I'm trying to grab a specific part of a string of text and am wondering how to do it (or if it is possible to do it) with a jQuery selector.Is there any way to get that specific part of the link?
View 2 RepliesScenario: you enter "foo bar" into a text field... Is it possible
through javascript to select/highlight just "foo"?
formObject.select()
selects all. I need to select only part of the string.
I have:
<div class="date">21-Mar-11</div>
I would like to select only the 21 and then only the "Mar" and replace the content of the div with "Mar 21," or something along those lines. The output is not the problem. I need selecting specific parts of the string. So I want to learn more about selecting specific parts of strings.

I am trying to create a Google Translate widget on my webpage, with just one language pair, Latin to English. Unfortunately the Google Translate AJAX API only supports a subset of all languages available, and Latin is not included. However, Latin IS included on the Google Translate website. Apparently languages that are in beta are available there, via a different server, while only fully released languages are available via the AJAX Translate API.a) I wrote a script that generated the XMLHttpRequest() call to the server the Google Translate website uses, but it always returned a '0' status code. I have since found out that this is normal, as these kinds of calls can only be made between pages on the same server.b) I then wrote a script that created a popup, and used the baseURL+params for the URL, , and this produced a pop-up window containing the translation result. However, as that page came from a different server to the server containing the script, I could not access the results on it. The code for that is here:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
[code]....
I know this can be done with form elements but I'm curious if this can be done with headers.
Code:
<h3 id="headTxt">Blah Blah</h3>
I'm trying to grab the Blah Blah text.
I've tried innerHTML but to no avail. (Does it have to be wrapped in a container?) Or is innerHTML a replace only?
While on vacation I've been writing a bunch of javascript/css text effects for fun and I'm planning to look into how I can implement my code inside a url. So now I want to know how I can recognise and grab the text from any random webpage and put it inside of a variable, my script can take it from there.

I am wondering if it is at all possible to create a button that--when
clicked--grabs a paragraph of text that a user has highlighted. So you
go to this website, then highlight a section of text. Once you have
the text selected with you mouse, you then click the button. The
button executes a function which acquires the selected text in a

How can I split a string like this:
IE, Firefox, Opera, Chrome, Safari
I want the string to be splitted after each ,
Then I want that each splitted part is placed in a variable, preferable in an array, so I can loop through the array with an foreach or something.
I am trying to do is load new content into a form without resetting the form. I have about 10 checkboxes, once 4 are selected I would like to reload a div in the page to insert four corresponding textareas with the same id as the checkboxes. So for example the checkboxes:
Code:
<div id="page_select">
<input type="checkbox" name="option1" id="option1" value="Home" /> Home
<input type="checkbox" name="option2" id="option2" value="About" /> About</div>
There would be about 10 after 4 are selected than four divs with textareas are loaded onto the page - These textareas have the same id in order for the right ones to load. If your wondering why not just hide the textareas and show when then have been selected by the checkboxes, its because they have a wysiwyg editor attach so it would start to load slow after I add say 10-20 different textareas.
Would this work:
Code:
$(document).ready(function() {
$('#reload_1').click(function() {
//var names = [];
var myScripts = new Array(4)
$('#page_select input:checked').each(function() {
names.push(this).attr("id");
});
$('#content_div').load('external_content.php.html # . + '. myScripts[0]);
$('#content_div').load('external_content.php.html # . + '. myScripts[1]);
$('#content_div').load('external_content.php.html # . + '. myScripts[2]);
$('#content_div').load('external_content.php.html # . + '. myScripts[3]);
If I had all the divs and textareas in external_page.php and load only the ones needed.

View 2 Replies View RelatedI am current building an information database for the company I work at...basically just a place for employees to get information and answers from. It is all hosted on a local server and I can only use javascript, html, and css. I've got everything made there is just one thing i want to add to it. Basically an "alerts and updates" page that only some people can edit without having to know html so if im not there they can post important updates. No computers have access to the internet so I did try some rich text editors but none of them worked. The layout I'm going for is kind of like this.
Alerts and Updates
Click on links to show updates: update 1 * update 2 * update 3 * update 4
Stuff goes in the update
[edit button]
You click edit it prompts you to login, bring up something to edit the text in that specific update you hit submit and it changes the info that was on there. The update links are linked to a script I wrote that just display the info below so when the page loads you see whats in update 1 then you click update and it changes the content to the next one.
Here's what I have so far, which handles characters
as they're typed in. Could someone please show me how I would loop
through all the values that are entered if a block of text was pasted
in, and then grab the ascii value(s) that are > 128?: Code:
I have a bit of a problem and as my javascript is a rather poor I'm struggling to come up with a solution. Basically I need to split the variable "#country" into two parts and call the second half as the "this" value for '#int-dc'. Using '+' as the start point end ending at the end of the string.
For instance 'this' returns 12+44 I want to split it to "12" and "+44" the latter (+44) replacing 'this' in the code below.
$(function() {
$("#country").change(function() {
$("#int-dc").val
($(this).val());
});
});
I need to extract a particular part of a string:
var str=(document.images('flag').src);
<img id="flag" src="../../../../img/ip/041-080/049p.png">
I only want the "041-080/049" part.
It needs to be read from the right, not the left because the preceding left part will vary in length.
I have this code:
function getLocation() {
var siteurl = document.location.href;
document.write(siteurl);
}
I want to extract from string etc. [URL] this part:"/page1/page2".How I can do it?
i have an expression, say "5*7 + temp". i have an algorithm that finds out that "temp" is undefined in that expression. now i need to change the color or background color of "temp" to show that it is undefined.
i know which position the "temp" is, but i dont know how to change the color of it.
I have a bit of html like this
<div id="J5">
<dt class="shade" id="profilefield_title_5">Member type</dt>
<dd id="profilefield_value_5">

This displays OK on my generated page anyway, but later when I want to use a switch statement on the member type it fails because of the spurious stuff I picked up in the variable
Is it possible to trigger an event ONLY IF a specific string is typed but not in a form field?

The reason I ask, is I have a barcode scanner and I want to be able to trigger a submit button next to the matching product on scanning the barcode. So basically, the user can open the page (and may have clicked on some elements already) then scan a product which will input a 13 digit number and the submit button with that matching id will be clicked/submitted. This is easy enough to do if I use a text input, but I a) don't want the user to have to click in the text box first. b) don't want the user to have to delete the text box to scan the next product.
Perhaps it can be done somehow with a hidden field that automatically resets on each scan?!?
The scanner works just like a keyboard as I have used it to filter products with keyup() in a text field...so it does actually activate keyup(). So it should have exactly the same affect if you type the numbers manually.
I have a script that is supposed to: Make sure that the user selects a performance from a select field Make sure that the user hasn't selected a performance that contains the string "SOLD OUT" in its value Here is the code I am using:

alert($('#paypal-purchase-date').val());
if($('#paypal-purchase-date').val() == 'Select Performance Date') {

You can't select the 'text' part of an 'a' element with css, e.g. in the statement <a>some text </a> you can't use a css attribute selector a[text = "some text"]{} to style the 'a' element. You can select all named attributes such as HREF, TITLE, etc. Does jquery's .attrib map strictly to the css usage or is there some way I can match on that part of an 'a' element?
I need this because a menu list I'm working with doesn't by default require a TITLE element so I can't assume I can match on this attribute.
I'm curious if there is a possibility of being able to search the whole document for a specific string using replace("that", "this") for example to find any reference to "this" and replace it with "that" and then show the modified content.
