Accessing The Array Index Of An Input Field?
Oct 20, 2011
I 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 =
[Code].....
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 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 know that we can split() a string into an array, if we have a string in an input field like this, "javascript rocks"
what if there is only one keyword in the input field?
for instance, it is only a word - "javascript"?

Here is my dilemma:I am preparing a mock website that basically sells crates of juice.I have 10 different types of juice available to my customers.If they buy 5 crates, then they get a discount of 12.5%. How on earth do I set up an array for my various juices, with an input field for the amount of crates they want?i.e. Orange Juice(0 shows in the input field until customer enters amount required).
Once they have made their selection, I would like to show it on screen, like an Invoice or something, or perhaps just a message that says you have ordered this, this is what it costs, with 12.5% discount if 5 crates have been ordered.

( text )
var v = 'I am a string'alert(v);alert(v[0]);
Works fine in Mozilla but not in IE. v[0] in IE is 'undefined'
I've tried declaring v as new String(); and the problem still happens.
I've done some googling for this issue, but can't find anything on it.

I have an array like this:
I need to compare these array items to my site div id's and make an onblur functionality that changes the input field value.
It does not change the selected input field value(this.value). And it only alerts when blurring from the input field that is first in the array(id1). If i click to the input field id="id2" it does not alarm?

I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.

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

<script type="text/javascript">
function popsizes(colorcode) {
var BLK=new Array();
BLK = ["2XL","3XL","4XL","5XL","LG","MD","SM","XL","XS"];
elem = document.getElementById("selcolor");
for (i=0; i<elem.options.length; i++){
sizelist = colorcode[i];
document.getElementById("selsize").options[i] = new Option(sizelist);
}}
</script>
In an event, i'm passing in "BLK" as the colorcode param. This is creating my selsize select box with B, L, K, and undefined options until the for loop finishes. ie, its taking the passed in colorcode as a literal string, instead of referencing the array. Anyone have a pointer as to how i can access the arry, instead of the literal string?

I can't alert the history array of the index page or use that arrays indexOf to read and write it to go back to predetermend conditional index of that array? If I could alert the history array and read the array elements then I might be able to write and go to one of the history array elements specificaly? So I might be able to use window onload to create an array that stores the classname of a div every time the divs classname is changed then go back in page history to the classname specified? code...

I have a string variable coming from a database, like 2,3,1,4,5,6,7.
The string is gotten from: <%=(Recordset2.Fields.Item("neworder").Value)%>.
And, have the following:
Is it possible to use the string variable to replace the index numbers so there will be a new position of the array?
