Clone Element, After Row 10 Random Numbers	View Content

Hello all,

I hope someone can help me with this.

I have a form wich has a add/remove row button, this so the visitor can select multiple sets of data. All is fine and is being submitted via PHP.

Only problem is from number 10 and up, i am getting strange random numbers in the new rows that are added in their name. Like 1111 (instead of 11), 122222 (instead of 12). And because of this, every row from 10 and up won't be send through php, giving this random effect.

I can't seem to find why this is happening.

Hopefully someone can help me out in this.

The full form can be viewed

http://www.multisearch.info/test/form_ruby_2.html

The code i use for my Clone Element is

Code:

//clone element
var clone;
function cloneRow(row){
clone=row.cloneNode(true);
}

function addRowToTable(row){
var tbody=row.parentNode;
var inputs=clone.getElementsByTagName('input'), i=0, inp;
i=0;
while(inp=inputs[i++]){
	if(inp.type=='text'){
	inp.onfocus=function(){this.value='';}
	}
	if(inp.type=='button'){
	inp.value=='Add'?inp.onclick=function(){addRowToTable(this.parentNode.parentNode)}:inp.onclick=function(){removeRowFromTable(this.parentNode.parentNode)};
	}
}
tbody.appendChild(clone);
cloneRow(tbody.getElementsByTagName('tr')[tbody.getElementsByTagName('tr').length-1]);
reorderNames();
}

function removeRowFromTable(row){
row.parentNode.removeChild(row);
reorderNames();
}

function reorderNames(){
var rows=document.getElementById('tblSample').getElementsByTagName('tbody')[0].getElementsByTagName('tr'), r, i=0, el, e, j;
while(r=rows[i++]){
	el=r.getElementsByTagName('*');
	j=0;
	while(e=el[j++]){
		e.nodeName=='SELECT'||(e.nodeName=='INPUT'&&e.type=='text')?e.name=e.name.replace(/\d/,i):null;
		}
	}
}

onload=function(){
var row=document.getElementById('tblSample').getElementsByTagName('tr')[0];
cloneRow(row);

Generating A Random Between 2 Numbers [help!]

1st, Hi Coding forums!

I'll get to the point, I'm a noob -.-

I'm using greasemonkey for a certain website.

Basically, I'm using gm to refresh the page after a certain time, I was however wondering, If I can set it to a random number between 2 specific times?

The code I'm using atm is

setTimeout(function() { document.location.reload(); } , 10000);

I know I have to use math.random, well, I think I do. But I'm not sure how to do it between 2 certain times?

So to summarise, I'm trying to refresh a page at any given random time between say 5-10 minutes.

Any help is appreciated, thanks!

How do I add the 3 separately generated numbers together to show the total??

Here is my code so far. Specifically I would like to add the myNumber1(), myNumber2() and myNumber3() results together.

myNumber2D();
myNumber3D();

i have a table with a couple random numbers, and i want to click a button that will dynamically regenerate the numbers each time the button is clicked without re-generating the entire table., im using DOM and innerhtml for these random numbers. heres the javascript and html code. so far, it just generates the random numbers when the page loads.

var random2 = Math.floor(Math.random()*40 + 1)
var random3 = Math.floor(Math.random()*40 + 1)
var random4 = Math.floor(Math.random()*40 + 1)
var random5 = Math.floor(Math.random()*40 + 1)
var random6 = Math.floor(Math.random()*40 + 1)

//create table
function makeTable(lotto)

document.getElementById("tableSpan").innerHTML = '<table border="1" id="lotto">';

I am trying to create a javascript code in which I prompt the user for a number (an integer from 0 to 100) to search for, then search a function with the number they entered and then display whether the number was found, and if found, a location where it can be found within the list.

Random Element Id Help

Alright, I need a little help with my javascript. I'm a bit of a novice when it comes to programming so I apologize if this appears trivial.

I have an element ID that begins with bb + a randomized number between 1-100,000. This number changes after every action so what I need is a way to retrieve this new value each time and implement it into my code. I can view the number using firebug but I need a way to automate this process. Do any of you have some advice about how I could approach this problem?

How To Prevent Repeating In A Random (math.random) Array?

Similar Tutorials

View Content

I've looked for a solution to this issue, but it seems like a little different scenario than other situations.

I made a system for generating friend requests on Facebook. I have a grid that is 6 x 3, for a total of 18 cells. Each cell has a picture in it, and the picture is linked to the Facebook friend request page. My problem is that since each cell is populated at random from the array, I'm getting lots of repeats. For example, some picutures are in 5 cells, and some are in none. I'm trying to figure out how to make it so that once a picture is used once in the grid, it does not get used again in the same grid. I still want every cell filled at random on each page load, I just want to prevent the repeating.

Here's my current code:
Code:

How Do I Load A Link Inside A Div Element Into The Same Div Element

Hi, I'm relativly new to JS and brand new to the forum so you might need to dumb down your replys for my slightly lacking knowledge. That being said I do have a very solid grasp of html, css and am getting there with JS and its various frameworks.

I'm integrating wordpress into an existing site for a friend and currently have the main blog page appear in a DIV. This is the best way to integrate in this case due to many reasons mostly of way the site is constructed.
Code:

<div class="scroll-pane" id="scrollbox">
	WORDPRESS BLOG		     
</div>

My issue is that links within that DIV, in the blog, when clicked redirect the page. The simple answer to this would be to have them just open in a new page, which I can easily do with the below code.

Code:

function Init()
{
  // Grab the appropriate div
  theDiv = document.getElementById('scrollbox');
  // Grab all of the links inside the div
  links = theDiv.getElementsByTagName('a');
  // Loop through those links and attach the target attribute
  for (var i=0, len=links.length; i < len; i++) {
    // the _blank will make the link open in new window
    links[i].setAttribute('target', '_blank');
  }
}
window.onload = Init;

But what I'd rather it do is have any link clicked inside the DIV to reload in that same DIV, similar to an iframe, but obviously without using an iframe, due to it's compatibility issues.

Is this possible by editing the above code? If not what do I need?

Thanks in advance for any help!

Basically I want to be able to enter a number on the page or in a message box then I want the code to add all the numbers from 1- the number I enter.

The code I got from my previous thread is he
Code:

<script type="text/javascript">

var varX = user input;
function sum() {
   var varX = user input;
   for(varY = 1; varY<=10; varY++) {
      varX = varX + varY;
   }
   return varX;
}

var resultat = sum();
alert(resultat);         // show message box with result

What I want to do is add more word lists. This of course is easy in principle - I can just continue the lists like:

form.title9.value = "";
form.title10.value = "";
form.title11.value = "";

- and so on. The problem is that, in the "sentence patterns", I cannot use numbers with two digits to refer to the word lists. Then it thinks I mean 1+0 and 1+1 instead of 10 and 11. How can I allow this? I have heard about using regular expressions to "capture the number by its word boundary" - is this a good solution? If yes, can someone please explain to me how to do it? (I have tried special characters like @,#,$ and more as well as Russian and Greek letters. This makes the script unable to generate poems.)

Thank you.

Convert the string values which are concatenated by + (e.g. "2" + "5" = 25) into numbers (e.g. 2+5 = 7) by using the Number() method, or another way is to multiply the value by 1.

But you are using string values
if (chr == '1') {
quite unnecessarily.
Remove the quote marks to make them into numbers.
"1" is a string value. 1 is a number

Obviously chr = pattern.charAt(ichr); only captures a single numeric chararcter.
You can extract two-digit numbers from a string just by removing all non-digits
var x = str.replace(/[^0-9]/g,""); // strip all characters but digits
That of course assumes that there is only one number in the string.
