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.
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).Â
This is my very first post! so please be kind Ok, i am very novice to jQuery. But what i am trying to do is use the jQuery attribute selector to select an input with a specific name. I can select an input of name type fine by doing the folowing:
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.
i came across this plugin [URL] and i thought that it be nice if i could manipulate the content recieved by making the hyperlinks linkable: it be something like select all that start with "http://" and wrap it with an anchor linking to this hyperlink but i have no idea how to do this through jquery
If I had 12 element divs, how could I make a toggle function that work for all of them?
<div id = "element1"> <div class="question">1. Who wrote the book James and the Giant Peach?</div> <div class="answer"><img src="images/cover.gif" class="top"/><p>Ronald Dahl</p></div> </div>
I have an array of integersI like to retrieve the max number and index of max number from that array without using Math.Max() function..Presently in this below code, I have 4 dynamic values, end user will be select degree from combo box, entering the values semester, Max marks and Obtained marks as numeric values. Once entered dynamic rows will be created and it also calculate the percentage by the formula (om/mm)*100 for each row on clicking Sum and it also creates new column¦I needed to have code when the degree changes only.. it should calculate the sum of all max.marks and Obtained marks of each semester and then calculate percentage by above formula¦ and also new column should not be createdsort with max markswhat is the easiest way...
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:
I have an array "arr" that is an array of objects. Each object has the same 7 properties.I want to find the index of the object with a property that matches a certain value x in the array arr. The array has hash tables associated with it.
arr [ obj [ i ] . property1 + "_" + obj [ i ] . property2 ] = arr [ i ] ;
so whats the index of the object where .property1 = x ?

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?
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.
If I know that apple exists in above list.How to get index of whole string from the list.Like apple should have the index 1, ball should have 2 and so on.
Is it possible to create a function that will find a class name or id name and then assign that name as variable string?
For example, my body has a class name:
<body class="Sunday">
I need to have a function (using jquery or just regular javascript) that will determine that class name and then assign it to a variable named bodyClass, so that bodyClass="Sunday".
I'm trying to learn jQuery and am currently attempting to clone a div and then find and replace part of a string. The cloning part works, but I can't seem to get it to alter the text... In the html below, I'm trying to find all instances of issue-0, issue_0, or issue[0] (whether it's a name or an ID) and replace it with issue-1, issue_1, or issue[1] (depending on the character found after "issue")
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?
I have this image gallery in which clients should be able to determine the order in which their images are shown. The sortable part works. Then I want to pass the new order to the next page called act_writeneworder.cfm (i am using coldfusion) I just started with jQuery and it is driving me nuts:-) Each time I think I am having it well i am testing and the variable passed through gives an empty string. My code:
I'm just trying to find the best method of updating a running total of the value of list boxes. I basically have 6 items and I want a drop down box listing quantities. when a number is selected I want a total to update beneath. I'm not sure I can do this in PHP without reloading the page. Do i need to use Java script? if so I'm a total newbie can someone point me in the right direction?
