How do I use array.push to add an object with a custom index in an array?I have this script but it doesnt work. Chrome's Javascript console is not outputting errors
var tempList = new Array();
$('#add').click(function(){
var split = $('#itemid').val().split('_');[code].....
I have a 2d array that I created like such:
var images = new Array(50);
for(var i=0;i<=51;i++)
{
images[i]=new Array(2);
}
Now I would like to push values into this array, but I can't get the proper syntax to work. How would I for example convert these statements:
JavaScript Code:
images[1][0]='a'
images[1][1]='b'
images[1][2]='c'
into a push statement (regardless of position pushed into array)?
I have an array question. I think that you'll have to run the script in your browser to see the results. The below array separates ages but I get stuck on how it does this when I get to line 6 and beyond. Line six reads "if (tempAge <21) minors.push(tempAge);"
I only understand that the pop method takes the number 19 off of the ages array. So if this is so then I think that line 6 reads that if 19 is equal to or less than 21 do something, but I don't know what it does after that, please help me understand how it works.
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].....
Let's say i have two arrays:
var array1 = ["1","2","3"];
var finalArray = [];
and I want to dump the values of array1 into finalArray several times to end up with the value of finalArray being:
"1","2","3","1","2","3","1","2","3"
What would be the easiest way to dump the values into the other without making it multidimensional?
I found this code on Internet:
<script type="text/javascript">
Array.prototype.push = function() {
var n = this.length >>> 0;
for (var i = 0; i < arguments.length; i++) {
this[n] = arguments[i];
n = n + 1 >>> 0;
}
this.length = n;
return n;
};
</script>
Question 1: How to call this function?
Question 2: When I delete >>> 0, what I lose? ( >>>0 ı sildiğim zaman, ne kaybederim?)
I am basically just practicing with javascript (Just started a few days ago) and wanted to create an array that pretty much checked a form for errors, listed errors, then spewed them out in the end. I am sure there is source code for something like this, but I wanted to just do this out of practice, as I have done this before in PHP. I am basically making a function with a bunch of if statements and if any of them pop up I try to PUSH a string into the array. Now, it has worked, somewhat and sometimes. But then it just plain stopped working. I played with the code for a while, placing alerts in parts of the function and found that it WAS the push code that stopped it from running completely.

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.
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 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 am getting the correct result in "title".I have tried setting "test[0]=title;" with an if on the first pass and then using ".push" but to no good effect.if there is a better way to achieve my objective or is this a reasonable solution

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 2 Replies View RelatedI have a form with multiple input fields and I'm trying to identify the specific input field that is in focus so that I can display a relevant status bar message.
I have a message array with various entries in it and I'm calling a showStatus() function with an onfocus function from the form itself e.g.
The code in the input form =
<input type="text" name="first" size="31" maxlength="20" class="entry" onfocus="showStatus()"/>
The showStatus() function so far is =

I'd like to access the array variable of the item that is in focus not only for the message but also for an onblur function to validate input.
I have the following array that contain the people who are on off on certain time:
var all = [
["1234", "Jim", "2011-10-23 00:00:00", "2011-10-25 07:00:00"],
["1235", "Jack", "2011-10-21 00:00:00", "2011-10-21 08:00:00"],
["1236", "Jane", "2011-10-11 00:00:00", "2011-10-11 00:30:00"],
["1237", "June", "2011-10-20 00:00:00", "2011-10-20 12:00:00"],
["1238", "Jill", "2011-10-14 00:00:00", "2011-10-14 11:00:00"],
["1239", "John", "2011-10-16 00:00:00", "2011-10-16 10:30:00"],
["1240", "Jacab", "2011-10-19 00:00:00", "2011-10-20 08:30:00"]
];
The above array, I wish to use javascript to insert into the FullCalendar [URL]. I notice that the only way seems to be using the FullCalendar array style (or structure) as follows:
$('#calendar').fullCalendar({
events: [{
title : 'event1',
start : '2010-01-01'
},
{
title : 'event2',
start : '2010-01-05',
end : '2010-01-07'
},
{
title : 'event3',
start : '2010-01-09 12:30:00',
allDay : false // will make the time show
}]});
So, the question is: How do I insert my array to match with the FullCalendar array? : cause FullCalendar array had a different array structure from my array - and I don't think so that I can write in this way:
$('#calendar').fullCalendar({
events:all
});

I have created a class array (or variable that contains an array) and am trying to add an element to the array when a new Element object is created. Thus, the line of code to add a new element to the array is within the Element object's constructor function. However, the browser just gives me an error "object expected on line 9", the line of code trying to add an element to the array.
Are arrays not functional within objects? Or, is it that the array is made as a class variable?
Code:
function Element() {
// INSTANCE VARIABLES
this.name = "newElement" + Element.total_elements_created; // GIVE UNIQUE NAME
// INITIALIZATIONS
Element.element_count ++; // INCREASE TOTAL NUMBER OF ELEMENTS EXISTING

I have a form element that looks like this:
<input type="text" onchange=doSomething(this)>
and a function:
function doSomething(theField){
}
I know that within the function I can access properties of the field (e.g. theField.name and theField.value). But how do I access theField's index number in the form's elements[] array -- from the "this" reference that was passed to the function? I.E. if this field is elements[3], how can I get at that 3?
is it possible to access the index of the json data array in the current iteration and use it in a template?
