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 want to set predefined URLs and display some HTML when the URLs are loaded on the page where the code is. Let me give you an example implementation.With forum software, you get one template file that makes up the view forum page. I want to display a piece of code ONLY when someone visits a particular forum. So, I want them to see it when they visit:
I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?
Code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
[code]....
I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.Next, check if the textbox matches the pattern (which is to check if it has the skeleton of a phone number). If it is, show an alert message that it is alright. Else, show that it does not match.
is there any way one can test if an element matches a jQuery selector? I'm not trying to locate elements, just test for match.
More specifically, when using event delegation and a common callback function for multiple events, is there a way to check the event's currentTarget against a selector?
In the following example, how can I check if the currentTarget is the LI node with class "item2"?
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 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";
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.
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??
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:
In IE (tested 7 and 8), $('td[colspan]') seems to match every single td. In Firefox and Safari, though, it (correctly) returns only those which do have a colspan attribute. Here is a simple test:
I have a form with two fields: shape and color. where people select a shape an image of the shape appears, and a default color image appears.When they select a color, it changes the color image. But if they go back and change the shape, I don't want it to turn the color back into the default image. But I don't know how to do this script.Here's the function I have, but I don't know how to write it:
function changecolor(picName,imgName) { var idx = filepath.pic4 if (idx = "/images/leaf_shapes/entire/transparent1.gif")
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?
how to make a function that changes a specific image on a page when the user chooses from a menu, but only if the src name matches "transparent.gif"
With numerous other scripts, I've cornered myself into this as the only solution for now to what I'm trying to do. But the script is not working. Here it is:
Code:
<script> function changecolor(picName,imgName) { var leafcolor = document.getElementById('pic4').src;
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 was wondering if there is a "selector construct" that matches an element having more than one child. So I'm looking for a solution that doesn't need an if statement such as;
if($('ul').children().size()>1) { //do this }
[Code]....
But I'm looking for a selector that already looks for these conditions. Kind of like how :has() works but then a check for more than one child.
