Code: function initArray() {
this.length = initArray.arguments.length;
for (var i = 0; i < this.length; i++) {[code].....
For the above piece of code, does the function 'function initArray()' just predefine the array that is written right after so that it's first array index starts at 1 instead of 0?
I wish to access several pictures on my page by defining them as an array. This way I can either loop through them or access them by array index.
What I am really doing is writing my own picture gallery and slide show. The reason I am doing this is so that I can have my web page look exactly the way I want. In addition, it is an excellent way to learn Javascript.
I have the below array called "results". When I loop through all document elements I would like to check "field_name" against the "results" array and see if it exists and what index number it is at??
// Split the comma delimited response into an array
results = result.split("~");
//Loop through array and populate fields[code].....
I would like to have an array and define which element goes to what key. Something like this:
Code:
var test = [][];
test[0][0] = "foo";
test[0][1] = "bar";
However I am wondering if its possible to write it in one statement? Something like this:
Code:
var test[0] = [
[0] => "foo",
[1] => "bar"
];
The code up doesn't work of course.
What's the difference between defining a variable with 'var' before, versus defining without it?[code]

How to avoid the execution of a function at the time of defining.
Here i am giving the details.
I am creating the following div container through DOM.
<div id="content">
<a href="#" onclick="displayDiv('content')" Click</a>
</div>
The Code is:
var category_list = document.getElementById('category_list');
var dom_div = document.createElement('div');
dom_div.id = 'content'
var dom_link = document.createElement('a');
dom_link.href ='#'
dom_link.onclick = displayDiv();
val = document.createTextNode('Click');
dom_link.appendChild(val);
dom_div.appendChild(dom_link);
category_list.appendChild(dom_div);
The displayDiv Funcion
function displayDiv()
{
dv = document.getElementById('content'); //Here is the error.
}
The Problem is when the following script:
dom_link.onclick = displayDiv('content');
is executed it is calling the function displayDiv(name)
Here we have the code
document.getElementById('content');
which throws the error.
The reason is the div container is not yet created.
What I need is the function should be called only on the click event. It should not be called while I define it to the Click Event. (ie it should not be called at the time of defining)
How to achieve this.
1.In ZZZ.html i have a long list of text items formated like this:
<div="part1">
<span > <h3 >AAA</h3><h4>BBB</h4></span>
<span > <h3 >CCC</h3><h4>DDD</h4></span>
[code]....
In another document i made some buttons to change slideshow content by loading sections id to
<div id="cyc" class="slide"></div>
using function:
$('#cyc').load("ZZZ.html #part1");
etc...
Text loaded, but the slideshow didn`t work
2.How can i loop specific range of slides ( and make it modifiable with some "range selector" in browser) ?
3.Is it possible to trigger some event on the desired slide number ?for example:
on slide 3 - play sound
on slide 6 - display message
on slide 15 - go through slides 10-15 four times

I'm refering to an entry in an array by it's string key, as in
foo["bar"]. Is there a way to get the numeric index of that array
without iterating through the entire array?
What I need to do is find the "next" or "previous" entry in the array,
but the keys are strings, instead of numerical indeces.
I have an array in which each element is a long string of various values separated by a particular character.I want to be able to search the array using the first value of each element to get the index.I cannot see how to do this so I have started to create a function for this.I want to take the original array, split out the value into another array and search the new array.I can then use the index returned to retrieve the full string from the original array.However I am having a problem when trying to set the new array and I do not know enough JS to understand what is going wrong.Here is the code:
Code:
<script type="text/javascript">
var test= new array();[code].......

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 ?

View 3 Replies View RelatedI have two textbox columnsof equal length they are accessed in the following manner:
taborder 1
taborder 2 taborder 3 taborder 4 taborder 5 taborder 6 taborder 7 taborder 8
When I leave the first textbox (taborder 1), I need to check and see if the textbox contains avalue. If it does, then I need to check and see if the second textbox (taborder 2)contains a value. If it doesNOT, then I need to loadthe second textboxwith "100" and highlight (select) the text. I am adding a blur event to all the column one textboxes as they all contain"rawCount" in the id. Here is my blur event code:
$(document).ready(function(){
$('input[id*=rawCount]').bind('blur', function (event) {
// Code to go here
});
});
What I am trying to do isadd thecode tocheck and update thecolumn two textbox in the corresponding row (same index)to the blur event of the column one textboxes without having to loop the array each time to find the current textbox array position. Since it is adding the blur event, it has to be possible.
