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 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 want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"]; function create(){ var array=[];
I have a value, j[i] , which Ineed to do the following with:1) split with / to make an array2) Return the last valueFor example:Continent/country/State/City..and it would return "City", and with:Continent/country/State..it would return "State"Can anyone point me in the right direction?In Perl, I would just do:
my @tmp = split ///, $val; my $last_val = $tmp[$#tmp];
How do I search through an array looking for an inputted entry? Ihave this so far. Also need it to display where the object was found. var states = new Array(); var i; i=0;
So, I am attempting to select a random entry from an array, and then make it so that particular entry will not be selected again until every entry has been selected. Basically, I don't want to see any of the same entries, until all of the entries in the array have been selected.
So if this were my array....
keywords = [ "ppc", "games",
[Code]....
since meta was selected a second time before everything had been selected once.
I would like to see something more like
meta, advertise, gaming,ppc, welcome, home, games, advertise, ppc, since this did not select any entry multiple times before every entry had been randomly selected.( the second loop started at the second "advertise" in case you didn't catch the differences.
But as you can see from the code that I have posted above, I do not know how to do this. I have seen examples where the entries that were randomly selected, were actually deleted from the array entirely but this is not what I want to do. I just want every entry to be selected once, and then for the process to be restarted.
I am trying to accomplish a fairly basic task with javascript > my lack of Js knowledge has meant i have hit something of a roadblock.I need the a function to take an array from a form, remove the parsed variable from it and repost the form with the new array.This is what I have so far...
<script language="javascript"> function remove(SID) { var speakers = document.form_name.elements["SID[]"];
I have a textbox on one of my forms that is used to accept a time from the user. I need to write this value to a database to trigger an event later on.
What I'd like to know is...
Are there any functions in javascript that can convert different time formats to a known format (24 hour clock)... 5pm -> 17:00 or 5:00 to 05:00, etc. ???
Assuming that I get the input into a 24 hour format, how can I create a full time/date variable with todays date and the users entered time?
Finally, if the entered time is earlier than the current time, how can I create the above date/time combination using tomorrows date?
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
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 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 ?

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 want to get index number of form element array. where I want to put name in the front of code input box. Can any body tell me that how is possible. code...
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 want to get index number of form element array. where I want to put name in the front of code input box. Can any body tell me that how is possible.My code is as follow:
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?
There is a missing part on my program, it is when you input less than or equal to 65 and greater than 100, a prompt will appear and say "Invalid Entry" and ask you to Input again an entry until you enter a valid entry. For example on Prelim Grade, I input 50, a prompt must appear to say "Invalid Entry" and ask me to input again another entry. Another is how will I terminate the program? When I input an invalid or a valid entry, it is continuing to ask me to input again an entry.Here is my code
How to get the index number of getElementsByTagName("input") array on clicked field? i.e. when i clicked a field name "f03" of first record, i want to print(alert msg) the index value as 0, for second record 1 respectively.for that i want to write javascript for onclick event.
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.
