JavaScript - Diagonal And Vertical Text Selection
Is there anything out there that allows for a diagonal and vertical text capture in javascript or jQuery? I was not successful in finding anything. I have a game similar to word find that I've developed, but I need to be able to capture text vertically and diagonally. Otherwise, the only solution will be for me to do a by-click basis to capture items on the screen. I found the script below which handles horizontal capturing:
Code: <script type="text/javascript">
document.body.style.cursor="url(3DArrow.cur), crosshair" ;
if (!window.Kolich){
Kolich = {};
}
Kolich.Selector = {};
Kolich.Selector.getSelected = function(){
var t = '';
if (window.getSelection){
t = window.getSelection();
}
else if(document.getSelection){
t = document.getSelection();
}
else if(document.selection){
t = document.selection.createRange().text;
}
return t;
}
Kolich.Selector.mouseup = function(){
var st = Kolich.Selector.getSelected();
sel_text=st.replace(/\s/gi,"");
if(st!=''){
alert("You selected:\n"+sel_text);
}
}
$(document).ready(function(){ $(document).bind("mouseup", Kolich.Selector.mouseup);});
</script>
Similar TutorialsHi, Here's a sample form: Code: <form action="#" method="post"> Name:<br /> <input type="text" name="name" value="your name" /><br /> E-mail:<br /> <input type="text" name="mail" value="your email" /><br /> <input type="submit" value="Send"> </form> When you tab to a text input, the value gets highlighted. How can it be disabled? Any help is appreciated! Mike I have 2 textareas, 1 which will be vissible, another that will be hidden. I have a function that mirrors (not in reversed lettering) the first textarea's input to the second. Code: function copy_data(val){
var messageText = document.getElementById(val.id).value
document.getElementById('message').innerHTML = messageText;
}
So that copies from : <textarea name="text_message" rows="4" id="text_message" style="direction:ltr;" onkeyup="copy_data(this)"></textarea><br/> To: <textarea name="message" rows="4" id="message" style="direction:ltr;"></textarea> Then I have another function which when I select text in the "text_message" textarea will apply a tag to it, however I don't want this tag to be vissible in the "text_message" textarea but rather in the "message" textarea. Code: function formatText(el,tag){
var selectedText = document.selection?document.selection.createRange().text:el.value.substring(el.selectionStart,el.selectionEnd);
if(selectedText!=''){
var newText=''+tag+''+selectedText+''+tag+'';
el.value=el.value.replace(selectedText,newText)
}
}

The data for the select menu is being pulled from a database (which works fine). The select menu is displayed as expected; however the text in the div tag always comes up as "undefined" The code below is part of a PHP script (thus \" instead of ") I would like to employ a method that does not require extra Javascript in the <head> section as in this instance the code is being output from an include that is called long after the <head> area of the document is processed. Here is what I have Code: <tr><td><select name=\"race\" onchange=\"document.getElementById('ExtraInfo').firstChild.nodeValue = this.options[this.selectedIndex].extrainfo\">
<option selected=\"selected\" value=\"\">Select Race</option>\n";
$sql = mysql_query("SELECT * FROM races");$i=1;
while ($row = mysql_fetch_array($sql)){
$output .= "<option value=\"$i\" ExtraInfo=\"{$row['des']}\">{$row['race']}</option>\n";
$i++;
}
$output .= "</select></td>
<td><div id=\"ExtraInfo\">Select Race</div></td></tr>
Any help will be greatly appreciated. I found a solution to my problem: by replacing: Code: <select name=\"race\" onchange=\"document.getElementById('ExtraInfo').firstChild.nodeValue = this.options[this.selectedIndex].extrainfo\">
with this: Code: <select name=\"race\" onchange=\"document.getElementById('ExtraInfo').firstChild.nodeValue = this.options[this.selectedIndex].getAttribute('extrainfo')\">
Hi all, I am working on code to wrap BBCodes around a user selection, then leave the selection selected for possibly adding more BBCodes around the same selection. My problem is that there seems to be several different ways to do it and I can't figure out which one is "the best". Now, I can't use the "standard" way of doing this because I am working with TinyMCE. I know there are countless examples on how to do this with textareas... that is NOT what I need. TinyMCE can give me a selection RANGE, a selection NODE or a selection OBJECT. Note that if I use TinyMCE's range, it internally "normalizes" the range to be a standard W3C range, regardless of browser. I've created a new range, extracted the selection from the user's range, created elements for the open and close BBCode, inserted the elements into the range and finally set the user's selection to the new range. Works fine. I also tried taking the selection node (which is an element), then simply used "innerHTML" to add the opening and closing tags, then set the node to the modified node. Works fine. I've also used the editor's built in "selection.getContent()" and "selection.setContent()" calls and THIS also works. I've even tried using the DOM "surroundContents()" function, then used a regex to change the < and > into [ and ]. Freaky... but that works too. So, my dilemma is... which method should I use??? To recap, here's what I want (blue represents selected text): This is a test sentence. (user selected some text) This [bbcode] is a test [/bbcode] sentence. (text is wrapped and remains selected). This [bbcode][newcode] is a test [/newcode][/bbcode] sentence. (user clicked another bbcode button). If no text is selected, then simply the open and close tags are inserted, with the cursor blinking in between them.... [bbcode] | [/bbcode] (pipe symbol represents the cursor) Any guidance will be greatly appreciated! -- Roger Hi all, I made up a little test program to grab the mouse X and Y coordinates and plan to use it to allow users to resize a window. Anyway, the problem I'm having is that in MSIE-8, the mouse down and movement causes text to be selected (which I don't want). Here's is a screenshot from MSIE: And here is the test program live online: http://three-dog.homelinux.com/mouse/index.htm Notice that the text in the box is selected ... I don't want that to happen. Of course, it works just fine in Firefox, but not MSIE. I would appreciate if someone can tell me how to fix this (and if possible look at my code and see if I'm doing it right - I'm not very skilled at events yet). Thank you. -- Roger I want to insert text to a textarea based on the selected text. It should insert tags like the buttons for posting on this form work. Ie: If 'bar' is selected, and I click 'b', then I get: Code: Foo bar frog becomes: Code: Foo <b>bar</b> frog I found some code that works for firefox, but I need it to work in explorer as well. Do you have any ideas or examples how to do this? Here's the code I'm currently using. ( Works right in ff3. In IE7 it appends the tags at the end of the text. I want it to insert based on my selection. ) Usage: Code: <a onclick="insertTags('<b>', '</b>', document.forms.formpost.text);return false;" href="javascript:void(0);">[ Bold ]</a>
insert function: Code: <script type="text/javascript">
// Surrounds the selected text with text1 and text2.

{
// Can a text range be created?

btw i know the alert part is wrong. its there because im taking the code i previously had and changing it to display in a textbox instead of an alert. thanks Hi all, Could someone please tell me how to properly add some text content before and after a user's selection? I am working with the TinyMCE editor, and I can get the following from it: * User's selection as a W3C compatible range * User's selection as a browser selection object * User's selection as a node (element) that encompasses the user's selection I also need the user's selection to remain selected after being wrapped. I've looked all over the web and could find nothing (except running into my OWN previous questions about this). Here's an example of what I'm trying to do: First line is original text, second line a part is selected, third line the selection is wrapped and the selection remains selected. I will greatly appreciate some help here. I've been asking everywhere and nobody seems to know (or they don't bother to answer). Thanks! -- Roger Hi all, I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County).

It's because of the formObject but I just don't know enough to resolve this!

Very, VERY new to javascript, hopefully this question isn't too bad.. So I'm looking at an example of randomly changing a picture through a function, I want to understand *why*, not simply know how.. The confusing code for me is: Code: while (that.src.indexOf(myImages[newImgNumber]) != -1) The other code is irrelevant. My question is, why would testing a current image with a new image result in -1 if they are the same? To me, it seems like it should be !=0? I mean, if I tested if a number was the same as another number, I would expect a result of 0 by subtracting. Is it not subtracting index position to find out if they're the same? Does it simply just return -1 if they are the same, and I'm over thinking it? Thanks for any help. Hello, I want to create a page that allows the user to select 2 images as options, when they click one, a new page is dynamically loaded with a list of options they can choose again (like a sublevel of the image they clicked on). From there it will just continue moving down like a hierachy Can someone help me with the basic script forthis to work so i can mess with it and edit it to my needs ^ Thank you in advance Hi, I have a page with a drop down and there are external js file that are included in the page which define handlers and other actions for onchange of this drop down. So if the selection in the drop down changes, we display a different color map (based on the selection). Now I have to pre-select an option on a specific page (which has been completed) and the drop down shows the correct selection, but the event is not fired (that changes the map color). Any idea what I need to do? Thanks as I have no idea if this will boil down to a JS problem, or a CSS problem, I've posted this to both forums. If some enterprising moderator would like to consolidate them, have at ye! Using javascript I've made a simple drag and drop interface for a backend component. Elements are dragged from a list at right into a main area. The elements are organized as a list (<ul><li>). Each has a mouse down listener which flicks on the visibility of a div (that mirrors the appearance of the named <li>) and then follows the mouse as long as it is needed. All is peachy... ... BUT THEN !!! ... As one might predict, the dragging action selects whatever content comes between the list item where the drag started and the placement where the drag ends. It's ugly and distracting; furthermore it changes my nice 'pointer' cursor to a 'text' cursor. I don't want to have to disable selecting for the entire page (nor do I know of a slick, elegant way to accomplish this) and I've tried all sorts of other hackery: cover up divs were especially fail-tastic. Hoping someone out there's cleverness gland can help me with this one. Excerpt from the site below to give an idea of layout: elements of the orange list at right get dragged into the main area in the middle I can't link to the site directly, sorry, I don't have a version ready that doesn't modify existing databases.

CSS thread link Hi all, I'm trying to do something with a WYSIWYG editor. Below is a piece of code that takes selected text and wraps various BBCodes around it. The code almost works... but I want a few changes and I hope someone has an idea for me. Note: the var range = ed.selection.getRng(true); line gets a W3C compatible range containing the current selection - even under MSIE. The editor takes care of this. Note: The var elem = ed.dom.create('span', false, ' '); line creates a SPAN element with the initial content " " and returns it's element in "elem". Code: var ed = (tinymce.activeEditor || opener.tinymce.activeEditor);
if(ed)
{
var sel = ed.selection.getContent();
var range = ed.selection.getRng(true);
var elem = ed.dom.create('span', false, ' ');
elem.innerHTML = bbopen + sel + bbclose;
range.deleteContents();
range.insertNode(elem);
ed.selection.select(elem);
ed.focus();
return;
}
This code works, but not exactly as I want. For example, if I type "This is a test" and wrap code tags around it, I get this: But what I WANT is this: Also, if I select no text and hit the BBCode button, I get the open tag and the close tag, all highlighted. What I want in this case is the open tag, the close tag and the cursor IN BETWEEN them ready for text insertion. I'm thinking that I can take the range start and end offsets and move them to get what I want, but so far I've failed. One thing I DON'T want to have to do is create THREE spans... one for the open, one for the selection and one for the close. Trying to avoid that if possible. Any help will be greatly appreciated! Thanks! -- Roger |
