JavaScript - Moving The Cursor/carat To End Of Text In Editable Iframe?
Hi all,
I'm trying to get the cursor position to move to the end of the text within an editable iframe or div. I've been pointed to something called TextRange and have been reading up on it for days yet couldnt make sense of much (i'm still very new). what i'm trying to do is on a button click, the cursor will move to the end of the text in the iframe. any help or pointers would be greatly appreciated. thanks. Similar TutorialsDo you guys have any idea how I could move a div around a page on mouse down? Like drag and drop it where I want it to be on the page and grab its x,y position? If you guys have any code snippets or tips that would be greatly appreciated thanks! Please could someone tell me the JavaScript to allow the user to edit the content in an iframe, but I need to know if it will allow the user to edit the iframe in all browser types.
Hello all, I am using an editable iframe to change the style of the text as a person enters text depending on what they type in. Sometimes the text needs to be a link, and while inserting a link works, I can't click on it. I was wondering if anyone knows how to get links in an editable iframe to click through. I've researched this for a while now without getting anywhere. Right now I'm guessing that I need to somehow find out if the user is hovering over a link and turn "designMode" off for that section of text, or the whole iframe, I'm not completely sure. Anyway, any help would be greatly appreciated! How do I get the pixel position of the caret in an editable IFrame? I am building a WYSIWYG editor which works for Gecko, Trident, Webkit and Presto. I am doing this by setting the designMode to 'on' for an IFrame. The problem that I am having is that I need to know the pixel position of the caret so I can determine if the caret is at the bottom of the page. The reason I want the pixel position is so that way I can auto scroll the scrollbar to that position. I should mention that we are using JavaScript. Any ideas appreciated. Hello I have several issues with my multilevel drop down menu The First issue is : the page has 2 iframes (one has the horizontal multilevel drop down menu on the top) the below iframe has my site address Now, when i hover over the menu it does not open or expand but when i open just the menu without any iframes it does This clearly means that the menu is not coming out of the iframe Please help me bring it on top of everything of the page Note: i have placed the menu in one iframe and a page opens below it in another iframe. The Second issue is : I want the navigation bar that is the multilevel drop down menu to be editable Which means i have a blog and a forum on my site but my visitor wants that the blog should not appear there and another link to play games should be there and hence he/she can edit it And please also try to make it work on cookies so that the user info and preferences are saved in cookies and whenever he/she comes back they see the page their way. For you: I would like to tell you that IdeaLab has launched a Twitter Advertising, Widget and Search platform and the first 1000 people are getting $100 go to tweetup.com Please help me, it will be really appreciable. Thank you very much in advance! hi, i need to be able to allow a user to past into an editable div (via whatever the user chooses: right-click and paste, shortcut key, etc), but i want to discard formatting and only take the plain text. i can't use a textarea since the div will allow basic formatting (bold and italic) if applied by user-initiated events. the onbeforepaste event looked promising, but according to quirksmode the support is so limited as to be unusable. i searched the board, so apologies if this has been asked and answered. tyia for any suggestions. I have 2 questions. Can I have draggable editable images? I can make my images movable around the page, but I would like to be able to make the images editable and have the text follow the images. I would like to either have a drop down menu or buttons that can make the images displayed on the page then edit them and move them to my map location on the page. Is this possible, and thanks for any help guys. Here is the code I used for the movable images. Code: <img src="images/loconorth.gif" class="dragableElement" style="float:left"> <img src="images/locosouth.gif" class="dragableElement" style="float:left"> <img src="images/Loco east.png" width="80" height="36" class="dragableElement" style="float:right"> <p> <p><img src="images/Loco west.png" width="80" height="36" class="dragableElement" style="float:left"> I have a paragraph of text which is embedded in an IFrame. when i search particular string in that paragraph, if the string is found then the string will be highlighted and the full paragraph is loaded in IFrame. but, if the searched text is at the bottom, then scroll bar in an iframe is not automatically moved to the hidden highlighted text position. any body help me to move the scroll bar automatically to the hidden text position in the IFrame? please run the code, type any text from the paragraph of text and click serach button. see the output.

I've a div that is editable (contentEditable = true). The div has a fixed size like a letter page. When the user has written so much text that the text overflows I want add a new div above and let flow the overflown text in the other div. (it's the some behavior like MS Word in page view, but now it is in the web) It is possible to do something like this in the web? One way to implement this is to check if the text of the div overflows (I've found java script examples in the web which do that). And than I need the text that overflows to move it to the next div. But I have not found a function that do this. Is there such a function? Another way is to insert a gap at that position a new page begins and use an background image that looks like a page border. With this solution, the whole text is in one div but it looks like floating to another page. But therefore, I have to add a gap between to lines at a specific position (the page border/margin and the gab between the pages). Does anyone have an idea how to realize this? Maybe there are other possibilities to find a solution, aren't there? I hope, you have understand what I want to realize. If not, please feel free to ask me! Thank you for answers and hint in advanced! Konstantin I'm trying to write a function that is similar to the ctrl+f functionality you get in IE, where you have a search string and when you click 'next' the whole string if matched is highlighted by the cursor. This works fine for inputs and text areas using the following code: Code: function setCaretPos(obj, start, end)
{
var range = obj.createTextRange();
range.moveStart('character', start);
range.moveEnd('character', end - obj.value.length);
range.select();
}
But now I need to get it to work for normal text in a text node that is in the HTML/DOM. Is there an equivalent way of making the above method work for text in text nodes? Alternatively is there a way to make the browser (IE) at least focus on some text in a text node? (I could then highlight it with CSS styles). Sup yo, I need to add text in a <textarea>, but i can only append text at the end. Is there any way to add text to where the cursor is currently at? Code: function addCharm(var1) {
var newtext = var1;
document.lolform.inputtext.value += newtext;
}
And below i has sum buttonz that uses that function. So, again, how can I add text to where the I-beam is currently, instead of at the end? Thanks in advance. I'm not very well versed in javascript. I'm trying to make a bookmarklet that when I click it will either append text to what I've already written or insert the predefined text at the cursor's position in a textarea. Also the browser I'm trying to do this on is Chromium. Here's what I have: Code: javascript:void((function(){document.getElementsByTagName('textarea')[0].value='ಠ_ಠ'})())
...but this of course changes the entire value of the text field to: ಠ_ಠ ...rather than appending or inserting at the cursor position. I'm guessing append would be the simplest, though cursor position would be most efficient. So if you can help in anyway, please do! Thanks. Hello there, this is my first post on this forum. I have learned a good bit of PHP and have implemented it for use in my work as a math tutor. My kids are telling me, however, that it is too inconvenient to hit tab or click on the next text box and would prefer to use the old style pencil and paper. I thought of a good idea: Javascript would be able to automatically focus the curser on the next text box if some condition was met. For example: 6+7. If the textbox reads 13, it will focus on the next text box. Otherwise, nothing happens. This kills three birds with one stone; the user will know if they got the question right or wrong and it will move automatically if they got it correct. The problem is I lack any real JavaScript wisdom. I would guess this would be quite simple. The closest thing I have found upon searching was this from the user requestcode, but this has to do with once the user has typed in 4 characters it moves automatically. Code: <SCRIPT LANGUAGE="JavaScript">
function nextbox(fldobj,nbox)
{
if(fldobj.value.length>3)
{document.forms[0].elements[nbox].focus()}
}
</SCRIPT>
</head>
<body onLoad="document.myform.txt1.focus()">
<CENTER>
<FORM NAME="myform">
<INPUT TYPE="text" NAME="txt1" SIZE="4" MAXLENGTH="4" onKeyUp="nextbox(this,1)">
Thank you for the help. I have a WYSIWYG text area and I want to insert combo-box' value at current cursor location of the WYSIWYG text area. I have a simple textarea where the value is inserting on combo-box clicking. But when I do integrate both files, the functionality wont work. I have both scripting files..
I already looked at this http://codingforums.com/showthread.p...ht=moving+text thread and I know it's similar. I just don't know what I am doing wrong. My css puts the text where it needs to go, then the script is supposed to alter it's pixel position and so it should move, right? Code: <html>
<head>
<style>
item1 {position: absolute; left:20px; top:280px;}
item2 {position: absolute; right:20px; top:280px;}
</style>
</head>
<body>
<item1 id="item1" >item1</item1>
<item2 id="item2" >item2</item2>
<script type="text/javascript">
var i=0; var j=0;
var obj1=document.getElementById(item1);
var obj2=document.getElementById(item2);
obj1.style.visibility="visible";
obj2.style.visibility="visible";
//if (typeof obj1.style.left!="undefined" && obj2.style.right!="undefined")
//{
//loop from ParseInt to coordinates in center of screen
for (i=0;i<100;i++)
{
obj1.style.left=parseInt(obj.style.left) + i + "px";
document.write("<item1 id="item1">item1</item1>");
document.close();
}
//for (j=0;j<100;j++)
// {
// obj2.style.right=parseInt(obj2.style.right) + j + "px";
// document.write("<item2 id="item2" >item2</item2>");
// }
alert(i);
//}
</script>
</body>
</html>
Am I anywhere close? I am trying this on IE6 (I only have Windows 2000) and on Firefox 3.5.3. If anyone has a PS3 and goes on the PSN Store (PlayStation Network Store) you will get what i'm on about but does anyone know how I can use Javascript to make it when a user hovers over some text it will marquee but start from the position it was? Example: A string like this wouldn't need to have a scroller when someone hovers over it: Hello but a string like this would: Hello i'm bob and how are you doing today?. as it would be to long to stay on one line in the div. So what i'm looking for is some sort of marquee that doesn't start off screen but calls the current texts position and then starts from there and then reverse itself to go from right-to-left to left-to-right when it's at the end of the text and when the user's mouse moves off the text it will just go back to its normal state. All text's which are to big for the div will have three dots added to the end and once mouse over they will go and the full text will start to scroll. If anyone can help me this would be a massive help. Thank You DJCMBear Hi. Stuck on an assignment, inserting 3 files that i am working with, unable to get the unhide or move functions working.

Hello I need to get text from an iframe. I tried this example (I've found it on this board): Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Example</title>
<style type="text/css">
</style>
<script type="text/javascript">
// <![CDATA[
window.onload = function()
{
// treat iframe_window as if it were your iframes window (which it is)
var iframe_window = window.frames["my_iframe"];
// compare the following line to: window.document.getElementsByTagName("body")[0].innerHTML;
var iframe_body_html = iframe_window.document.getElementsByTagName("body")[0].innerHTML;
alert(iframe_body_html);
}
// ]]>
</script>
</head>
<body>
<iframe name="my_iframe" id="my_iframe" src="example.html"></iframe>
</body>
</html>
but it works only with window.onload event. I need to get this text dynamically (e.g. on click). could you give me some example? Regards. Hi, I'm trying to locate some text within an iframe highlighting the string found. I was wondering if someone knows a good way to do Stickers I use the following code to create a hidden iFrame on a page, dynamically Code: var i = document.createElement('iframe');
i.style.display = 'none';
i.onload = function() { i.parentNode.removeChild(i);};
i.src = 'http://www.mysite.com';
document.body.appendChild(i);
i.id='frame1';
Now, document.getElementById('frame1').contentDocument.getElementById('text01').value Should have given me the value in 'text01', but it doesn't. It doesn't work even inside the iFrame's onload event. ('text01' is a textbox which is on the page inside the iFrame - its name and id are both 'text01') Is there any other method to get the text in a textbox within an iFrame? Please help me to correct the code. Thanks in advance. |
