Is there an efficient way (ie. not looping through all members and counting) to find out what number an li will get in an ordered list? For example: [code]...
Naturally #first and #second will be 1 and 2, respectively. Without looping though all children of ol and counting, can I determine the number for #first and #second?
I'm just a starter and I'm looking for a function I can't find.
What I want:
I want the row number of the row i clicked of the item list.
For instance I click on third row then I want that var i returns 2. code...
I'm working on a project that requires dynamic manipulation of an ordered list -- adding and removing elements in response to the user pressing buttons. I've run in to some odd behavior. Here's my code:
HTML
<ol id="track-list">
<li>Static Content Here</li>
</ol>
<input type="button" id="add-track" value="Add Track" />
jQuery:
$("#add-track").click(function(){
var listEl = $("<li>Dynamic Content Here</li>");
listEl.hide();
[code]....
Looks pretty straightforward, problem is when I add the new list element it does not prepend it with any number (being part of an ordered list). Now if I remove the hide and fadeIn lines (just append it), it inserts it correctly with a number before it, but I want this to look pretty being jQuery and all...
If i have 4 vars
var one = 29.1
var two = 5.4
var three = 12.4
var four = 15
how can compare all 4 and find the smallest? in this case the result would be two
I would like to create an ordered list in a text area named textfield. Every time someone clicks on a link, I'd like it to add the link name to textfield1 in an ordered list. i.e., A) B) C) D).
Code:
function addMsg(text,element_id) {
document.getElementById(element_id).value += text + '
'; }
HTML Code:
<A HREF="#" onclick="addMsg('You clicked on Link1','textfield'); return false;">Click on Link 1</A>
For example, if you "Click on Link 1" 5 times, it will add this to the text area:
A) You clicked on Link1
B) You clicked on Link1
C) You clicked on Link1
D) You clicked on Link1
E) You clicked on Link1
Then, if you deleted line C), it will automatically relabel to:
A) You clicked on Link1
B) You clicked on Link1
C) You clicked on Link1
D) You clicked on Link1
Then, if you "Click on Link 1" again, the text area will again show
A) You clicked on Link1
B) You clicked on Link1
C) You clicked on Link1
D) You clicked on Link1
E) You clicked on Link1
Is this possible? The reason I want to do it is because I want users to be able to edit the text within the textarea, and copy and paste easily. Otherwise a list box would make more sense. Can't do HTML in a textarea.. though?
I have a string with javascript linebreaks with /n. I want to make a function that will make a text only ordered list (text within a text area... i.e. I don't want to us ol and li)
For example,
Spot1
Spot2
Spot3
would be converted to
A) Spot 1 -
B) Spot 2 -
C) Spot 3 -
So far I think I need to use an array, and replace...
Code:
function AddLabels(element_id) {
x=document.getElementById(element_id).value;
countlinebreaksstr=x
try {
return((countlinebreaksstr.match(/[^
]*
[^
]*/gi).length));
} catch(e) {
return 0;
}
var myArray = [A,B,C,D,E,F,G,H];
var i=0;
for (i=0;i<=10;i++)
{
}
Is is possible to make an ordered list with an onclick display prompt show the number item of the list? What I mean is like, say I have 29 items, but I click on item 15, is possible to make the prompt show the number 15, or the correct number for any item I pick?

View 10 Replies View RelatedWhat I want to do it multiple the quantity ordered by the kind of shipping selected in my <select> list.
I'm pretty sure that what I've got to do is establishe a quantity ordered variable like this var qty = form["Q" + i].value And then multiply that qty variable by the ShippingCost. But no mater where I stick this var statement it always either stops the script cold or comes up as a black or undefined value.
<script type="text/javascript">
/* <![CDATA[ */
var ListCount = 5[code].....
In attempting to modify a script of a menu, that I wanted to add the ability to have sub menus, I first wanted to find out if an ordered list element, contained a secondary unordered list and what their names are so I could out put the items to the console.
Here is the test list:
<div class="nav-wrap">
<ul class="group" id="example-one">
<li class="current_page_item"><a href="#">Home</a></li>
[code]....
1. The script finds all the headings in html (<h1></h1>).
2. Creates a list of titles of these headers.
3. The list has a specific css and the maximum length of text.
4.Each name from the listhas (<a href="">name</a>) is a link to the title.
$(document).ready(function() {
$('h1');
$('.left li').addClass('button');
[code]....
I have not been able to find a list of the functions in Jquery...probably not Googling for the correct phrase.
View 1 Replies View Relatedi have a couple of elements on my web page, that i want to manipulate in one loop.
jQuery.each($(".specificClass"), function(i) {
// do something
}
Within that loop i have to check what type of element that very one is e.g. a <div> or a <span> or an <img> or a <input type="button"> or something else.I managed to isolate some of them, the easiest was the button where i checked the following:
if ($("selector").is(":button")) {
// do something
}
In the jQuery API 1.3.2 there are some more useful Forms Filters like :input, :text, :checkbox etc. What i really miss is something for a drop down list. I would have expected that there is something like
if ($("selector").is(":select")) {
// do something
}
but i could not find it.It would also be great to have something to check if the element is an image. I have read that there exist such a check, but that is for images that are input-images within a form. I am longing for a simple check for an image somewhere in the web page.
if ( !isNullOrEmpty($("selector").attr("src"))) { // --- image ---
// do something
}

I am working on my assignment: The assignment is: The process of finding the largest value (i.e., the maximum of a group of values) is used frequently computer applications. Write a Javascript program that input a series of 10 single digit numbers as characters, determines the largest of the number and output XHTML text that displays the largest number. Your program should use 3 variables as follows:
a.) COUNTER: A counter to count to 10 (i.e. to keep track of how many number have been input and to determine when all 10 number have been processed). b.) NUMBER: The current digit input to the program.
c.) LARGEST: The largest number found so far.

When I find a record such as this in a textarea:
[Code]....
There will be from 1 to 4 Pts, if one is missing there will not be a next one. My problem is I replace the first occurrence of any number I find and for certain factors (2 in this case) it could change an already converted number and leave other fields in the record alone. I could split the line on commas to change the first number I find but can't be certain if there are no other commas elsewhere on the line.
How to find out the previously selected option value in a select list?

View 9 Replies View RelatedI'm loading another html file full of list items. What I would like to do is hide() the content right after it's loaded, and then fadeIn(0 each individual list item one at a time.
The problem is, it's loading all the list items at once. I don't know what to do. I could code the chain manually, but only if I knew the number of items in the list would never change. I'd really rather set it up to fadeIn any number of items dynamically.
Here's my code, which I know doesn't work, but maybe you could see what I am trying to do:
function loadContent(location) {
$('#content').load("assets/content/"+ location).hide();
var x = $('li#content').size();

View 3 Replies View RelatedI want to build a dynamic list of items with jquery but am unsure how to add an index number to each of the items i create so that i can reference them to edit or delete them for example. So far, I have the following which just creates the items and appends or prepends them to the element depending on whether one item exists already. I just need a way of adding an attribute so I can then reference the current item when clicked and remove it. What would be the simplest method to use?
//create list items
if ($('.mylistitem').length) {
$('.myList-box').prepend('<div class="mylistitem"><div class="mylistitem-image"><img width="30" height="40" src="[URL]"/></div><div class="mylistitem-title">' + title + '</div><div class="mylistitem-options"><a href="javascript:removetitle();">Delete From List</a></div>');

While using jQuery, I found that I needed to know how many records were returned and also if the result set returned was empty. After searching the jQuery documentation I couldn't find any property or method that returned this value, so I've added that functionality
myself and wanted to share it with the group.
1) Determine the number of records returned: I wanted to show the user how many results were returned after they start typing into the autocomplete field similar to how Google indicates the number of results found when you start typing in the search box. At first I thought the max parameter in the function formatItem returned this value. However, it returns the max option that you set it to. So if your query returns 100 records and you set max to 25, it'll obviously return 25 (not what I wanted).So after trying various things, I looked at the jQuery code and simply added the number of records returned by the database to the formateItem function. In the fillList() function around line 660 I added the data.length parameter:
var formatted = options.formatItem(data[i].data, i+1, max, data [i].value, term, data.length);And in my autocomplete code, I added the parameter to the end of theparam list:formatItem: function(data, i, total, value, searchTerm, totalResults)So now whenever a new search is preformed, I get back the number ofsearch result from the database.
2) Determine if a result set returned was empty I wanted to update a <div> with a message like "no records found" whenever the query yielded no results. Again, after searching the jQuery documentation, I couldn't find any property or method that would indicate this so I added it to the code. In the request function after the line var data = cache.load(term); I added the following:
if (!data) {
options.isEmpty(0);
} else {
