I have an array as such:
Code:
var Array = ("1|This Item","2|That Item","1|Here Again",'2|Once More");
I need to be able to count how many elements have the 1 and how many have the 2.I know that I can do the loop
Code:
for (var E in Array) {
(var a, var b) = E.split("|");
if (a == 1) {CtA++;} elsif (a==2) {CtB++;}
}
how can you count something. I have A tags in a div. I want to count specific ones. the list is the order the client made. so I might name or id each a tag. but how can I count those tags. For instance lets say I got an a tag named apple. another named pineapple. I got 8 of each. how can I write jquery code to just look inside this div and count only the a tags named apple.?

So never done this one before so I am having a bit of a time trying to figure this one out.
Say I have a list of LI element and only a few of them have a inline style of display block, the rest have a display of none.
How would I go about looping through and dertmining the number of elements that have a display of block?
for(var m = 0; m < li.style.display.length; i++)
{
alert(m);
};
The above is just crazy but where my mind melts..

I have a long form in a tabbed interface, where I want to count the non blank fields on each tab (the form fields are text and checkbox inputs and multi & single select fields). The counting function is as follows:
// Input argument is a tab object
function
countFieldsOnTab(obj){
var counttext = obj.find('input:text[value!=""]').length;
[Code].....
The counts of text, checkbox and multi-select fields works, but the single select count doesn't return what I want. The default option in single selects is a default where the value is blank "<option value="">-- make a selection -- </option>. These will be found as selected options.
How do I count only those options have have a non-blank selection?
I'm trying to figure out how to make something happen only if there are more than one link inside a div.[code]For now I'm trying to make the little div with the class "cover caption" NOT move when there is only one link in the div.THe reason for this is that I want the whole div to be clickable if there is only one link inside.
View 1 Replies View RelatedWhat is the correct syntax for an nested array where each array element has 3 elements, a number and two text strings?
Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
I'd like to reorganize the third, fourth, fifth and sixth, as well as any
elements thereafter in an array in random order:
var a = new Array('first','second','third','fourth','fifth','s ixth','etc')
In other words, the first, second and third element should remain in
position 0, 1 and 2, while the fourth, fifth and sixth, etc. should appear
in random order.

how to do you add elements to an array? am looking at section dealing
with arrays in JS Bible, can't find how you add to an array.. in the
last few years I've been doing much more Java than JS, am used to Java,
where you can't add elements to an array, but use a Vector instead.. and
it's very easy to add to it (use add() method..) how to you add
elements to an array in JavaScript..
I looked up array obj, don't see method to add to array.
I do a search and get the following in xml:
<user>
<exec>
<entry>Value1</entry>
<entry>Value2</entry>
<entry>Value3</entry>
<entry>Value4</entry>
<exec/>
<user/>
How is the easiest way to find the number of entries in the array and
how can iterate over each value to test if the given value matches
another variable?
I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions.
So far I have this:
function QuantityMWh(form) {
var formchk = document.forms[0]
for (i = 0; i < formchk.elements.length; i++) {
if (formchk.elements[1].value == "" && formchk.elements[2].value == "") {
[Code]....
It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes.
I have this simple code to put elements into an array

View 1 Replies View RelatedI am trying to add the elements in an array together and display the result, I am using a user prompt to obtain the elements for the array, this works fine but when I come to add the elements together and display the result all I get is a row of the elements not their sum. The user inputs are all integers (the program adds the prices of items together so they are all numbers,amounts). If the user enters 10, 15,15,20 the result I get is 10151520 not 60.
