Jquery :: Detecting Specific Value Of Attribute
Mar 29, 2011So I want to do something like this:
if($('.class').attr('Attribute Name') == 'specific value')
Is that possible?
So I want to do something like this:

Is it possible to call a function when user clicks on an (x,y) point (or a small area). I can't place a new object and just set the "onclick" value, so is it possible to do it without that?

So far the only close-but-wont-cut-it solution seems to be looping through navigator.plugins and check for plugins known to support these schemes, but that wont cut it (not maintainable, lacks perenity and have not found such a list). I have HTML anchor tags which use the geo [URL] and tel [URL] uri schemes. These are recognized by the iphone web browser (at least, tel I'm sure of) but not by the more general browsers.
If I click on any of these links in an nonsupporting browser of course, I get a nice browser alert box telling me the scheme isn't supported. But you cant trap that with javascript. I've tried fiddling around with window.navigator and even tried some iframe embedding magic to see if this would work, no success yet. What I want to do is detect I the scheme is supported and if not, prevent the links from a) appearing as links and b) be clickable. So far, I've been able to hack something out of firefox with this:
Code JavaScript:
(function(){
var schemes = ['aaa', 'aaas', 'acap', 'cap', 'cid',
'crid', 'data', 'dav', 'dict', 'dns', 'fax',
'file', 'ftp', 'go', 'gopher', 'h323', 'http',
'https', 'icap', 'im', 'imap', 'info', 'ipp',
'iris', 'iris.beep', 'iris.xpc', 'iris.xpcs', 'iris.lws', 'ldap',
'mailto', 'mid', 'modem', 'msrp', 'msrps', 'mtqp', .....
How can I find all TR that have any attribute starting with 'c'.
something like
$(TR[^c]).css("background","yellow") <-- doesn't works
I have an image map with various areas on it. A user can click on the various areas and something happens. That said, I sometimes need to disable the ability to click on some areas. For instance areas whose id attribute contains 0 0. I have the code to split the id and grab whether the values are 0 or 1 and the alert pops up when one has 0 0 in the id but it's still clickable. I thought .unbind would do the trick, but it isn't. The alert is simply for testing.
$('area').each(function(){
// Use the each() method to gain access to each elements id
var idToDisable = $(this).attr("id");//get id of area
var splitID = idToDisable.split("_");
if (splitID[3] == 0 && splitID[5] == 0){
alert(splitID[3]+splitID[5]);
$(this).unbind('click');
}else{
}});
In js, I can define my object by:
function myobject()[
this.name="test"; this.value="test"; this.status=0;
...
}
I can tell if the object has a attribute by
if(myobject.maxvalue)
...
but what if I want to check if a attribute name in variable?
for example,
var attrname="maxvalue";
is there a call like myobject.item(attrname) or something so I can test if the attribute maxvalue exists?
I have the following html code snippet
HTML Code:
<div class="clan_arrow sliding"><div>
<a onclick="Clan.memberInfo(this, event)" memberid="1234567" style="margin: -5px 2px;" href="#" class="sexy_button_new"><span><span><img src="picture.png" style="margin: 0px -4px; height: 15px;"></span></span></a>
</div></div>
if you click the link, it expands some other html stuff, so this is a javascript link. there are up to 100 of these links on the page and i am trying to expand all with a one click bookmarklet.
i tried already to fetch the links with a custom js function named "getElementsByAttribute" but that didn't went out well and i didn't get any results, no matter what parameters i used with the function.
so i'm searching for another method for fetching all the methioned links or some correct solution using the named function. and i think i will might have problems with clicking/activating them all. ps. that is the first time i'm actively using javascript.
I am currently attempting to write a function that retrieves the name attribute from a list of items with a specific class name. To illustrate:
Code:
Show types of food:
<input type="radio" name="food" id="fruit" onclick="setVisibility('fruit')"/>
<label for="fruit">Fruit</label>
<input type="radio" name="food" id="vegetable" onclick="setVisibility('vegetable')"/>
<label for="vegetable">Vegetables</label>
<li class="art" name="fruit">pear</li>
<li class="art" name="vegetable">celery</li>
<li class="food" name="fruit">banana</li>
<li class="food" name="fruit">grapes</li>
<li class="food" name="fruit">orange</li>
<li class="art" name="fruit">grapes</li>
<li class="food" name="vegetable">lettuce</li>
<li class="food" name="fruit">apple</li>
<li class="food" name="vegetable">spinach</li>
<li class="food" name="vegetable">cabbage</li>
I would like create a function called setVisibility to iterate through all the list items where class=food and return the value of the name, so that I can compare that to the radio box, and set visibility accordingly.
i have found a possible bug in 1.4 but it's only in Internet Explorer 7 & 8.The following code does not work and completely ruins every peice of jquery on the page (that means everything inside $(document).ready and anyting else...
$("<div/>",{
id: 'tooltip-'+rand,
class: 'dock-tooltip',
[code]....
I cant see any syntax errors - i pulled the example from the 1.4 site. There is no trailing commas in the object notation and i really cant see any reason it would work in firefox and not IEx and more to the point not only not work in IEx but break any other jquery in the entire page....
I'm working with a large (and unweildy) ASP.NET application, and there is a lot of jQuery code that uses selectors like this:
[name=_aspnetControl$_withASubControl] And unfortunately, some selectors that also look like this:
[name^=_someAspNetControl$_radioButtonList].
In other words, the effort to remove the $ from the attribute selectors would be monumental. If it is possible to escape the $ symbols, I can do that easily enough, but unfortunately the situation right now means that I can't upgrade to jQuery 1.5.
I'm learning jQuery with XML. I'm familiar with other query languages such as XPath. I'm having a little bit of difficulty wrapping my brain around how jQuery works but I think I can make the leap if I see a solution to a problem I know how to solve with other methods Given the following XML, please share a jQuery solution to finding the value of attribute B in elements named bar where attribute A has the value 30:
[Code]...
<div class="box top"></div>
<div class="box main">
<div class="box header">
<div class="badge"><ul><li class="active"><span>60</span></li></ul></div>
[Code]....
What is happening is $(this) is no longer based on .expand being the (this) that is clicked.
like if i have a button SOMEWHERE randomly on the page with this
<div onclick="Minimize('_alerts');">Click Here</div> this will minimize alerts but because the (this) in minimize function doesn't actually point to the right button that I want to add a class to.
Is there a way to modify the minimize function so that it finds the <div id="mytoggle"><ul> <li class="expand boxminimize" rel="_alerts"> using the rel toggle, and then changes the class of the li from expand boxminimize to boxexpanded??
just like the .expand click function I posted on the top of the post that works?
I'll trying to tell the difference between the following three cases:
<img alt="text string" />
<img alt="" />
<img />
I can do this in Firefox with the following code, where elem is the
HTMLElement representing each image, but IE doesn't seem to
differentiate between empty string and undefined.
var alt = elem.getAttribute('alt');
alt = (alt) ? alt : ((alt===null) ? 'really_null' : "");
The desired output from running this code on the 3 tags above is:
text string
really_null
It seems like this should be really easy...but I'm having a really
difficult time trying to figure out what's going on...
Another thing that has been driving me crazy is that css positioning is handled differently by different browsers. JS is not my area, but I can do a lot with CSS, and I do, but cross browser compatibility is killing me.
I can use an IF IE statement and only IE runs that segment of code, but I haven't been able to figure out out how to make ONLY firefox or ONLY opera or safari enact an encapsulated segment of code. The same type of IF statement doesn't work for them.
Is there a single method using JS that works for all browsers?
I know this code works just fine:
function result(){
var result = document.getElementById('resss').innerHTML;
}
But what I actually want is to import data from a table of an external website. E.g. I want to get the innerHTML of a specific cell in column 3 and row 2 of a specific site.
$(document).ready(function() {
The SELECTor shows up in the document but it's not MULTIPLE, no ALT text, no CLICK event handler.
The documentation for $.ajax() says that when the error callback is invoked, the error string may be null or one of "error", "abort", "timeout", "parseerror". So naturally, I assumed that if I were to call .abort() on the XHR that $.ajax() returns, the error string in the error callback would be "error". But that seems not to be the case. What I'm seeing, in jquery-1.4.4, is "error" as the error string. Has anyone else seen this problem? I'm using the most recent Firefox on MacOS X 10.6.

View 2 Replies View RelatedI have a jquery-powered "start page" that checks your log in and if successfull it slides in a "menu" of new places to go. The problem is, if you click back from one of the new places, the original "start page" looks as if you never logged in. You have to reload the page. Not very intuitive and this website is for kids. Now I've tried setting form field values with server session variables, javascript variables, etc etc but they all get reset when you click back. I've tried the "onunload hack" which I don't fully understand, and then read a bit about the onhashchange event which is from what I gather only compatible with HTML5 browsers...is there no way to detect if the user is already logged in when they click the back button or am I not doing enough homework?

So, I'm new to jQuery, but have a pretty good understanding. Still, I've come across an issue that I'm not quite sure how to resolve. I'm using wordpress, and have a .swf inside of a div, "player." The player class has no height spec, as the height of the .swf is different depending on the page. What I need to do is detect the height of the .swf on each page, and then apply that number as padding-top to another class?
View 1 Replies View RelatedI was wondering if there is a way to detect when a page has completely finished rendering? Is there an event in the JQuery library or JavaScript in general to detect when a page has completely rendered. I'd like to get some timing information for how long it takes for a page to render. I'd to do this offline to see how much CPU performance affects web page rendering.

Here's the sample code:
I was looking for the way to detect outgoing click on middle mouse button. .click() only detect main button click.
