JQuery :: Testing For The Existance Of A Dynamic Element
Oct 19, 2011
[url]
This is all triggered from a, input :select. If a specific option is selected, generate a text field to enter a reason. the generated input carries an id: txComments_01/01 (this being the value pulled from the attribute "data-date".
The client only wants one per week, so if it exists already don't re-create it
[code]so now if url is xyz.html, the i'm getting the content of that page through AJAX and loading it to a DIV element(x).....and then accessing the div elements "name","category" etc.,but if urls point to heavy pages, it's slow process to do this work. so I WANT TO CHECK WHETHER THOSE DIV ID's EXIST IN THAT PAGE OR NOT WITHOUT LOADING THEM and then GET THEIR VALUES IF EXISTS.
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:
Code: <script language="javascript"> <!-- // Max number of items to show/hide
[Code].....
Which is designed to hide all but one of a group of DIVs with consecutive IDs in the form "listings_stations_<number>". The problem is, I won't know how many of these DIVS there will be. I know a maximum possible number though.
The script as-is works, but obviously throws up errors trying to get handles to non-existent elements/objects. How can I check an element exists before getting and setting style properties for it? I'd like a solution that works for all three browser-types the script currently works with.
Im trying to make the VALUE element within a form dynamic using JQuery and was wondering if the following is possible and if not what is the way to achive this?
I have a problem, I have a table which dynamically create <tr> elements with a unique numerical id, this is created on a while loop from a database statement, when I click on a hyperlink on each <tr> I use this:
[Code]...
So in this way, I'm sending the unique code (codigo) and I fadeToggle the <tr> identified with that specific id, it works, no problem, it display with one click, hides with another one, BUT, now I need that, when you click on a hyperlink, if any other <tr> is being displayed at the moment, close all of them, and open the clicked one, is there any way I can do this?
I'm currently working on an IE7 CSS fix for a rather large form. Long story short, I have each input wrapped in a div, all in the same class. What I need, is to have each div define a padding-right value that is equal to the width of that div. I'm fairly new to jQuery, so I'm in need of some help with the syntax. Here's what I currently have, but it keeps printing a padding-right value of "0".
$('.form_label').each(function(){ $(this).css('padding-right', function() { var w = $(this).width();
I am echoing some dynamic content into a DIV based on form entries. The content is essentially a dynamic table, with results populated based on the user input. The user can further refine the database results by entering more data into other fields. All of this works fine. What I'd like to add is the ability to click on an <a> tag header on each column to sort by that column. I haven't gotten it to work, so I wanted to try a more simple test. I currently echo <a id='test' href='#'>Click Me</a> into the DIV set aside for AJAX response. I then setup a jquery .click() event monitor to simply alert me when I click on it. If I place this <a> tag in the main portion of the content that is static, I get the alert box. But when I put this into the content of the DIV tag generated dynamically by AJAX, it doesn't fire the alert. Is there something I need to do to 'reload' the page? Is the dynamically added content not part of the document since the entire page isn't reloaded?
On the right site there is a box with a vertical scrollbar. It´s a DIV (id="right") with an iframe in it. Maybe I´ll put a DIV with overflow:auto in it but it doesn´t matter now.
The customer wants that this 'scrollbox' takes all available vertical space. That means it should start right under the header and end above the footer. But when there is much content and the user scrolls down the page the scrollbox has to stick under the top edge of the viewport.
Does anybody know how to realise this?
I think I can use JavaScript to get the y-position of the scrollbox and then change margin-top of the iframe or padding-bottom of DIV id="right" or whatever. Code:
I've got a PHP script that pulls some records from a MySQL database in a loop. They're images, so what I want to do is have a javascript onhover thing where a big image will display depending on which thumbnail you hover over. The code I'm using is as follows:
<!-- this bit goes between the head tags --> <script language="javascript" type="text/javascript"> function showT(q) {document.getElementById('ima').setAttribute('src','../images/properties/'+q+'')} </script>
[code]....
Now this javascript does work, but of course it only displays the onhover behaviour in the first element, so if there are ten img id="ima"s on the page, hovering over their associated thumbnails only changes the img id="ima" at the top of the page. It would be useful if I could have the getElementByWhatever parameter accept anything from "ima01" upwards, that way I can just append $strID onto the end of the id name and make the unique identifier that way.
determine what the first letter of a selector is? For example, if the very first letter of a paragraph is a quote (or a ‘ , or a “ , etc) I would like to apply a negative text- indent to the found paragraph so as to replicate "hanging quotes" that are commonplace in the print world. The code I've come up with is: $("p:contains(“), h1:contains(“), h2:contains(“)").css({'text- indent':'-0.3em'}); but this grabs any p or h1 or h2 that *contains* an opening curly quote; not what I'm looking for. I need it to select paragraphs that *start* with the opening curly quote. Incidentally, I could not get this to work when I was searching for $ ("p:contains(“)... but it worked when I entered an actual opening curly quote in the search (as above top). I tried both single and double escapes too.
How should i read the text which is inside a divison.I have the divison id,but we cannot use getElementById because everytime the page is refreshed its id is changed.
I'm attempting to submit a form via a function which dynamically creates a hidden input:
function submitLocation(theForm) { var e = document.createElement('input'); e.setAttribute('type', 'hidden'); e.setAttribute('name', 'location'); e.setAttribute('value', Ƈ'); var f = document.getElementById(theForm); f.appendChild(e); document.forms[theForm].submit(); }
The function is called from an anchor's onclick event:
I have a select element that has up to 200 items in a drop down. Each <option> element has a value 1 to 200, ie., <option value="1">text</option>, etc.
Given a list of values, such as 4, 43, 123, 199, how can I use that list to call a function and write "Selected" for those option elements in the drop down menu?
I have form where I add dynamic html element as below. In the php code via ajax I have built the full drop down list. So when I post the form in IE when I do like this $masterID=$_POST['masterID']; I am able to capture the form value. But in both firefox and chrome it shows me empty
function getMaster(entID,nextElement) { var table = document.getElementById('myTable'); var rowCount = table.rows.length;
For some reason my change() function is only called when the page loads. I'd much rather it gets called when the select changes.
Here's the code:
window.onload = init;
function init() { var new_select = new Selector('tdata','myselect','myid'); var new_select_list = new DataSource("some_list"); new_select_list.addItem(1,"One"); new_select_list.addItem(2,"Two"); new_select_list.addItem(3,"Three"); new_select_list.addItem(4,"Four"); new_select_list.addItem(5,"Five"); new_select.setDataSource(new_select_list); new_select.formInput("form","input"); }
