To Check Whether All The Values In An Array Are Identical?
Nov 3, 2010
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.
trying to fix this code up to display the following line at the end:The maximum distance was 6km run on Tue and Fri (the word 'and' not required)So far I have got it to only describe Tue and it stops before it gets to Fri and i have no idea how to get it to write it out in any case.The code also has to work if you comment the lines 22 and 23 where it should display the line The maximum distance was 5km run on Frisorry for simplistic code im very new to javascript!
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.
I am trying to store multiple text values into an array when a check box is checked. for example when row1 checkbox is checked the values row1col1 and row1col2 are stored in an array. note however row1col1 and row1col2 are editable and not readonly. for example:
<table border="1"> <form id="form1" name="form1" method="post" action=""> <tr> <td>row1 <input type="checkbox" name="row1" id="row1" /> (when checked the text fields are editable) </td>
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=[];
function read() { var numbers = new Array(); for (i = 0; i < field.length; i++) numbers[i] = document.test.checkboxName.value; var counter=0;
[Code]...
I want to read the values of the checkboxs and store the vlaues into an array (there are more than 1 checkboxs) the form name is text and the names of the check box = checkboxname
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code: var flag; for (i=0;i<=pdfs.length-1;i++) { flag = 1; for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
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 creating this form that when you tick a checkbox, it adds the value of that checkbox to the running total. Then it displays the Calculation and Running total.
I have to check for several possible values of a variable and I currently do it like so: (SHIP_TYPE == "M" || SHIP_TYPE == "S" || SHIP_TYPE == "X") But this seems overly manual to me. I'm imagining something like the SQL "IN" function: SHIP_TYPE IN ('M','S','X') Does such a thing exist in JavaScript, or do I need to write my own function?
I have checkboxes which are created dynamically depending on the number of records being returned. With each row of the product being displayed along side the check box there is also a value called 'product rate' which is being returned for every product. I have to ensure via javascript that the products which are checked are all of the same 'product rate'. how do i do this? Please help me this is very urgent! I have tried a lot of things but it is not working. I took a hidden value for the product rate which again gets populated everytime the check box is created but i didn';t understand how do i create and check the values of the product rate for the ones which are sele cted?
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." );
When submitting a form, I would like to check the values of some fields first. These fields are dynamically generated by javascript after the page has loaded (that is, a user selected a value from a dropdown between 1 and 10, if 2 is selected, 2 inputs are generated, if 7 is selected, 7 inputs are generated etc). I think I understand that Jquery isn't aware of these items because they were created after the DOM was scanned. Is there any way I can 'refresh' jquery to make it aware of these new items?
From: <input type="text"id="from"value="03.10.2010" size="12" /> do: <input type="text" id="to"value="09.10.2010"size="11" /> <input type="submit" /> --> I tried to do it with function ".val();" but value are keeping steady. It can be done any other jQuery function?
I am very new to JavaScript / JQuery... Need to iterate over the following segment of code and either return an array or single value the e-mail addresses assigned to these labels (these are hardcoded as the check boxes values):
I'm trying to select my textarea only if it is not empty. I have used :empty for this purpose. This works find when you load the page, however if you start typing in it still considers the value as it was when the page loads.
Example. If my textarea is empty when I load the page, it will consider it empty. If I starting typing in, and check if it is empty it still say it is empty.
The same vice versa. If my textarea has text when the page loads, then i clear that data, it still consider it filled not empty.
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.
