Caret Position In A Text Field

Jul 20, 2005

I would like to determine where the current insertion point is in a text field.

Say I had a text field that held 80 characters. I would like to display to the
user the current position of the insertion point at any point in the field.

I have found the TextRange object and have found examples of how to insert text
at a particular location. I have not been able to find a way to return a
number depicting the current location of the cursor.

Caret Position In Editable Textarea

Mar 17, 2011

I've been able to find for an editable HTML textarea for a WYSIWYG editor. It can save and restore the caret position. It works on FF3.5+, IE8, but does not work on Opera 11, Safari 5, or Chrome 10. Any ideas why? I'm just trying to find some code that works on FF3+, opera 10+, safari 5, chrome 8+, and IE7+.

Saving/restoring Caret Position In A ContentEditable Div

Feb 2, 2005

I have a contentEditable element, and am using setTimeout() to call a function which changes the innerHTML of the div. Problem is that changing innerHTML moves the caret to the end of the text.

I need to keep the caret pos so the user can keep typing. I tried storing the caret pos with
cursorPos=document.selection.createRange().duplicate();

And then later restoring it with cursorPos.select() - which is IE only, but it doesn't work because the content of the div gets changed between calls, and the behavior is undefined (it basically selects everything) ...

OnClick Adds Text Field To Page (Limit 3 - Each Text Field Displays Different Text)

Nov 22, 2010

I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right

<script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";
[Code]....

Storing Scroll Position In Hdden Field

Jul 23, 2005

I'm working with ASP.NET serverside and am looking for an easy way to
retain scroll position of the window.

Is there any way that a hidden form field could *always* have the
current document.scrolltop value set to it? Especially right before any
posting to the server is done.

I'm using asp.net datagrid code that does not give me any easy way to
tie javascript functions to controls - otherwise this might be easier.

Basically I guess I need grab to document.scrolltop and send it to the
server (so that I can return it when redering the page onload). But
<body onunload=> does not seem to work with my asp controls.

From Caret To TextRange Object

Jul 23, 2005

in a DHTML Editing control (MSIE), I need to "extend" the caret to the
nearest text character in order to obtain a text selection (and than a
textRange object with the createRange method).

This is needed because I have a set of functions doing operations
within the edit control's rich text. But all the functions need to
start from a selected text (for example, adding a table row). My aim is
to get the things work also if no text is selected from the user. But I
could not find a way to have a selected text starting from the simple
cursor position.

JQuery :: Get Cursor/caret In An Editable Content <div>?

Apr 6, 2010

Does jQuery provide an abstraction for getting and setting the cursor for editable content div's? And if not, any assistance on how to do this? I really just want to pass the "id" and a cursor value to set it... or just the id to get the cursor value. Basically, I'd really like a high-level interface because trying to get it to work on Firefox alone is a massive pain :(

The fundamental problem is this:

If you have a div that contains text and other html elements, if the user's selection encompasses text and html, it won't do anything. I don't even think it registers.

Even when you do get a selection though, we can only find the cursor value within that range. So if there's html elements that are siblings to the left of it, the number of positions isn't accounted for.

I was I could just "get the selection information" and "store the selection information". When I try that, it still doesn't work :/

Linking Text Field To Hidden Field?

Apr 2, 2009

I have created a html purchase request form that people will fill out and submit to make purchase requests within my company. In this html form, I have a text field that is automatically populated when the page is pulled up. The text field is populated with the name of the person who is logged in and it is read only so they cannot be deceitful or anything.To get to this HTML Request form, you must log in through a webclient thus the server knows to populate your name because you are the one logged in. The text field populates because of its <input NAME = "OBProperty_CurrentUserRealName", which is a keyword the program identifies and knows to populate with the logged in users name into that particular text field.

That works all fine and dandy, so here is where the problem lies. When submitting the overall form request, the populated name isnt being saved/ carried over to the admin page so we do not know who it was submitted by.To make the persons name carry over and save, another field name keyword must be used.

Which is OBKey__163_1. Which it was suggested to me to make that the input name of a hidden field. I need "text field A" to continue to populate the form with the persons name using OBKey_CurrentUserRealName, then pass the persons name off to a hidden field containing the input name=OBKey__164_1, which will thus save/pass the persons name on with the rest of the filled out request form when its submitted.

Here is what I have:

<input name="OBProperty_CurrentUserRealName" type="text" id="buyer" style="width:100%" readonly="readonly">
<input name="OBKey__163_1" type="hidden" id="OBKey__163_1">

Cursor Position In Text Box

Mar 4, 2003

I need to control the cursor position in a textbox to do this, does anyone know how to place the cursor in the textbox at a particular position

The functionality I am looking for...
Excel provides data entry help based on previous entries i.e. if in a previous cell in a column I entered "Jim Bob" then the next cell I type a "J" Excel provides help by showing "Jim Bob" in a way that allows me to pick it or keep typing. This is the kind of functionality I am trying to get using JS.

In the code below I create an array of previous entries by the user over the last 45 days this all comes from a DB but that's not important here. When the user enters a key in the textbox I can pop the text box with a matching value from the array, only up to the chars entered.

The Problem or Question:
Is there a way to place the curser back into the last position and highlight the remaining part of the match from the array?

This is really hard to explain but if you ever used Excel you may have an idea of what I am trying to do. Code:
