JQuery :: Obtain The Content/value/index Of A Specific Position In A Dropdown?
Aug 1, 2011
i have a dropdown. i want to check the value in 'i'th position. how can i find that? $("DropDownList1_ID").val() is not giving any value. its alerting [object object] .
How can I obtain content of cascade style, using javascript? I know, there's a code document.getElementById('id').style.border='5px solid blue'; For example, but I need to do reversed operation, not to change style, but obtain it.
I'm really struggling to find any sample code for getting the start and end position of a text area selection (i.e. a textarea contains the phrase "Why isn't there a standard, well-known function that does this?" and somebody selects the word "there" -- using a function, I'd like to be able to grab the start position and end position of the word "there").
Can anybody help me with this, or am I going to have to hack together some long-winded function to do this seemingly simple task?
Let say I have the following form. I need to put the error message of the checkbox a bit differently from the other element. The point is that I don't want the error message between the checkbox and the text. Let say I have:
Name: [textbox] error here (required) Email: [textbox] error here (required + email) Interests: (at least 2 checked)
When I leave the first textbox (taborder 1), I need to check and see if the textbox contains avalue. If it does, then I need to check and see if the second textbox (taborder 2)contains a value. If it doesNOT, then I need to loadthe second textboxwith "100" and highlight (select) the text. I am adding a blur event to all the column one textboxes as they all contain"rawCount" in the id. Here is my blur event code:
$(document).ready(function(){ $('input[id*=rawCount]').bind('blur', function (event) { // Code to go here }); });
What I am trying to do isadd thecode tocheck and update thecolumn two textbox in the corresponding row (same index)to the blur event of the column one textboxes without having to loop the array each time to find the current textbox array position. Since it is adding the blur event, it has to be possible.
to be applied to an iframe? I tried changing "window" to the id but that failed me and I'm really just getting started with Javascript. I've spent the last hour and a half on Google but haven't found it.
Or, is there a better way to achieve what it is I'm trying to do? I just want to have my iframe automatically scroll to specific position on the webpage.
I'm looking for a content slider, somewhat like Coda Slider, but with the ability to load dynamically extra content. E.g. it loads only 4 slides (1 visible at the time), and when the user navigates to slide 3, I want it to load the next 4 slided. And on slide 7 again, etc.
I am trying to create a menue that takes elements with one of the following selectors .cata, .catb or.catc and fades all not matched elements out while fading the matched elements in (if already faded out). When one of the links ist clicked a second time (in faded in status) then all elements .portfolio (.cata, .catb and .catc) should be faded in.verything is working like charme. The only problem is, that I can't get all elements .portfolio displayed, when I trigger the link a second time.Here is what I did in jquery:
I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list. For instance,
I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list.Anyway, let me show you what I really want to do. Please see the code below. If you want to properly run this, please make six dummy images and name them as followed: silo_1_ empty.jpg, silo_2_empty.jpg, silo_3_empty.jpg, tm1.jpg, tm2.jpg, tm3.jpg.What I want to do next is to apply a restriction to the dropdown lists. For instance, if TM#1 is selected, only Silo1 can be selected from the LOCATIONS, and Silo2 and 3 will be removed from the option. If TM#2 is selected, Silo 2 and 3 can be selected and Silo 1 will be removed. TM#3 can be in all locations.
In total, there are 12 modules and 20 locations. Each module image can only appear in one location at a time, but the options to select a location are restricted.
$.get('filename.html', function(data) { $('.class_name',data).html(); //returns the HTML of .class_name inside of filename.html });
but it didn't quite work. It loads the entire web page into the defined class name rather than loading a specific content (Look below for further understanding)The filename.html which has content tag names like "[Copyright Year] that goes in the footer position of the site gets dynamically generated.I've created another static page help.html that has pretty much the same content overall except the dynamic content won't get loaded with the content tag (the system doesn't allow static pages to load them). This is what brought me to this solution. So now that I've added a class name to the indicated class that I want to load it pulls all the content and styling of the site rather than just the dynamically generated content of (filename.html) .
<div class="adp_footer">[Copyright Footer]</div> <---- Doesn't get loaded when I used any of the above mention jquery strings,
I'm trying to create an accordion (jquery ui) that shows information about its items when clicked. The information for these items is grabbed from 4 locations:- one to get the item's basic structure info one to populate an 'interoperability' info box where the 'service' and 'about' properties match a box like the 'interoperability' box, but for 'similarity' info a file with user-created 'annotation' information about sub-items that could be shown.
I'm using the code below to display a menu that opens when the mouse goes over the main menu item (try it in your browser to understand the behaviour).
It uses "position:absolute" and a switch between "display='none'" and "display=''".
However the problem is that - in Internet Explorer 6 the dropdown (<select>...) always hides the menu - in Mozilla the menu is hidden initially but after clicking on the text "Select" it isn't hidden.
How does that come and how can I overcome it? I want the menu to be above the other stuff when it comes up. Code:
I have a div that is float: left and has a bunch of divs inside it. Those divs inside are all position: relative. They also have z-index values. I want to know the actual height of the outer div's content when I add a div.
Here's the problem: Code: <div class="outer"> <div class="something_With_Z_Index_Of_Zero">Something</div> <div class="something_With_Z_Index_Of_One">Something</div> </div> (NOTE: Both inner divs have a height of 20px)
When I ask for either: outerDiv.offsetHeight or outerDiv's computedStyle.height, both give me 40 (or 40px). This is actually not right as the two inner divs are placed one over the other. How would I figure out the proper height?
there was any premade dropdown menu which opens based on what position you are on the page.
For example, when I'm on the top of the page and hover the mouse over the dropdown menu, the menu opens upward instead of downward because the navigation is mid-screen. But if I was to be more than halfway across the screen and still see the navigation as it was on top of the screen and hover the mouse over it, the dropdown menu opens downward as oppose to up.
I'm using a function to load a page into a div. When I add the class of the element I want to show (.contentpaneopen) Chrome and Safari show no content. It works OK in IE and FF.When I ommit the class it works on all browsers.
function loadContent(elementSelector, sourceUrl) { //Works in Chrome en Safari: $(""+elementSelector+"").load(""+sourceUrl+"");
I am trying to get the index of a li with a specific class. I know I'm selecting the right object because I can apply a CSS class to it (eg change border colour) but when I try to get the index it returns -1. But I know the object exists as I can alter it. :-s
jQuery(document).ready(function() { var active = $("#tertiarynavigation .bordered").get(0); var num = $("#tertiarynavigation li").index(active); alert("Index: " + num);
