all except the 'complete' listener fire. I was able to verify that ZeroClipboard is working in my Chrome by using the example on this page. I am also able to verify that the flash object is being added to the page in the correct location, but it is simply not responding to a click.
Since the zeroclipboard code is no longer being maintained according to the site, I'm hoping someone out there can help me out. I'm thinking there is possibly some issue with dynamically adding the embedded flash objects in chrome on mouseover, or perhaps some difference between user scripts in chrome vs firefox with greasemonkey? Any help would be greatly appreciated, thanks
I'm not sure the reason behind it but I have been running into this on Chrome as well. I had two zeroclipboard implementations, one that was visible on page load, and one that was only visible when the user opened a dialog. The one that was visible on page load worked as expected, but the other one didn't. In order to "solve" the issue, I had to render the zeroclipboard link, set its absolute position to be off the screen (-500 px), then add some javascript to move the link into place when the dialog opens. This is an ugly solution but I think is the only way to get it to work in Chrome. Your case is particularly hairy since you have lots of dynamic zeroclipboards on your page whereas I only had one, but it seems to me that there's no reason this won't work for you.
