JQuery :: Finding Non-Predetermined DOM Insertion Point?
May 12, 2010
How can jQuery locate a non-predetermined DOM insertion point? My application relies on custom code to "bootstrap" itself. I'm wondering if similar functionality is available in jQuery?
My app works in the following fashion:
- user places a script tag in their web page.
- my script fires and performs the following routines:
- scriptLocation = whereAmI()? (find scripts in document, length -1)
- insertBefore(DIV, scriptLocation);
- use DIV as canvas, DOM target for all that follows
- install application in DIV
Note that my custom app does not wait for any kind of "ready" state. It has no dependencies on the surrounding document. It fires inline. My impression is that jQuery's approach ("Find something, do something") is incompatible, because it relies on a known DOM insertion point. It would seem straightforward to "query" the DOM, and find an element of known ID. That would conflict with my business constraint; I have no control over the destination page. Are my assumptions about jQuery true? Or is there a way for a jQuery script to wake up, find its location, and the install elements there?
But the speed is considerably slow when the datas is large. I know that I can use just string concatenation and html() finally to speed it up but what can I do with the data()?
I have a button next to a textarea when they click that button it launchs another window. Now I need another button that will take a value (it will be an html code) close that window, and put that value in the textarea.
Sort of like how when you click the link button in this wysiwyg editor it pops up a window that asks for some stuff and then inserts it here.
Essentially, I am building an image upload plugin, and what the image inserted automatically at the end of the process, so I thought I would put this at the end of the script:
If that is run, then the actual image appears in the editors instance. Is this a general JS / DOM issue (I got it to work with the original script before, I just stupidly overwrote the file!), or, is it something more?
I'm developing a webpage that is composed by several divs. These divs are supplied by the server depending on the user that made the request. Some of these divs require some javascript functions to be called when they are added to the page. I add the content using innerHTML (function renderPage(data) ....
ive need to format the date (variable "tomorrow") in this form to mysql format yyyy-mm-dd can anyone please show me how to amend my script?
<script language="javascript">
function showDate(thisObj){ /* create a Date object using the system clock */ today=new Date(); td = today.getDate(); tm = today.getMonth(); ty = today.getFullYear(); tomorrow=new Date(ty,tm,td+1)
/* convert contents to string and place in control */ document.getElementById(thisObj).value=tomorrow; }
I am stuck with an issue in my project from completion. My program is trading exoeriment with 2 groups. If any user in 1 group enters value in filed called askvalue, this value must must be updtaed to all other users in the group. I tried to do thi by inserting and updating the table. Values are updating correctly in table a but weppage s not being regfeshes to other traders in same group.
I am posting my code here:
When any user in the group clicks this button insertion sql statements have to executed and then refesh the webpage for all the traders in the same group without clicking refresh.
I am trying to create a WYSIWYG editor for my site, but seeing as how every browser gives different results when using the execcommand method, I am trying to do my own insertions instead.
What I would like to do is create an iframe with designMode On to enable editing of the frame, but when someone does a command to bold text, I want to make a method which enters <b>Some Highlighted Text</b> into the frame where the user highlighted so it would appear bold and the source would have the <b> tags.
My issue is I have been unsuccessful in learning how to take the selected text within an iframe and surround it with tags. I was able to accomplish this in Internet Explorer using this code:
Except the resulting text would actually have the <i> tags appear, and the source would be:
Pretty retarded if you ask me since in no way did I want it to convert the tags into entities.
Anyway, if anyone could please direct me to a method in which I can successfully take selected text within the iframe and surround it with HTML tags in such a way that the formatting will actually show.
I have got a DIV that I need to refresh, its content consists of an image that will change on the insertion of a row to the SQL Database, however, when I use a refresh on my div it does refresh but does not change the image...
My refresh code is ajax:
And my PHP code contains the MYSQL that has a mysql_num_rows, so that PHP can see if there are rows or not.
I would like my page not to redirect or refresh on my div change.. So I would just like my div to refresh.
on my contact page, I have some hidden divs. One is for a google map. This div is only shown when the user has clicked to open the div. As I am working with smarty my template looks like this: <span id="gmap"> literal}
in FCK-Editor I would like to do the following:On one page there should be severalHeaderText under the header, which is hidden, when the text is loaded and slides up and down after click on headerHtml, which is easy to edit with FCK could look like this:
<p><a href=""><span class="click">Header</span></a></p> <p><span class="text">Text under the header, which is hidden, when the text is loaded.</span></p>
I have a client request I need a little advise on with an image slider.Client says;"There will be 4 photos that roll over two times each then stop on the Home Page photo then opens a text box over the left of the image"The part I'm not sure how to do is how to set the slider to stop on the Home Page image after the 4 images go through the animation two times.
I am doing some maintenance work on a classic asp web page that displays product information. I am changing how the page looks up the available quantities for the various sizes. The old method used several SQL queries to determine the number of sizes and available quantities and then used those results to build a table on the fly on the page.
My modification consists of a web service that consolidates product size availability from three different sources and delivers the data via an XML formatted return. I have also added DOM tags in the table that is built on the fly that identify each entry with the product id and size. So, for a product that has an ID of "P12345" and a size of "XXL," that corresponding cell in the table gets an id tag of "P12345_XXL."
My jQuery update statements worked just fine using this approach until the sizes included decimal numbers. My example for this is shoe sizes. A size represented by an integer (6,7,8,...,15,16,17, etc.) works fine. A half-size represented by a decimal (6.5, 7.5, 8.5,...) does not. Even though the period is contained within a string value, jQuery doesn't seem to be able to match the value with an id tag - and yes, I have verified that the two (the string that I am giving to the jquery select and the actual tag) do indeed match.
So far, the only work-around that I have come up with is to multiply numeric sizes by 10 and parse as integer values. Is this a "known issue" and is there a more elegant solution topursue?
I am trying to modify the ExpCollGroup function within Share Point (2003) and don't have access to server or ows.js file where the function lives. I want the ExpCollGroup function to run (I'm using it to expand/collapse documents in a document library), and then when finished, want to be able to run my own function like DoSomething(). The below code works but fires before the ExpCollGroup code executes. What can I do to make the ExpCollGroup function execute, and then perform my DoSomething function? $('[id^="img_"]').click(function() { alert(The Expand/Collapse button was pressed but the loading of documents has not yet begun');})
I understand that the very essence of the web is point and click however what I'm trying to achieve is anavigationsystem using a series of static 3D Render images have them seamlessly stitch together creating apseudowalk througheffect. For example if a user clicks on a hot spot e.g. a drawer it will fetch the same image but with the drawer open. or if a user wishes to go 'deeper into the scene e.g. a walk-through style effect then they would click on the hotspot and the image presently loaded would zoom out and and fade out loading the next thus giving you forward motion
mentally speakingIunderstand this to be perfectly simple to do technically speaking not so much this at the moment is acompletelyconceptual idea with no coding as I'm still attempting to get my bearings with jquery i was curious to what peoples thoughts were on the idea whether or not it is possible to do?
I'm using a third-party chat application. They require that form field names be formatted "SESSIONVAR!FIELDNAME". The bang is creating headaches when I try to write validation script. How can I handle this format properly? I'm not sure how to escape the exclamation point within my code.
