JQuery :: Selects Objects When Using An Id Selector?
Apr 13, 2011
where can i find an example of how jQuery selects objects when using an id selector? i'm asking because i've been using a cross browser snippet to select objects and i was wondering if it's the right move to move from the snippet to jQuery. the snippet checks to see for availabe methods and depending on the one that works, it knows which browser the user is using and selects the object using that method. i also know jQuery is cross browser, so it's kinda implied, just wanna make sure.
I have code to add a row dynamically to a form in my page when an element with class 'addRow' is clicked. The tables (2 tables in one page) that I want to add the row to have class 'tableAddRow'. The tables are contained in a form. But for some strange reason the code only adds to the last matched table in the page. I tried using the $.each selector but nothing works.
Here is the code: $(document).ready(function(){ $(".addRow").click(function(){ $(".tableAddRow tr:last").clone().insertAfter(".tableAddRow tr:last"); $(".tableAddRow tr:last input").val(""); }); });
Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.
I need to know how to reload a component using jQuery, i got 2 selects in a page the 2nd one is populed by the 1st one value, how can i reload just the 2nd select w/o reload whole page?
Each one belongs to a student so the # in the select name/id = student_id. I want to set a value in a text box based on the value selected for that particular student.
Rather than having a script for each select, can I make a single script that can determine which select was changed and then change the text box accordingly?

I'm using the jquery autocomplete plugin.Suppose the user starts typing, and the autocomplete presents a drop-down of possible values. If the user presses return, the first valuein the drop-down is selected.What I want instead is the user experience that Firefox's search boxprovides: As the user types, search suggestions are offered. If theuser presses return without selecting a suggestion, what the user hastyped so far is submitted. And of course, if the user does explicitlyselect a value from the drop-down, then the selected value is
I have a table that contains a select element like so
<tr><td>key value in hidden input</td><td><select>options</select></ td></tr> I need to set $("selectclass").change(function() { //Find the value of hidden input in 1st cell of row of the select list that was changed. });
So when a user changes the option of the select i need to get the new value the option has been changed to plus the value from the hidden input and submit them via ajax to a method on the server. How can i get the hidden inputs value?
It works well! But my script actually clones elements of the form so a user could be selecting adult or child for a number of tickets - ticket1,ticket2,ticket3....
How can I adapt that script so that it will show/hide for each ticket
I'm currently using h5validate with my forms but recently setup a few where a second form is generated based on what a user selects from a dropdown menu (via AJAX). Since the new form ID's were not existing when the document was loaded jQuery does not bind h5validate to the new form. I found a plugin called livequery that will bind new elements on the fly. Unfortunately, I'm pretty new to jQuery and can't quite figure out how to make this work with h5.
My current h5 function looks like this, where formID is the ID of the from that does not exist but is later loaded in via AJAX.
I have a scrollbar that I programmed. It is just like a scrollbar in a browser - click on the scroller and while holding the left mouse button you drag the scroller to move the window.
These are the issues I am having: if the target I use to be the scroller draggable target is an image, the image when clicked and dragged will be dragged as if I was trying to pull the image onto my desktop to be copied.
- if the target I use to be the scroller draggable target is text within a div, then sometimes it will select the text as if I was selecting to copy/paste
- sometimes while dragging the div as a scrollbar, the speed of my mouse will 'beat' the REPEATED CLICK speed (and it is set very fast) and I will "DROP" the scroller.
- Also when dropping the scroller, the page will select EVERYTHING as if I am trying to select all of the content in the page (SELECT ALL) and everything turns blue.

I have difficulties placing a menu over a select box. Whenever a menu item pops up over a select box, it's not rendered right above the select box. The menu will not appear over select box which splits up into two parts: one part with items above the select box and a second part will all remaining items below the select box.
It works in netscape,but not in "IE". i hv tried to add the specific z-index, but still fail to display in IE. some people use <display:none> to make the select box disappear. However it will look strange if the select box is bigger than the menu.
what i want to do is create several radio buttons and a textbox for searching purposes. the search will perform a search depending on which button the user selects.
here is what i have now:
- for each radio button, i use the onClick event handler, which calls a function called showMe()
- showMe() { if (button 1 was selected) document.write('form which will search down path A'); else if (button 2 was selected) document.write('form which will search down path B'); else if (button 3 was selected)... }
this works, but once the user makes their selection, the search form will pop up on another page. how do i fix it so that the search form will display on the same page as the radio buttons? Is there any other way to accomplish this?
I've had the following script developed which selects a second radio button when the first radio button in the pair is clicked (with the second button greyed/disable but still displaying the selection). While the script works perfectly, posting the radio button value via a hidden field, I need it to have one set of radio buttons checked by default (which I've indicated in the code... "checked"). Only problem the "Price" value isn't fed to the hidden field when the buttons are prechecked.
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "[URL]"> <html> <head> <title>Test</title> <style type="text/css"> form p { margin: 0; } form div { margin: 1em 0; } .....
function clickWhileDisabled(el) { // Firefox takes its time to enable the field, so delay the click and disable el.removeAttribute('disabled'); setTimeout(function (el) { return function () { el.click(); el.setAttribute('disabled', 'disabled'); }; }(el), 1); } </script> </body> </html>

Assume: Rows A, B, C, etc..., and Dropdown selection: 1, 2, & 3If dropdown in Row A selects 2, then I want the selection of dropdowns in rows B & C to dynamically change to 2.And if in Row C user selects 3, then the selection in dropdowns in rows A & B should dynamically change to 3.
