JQuery :: Bind HTML Attribute To High-lighted Text?
Sep 29, 2010
I'm working on an interactive website where the user can change the font attributes of the text within the page they're reading. Is there a way to bind, for example, bold tags around a snippet of text the user has high-lighted? What I mean (if that wasn't clear) is if the user is reading through the text on the page and drags their mouse over a piece of text then clicks a button and it turns bold, much like a rich text editor would work, is this possible to do?
Couldn't find it in documentation.For example i have <span>text</span> and when someone clicks on it, itshould trigger checkbox to "checked" or "unchecked".
I'm trying to find a way to add an attribute inside an anchor. I want to do this is because that attribute is required by a script I have running on the page, but it is not valid.Just so it makes more sense the code looks pretty much like this:<a id="previous" control="-6" href="#"></a> and I would like to add control="-6" inside <a> via jQuery, only I don't know how.
is there a way in jQuery to bind variables to function calls similar as prototype.js does it? See [URL]
E.g. in the slideUp method of jQuery you can specify a callback that is called after the effect has finished. I would like to bind a variable to this call so that it is used inside of this callback as a closure.
I was wondering if someone could help me out with the following.I'm developing a webshop CMS in which you can create categories. By using jquery's ajax method I'm making a POST request to a PHP script which then handles all the data supplied to it. This works good and all except for the fact that after the query is being executed my HTML doesn't get updated, at least not as well as I want it to.I understand that the common way of working here is to update HTML in the success callback of the ajax method. But the thing is that every category is being displayed as a list item with an id attribute, this id corresponds to the id the category has in the database.If$.ajax tells me that everything went down smoothly and my query has been executed then there's still no way for me to know which id this new category has been given so that I can update the HTML accordingly.
What would be a "smart" way to tackle this? The first thing that comes to my mind is simply calling another script which figures out the last inserted id on the db but that would mean doing an ajax request in the callback of another ajax request? That doesn't sound right to me..
I am implementing a fairly large Javascript file that has many if/than's that decide whether to load new content into div's. I have noticed this is causing high client side CPU utilization. Is there any better way to do this besides having the example script below repeated many times... i need to keep CPU usage down.
Code: <script> $(document).ready(function() { //ajaxTime.php is called every second to get time from server
The jQuery library is definitely very useful for those who have development background experiences but don't have the time to learn Javascript in it's true nature. I've played with it on and off, on a few smaller sites I manage, and the outcome was truly amazing. I don't know Javascript at all, aside from the basics and I was able to create a very fun and fast UI very quickly for my visitors. I wonder though; Does the jQuery library hold up efficiency for larger sites?
I currently manage a site with over 1.6 million post, averaging around 15,000 post per day this month. With me not having the time to really learn Javascript and I don't have much of a budget to hire someone to do the work I want yet, it would seem logical to use jQuery if I already know how to use it, right? I just worry, with the growth rate for the site at it's all time high, I'm afraid that jQuery will do more bad then good.
Are there any high traffic sites successfully using jQuery that you know about? has anyone experimented with jQuery on their high traffic sites? Would it seems more sensible to hire someone to do the Javascript work?
Here's what I'm trying to do: 1) I get reference to a div that's on my page: var theDiv = $("#" + divID); 2) Now I want to add a custom attribute tag to it, so for instance I want to add "winWidth" so that the div object now contains "winWidth=" for instance. 3) I want to set winWidth now since it's part of theDiv to a value
I'm not sure how to really do 1 + 2. I need to do this on the fly because some javascript logic later will add these attributes dynamically to the div... outside of what the original div had...I don't care what it had, I know I have it now in a JS variable and now I want to both add some new attributes to the div, and then set them on the fly. I don't need these attributes to be on my page, I just need them added to my div variable reference.
We're trying to make all the HTML we write to be forward compatible so we're running our code through an HTML validator.The problem I'm seeing is that the 'rel' attribute is not valid for the <input> element. Although it works fine, is there a work-a-round for this?I've used the 'rel' attribute extensively since I've started using jQuery.
I am trying to see if the following can be achieved using Jquery I need to create a thumbnail gallery, where when a user hovers over any thumbnail image they would get an option to download the image either in High or Low resolution. Something like how you see in the below mockup.
I have a team website that has several games for entertainment. One of the games is a javascript version of yahtzee. Can someone suggest a way, using javascript, to record a high score for the game instead of a high score for a particular user, session, or computer. Perhaps someone already has code written to do this.
We are currently trying to locate the JS that will allow us to implement a progression of low-res-->hi res load for the big background images we have on each page of our new web site.In other words, we have a ginormous photo in the background, and want to avail the browser a very lo res version of said photo while the big photo loads.I have a feeling this is a real rookie question, but still, if there is anyone that can advise I'd be super grateful
I am a back en developer and really don't understand event driven/front end development so if I use newbie terms or make no sense please bare with me. Could someone point me to some tutorials on how I might render something if and only the local machine has good processing power/ram. I am going to be rendering some stuff which will require quite a lot of processing power on the local side. Just a threshold thing really nothing predictive or anything just if ram is more than 1GB and processor faster than a P4 or something like that.
I'm attempting to write a quick piece of Javascript code that will validate if the end user of the javascript has the necessary VML attributes set in their HTML. The problem in IE is that "xmlns:v" does not appear in their attributes property or the getAttribute('xmlns:v') calls. The real kicker is that the 'xmlns' attribute does return something.
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 $(document).ready and anyting else...
I cant see any syntax errors - i pulled the example from the 1.4 site. There is no trailing commas in the object notation and i really cant see any reason it would work in firefox and not IEx and more to the point not only not work in IEx but break any other jquery in the entire page....
I am fairly new to javascript but I am an experienced php programmer. I have been parsing XML information using php, but my CPU usage has been too high recently due to this. I am trying to convert my scripts to javascript, but I am unsure how I can do this using javascript. I think that if I get started off, the rest will be easy. One of my XML files is located at Code: http://ws.audioscrobbler.com/2.0/?method=user.getrecenttracks&user=bbcradio1&api_key=c910b0bc1e2d4e64964ebcd2d69c255c&limit=500 Basically I have been trying to grab the Name, Artist and large image of the most recent <track>.
I'm working with a large (and unweildy) ASP.NET application, and there is a lot of jQuery code that uses selectors like this:
[name=_aspnetControl$_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:
I was having difficulties storing text in the title attribute when it contained special characters.My workaround was to use escape/unescape.Is this the best way to resolve this?Why is it okay to include special characters in the alert function (i.e. Doesn't work), but not in the title attribute?
