JQuery :: Why Isn't Passing A String To The Index() Method More Like Find() Or Filter()

Aug 23, 2010

Given the following HTML:

<ul>
<li class="">1</li>
<li>2</li>
<li>3</li>

[Code].....

Unfortunately that doesn't work. I understand that the index() isdocumentation (though confusing) correctly tells you that the above code doesn't work. Maybe I'm just weird, but I feel that the way .index() is implemented for string arguments is very counter intuitive. I have an expectation that .index() is similar to indexOf() in javascript.

Nov 12, 2010

What's the best simple way to filter elements by their index similar to the nth-of-type equation an+b , regardless of parent and node type? Something like...

$("input").filter(":nth-of-set(3n+1)")

... to filter every third input element (3n) starting with the first one (+1).

JQuery :: Get Execution Index Of Method?

Dec 14, 2009

I'm not sure if the subject describes what I'm asking very well, but it's the best I can think of. In this example:

$(".nav a").bind("click", function(event, i) {
});

Is there a way to get the index of the a you clicked passed into the handler? Like if I clicked the second A i would = 2.Same question for any jquery method actually. Since they all work off of collections I'd like to be able to get the index on anything.

Find Row Index By Clicking On A Link In The Row

Oct 21, 2011

I am dynamically adding text boxes within a table and I want to be able to dynamically remove them as well. I have this part of the code figured out.

With each text box that I add, I also add a link in the same row, but different cell that will be a "remove" link. Im having trouble finding the index of that row by clicking on a link.

I can find the index by clicking on the row(tr) but I can't seem to figure out how to find the index by clicking on the link inside of the row.

Here is my code:

Creates the link dynamically in the 4th cell:

Code:

Remove Row Code:

Code:

Find Row Index Code:

Code:

I beleive the problem is in the rows[i].onlick part, since I'm not techinically clicking on a row, Im clicking on the link. I have tried changing the rows variable to:

Code:

But that doesn't work.

Find Real Height Of Content In DIV With Relative Z-Index Value?

May 13, 2011

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?

JQuery :: .submit() Passing No Values In Chrome When Method Is Post

Feb 5, 2010

I have tried to search for the answer to this, but came up empty. I am writing a form checker (and submit) in jQuery, and am testing with Chrome. Once I do my validation, if all is ok, I simply submit the form using...

$("form#courseForm").submit();
and here is my form tag.
<form name="courseForm" id="courseForm" action="courseDetail.asp" method="post">

In IE it works fine with either POST or GET methods in the form tag, but in Chrome it will only work with GET.When I try to use POST, the form does submit, but I don't get any data sent to the page at all. The only thing I am doing different than usual, is the form does not have a submit button. I am using a "button" tag and using jQuery to capture the click event. <button type='button' name='courseSubmit' class='blueButton'>Save Changes</button> why the POST isn't sending the data in Chrome? Simple workaround is to change it to a GET and it will always work, but I see that as a bandaid fix, and not really a solution to the problem.

JQuery :: Why Does String Replace() Not Work For The Results Of The Html() Method

Aug 13, 2011

I've seen an other post talking about not being able to perform a .html().replace() also, but no one replied.

[URL]

Why is this? I ran into the same problem and from what I was seeing, the replace() was only replacing the very first match. My work around was pretty simple, I just keep running replace() until it was done, but I'm dumbfounded as to why this would need to be done.

while (newLastRow.html().indexOf(settings.placeholder) > -1){
newLastRow.html(newLastRow.html().replace(settings.placeholder, curTotal)); }

As with the other post, I'm dynamically adding html to the page using a template, where the replace() method is updating the IDs of the fields when adding a new instance.

What's special about the value returned by the html() method? Is there a different preferred way to do this?
