JQuery :: Getting Html From TD By Chaining Elements With Tags And IDs Within Scope
Jan 21, 2010
I've been programming in jQuery for some time now, and for the first time, I came across an issue where I am writing out the location of a TD with an ID="step" to get the innerHTML with html(). I receive a null value, but when I use td:first within the chain of elements, it works.Has anyone experienced this issue or have any idea why this is not working? I've tried other TDs with diffirent IDs within the same row, and the same null result happens.Is there a possible limitation to the numbe of IDs used within the chaining of the $() call?
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.
I am trying to wrap <a> tags around text in <li> elements. How can I get the index of the <li> in the <ul>? I tried something like this: $('.tabbed-list li').wrapInner('<a></a>'); That works fine. However, I want to do something like this: $(this).wrapInner('<a href="#' + $(this).index() + '"></a>');
I have now been playing around for hours trying to figure this out. Swore I would not ask for a solution. Now I have a headache, so I am asking. On one HTML Page (From.htm) I have:
[Code]...
I somehow, need to get the values as shown in the handle function for each of Products shown in From.htm. Keep in mind the only thing I know from From.htm is the class names. I have no idea what products are listed or what the input names are. This table is generated by a third party. Assume that index.htm and From.htm are on the same website.
So, I doing this bit of code for a pagination, but havingproblemswith my next, and back buttons.So I cam up with the idea to store the current page number in between two <p> tags. So the say the current page is 5, it would be shown in html as <p>5</p>My question is, with using jquery, can i get the 5 from the two p's, ive manage to stick the 5 into the two <p>'s using jquery, the code:$("#current").html(pageNum);with #current being the <p> id and pageNum being the 5.i have triedvar prevNum = $("#current").get(0);for getting the number but didnt work also here the jquery code, incase you want a full scope of what going on
I have some auto-generated code in a similar format to this:
<li class="item"> <a class="link1" href="#">Post Title</a> Text I want to remove <div class="content">
[Code].....
I want to select the line of text ("Text I want to remove" - with no HTML tags around it) and hide it using CSS (or remove it all together, if I can). I have tried using insertAfter to put a start <span> tag at the start of the line, and insertBefore to close the </span> tag at the end of the line (so I can apply CSS display:none; to it), but clearly JQuery doesn't work like that.
Is there another way to get rid of this line of text?
im using .load to get a part of a html site into my div.Problem:For exapmle i have some markup like:<strong>some text</strong>When i load this content the tag is closing befor of the strongtag.Looks like this:
I am putting the finishing touches to a custom written (pHp) article editor to allow users to publish content on a website.I have basically finished the project, and I am putting the finishing touches in with jquery widgets, such as a word counter. I would also like people to be able to highlight a section of text, then have some custom tags wrap the text (much like on this forum when you highlight a word in the message box and hit the wrap button).I would like my own custom tags to be used, such as <span class='someclass'>some entered text</span> rather than predefined ones.
Is there a way to change html tags without touching the inner html? For example, changing all h4 elements to an h2. Maybe something like this? jQuery('h4').replaceWith('<h2>' + (this).html + '</h2>');
I have a system receiving an html document as an array of lines, an am inserting this into a div using .append().
If an html tag is opened in 1 line (array element) of the string, and not closed within the same line, .append() automatically closes the tag on the same line, though there is already a corresponding close tag later in the html string.
Minimal test code:
$(document).ready(function() { var testString = [ "<pre>Test line 1 ", "line 2 ", "line 3</pre>" ];
[Code]....
Is there an append alternative without this behaviour?
suppose i have a strings (html):Lorem ipsum dolor sit amet, <span id="display_only">consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. </span>Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat.How can i display only the text whicj is inside the #display_only tag.... So that the result would beonsectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.
I would like to include extra "hidden" information in a generated HTML page that can be used by javascript functions.
I realise that most browsers seem to ignore any tags and attributes they don't understand, but from what I can tell the standards do not allow me to make up my own tags or attributes as they will fail validation.
is there any standard element name that can be used for such a purpose i.e. passes validation but never produces any output (and ideally allows nested elements to be rendered normally too)...
the following code works fine, but the span is NOT a child of the Li element. Instead it is a childof UL. If I remove the .data() from the chain, that SPAN is created as a child node, like it should be.
just a quick question about syntax.What's the difference between the following functions?
$("#menu li").hover( function(event) { if ($(this).is(".active")) return;
[code]...
If you notice, at the end of the first hover function, there is an excess (), whereas on the second, there isn't. They are both functional. I was just curious as to why this is added sometimes and other times not.
The application I'm working on dynamically generates a HTML table like the one below. Having identified that I need to add an opening <tbody> before the first TR that contains the word "Diagnosis", opening + closing TBODY to all other TRs containing the word "Diagnosis" & Closing </TBODY> after the last closing TR?
I'm trying to select a line a text and format it, only problem is there are no tags around it other than a closing </p> tag and a <br /> tag after it. Please see below the line in bold text which I'm trying to surround with <h3></h3> tags. [code]...
OK so if I use repsonseText responseXML or just try and traverse msg it will not work. The problem is the body of my XML response, all of the tags ('<' and '>') are getting escaped to html entities ('<' and '>') So it becomes a malformed XML document that is not readable. I even tried using the Javascript function replace to go through and replace with no luck.
Even stranger if I access the web service through the browser, the XML is just fine!
The server is Windows Server 2008 running IIS 7 and I am programming of course in HTML and newest version of JQuery.
The browser I am testing on is Firefox with FireBug.
In pseudo code, here's what I'm trying to do with some text: shrinkText.changeText.EnlargeText. The jQuery I'm using for this: $('span#calendarNumber').animate({ color: '#999', fontSize: '12px' }, 500 ).html($('#calculatorSampleInPopup1').val()).animate({ color: '#900', fontSize: '40px' }, 2500, 'easeOutElastic' );
What happens visually upon triggering this is this: - HTML content changes - text shrinks - text enlarges I think what is happening is that the first animation is suppose to span 500 (miliseconds?) but jQuery doesn't pause for that, it just starts the animating and goes immediate to the second event which is to change the text. In otherwords, I think it's triggering correctly, it's just not producing the visual effect I want. Is the solution to put a pause of some sort between the first two events? If so, what's the proper method?
I haven't used jquery for quite a while and I'm trying to simply alter out the text in a div with an ID of "test" but I'm running into trouble. Code: var mytest = $("#test"); alert(mytest); I'm sure it's because I've selected the div as a whole, but I've tried selecting the first child with no success.
I suppose I should first chain in a "p" selector, then select the first item, but I'm not quite sure how to do it. What I think is my closest attempt is as follows: Code: var mytest = $("#test").("p")[0]; alert(mytest);
I have just written some jQuery code that had to navigate to a parent sibling then 3rd child. My code was $(this).parent().next('ul').children('li').children('span').children('input').attr('checked', 'checked'); Is there any way to optimize this I thought this would work $(this).parent().next('ul').children('li span input').attr('checked', 'checked');
I Use the regular expression to find the html tags present in the input box, It works properly in IE & FF but in chrome it works fine when use first time for an input box but not again, below my code...
I have HTML tags stored in XML. I want to be able to use these HTML elements with Javascript, just as you can with elements in document.body. How can it be done? (And don't try and tell me I should use server-side because I have written it all for Javascript and the project is nearly complete minus this and there are practical reasons for not doing this server-side. After all, anything is possible with Javascript!)
Let me explain:
- I have HTML templates such as this [URL]
- I want javascript to populate these templates then add them to my page
- The only way I know javascript can get this kind of data is by parsing XML
- I want to parse the XML then be able to use the HTML elements just like those in document.body
- As far as I'm aware, XML is the only good way of storing data for javascript. I don't want to store it in javascript variables (too much multiline data with " and '). Nor do I want to build it using document.createElement("div")... etc
As someone not yet with any experience in computer science etc, please ignore my poor terminology! However, I'm not a beginner when it comes to javascript.
Here's the script concerned but I doubt it'll help you understand my problem: [URL]
