I'm writing a blackjack game for class,it generates two random numbers that select from a switch statement that creates a string file name of a card e.g "AceDiamonds.gif", it then fills an array deck[] with these strings,I want to fill the array with the full deck of 52 cards,and not have any duplicates, how do I check the array for an existing element remove it and replace with another card not in the deck??
Im trying to add to each element within an array. In this program I have an existing array which is called aScores. I have copied its contents into another array called aScores using slice. Now Im trying to add the value of variable called classCurve to each element of aCurve using a for loop (see under the Curve Scores functrion section). However, it does not seem to add the two together(e.g 78 + 5).
I need to check for a particular window which I opened as a popup, already exists, before I try to open the same again. I achieved that with the following code. So this is fine.
var myWin = null; function openPopup(aURL){ if (( myWin==null) || myWin.closed) { myWin = open(aURL,"myWin"); }
/* Window is already opn, thus maps the url to the same window and give focus */ else { myWin.location = aURL; myWin.focus(); } }
Now my problem is I need to do a similar check for a page thats been href to the top.location top.location=aURL;
In this situation if this same code runs again, i need to check if this window is already open, and if so not to open it. Can it be done in a similar way like the above.
I'm trying to add a onclick event that will sort an two dimensional array to a existing element that I can not change.

I'm working a bunch of pre existing code on a CMS. Just after a quick fix. Doing a show/hide thing on a particular div somewhere on the page depending if a checkbox is ticked or not.Currently there is 3 checkboxes that are dynamically added through the CMS. Here's simplified version of the form:
I'm trying to grab values from a set of arrays based on the value returned by my select box.
**Caveat - this is not an area I have any real experience with**
My arrays look like:
Code JavaScript:
I then need to test for each, then associate with one of my fees arrays, then grab each of the values in the array and write those values to elements within my page.
I'm then doing this to evaluate for each degree
Code JavaScript:
I need to first figure out how best to import all of these 60+ arrays and then in each of my conditions pull out each value and write to my page.
There is a unique 1 to 1 relationship between each degree and array so I can't consolidate as the values for each degree differ slightly.
I am currently trying to check using javascript whether a php array contains a variable, and if it does then display a message.I have written the following code...
<?php //php which sets users array to the results of the sql $selectquery = "SELECT Username FROM User";
It's to allow users to create thier own descriptions, and the input is displayed automatically using innerHTML. This part of the function checks if the HTML tags are allowed through, I've got this far...
I need to verify that the email address is not a free account. I will have an array that contains a list of free email providers. ie. gmail yahoo hotmail.I want to compare this list to what the user entered. and if there email address contains one of the values from the array then return false. I am a php dev so excuse the crude code.
Code:
var freeEmail=new Array("gmail","yahoo","hotmail"); if (form.email_address.value (contain a value from freeEmail) { alert( "Please no free email accounts." );
I am working with a checkbox array where the key is already set. So instead of being able to use name="name[]", I need to use name="name[0]" etc.. I would like a button or a checkbox to select all in the array(name).
The main reason for this is the nature of the checkbox. If a checkbox is not selected then it is completely skipped when looping through the array. To overcome this I added a hidden field of the same name which will assign a value even if the checkbox is not selected. Then the problem of using name[] arises.
The form is populated with hundreds of entries using PHP so I am looking for a way to loop through them all.
Here's a tiny snippet of HTML of how my form is set up.
I'm looking for some guidance on a part of some coding practice I'm stuck on!
I've created a shopping cart using javascript, the items save to the arrays etc and it all works fine. If the user adds the same product again to the cart the quantity is added onto the previous quantity that is already in the cart.
To check if the item is already in the cart I've ued the below code, but what it does is update the quantity for the first cart, and when it updates the quantity for the second item it updates the quantity but keeps adding the same product to the cart in seperate elements of the array as well (if that makes sense?
here are the two functions used [code]...
It may jsut be a simple mistake I've made but it's been bugging me a lot and I can't seem to fix it.
I want to check whether all the values in an array are identical using javascript.Does javascript support this?If so please provide me the js statement.I know it can be done with conditional statements but I want to know the efficient way to implement this.
Code: var strUsersName = new Array("John","Mac","George");
I want to check, if the particular loggedin user for example Mac is available in the array list declared.How to check in a efficient way, if the particular user loggedin is available within the array declared.I tried this, but I am not sure, if it is correct:
Code: var strUsersName = new Array("John","Mac","George"); var L=strUsersName.length;
So that I can pass multiple checkbox values to my PHP processing script as an array I added the square brackets to my form's checkbox input element's name, like this: <input type="checkbox" name="checkGroup[]" value="'.$rowIDs.'" /> Because it has to match, I updated the input element I use to check/uncheck all the checkboxes so that it now looks like this: <input type="checkbox" name="all" onClick="checkAll(document.ResIDsDates.checkGroup[],this)" />
When I manually select multiple checkboxes I can successfully pass any number of checkbox values through the POST array to my process script...but my Check/Uncheck All box has ceased working -- adding the square brackets to the checkbox input's name disabled it.
I tried playing with the ASCII equivalents to the brackets, but no go. Is there a way to retain the array functionality and pass multiple checkbox values to the script AND enable the Check/Uncheck All box?
What is the fastest way to check whether a specific UserID exists in the array using Jquery or Javascript because gAllMedicalFilesClaimantsArray has got 8000 records?
I want to validate a form. In the form is a text field named 'extra[]' where the user inputs a number. The number is what I want to validate.
However, the 'extra[]' field is dynamic and does not always appear in the form.
If it appears, there may be only 1 occurrence of it which means it's then not an array but there may also be multiple occurrences of it.
I have a script that validates (and work as it should) if the 'extra[]' field occurs multiple times and is thereby an array, but I can't figure out how to validate the 'extra[]' if there is only 1 and to not throw an error if it's not there at all. Code:
I have a form where I click a button and it duplicates the inputs thus now having X of the same inputs. The input name looks like so: <select id="select" name="cs_quantity[]"> Is there a way I can check the all values of the quantity before submitting the form? I want to make sure they've chosen a quantity other than 0.
Im trying to pass fields to a javascript function that will check the value of each field and it its empty then it will turn the field color red which is what its doing at the moment, but i want to be able to use this function globaly through out my project, so is there a way of not saying how many fields go in to that array, it will just deal with the amount of fields it gets passed?
my code always call when i click "dt a" but i dont want like this. i want like that if i click element visible don't do anything. my code call when i click element "dt a" unvisible.
I am dynamically creating CheckBoxes DropDoenlist with certain set of values of not all of then are created any time.But in Script i want to get sure whether that element has been created or not. So how can i check for radio button list and dropdown list.Below is the code for my dynamic list creation:
