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[]"];
[code]....
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?
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];
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 created an array, whose entries looks like this:
[41, "The bird flew into it's cage"]
[33, "He drew fire from Joe"]
[33, "Roger asked her her name"]
[code]....
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;
states[0] = "Alabama";
states[1] = "Alaska";
states[2] = "Arizona";
states[3] = "Arkansas";
states[4] = "California";
states[5] = "Colorado";
states[6] = "Connecticut";
states[7] = "Delaware";
states[8] = "Florida";
states[9] = "Georgia";
states[10] = "Hawaii";
states[11] = "Idaho";
states[12] = "Illinois";
states[13] = "Indiana";
states[14] = "Iowa";
states[15] = "Kansas";
states[16] = "Kentucky";
states[17] = "Louisiana";
states[18] = "Maine";
states[19] = "Maryland";
states[20] = "Massachusetts";
states[21] = "Michigan";
states[22] = "Minnesota";
states[23] = "Mississippi";
states[24] = "Missouri";
states[25] = "Montana";
states[26] = "Nebraska";
states[27] = "Nevada";
states[28] = "New Hampshire";
states[29] = "New Jersey";
states[30] = "New Mexico";
states[31] = "New York";
states[32] = "North Carolina";
states[33] = "North Dakota";
states[34] = "Ohio";
states[35] = "Oklahoma";
states[36] = "Oregon";
states[37] = "Pennsylvania";
states[38] = "Rhode Island";
states[39] = "South Carolina";
states[40] = "South Dakota";
states[41] = "Tennessee";
states[42] = "Texas";
states[43] = "Utah";
states[44] = "Vermont";
states[45] = "Virginia";
states[46] = "Washington";
states[47] = "West Virginia";
states[48] = "Wisconsin";
states[49] = "Wyoming";
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 have a form with firstname in one field and lastname is another field. I need to manipulate the entry so if someone enters Joe for the firstname and Smith for the second name it will be changed to Smith,Joe. Here is my attempt but it just switched the fields and didnt manipulate how I wanted it:
var name = "Joe Smith"
var pattern = /^([a-z-]+)s+([a-z-']+)$/gi;
name = name.replace(pattern, "$2,$1");
name = name.replace(/,/, " ");
I have created this form. I would like to use javascript to mail the form to the selected email from the selection list when the submit button is pressed.
<form name="Contact Us" id="contact" action="mailto:" method="post">
<fieldset id="selection">
Who would you like to email:
<select>
<option value="email1" >email1</option>
<option value="email2" >email2</option>
<option value="email3">email3</option>
</select>
<fieldset id="Name" >
Name
<input type="text" id="firstname" name="firstname">
E-mail
<input type="text" id="email" name="email">
</fieldset>
<fieldset id="question">

<input type="text" id="comment" name="comment" style="width: 500; height: 300">

</form>
I'm trying to create a form where the user enters data in a field and is redirected to a URL based on that entry - example: user enters 1234 and he is directed to mypage.com/1234/index.htm - if that folder does not exist it would give a 'try again' error.

I am trying to find a way to add an extra piece of hidden text onto the end of the text a user enters into the form field so that when the form is sent the extra text will automatically be added to the end before sending. I have tried cobbling together different scripts using onblur/onclick etc but I just cannot get any to work as I need..
View 1 Replies View RelatedI am looking for a general purpose javascript snippet that enables me to
<div> or <span> HTML to make portions of the form be hidden and then appear.
The form contains about 12 sections and some sections can contain
subsections. When the user clicks on a checkbox, I want previously hidden
text boxes, radio buttons, text, drop down menus, and additional checkboxes
to appear. In some cases, clicking on a checkbox in a section can cause
additional previously hidden text boxes, radio buttons, text, drop down
menus, and additional checkboxes to appear.
Within each section, a list of individual names is displayed with an initial
checkbox beside each name being displayed. Clicking the checkbox beside a
name is what triggers the hidden info to be displayed. The server side
application is written in php and the field names are assigned using
brackets as the array is created. As an example the HTML checkbox beside
the first name <input type='checkbox' name='sect1custname[1]' value'First
Name'> The HTML for the next name woud be exactly the same except the name
field would be defined as name='sect1custname[2]'. All of the other input
buttons, boxes, menus, and text would use the same naming conventions so
that the server side module can correctly process the data.
I am hoping to keep this as generic as possible so that we can add, change,
and/or delete entire sections simply by creating the appropriate HTML and
surrounding it with the correct <div> or <span>. I understand that there
may need to be some javascript wrapped around the checkboxes.
If you know of , or have, or can develop the code, please send particulars

the code, just let me know what they are. If you have any questions or need

I am trying to setup a donation form for a friend, where someone can click radio buttons for set donation amounts, or click the "other" radio buttons and enter a different amount. The donation amount is then passed over to a secure credit card entry page, hosted by a 3rd party merchant.I can set up all the pre-defined radio buttons to correctly pass on the donation amount to the credit card page, but I cannot figure out how to work the "other" radio button amount.

When i click once on a button, i create one picture on the fly. And so on. It works ok. Then, using livequery, when i click on one of the all created pictures, i would like to see it removed. But it appears that only the first pic is removed (since all have the same name). What is my mistake ?

I have created an array that holds three textmessages, how can I
remove the created textNode and feed the next message in line? Is
there also an issue with cleaning any whitespace too?
A code snippet:

var altTextBanners = new Array(
"myText1",
"myText2",
"myText3");
altTextBanners.currentIndex = -1;
function initRotate() {
if (!document.getElementById) return;
altTextBanners.currentIndex++;
var text = document.createTextNode(altTextBanners[altTextBanners.currentIndex]);
var message = document.getElementById("message");
message.appendChild(text);
// how to remove the created TextNode and get the next one in the array
// ... ??
}

How can we remove the empty values while displaying the output or how we can remove the spaces from array+
I wonder if there any better method to check if the element in array B exists in array A, then remove it from array A.
Code:
var arrA = ['a','b','c','d','e']
var arrB = ['c'];
I copied and modified this code from somewhere I got it online, but not sure if I understand it as it has two for-loops in it...
Code:
for(var i=0;i<arrA.length;i++) {
for(var j=0;j<arrB.length;j++) {
if(arrB[j] == arrA[i]) {
var index = arrA.indexOf(arrA[i]);
}}}
code to remove element from array A,
Code:
if(index >= 0){
arrA.splice(index,1);
alert(arrA.join(" "));
}
After sorting an array, is this the best way to Remove duplicate array elements?
HTML Code:
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
Code:

Is there a built in method to remove empty array elements?
View 2 Replies View RelatedI'm trying to figure out how I replaces/removes parts of text in string in realtime using jQuery. This is what I got now:
PHP Code:
$str = 'This is a <b>test</b>. Its not going well!';
echo '<div class="element">';
echo '<span>'.$str.'</span>';
echo '</div>';
echo '<p>Remove</p>';
Code JavaScript:
$('p').click(function() {
$('.element span').each(function() {
var test = array('<b>','</b>','well');
//var test = 'not';
console.log($(this).text());
var text = $(this).text().replace(test, '');
$(this).text(text);
});
});
The problem: As above nothing happens. If I use the var test = 'not'; instead of the array part it works except it also removes the <b> tags? How do I get the array part to work and why is it removing htmltags when executed?
