JavaScript - Limit And Edit Character Input

Is it possible to limit a textarea input with a max amount of letters?

So if the form said 1,000 character limit. Can it block it after the 1,000th one is reached?

Dear Friends,
please give your solution about below problem. I call

function test".$i."(){
edit($('$paket_id'));
}

function for editing in line text.

<div onclick="test".$i."(this)"><img src="./images/edit01.png"></div>

But when I click to call link, the textarea are opening again. How I can limit this?

Hi Im new to javascript and need some help with a project I have, the task I have is:

Create a page that can take a bloke of text and out put the following
o How many times each letter occurs
o How many spaces
o How many words
o How many times each word occurs
o A list of things that are not words or special characters

I think maybe use an array but im not sure, like I said im new to this so not too sure on how to do it. I know it would read into a file say a txt file and sort through it this way, possibly using some kind of loop to read through all of the text before sorting it and I know it might use variables. I know how to kind of work through the task I have, but to actually implement the mechanics of the javascript is something that I then struggle with
Thanks to all that help.

Specifically i was wondering if anyone had any ideas on how to select the specific character when hovering over a word?

I have not been able to find any documentation on this however, there is a demo site i found for a plugin that allows character selection.

i dont need anything that large and elaborate...

Edit I'm pretty wel experinced with jquery, I know it's possible with jquery

Hello all,

I need assistance checking for valid characters in a username/password set up. I have been reading up on form validation but can't find exactly what I am looking for and need help deciphering what's going on.

I have a list of accepted characters: "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.-_@"
a-z, A-Z, 0-9, dot, dash, underscore, and at.

I want to then check an inputed string against that set and if a character is notin the accepted set, to send an alert.

Here is what I have gathered so far: a for loop that increments through the values' .length - this is what checks each individual character. Then use of indexOf() can tell me which character is unacceptable. Now is where I am stuck and coming to you. Please help

Hi All

I am not a genius when it comes to javascript so if anyone could help, I would really be grateful.

scenario:

I am creating a custom product (75g) which will be made up of 3 others products (25g + 25g + 25g). The 3 options will be made up of a combination of smaller products each with their own options (25g, 50g, 75g) which will allow the customer to have one of each or fill up all 3 with just one type.

Here is what I have in code already:

Code:

<div class="wrapperAttribsOptions">
<h4 class="optionName back">Organic Sour Worms</h4>
<div class="back">
<input name="id[14][48]" value="48" id="attrib-14-48" type="checkbox"><label class="attribsCheckbox" for="attrib-14-48">25g</label><br>
<input name="id[14][49]" value="49" id="attrib-14-49" type="checkbox"><label class="attribsCheckbox" for="attrib-14-49">50g</label><br>
<input name="id[14][50]" value="50" id="attrib-14-50" type="checkbox"><label class="attribsCheckbox" for="attrib-14-50">75g</label><br>
</div>
<br class="clearBoth">
</div>

<br class="clearBoth">

<div class="wrapperAttribsOptions">
<h4 class="optionName back">Organic Sugar Bears</h4>
<div class="back">
<input name="id[15][51]" value="51" id="attrib-15-51" type="checkbox"><label class="attribsCheckbox" for="attrib-15-51">25g</label><br>
<input name="id[15][52]" value="52" id="attrib-15-52" type="checkbox"><label class="attribsCheckbox" for="attrib-15-52">50g</label><br>
<input name="id[15][53]" value="53" id="attrib-15-53" type="checkbox"><label class="attribsCheckbox" for="attrib-15-53">75g</label><br>
</div>
<br class="clearBoth">
</div>

<br class="clearBoth">

<div class="wrapperAttribsOptions">
<h4 class="optionName back">Organic Fruit Cocktail</h4>
<div class="back">
<input name="id[16][54]" value="54" id="attrib-16-54" type="checkbox"><label class="attribsCheckbox" for="attrib-16-54">25g</label><br>
<input name="id[16][55]" value="55" id="attrib-16-55" type="checkbox"><label class="attribsCheckbox" for="attrib-16-55">50g</label><br>
<input name="id[16][59]" value="59" id="attrib-16-59" type="checkbox"><label class="attribsCheckbox" for="attrib-16-59">75g</label><br>
</div>
<br class="clearBoth">
</div>

<br class="clearBoth">

<div class="wrapperAttribsOptions">
<h4 class="optionName back">Organic Jelly Bears</h4>
<div class="back">
<input name="id[17][57]" value="57" id="attrib-17-57" type="checkbox"><label class="attribsCheckbox" for="attrib-17-57">25g</label><br>
<input name="id[17][58]" value="58" id="attrib-17-58" type="checkbox"><label class="attribsCheckbox" for="attrib-17-58">50g</label><br>
<input name="id[17][60]" value="60" id="attrib-17-60" type="checkbox"><label class="attribsCheckbox" for="attrib-17-60">75g</label><br>
</div>
<br class="clearBoth">
</div>

What I need to do is to some how ensure that the product is filled with 75g worth of the other products.
Another option may to not use the 'grams' but rather use the 3 compartments that will be filled so 25g = 1, 50g = 2, 75g = 3 etc.

Note: Name, Values, Ids are made dynamically by the cart, and I cannot change those as they are used for adding to cart and updating account info etc.

PLEASE PLEASE PLEASE if anyone can help, I would really appreciate it.

Thank you for your help with this. I am newer to JS and appreciate the assistance.

I am using iScroll for an image gallery on the iPad. I can place 120 columns equalling 122,880 pixels in width. After that the content fails to display. How can I get additional 180 columns that I have to display?

Hello,

Is there any way that I can add a limit for the amount of time that a javascript loader bar stays on screen?

The specific loading screen I am using is http://www.fliesen-info-spanien.net/loadbox.php.

This loading box actually activates once the page is loaded apparently, but in my instance, it is loading then disappearing in the matter of a second, but I wouldnt mind leaving it up for a couple of seconds, say 3-5.

Is there any line of code I can add to do this?

hi, i am now playing with the time.
can you please tell me how to make the time move in downwards, i mean a countdown like format, e.g the time will start countdown and end in 2 days?

here's my initial noob code for creating time

Code:

<script type="text/javascript">


var today = new Date();
h = today.getHours();
m = today.getMinutes();
s = today.getSeconds();

function showDate(){
  if(document.getElementById('but').value = "locked"){
    h = checktime(h);
    m = checktime(m);
    s = checktime(s);
  }
  document.getElementById('t').innerHTML = h +":"+m+":"+s;
}

function checktime(i){
  if(i < 10){
    i = "0" + i;
  }
  return i;
}

function ocl(){
  var x = true;
  if(x){
    document.getElementById('but').value = "locked";
    showDate();
  }
}
function mo(){
  document.getElementById('but').value = "lock me ?";
  x = false;
}

</script>


<h3>
<a id="t"></a>
</h3>


<input type="button" id="but" value="unlocked" onmouseover="mo();" onclick="ocl();" />

I have a script which allow a user to move users from one multiple selectbox to another and it works fine, but...

I want to be able to restrict a user to only move x amount of users from one box to another. I want to create an alert when the user try to add a user to much...

The javascript:
Code:

  $().ready(function() {
   $('#add').click(function() {
    return !$('#box1 option:selected').remove().appendTo('#box2');
   });
   $('#remove').click(function() {
    return !$('#box2 option:selected').remove().appendTo('#box1');
   });
  });

The HTML:
Code:

<table>
	<tr>
		<td valign="top"><select multiple id="box2" style="width:250px;height:200px;"></select></td>
		<td width="100%" align="center"><a href="#" id="add">Add</a><br><a href="#" id="remove">Remove</a></td>
        <td valign="top">
        	<select multiple id="box2" style="width:250px;height:200px;">
        					<option value="1">User 1</option>
                            <option value="2">User 2</option>
                            <option value="3">User 3</option>
                            <option value="4">User 4</option>
           </select>
        </td>
	</tr>
</table>

Hope this makes sense... Thanks in advance...

Suppose I have the string 'ello'.
I want to insert the letter 'h' in the beginning of that string.

How do I do that without using a special function? I can only use the functions charAt and indexOf - anyone has any idea?

Ok

I have a textarea field that is validated by Js, this textarea can and will contain the newline character

Code:

\n

so I validate in JS Code:

if(textareaname.value.length < 200)

this hten goes through to my php where i also check before I place in to the Database using MYSQL

Code:

if( strlen($_POST['textareaname']) < 200 )

but my php is giving me a different string length from my javascript.

It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.

I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.

Any ideas? Any suggestions as to how I can make php and javascript treat a newline as the same amount of characters?

Thanks in advance.

So say if my string was..

Code:

a = "Hello";
alert(a);

How do I get it to say;

Code:

alert("ello");

So how do I take off the 'H' in this example..
